Tangshan earthquake desolate heart of many people, comparison, the deceased have died, the living have struggled to live. the soul would not know how to wait for the return of perseverance, the firm do not know Debu abortion. But the movie every woman both strong and good to captivate us, let us again and again shed a tear. that the end of her life personally Li Ni, day and night guarding her husband and her daughter's soul, but still away for the entrance of the son of the refrigerator, with the strong silent mending of life. Yuan Ni's mother lost a son in an instant, the kind people who sent hair hair pain imagine, but in the end, she understand the daughter, leaving the grandson back home alone. party posted on the earthquake left a huge scar in her heart has always believed that young its abandonment, when the decision to give birth to her daughter, she suffered a boyfriend but abandoned again, and she and her daughter by working to support themselves, and ultimately out of the shadows, to forgive his mother, forgive the man, who excused himself. adoptive mother board side age is still light on the terminally ill, knowing that time is running out, she did not collapse, but sympathize with his wife and daughter. another big earthquake, but also a mother decided to give up her daughter's legs, and she cried her piercing, but her feelings of maternal love for her daughter even more reluctant to seize other people's lives and children, as she and meta-ni, at the last moment, with hard and strong will to make a choice. natural disaster like a slap in the face, almost unconscious with pain, and we do not know what happened. But the film all the women, all standing have not been buried, they used a silent but powerful way to fight the, re-build the house, built in Tangshan, the courage to build the students.
there are many women, although not suffered a major earthquake, but also experienced a different kind of disaster. sixty-year-old, still care her four-year-old son. Yes, she used the care of her life from birth to understand the ways of the world can not take care of their children, even if she had sixty-year-old senior citizens, even if her son has been an unmitigated middle-aged man, but he is always in her eyes was a child, she exhausted all the possible care for him. an ordinary villager Xin Yan Jin, a lifetime to serve the disabled husband, and brought a pair of children, for they went to college. a Name poor cleaners, an orphan adopted, but stricken cut off relations with her two sons, from indifferent to her, but she never regretted his decision, on the adoption of orphans as her own child. A woman lost forever in the abortion rights of the mother, it is a kind of pain and regret, but she is still strong in life. No matter what kind of combat and suffering, these women did not complain, did not fall. can said that God has given us many kinds of misfortune, how many gave us a strong woman.
sometimes a disaster like thunderstruck, like earthquakes, like the collapse of rapidly changing our lives. and sometimes, pain and like a tug of war, When a long game with. like ordinary you and I, although not encountered that sudden unfortunate, but life is not satisfactory. every woman, more or less in life to experience pain, It looks like tiny, seemingly not lethal, but in fact only the really experienced people know that physically and mentally exhausted. an ordinary woman Lu Chen, 39, is an accountant and looks usually sparse, and only her he knows how to carry through life, cold .19 each age of her first love, to pay all the dedication and half a year later found to be a hoax, is the simplicity of black and blue after she has been, or will in every night .25-year-old production of miss each other when she suffered giving birth, family, and even wanted to give up the child, she resolutely adhere to risk their lives, the first tone before heading for the big kids crying. Remember the age of the child of a high fever, she was anxious round and round, but also so an argument with her husband .32-law age of primary school children cried and ran home to tell her someone has a toy and he did not, she should not teach children and students competition, but their hearts are like knives cut, which the mother did not want to give children the best living environment? watching other children what their children are not, is an indescribable hatred of his feelings .35 years old, her husband began to night out , a small three problems have been unavoidable, she was terribly wronged, looking at his pining away for this family faces, watching the child is still innocent face, she suddenly did not know the dignity and the family which is more important when the .38-year-old , is a meeting she received the bad news, the mother collapsed in the bathroom, there is no danger, she only felt dizzy, the way to go the hospital are a child of the scene, really made a mother, and understand the mother for their love and hard work. As such, she has been at the hospital and go home on the road, everyone is a woman, and no one will inevitably encounter a disaster and disease, can have strong and went to the hospital, to face to solve every crisis and 不如意.
woman so sensitive, so when faced with emotional loss, betrayal or abandonment, they also came under Xiangdui more pain. But women always use their own way to resolve the grief. maybe they will cry, but crying will then walk proudly to face; maybe they will talk, but talk to their full strength after; maybe they will, got drunk, but they will be ready after waking. Yes, maybe They sometimes seem soft, but soft and not weakness, but the face of difficulties indomitable tough temperament.
strong woman is not rock, not heavy rain, not the days of cries and ringing in the attack, but a stubborn, with the cruel fate of long-term view, is a dark, silent condemnation. they do not change the dress, silent no effort to extend the ring to life with the ultimate fate of ill break the arrangement. When you spread out on the age of a woman's palm, you will be her story and shocked by the tough but actually appear to be normal mm it is difficult to hand over the pattern of a Road. a woman's beauty is also here, in the stone, then the stubborn stone, but also by not live in a silent but powerful woman soaked.

Inside VC Notes (1)
The first day:
WINDOWS application must be WinMain function, which is used to complete some specific task, like creating the main window, the main window code to handle the message. MFC WinMain hidden in the framework will not SDK to write programs as you can easily find it.
WINDOWS message handling mechanism used by the program to the framework, we do not have to worry about how to link these messages and codes. And some news WINDOWS defined, when the window When the system is created WM_CREATE message is sent when they click the left mouse button the system will send WM_LBUTTONDOWN message, when the user presses the keyboard, the system will send WM_CHAR message, when the user closes the window, the system will send a WM_CLOSE message, when the user menu options or click the button to send a WM_COMMAND message when the system back, do nothing the system will send WM_TIMER message. I will not speak anything else, first find out that these messages say. from MSDN can easily find on this several messages with the help of documentation.
WINDOWS provide a common graphical device interface (GUI), we have by calling (GDI) functions, and hardware to deal with, without regard to equipment, environment, WINDOWS environment, the device automatically mapped to the corresponding physical structure, equipment This should be the device-independent nature of it.
dynamic link library (DLL) should be a classic example of code reuse (do not know can not say), the number of modules, their own separate class of newly commissioned and compiled into a DLL, and increase the readability of the code also increased the flexibility of the program modules.
Developer Studio create the project with the Developer Studio will create a lot of intermediate files that still need to talk about the.
APS / / support ResourceView < br> BSC / / browser information file
CLW / / support ClassWizard
DSP / / project file can not be deleted, and with a text editor to edit
DSW / / work space files, can not be deleted, and with a text editor to edit
MAK / / create the file outside of
NCB / / support ClassView
OPT / / save the workspace configuration
PLG / / create the log file
the role of these documents have a certain , take CLW, if you have a new class, you need to add ClassWizard, in addition to the corresponding. h and. cpp added to the DSP CLW.PLG also need to recompile your project file records the configuration information.
VC + + of the source browser will enable us to class or function from the perspective of knowledge or editing program, rather than directly from the file start. in other people's source code to see if the source code of proficiency in the use of the browser will be less effective. Source The main program view the status of the browser are the following:
Definitions and Referencesmm select any functions, variables, types, macros can see it in the definition of the project, and where and where to use it. < br> Call Graph / Caller Graphmm for the selected function, given its function of calling and being called an icon.
Derived Class Graph / Base Class Graphmm gives graphical representation of class hierarchy, you can see the selected class and derived class and base class members.
File Outlinemm for the selected file, listing file classes, functions and data members, and also shows the location of the definition and use of their position.
visible Source Brower than the Class View to feature a lot more and more easy to use, before I do not know, because VC + + book in general did not say or no attention to this and see about the menu, user interface, the editor always skip thought, +6 using AppWizard generates an empty procedure, and then try to look at all those files, and their class hierarchy, functions, macros, structure definitions, I was so dry, not hands-on learning programming is not enough. < br> The next day: Microsoft Foundation Classes application framework
MFC is a C + +, Microsoft Windows API, if you want to develop applications WINDOWS course, VC / MFC is the development environment of choice.
MFC applications created a standardized structure. (I still can not see the advantage of this, please master guiding)
MFC application that produces short, fast running speed. It should be said is that it can easily create a dynamic connection, in fact, procedures still need a lot of DLL, but because there are a lot WINDOWS DLL so the application can be very short, I think so I do not know of any.
VC + + tool reduces the coding complexity. This is not to be questioned than the TC convenient too much.
MFC library functions is very rich. the book lists the MFC from 1.0 - 4.21 Some of the features, I do not talk nonsense, we should look at.
This section introduces the MFC advantage of the library, in fact, I think that in certain circumstances as a matter of fact that MFC is not necessarily as good. I want no one to do with pure VC MIS system, it, too tired. I understand this is programmed, If the school program as Weapons words, C / C + + language and programming ideas (OOP) is the internal strength, API is the basic skills (programming idea is that internal strength, API is the basic skills that apply to any WIN32 programming, regardless of Visual C + +, Delphi, C + + Builder, VB ......), VC / MFC martial arts one of them should be different, different learning methods are not effective as long as they make an effort can also be reached a certain level. the real master is to have a profound internal strength, solid basic skills, as martial arts, does not matter, not the small non-random one-stop eight-no flaws, no stroke victory has recruited. apologies to the topic.
C + + class library to be extended through, we can use in addition to compiler provided with the library, can also be easy to use library software companies sell products, or even their own development. and the application framework is a superset of the class library, which defines the structure of the program.
the following to the two sample programs (one is a book I wrote):
Raytheon Recommendation: Although a lot of books with CD, CD on the source code for all examples in the book, but still should be used in person at the VC6 hand and struck into it. This can enhance the impression and feel the correct compile debug programs running after the fun, because it is handmade. Ever since I knocked nearly a hundred code samples, due to clerical error in the BUG on the few, typing speed also increased. and preferably in the original sample code to make some changes on the basis of other monotony of such displays HELLO WORLD! for something else, this can also deepen the understanding of the sample program.
HELLO WORLD I used AppWizard Wizard to create a single document to display a string program, just typing one line statement, mainly to experience the power of MFC.
1, open the VC + +6 from the menu, select NEW, the project named .
2, select the MFC AppWizard [exe] option, in addition to select a single document outside STEP 1 STEP other default.
3, in the Class View selection CMyApp01View class OnDraw () member function in C + + double-click the compiler see the following
void CMyApp01View:: OnDraw (CDC * pDC)
{
CMyApp01Doc * pDoc = GetDocument ();
ASSERT_VALID (pDoc);
/ / TODO: add draw code for native data here
}
in the / / TODO: add draw code for native data here to increase the position of a line of code
void CMyApp01View:: OnDraw (CDC * pDC)
{
CMyApp01Doc * pDoc = GetDocument ();
ASSERT_VALID (pDoc);
pDC-> TextOut (10,10, add draw code for native data here
}
done, simple as that. compile and run. see that? WINDOWS This program has all the features of the program, such as menus, toolbars, status bar, maximize, close and even on the dialog, print preview ..... all, this is the MFC AppWizard created dynamically by an application. From this small example can be seen with the VC / MFC program designed WINDOWS how convenient. Now we see examples of the book in order to further understand the application framework.
book example:
1, first create a Win32 Application application.
2, select Project-> Add to project -> Files, create a file called MyApp.h respectively, and a file named MyApp.cpp.
3, add the code: (best according to the following code to the compiler knock, do not use Ctrl + C / Ctrl + V)
/ / MyApp.h
/ /
class CMyApp: public CWinApp / / see below ②
{
public:
virtual BOOL InitInstance ();
} ;
class CMyFrame: public CFrameWnd
{
public:
CMyFrame ();
protected:
afx_msg void OnLButtonDown (UINT nFlags, CPoint point);
afx_msg void OnPaint ();
DECLARE_MESSAGE_MAP ()
};
/ / MyApp.cpp
/ /
# include br> CMyApp theApp; / / create a CMyAPP object below ②
BOOL CMyApp:: InitInstance ()
{
m_pMainWnd = new CMyFrame ();
m_pMainWnd-> ShowWindow (m_nCmdShow);
m_pMainWnd-> UpdateWindow ();
return TRUE;
}
BEGIN_MESSAGE_MAP (CMyFrame, CFrameWnd)
ON_WM_LBUTTONDOWN ()
ON_WM_PAINT ()
END_MESSAGE_MAP ()
CMyFrame:: CMyFrame () {
Create (NULL, )
{
CPaintDC dc (this);
dc.TextOut (0,0, it? MFC had not added the support options in Project Setting General Properties page select the Some elements of the program.
① WinMain function: not only does not exist have been hidden within the framework of the application.
② CMyApp categories: CMyApp class object represents an application, CWinApp base class to determine its most behavior.
③ start the application: When running an application calls the WinMain function WINDOWS, WinMain will find the application of the global object theApp.
④ CMyApp:: InitInstance member function: that is automatically called after the overloaded theApp virtual function InitInstance to complete the construction of the main window and display work. Remember this function.
⑤ CWinApp:: Run member function: WinMain calls immediately after the call to InitInstance Run function, which is hidden in the base class is responsible for transfer applications The message to the matched window. (I understand it as if the window procedure function SDK do not know right)
⑥ CMyFrame class: This object represents the application's main window. It's base class constructor calls CFrameWnd the Create function to create a specific window structure.
⑦ CMyFrame:: OnLButtonDown function: Demo message handling mechanism, when the mouse button is pressed to sit in this event is mapped to CMyFrame the OnLButtonDown function, if you choose F5 to compile and run then you can see the TRACE macro in the debug window displays information similar to the following
Entering CMyFrame:: OnLButtonDown - 1,309,119
Entering CMyFrame:: OnLButtonDown - 1,408,221
⑧ CMyFrame:: OnPaint function: application to re-draw each time window needs to call this function, will display (this);
dc.TextOut (0,0,
{
TRACE (dc (this);
dc.TextOut (0,0, Minimize the window and then maximized Finally, remove the CMyApp object.
by the above example we see most of the features included in the program CWinApp and CFrameWnd base class, we just write a few functions, we can complete very complex functions. so the application framework is not only is only a library, it also defines the structure of the application, in addition to the base class also included the WinMain function, and to support the message processing, diagnosis, DLL, and so included in the application framework.
third : Message map and view class notes
after writing the two friends gave me a lot of letters, and I share some of the problems in the learning process. but I am also a beginner, some of the issues themselves are not sure Therefore, it is not pop star, but I will try to do my best to study with everyone, thank you for the encouragement and confidence.
at the beginning of the first to add content on a Tiange netizen's question and answer (if Tiange brother can see it). In order to simplify the code, we see a more simple, only one file, create a blank window, and do nothing. Note Well: I'm writing a program or to be divided. h and. cpp file more clear two.
front steps and 『』 Inside VC + + Study Notes (2) the same, the following is the code:
/ / MyApp.cpp
# include > {
public:
virtual BOOL InitInstance ();// overloaded virtual function InitInstance
};
class CMyFrame: public CFrameWnd / / inherited from CFrameWnd class
{}; < br> CMyApp myApp; / / finally activate the application's constructor
BOOL CMyApp:: InitInstance ()
{
m_pMainWnd = new CMyFrame;
/ / new class constructor activated CMyFrame CFrameWnd (), also used constructor tune CREATE ()
/ / m_pMainWnd defined in the MFC CWnd * m_pMainWnd; / / main window (usually same AfxGetApp () -> m_pMainWnd)
/ / m_pMainWnd save the window position
((CMyFrame *) m_pMainWnd) -> Create (NULL, screen
return TRUE;
}
see if the proposals do not understand or see MSDN master Hou layman. on this issue to this point, the last of the Tiange friends to pay tribute to the attitude of learning. < br> The following entry is the body, let us continue to look at MFC's message map.
MFC through some of the macro to a specific message alluding to the corresponding derived class member functions, the benefits of this system is to allow certain non- window class (such as document type) to control the command message. and does not require any expansion of C + +.
MFC control function requires the message to provide the function prototype, the function body and the message map entry. really a lot of trouble, better use Class Wizard can be easily added to the above mentioned things in our class. For example, as long as the Class Wizard to add WM_LBUTTONDOWN message, then the code will be added to the right place. how about it a lot easier.
In addition to the application framework that contains the application class, in general, but also contains the document and view classes. This document - view architecture is the core application framework. I've been MIS development, certainly not with the VC is used VB, so to see it I do not consciously think of the relationship between back-end database and interface, this example may not be appropriate, but it can very well help us to understand documents and views. documents like the background database, view the contents is displayed on the screen, the same database can be displayed with a different interface, but because of all the interface data content is derived from the database, so when the database changes, the interface displays all the relevant changes will follow. more do not think it appropriate, but can not think of other examples of the. our application is actually the view of the document through a series of operations, not just output. Here we look at the view class.
view is a class derived from CView class object on the screen is a display window. the object of the act entirely by class member functions and data members of the decision, and which includes a specific function in the derived class, including the standard base class function, understanding the structure of MFC class library and a variety of how important the standard member function ah, do not bother to read the source code for MFC recruited to see how many count the number, but certainly not the white look, this is the experience of Raytheon.
I remember the example of an up
1, open the VC + +6 from the menu, select NEW, the project named > MFC application framework at this time would help us to complete the application, you can run it, it will be displayed on the screen style of a typical WINDOWS blank window.
project we look at where the program files directory:
myapp01.dsp / / project file
myapp01.dsw / / work space file
myapp01.rc / / resource description file
myapp01View.cpp / / class member function contains CMyAppView view class implementation file Key
myapp01View.h / / class member function contains CMyAppView view class header file key
myapp01.opt / / binary file that tells what Developer Studio project file is the open, but also how to arrange the
readme.txt / / used to explain all the files generated, not listed myapp01Doc.cpp, myapp01Doc.h, StdAfx.cpp, StdAfx.h .... can be found here accordingly.
resource . h / / include # define constants defined in header files
closer look myapp01View.cpp and myapp01View.h files, programs, classes in the core CMyAppView defined in two documents, that we are to learn the view class. To see CMyAppView class picture, should be Source Browser view, select CMyApp01View, press Alt + F12, select the Base Class and Members option. we will see CMyAppView class hierarchies (where he comes from too), and all member functions, including inherited from the base class (not shown in the Class View in the parent class member functions). We found that in fact you have nothing to do to have a class with powerful features.
Here we look at CMyAppView OnDraw member of the class function, which is the role of virtual function to be redrawn whenever the window when the application framework will call it. Its prototype is like this (can be found in the myapp01View.h)
virtual void OnDraw (CDC * pDC); / / overridden to draw this view
parameter is a pointer to CDC class, WINDOWS and windows through the device associated with the environment (CDC class object is the device context) and display hardware for communication. With this pointer we can call the CDC class member function to do the work of a variety of drawing, as indicated in a used textout () and some Ellipse (), Polygon (), BitBlt () so long in the MSDN has an article, it is directly from CObject derived, well we started in the OnDraw () to add some graphics work.
3, in the Class View selection CMyApp01View class OnDraw () member function in C + + double-click the compiler sees the following
void CMyApp01View: : OnDraw (CDC * pDC)
{
CMyApp01Doc * pDoc = GetDocument ();
ASSERT_VALID (pDoc);
/ / TODO: add draw code for native data here
}
In the / / TODO: add draw code for native data here to increase the position of a line of code
void CMyApp01View:: OnDraw (CDC * pDC)
{
CMyApp01Doc * pDoc = GetDocument ();
ASSERT_VALID (pDoc);
pDC-> TextOut (10,10,
pDC-> Ellipse (CRect (20,40,120,140)); / / draw a circle, CRect is the MFC library provides a class that rectangle WINDOWS
pDC-> Rectangle (CRect (220,240,120,140)); / / draw a rectangle
/ / TODO: add draw code for native data here
}
compile and run, the success of it. first it right. Another future article will also be posted on the writing area.
s Four: Resources and compiled
resource files (that is, to apply the program name and extension. rc files) largely determines the application's user interface. In VC + +, resource files include the following:
Accelerator / / simulate the choice of menus and toolbars content
Dialog / / dialog box layout and content
Icon / / icon, there are two one is 16X16 one is 32X32.
Menu / / application belongs to the main menu and pop-up menu
String table / / string does not belong to C + + source code for part of the
Toolbar / / toolbar.
Version / / program description, version, supported languages information. < br> The above information are. rc file contains at the same time. rc file also contains the following statement:
# include is suitable for all applications to a number of common MFC library resources include it.
use on the resource editor is not to say, because its operation is very simple to note that although an ASCII code resource.h file can be edited with a text editor, one if you use a text editor to edit it, next time when using the resource editor edits may be lost, so we should try in the resource editor in the editing application of resources , the contents of the new resources added back automatically the corresponding position in our program, for example, instead of us worry about resource.h. This is why is it called Visual (visible) one of the reasons.
compile in VC + + two modes, one is the other one is the Release Build Debug Build. the difference between them is that, Release Build does not debug the source code, without regard to the diagnosis of MFC macros, using MFC Release database, compiled ten pairs of applications to optimize the speed, while the Debug Build, by contrast, it allows the source code for debugging, you can define and use the diagnosis of MFC macros, using MFC Debug library, not optimized for speed. so we should be in Debug mode, application development, In Release mode, and then publish the application. In our project there will be a folder Debug folder and a Release folder and intermediate output files were stored files.
diagnostic macro is to compile a program enabling the state tests tools, such as used on the two TRACE macro in the Debug window, you can get diagnostic information you need without having to set the dialog box like the method, at the time of Release of this information is automatically filtered out.
actually debugging an application is a very challenging job, and I believe we have a similar experience, recruited from the Internet or books for a code or source code, that point when we knocked them into the compilation after Deleloper Studio when all of a sudden there numerous errors and warnings, (some of the books of the source code is wrong) that needs patience and experience with VC + + debugging tools available, such as diagnostic macros, set breakpoints, single stepping, etc. We will save a lot of effort. As for the topic should really compile a lot to say, but because of Raytheon's own lack of experience can only speak on the book for a summary, large ...
WINDOWS application must be WinMain function, which is used to complete some specific task, like creating the main window, the main window code to handle the message. MFC WinMain hidden in the framework will not SDK to write programs as you can easily find it.
WINDOWS message handling mechanism used by the program to the framework, we do not have to worry about how to link these messages and codes. And some news WINDOWS defined, when the window When the system is created WM_CREATE message is sent when they click the left mouse button the system will send WM_LBUTTONDOWN message, when the user presses the keyboard, the system will send WM_CHAR message, when the user closes the window, the system will send a WM_CLOSE message, when the user menu options or click the button to send a WM_COMMAND message when the system back, do nothing the system will send WM_TIMER message. I will not speak anything else, first find out that these messages say. from MSDN can easily find on this several messages with the help of documentation.
WINDOWS provide a common graphical device interface (GUI), we have by calling (GDI) functions, and hardware to deal with, without regard to equipment, environment, WINDOWS environment, the device automatically mapped to the corresponding physical structure, equipment This should be the device-independent nature of it.
dynamic link library (DLL) should be a classic example of code reuse (do not know can not say), the number of modules, their own separate class of newly commissioned and compiled into a DLL, and increase the readability of the code also increased the flexibility of the program modules.
Developer Studio create the project with the Developer Studio will create a lot of intermediate files that still need to talk about the.
APS / / support ResourceView < br> BSC / / browser information file
CLW / / support ClassWizard
DSP / / project file can not be deleted, and with a text editor to edit
DSW / / work space files, can not be deleted, and with a text editor to edit
MAK / / create the file outside of
NCB / / support ClassView
OPT / / save the workspace configuration
PLG / / create the log file
the role of these documents have a certain , take CLW, if you have a new class, you need to add ClassWizard, in addition to the corresponding. h and. cpp added to the DSP CLW.PLG also need to recompile your project file records the configuration information.
VC + + of the source browser will enable us to class or function from the perspective of knowledge or editing program, rather than directly from the file start. in other people's source code to see if the source code of proficiency in the use of the browser will be less effective. Source The main program view the status of the browser are the following:
Definitions and Referencesmm select any functions, variables, types, macros can see it in the definition of the project, and where and where to use it. < br> Call Graph / Caller Graphmm for the selected function, given its function of calling and being called an icon.
Derived Class Graph / Base Class Graphmm gives graphical representation of class hierarchy, you can see the selected class and derived class and base class members.
File Outlinemm for the selected file, listing file classes, functions and data members, and also shows the location of the definition and use of their position.
visible Source Brower than the Class View to feature a lot more and more easy to use, before I do not know, because VC + + book in general did not say or no attention to this and see about the menu, user interface, the editor always skip thought, +6 using AppWizard generates an empty procedure, and then try to look at all those files, and their class hierarchy, functions, macros, structure definitions, I was so dry, not hands-on learning programming is not enough. < br> The next day: Microsoft Foundation Classes application framework

ASSERT_VALID (pDoc);

pDC-> TextOut (10,10, add draw code for native data here
}
done, simple as that. compile and run. see that? WINDOWS This program has all the features of the program, such as menus, toolbars, status bar, maximize, close and even on the dialog, print preview ..... all, this is the MFC AppWizard created dynamically by an application. From this small example can be seen with the VC / MFC program designed WINDOWS how convenient. Now we see examples of the book in order to further understand the application framework.
book example:
1, first create a Win32 Application application.
2, select Project-> Add to project -> Files, create a file called MyApp.h respectively, and a file named MyApp.cpp.
3, add the code: (best according to the following code to the compiler knock, do not use Ctrl + C / Ctrl + V)
/ / MyApp.h
/ /
class CMyApp: public CWinApp / / see below ②
{
public:
virtual BOOL InitInstance ();
} ;
class CMyFrame: public CFrameWnd
{
public:
CMyFrame ();
protected:
afx_msg void OnLButtonDown (UINT nFlags, CPoint point);
afx_msg void OnPaint ();
DECLARE_MESSAGE_MAP ()
};
/ / MyApp.cpp
/ /
# include br> CMyApp theApp; / / create a CMyAPP object below ②
BOOL CMyApp:: InitInstance ()
{
m_pMainWnd = new CMyFrame ();
m_pMainWnd-> ShowWindow (m_nCmdShow);
m_pMainWnd-> UpdateWindow ();
return TRUE;
}
BEGIN_MESSAGE_MAP (CMyFrame, CFrameWnd)
ON_WM_LBUTTONDOWN ()
ON_WM_PAINT ()
END_MESSAGE_MAP ()
CMyFrame:: CMyFrame () {
Create (NULL, )
{
CPaintDC dc (this);
dc.TextOut (0,0, it? MFC had not added the support options in Project Setting General Properties page select the Some elements of the program.
① WinMain function: not only does not exist have been hidden within the framework of the application.
② CMyApp categories: CMyApp class object represents an application, CWinApp base class to determine its most behavior.
③ start the application: When running an application calls the WinMain function WINDOWS, WinMain will find the application of the global object theApp.
④ CMyApp:: InitInstance member function: that is automatically called after the overloaded theApp virtual function InitInstance to complete the construction of the main window and display work. Remember this function.
⑤ CWinApp:: Run member function: WinMain calls immediately after the call to InitInstance Run function, which is hidden in the base class is responsible for transfer applications The message to the matched window. (I understand it as if the window procedure function SDK do not know right)
⑥ CMyFrame class: This object represents the application's main window. It's base class constructor calls CFrameWnd the Create function to create a specific window structure.
⑦ CMyFrame:: OnLButtonDown function: Demo message handling mechanism, when the mouse button is pressed to sit in this event is mapped to CMyFrame the OnLButtonDown function, if you choose F5 to compile and run then you can see the TRACE macro in the debug window displays information similar to the following
Entering CMyFrame:: OnLButtonDown - 1,309,119
Entering CMyFrame:: OnLButtonDown - 1,408,221
⑧ CMyFrame:: OnPaint function: application to re-draw each time window needs to call this function, will display (this);
dc.TextOut (0,0,
{
TRACE (dc (this);
dc.TextOut (0,0, Minimize the window and then maximized Finally, remove the CMyApp object.
by the above example we see most of the features included in the program CWinApp and CFrameWnd base class, we just write a few functions, we can complete very complex functions. so the application framework is not only is only a library, it also defines the structure of the application, in addition to the base class also included the WinMain function, and to support the message processing, diagnosis, DLL, and so included in the application framework.
third : Message map and view class notes
after writing the two friends gave me a lot of letters, and I share some of the problems in the learning process. but I am also a beginner, some of the issues themselves are not sure Therefore, it is not pop star, but I will try to do my best to study with everyone, thank you for the encouragement and confidence.
at the beginning of the first to add content on a Tiange netizen's question and answer (if Tiange brother can see it). In order to simplify the code, we see a more simple, only one file, create a blank window, and do nothing. Note Well: I'm writing a program or to be divided. h and. cpp file more clear two.
front steps and 『』 Inside VC + + Study Notes (2) the same, the following is the code:
/ / MyApp.cpp
# include > {
public:
virtual BOOL InitInstance ();// overloaded virtual function InitInstance
};
class CMyFrame: public CFrameWnd / / inherited from CFrameWnd class
{}; < br> CMyApp myApp; / / finally activate the application's constructor
BOOL CMyApp:: InitInstance ()
{
m_pMainWnd = new CMyFrame;
/ / new class constructor activated CMyFrame CFrameWnd (), also used constructor tune CREATE ()
/ / m_pMainWnd defined in the MFC CWnd * m_pMainWnd; / / main window (usually same AfxGetApp () -> m_pMainWnd)
/ / m_pMainWnd save the window position
((CMyFrame *) m_pMainWnd) -> Create (NULL, screen
return TRUE;
}
see if the proposals do not understand or see MSDN master Hou layman. on this issue to this point, the last of the Tiange friends to pay tribute to the attitude of learning. < br> The following entry is the body, let us continue to look at MFC's message map.
MFC through some of the macro to a specific message alluding to the corresponding derived class member functions, the benefits of this system is to allow certain non- window class (such as document type) to control the command message. and does not require any expansion of C + +.
MFC control function requires the message to provide the function prototype, the function body and the message map entry. really a lot of trouble, better use Class Wizard can be easily added to the above mentioned things in our class. For example, as long as the Class Wizard to add WM_LBUTTONDOWN message, then the code will be added to the right place. how about it a lot easier.
In addition to the application framework that contains the application class, in general, but also contains the document and view classes. This document - view architecture is the core application framework. I've been MIS development, certainly not with the VC is used VB, so to see it I do not consciously think of the relationship between back-end database and interface, this example may not be appropriate, but it can very well help us to understand documents and views. documents like the background database, view the contents is displayed on the screen, the same database can be displayed with a different interface, but because of all the interface data content is derived from the database, so when the database changes, the interface displays all the relevant changes will follow. more do not think it appropriate, but can not think of other examples of the. our application is actually the view of the document through a series of operations, not just output. Here we look at the view class.
view is a class derived from CView class object on the screen is a display window. the object of the act entirely by class member functions and data members of the decision, and which includes a specific function in the derived class, including the standard base class function, understanding the structure of MFC class library and a variety of how important the standard member function ah, do not bother to read the source code for MFC recruited to see how many count the number, but certainly not the white look, this is the experience of Raytheon.
I remember the example of an up
1, open the VC + +6 from the menu, select NEW, the project named > MFC application framework at this time would help us to complete the application, you can run it, it will be displayed on the screen style of a typical WINDOWS blank window.
project we look at where the program files directory:
myapp01.dsp / / project file
myapp01.dsw / / work space file
myapp01.rc / / resource description file
myapp01View.cpp / / class member function contains CMyAppView view class implementation file Key
myapp01View.h / / class member function contains CMyAppView view class header file key
myapp01.opt / / binary file that tells what Developer Studio project file is the open, but also how to arrange the
readme.txt / / used to explain all the files generated, not listed myapp01Doc.cpp, myapp01Doc.h, StdAfx.cpp, StdAfx.h .... can be found here accordingly.
resource . h / / include # define constants defined in header files
closer look myapp01View.cpp and myapp01View.h files, programs, classes in the core CMyAppView defined in two documents, that we are to learn the view class. To see CMyAppView class picture, should be Source Browser view, select CMyApp01View, press Alt + F12, select the Base Class and Members option. we will see CMyAppView class hierarchies (where he comes from too), and all member functions, including inherited from the base class (not shown in the Class View in the parent class member functions). We found that in fact you have nothing to do to have a class with powerful features.
Here we look at CMyAppView OnDraw member of the class function, which is the role of virtual function to be redrawn whenever the window when the application framework will call it. Its prototype is like this (can be found in the myapp01View.h)
virtual void OnDraw (CDC * pDC); / / overridden to draw this view
parameter is a pointer to CDC class, WINDOWS and windows through the device associated with the environment (CDC class object is the device context) and display hardware for communication. With this pointer we can call the CDC class member function to do the work of a variety of drawing, as indicated in a used textout () and some Ellipse (), Polygon (), BitBlt () so long in the MSDN has an article, it is directly from CObject derived, well we started in the OnDraw () to add some graphics work.
3, in the Class View selection CMyApp01View class OnDraw () member function in C + + double-click the compiler sees the following
void CMyApp01View: : OnDraw (CDC * pDC)
{
CMyApp01Doc * pDoc = GetDocument ();
ASSERT_VALID (pDoc);
/ / TODO: add draw code for native data here
}
In the / / TODO: add draw code for native data here to increase the position of a line of code
void CMyApp01View:: OnDraw (CDC * pDC)
{
CMyApp01Doc * pDoc = GetDocument ();
ASSERT_VALID (pDoc);
pDC-> TextOut (10,10,
pDC-> Ellipse (CRect (20,40,120,140)); / / draw a circle, CRect is the MFC library provides a class that rectangle WINDOWS
pDC-> Rectangle (CRect (220,240,120,140)); / / draw a rectangle
/ / TODO: add draw code for native data here
}
compile and run, the success of it. first it right. Another future article will also be posted on the writing area.
s Four: Resources and compiled
resource files (that is, to apply the program name and extension. rc files) largely determines the application's user interface. In VC + +, resource files include the following:
Accelerator / / simulate the choice of menus and toolbars content
Dialog / / dialog box layout and content
Icon / / icon, there are two one is 16X16 one is 32X32.
Menu / / application belongs to the main menu and pop-up menu
String table / / string does not belong to C + + source code for part of the
Toolbar / / toolbar.
Version / / program description, version, supported languages information. < br> The above information are. rc file contains at the same time. rc file also contains the following statement:
# include is suitable for all applications to a number of common MFC library resources include it.
use on the resource editor is not to say, because its operation is very simple to note that although an ASCII code resource.h file can be edited with a text editor, one if you use a text editor to edit it, next time when using the resource editor edits may be lost, so we should try in the resource editor in the editing application of resources , the contents of the new resources added back automatically the corresponding position in our program, for example, instead of us worry about resource.h. This is why is it called Visual (visible) one of the reasons.
compile in VC + + two modes, one is the other one is the Release Build Debug Build. the difference between them is that, Release Build does not debug the source code, without regard to the diagnosis of MFC macros, using MFC Release database, compiled ten pairs of applications to optimize the speed, while the Debug Build, by contrast, it allows the source code for debugging, you can define and use the diagnosis of MFC macros, using MFC Debug library, not optimized for speed. so we should be in Debug mode, application development, In Release mode, and then publish the application. In our project there will be a folder Debug folder and a Release folder and intermediate output files were stored files.
diagnostic macro is to compile a program enabling the state tests tools, such as used on the two TRACE macro in the Debug window, you can get diagnostic information you need without having to set the dialog box like the method, at the time of Release of this information is automatically filtered out.
actually debugging an application is a very challenging job, and I believe we have a similar experience, recruited from the Internet or books for a code or source code, that point when we knocked them into the compilation after Deleloper Studio when all of a sudden there numerous errors and warnings, (some of the books of the source code is wrong) that needs patience and experience with VC + + debugging tools available, such as diagnostic macros, set breakpoints, single stepping, etc. We will save a lot of effort. As for the topic should really compile a lot to say, but because of Raytheon's own lack of experience can only speak on the book for a summary, large ...

Agency Association will be reported to you,
Agency Association to remind the enterprises to strengthen self-discipline, flexible way home buyers eligible for new guise, the industry said no winners
PRC Beijing Feb. 23 (Xinhua reporter Wang Xue Zhang Qi practice) does not meet the 5 years to pay social security conditions, then buy it? Agency work to buy a residence permit it? Recently, many people are concerned about the purchase of the policy problem, and press the surveys also show that part of the agency in order to contribute to business sales, customer promise that the argument is real to the enemy, a new guise. In response, Beijing Real Estate Agents Association 23, said the agency is currently looking for close attention to the behavior of policy loopholes, will report to government authorities, and called for companies to strengthen self-discipline. Strict implementation of current policy, by various means to purchase qualified alternative did not see success stories.
stores: can vouch for the purchase of individual companies eligible to
Recently, there is a saying on the network - to spend thousands of dollars to change the tax payment certificate, whereby reporters visited a number of housing agencies and found that the agency paid proof of the different attitudes of agents.
journalists to buyers who visited one in the name of Hu Jia Lou, Chaoyang District, the housing agency, consulting agency paid proof hearing, the clerk made it clear that the company can not do, but said said: ) company can do. .
reporter followed another into the adjacent housing agency, a press room, only one person consulting housing information, sales are on the phone or chat. When a reporter asked: pay, absolutely no problem. Asked the specific details, the clerk said that the cost of agency only a few thousand dollars, to us.
However, a large chain of a housing agency, said agency staff members clearly prove that buy a house until after the policy change.
, the reporter in the agency consulted by phone online shop related issues, intermediaries are relatively cautious, but both companies to disclose the relevant personnel Downstream Strategies Well, I did not do too before, the new approaches must be thought out, the only question.
industry: work eligibility is limited to
the current spread of a variety of industries in the intermediary for the purchase of the New Deal's necessary loss.
Centaline three deputy general manager of marketing, said Gong Ping, in theory, pay the social security or income tax has its possibilities, some companies may contract in the first post-New Deal, the use of such strategy, from the reality of the situation, a considerable number of companies may pay the past on the social security of employees is not standardized, based on the actual life of the contract or employee will pay the associated costs up, but also a grain of truth, brokerage companies prompt customers to pay, but should not participate in or forged.
She pointed out that the implementation of policies due to the current time is shorter, the New Deal contract signed after the submission of network audit is still expected to wait several days to have the Government for approval a result, some policies to deal with the folklore of the feasibility or allowed, still in the theoretical stage, which includes the economic costs and risks are great, thousands, tens of thousands are likely, buyers who can not believe in the words of intermediaries.
Albert I love my family, group vice president 胡景晖 that spread from the current point of view means more work, income, residence of the forged work is a basic feasible, social security and other means of information network in back, the government administration vulnerabilities can be identified, the so-called flexible approach may be, but at least so far unable to prove its effectiveness or permission, and implementation details of the changes in the future there is the possibility that house prices have gradually stabilized, if qualified enough, wait and so may be more sensible,
Association: The report on the behavior of intermediaries loopholes
Agents Association Vice President of Beijing were Chu week said it had learned that the purchase of policies for He believes that previous policy control point of view from the past, developers, operating pressure in the intermediary industry, there are some instincts,
strength and determination but the government point of view, he considered that any loopholes in the current round of regulation will be quick to make up for such acts, the intermediary industry associations will report to government departments, and promote self-regulation in the industry.
It is understood that, due to the purchase of policies, each agency reporters in the stores during the investigation, were found to significantly affect the business issues, individual agency is also clear that the recent adjustment of stores and reduce the number. ZHOU Zong-Chu said the new deal even though the short term the market will have some impact, but also increased the exchange of building opportunities for trading and leasing business, the industry association will actively guide each company in the future, and employees for business innovation, seeking new growth point benign development.

Refuting
Gold model 50% of miners as the one sent down wages, each worker income of 50,000 a year, they get a million to rent an apartment, the remaining forty to get married, have children, married and the hands of another five miners million, can make investments. because of the hands of the workers money, to be settled, so there needs a house. So mine used his money to build a house, leased workers, or sold to workers. workers eat and drink, so to open the hotel, the workers and his money and then get it back. Kaifan Guan also employed other workers, so the wife has employment opportunities for workers, but also get paid. a family of consumer demand is even greater. In this way, a few years later , in the parts of the 100 families. children to school, with educational needs, so some people to run schools, workers have to date, to consumption, to do something else, so have a movie theater, with shops, so that After 50 years in the past, when this place a mine about to be dug when the light here has become a thriving city of around 10 million people.
while the second is this: Suppose also found a gold mine, The same was to invest in mining, also employed 100 workers, the same profit 10 million per year, but the mine owners to pay 10% of them sent down 10,000 a year per worker. The money is only enough that they barely fill the stomach, no money rent an apartment, a wife no money, only to live shack. miners earn a year of 900 million, but look at her eyes are poor, nothing in the local re-investment would be demand. So he put the money to foreign countries as simply not in the local security, he built several luxury villas, several workers employed as bodyguards, the workers have no future, in addition to hard work ends meet, there is no other demand. The only possible thing is to find ways to Me and a wife to cheat , birth to a beautiful daughter, might be able to marry mine wife. After 50 years go, this place apart from luxury villas, still no other industry. until the mines dug over, miners with large sums of money away, workers are either in exile or men for stealing, woman into prostitution. Frankly speaking, that is, can not eat can not wear gold, dug up after you sold the goods in exchange for food and clothing? let alone those you reinvest the hotel made of construction materials to build a house? sell workers? people to take a total of only to 500 million salary, how can 10 million from them in return? sold to a person other than gold? mm You're not discussing the talk about .
mine finished his wages after the 500 million left on hand. According to on. tentatively mine owners also run the farm operator, building materials, plants, etc., to achieve self-sufficiency in raw materials, do not exchange with the outside world. so good, if miners are cast into this 500 million (the amount spent tentatively ignore the miners themselves, because you can assume that he room and board to open the restaurant in their own), to build a house, building hotels. workers are to buy or rent this house, eat in the restaurants, the money is paid to get their wages.
no matter how many workers , an amount is determined. that is, add up all the money in the hands of workers, just 500 million more, no less. So that is, mine owners of these houses and restaurants, and finally can only get 500 million turnover . a little more as well. (unless people from outside come here to spend. but here are a consumer should not be considered an outsider to the issue here, because the discussion is That is, mine had only 500 million on hand. This, as all 500 million of investment costs, turned into houses and restaurants and the like. After spending round workers, miners, million and only few mm not much, because not all of the wages of all workers see themselves spend. In other words, miners can be foreseen: the year of investment in gold is absolutely stable than compensation is not earned.
but ?
then some people may say, need to invest 500 million the first year of construction of hotels and housing, but the second year, no longer cast was set. So perhaps the long term, or feasible thing.
then we Read on. to the second year can be divided into two cases. The first is a mine that they have completed the sold out. The second is the miners that case, the miners outsiders can not make money, then left with the object of making money out of workers. As mentioned above, the former miners in the first year to their 500 million on hand are used to do all kinds of gold provided outside the consumer's enterprises, and then the number will not pay more than 4.99 million yuan. That means, this year he's spending by the workers paying the money recovered less than 4.99 million yuan, is likely to be 4.98 million yuan mm because, as mentioned above, not all will appear spend all the wages of workers.
then continue doing this, declining wages, and earn back part of the mine owners are declining. So, about 500 years after the miners must go bankrupt. Of course, the miners will not wait for 500 years. If the normal brain is estimated that less than three years, then immediately quit the. So the first case the operation is not feasible.
talk about the second case. workers continue to dry gold ore, gold continues to sell outsiders. So the second year of gold income is 10 million yuan, of which 500 million for wages. then left with 4.99 million the first year, mine owners will have 9.99 million on hand . Meanwhile, wages for workers other than gold consumed enterprises mm but not all consumed, consuming only 499 million (and as the first year). then mine 4.99 million yuan. This mine has been on hand for a total of 999 +499 = 14.98 million yuan. Now the question becomes: which 14.98 million yuan I what? continue to invest in enterprises? but also wages Chengsi 500 million, and also are you sent to them. to do the business out later if you do not provide consumer, that is, up to 500 million this did not add value. that investment in what is the use? just a waste of money.
we are embarrassed to see that, when the the same dilemma: the money is nowhere to invest. The ; of logic, the only option is exactly the same as mine. other workers, so the wife has employment opportunities for workers, but also get paid. a family of consumer demand is even greater. In this way, a few years later, in the parts of the 100 families. children to school, with education demand, so some people come to schools, workers have to date, to consumption, to do something else, so have a movie theater, with the store. will change the fact that: 1, the wages of all employees and workers, mine owners are issued; 2, the mine owners of businesses outside the gold if not for the crowd, no matter how that operation, most can only be These he sent to the wages only; 3, because not all employees and workers spend all the wages, so the miners no matter how well run, can not be issued to pay all 4 more people employed, employees and workers were kept out of the wages but not the more consumption, miners can not be more. Why think mine would be so stupid?
probably argue that in fact this analogy is that the national miners, capitalists just to maximize their own interests, but the country could still do that sort of wealth with the people of wages only. for his own, the investment did not bring any added value (or rather, the increase in value can not be achieved). that such a mining area (countries) to grow? This is not the worst. the worst mine workers is something consumer spending tired of miners, with their outbound travel to save money, and to spend the money to go beyond the mining area, cheap outsiders. that mine was really tears it. < br> so visible, Politics and economics, so some common sense feeling down. In fact, do not look this eloquent argument for a long time, if the Marxist political economy is a few words to explain things: a simple distinction between reproduction and expanded reproduction. a system of surplus value generated must be transformed into the capital of foreign exchange, otherwise overproduction. In other words, is not sold out will not be able to expand production. This is what Marx said capitalism inherently expansionary reason. Now almost Marxist Economics into mice on the streets, the results have
while the second is this: Suppose also found a gold mine, The same was to invest in mining, also employed 100 workers, the same profit 10 million per year, but the mine owners to pay 10% of them sent down 10,000 a year per worker. The money is only enough that they barely fill the stomach, no money rent an apartment, a wife no money, only to live shack. miners earn a year of 900 million, but look at her eyes are poor, nothing in the local re-investment would be demand. So he put the money to foreign countries as simply not in the local security, he built several luxury villas, several workers employed as bodyguards, the workers have no future, in addition to hard work ends meet, there is no other demand. The only possible thing is to find ways to Me and a wife to cheat , birth to a beautiful daughter, might be able to marry mine wife. After 50 years go, this place apart from luxury villas, still no other industry. until the mines dug over, miners with large sums of money away, workers are either in exile or men for stealing, woman into prostitution. Frankly speaking, that is, can not eat can not wear gold, dug up after you sold the goods in exchange for food and clothing? let alone those you reinvest the hotel made of construction materials to build a house? sell workers? people to take a total of only to 500 million salary, how can 10 million from them in return? sold to a person other than gold? mm You're not discussing the talk about .
mine finished his wages after the 500 million left on hand. According to on. tentatively mine owners also run the farm operator, building materials, plants, etc., to achieve self-sufficiency in raw materials, do not exchange with the outside world. so good, if miners are cast into this 500 million (the amount spent tentatively ignore the miners themselves, because you can assume that he room and board to open the restaurant in their own), to build a house, building hotels. workers are to buy or rent this house, eat in the restaurants, the money is paid to get their wages.
no matter how many workers , an amount is determined. that is, add up all the money in the hands of workers, just 500 million more, no less. So that is, mine owners of these houses and restaurants, and finally can only get 500 million turnover . a little more as well. (unless people from outside come here to spend. but here are a consumer should not be considered an outsider to the issue here, because the discussion is That is, mine had only 500 million on hand. This, as all 500 million of investment costs, turned into houses and restaurants and the like. After spending round workers, miners, million and only few mm not much, because not all of the wages of all workers see themselves spend. In other words, miners can be foreseen: the year of investment in gold is absolutely stable than compensation is not earned.
but ?
then some people may say, need to invest 500 million the first year of construction of hotels and housing, but the second year, no longer cast was set. So perhaps the long term, or feasible thing.
then we Read on. to the second year can be divided into two cases. The first is a mine that they have completed the sold out. The second is the miners that case, the miners outsiders can not make money, then left with the object of making money out of workers. As mentioned above, the former miners in the first year to their 500 million on hand are used to do all kinds of gold provided outside the consumer's enterprises, and then the number will not pay more than 4.99 million yuan. That means, this year he's spending by the workers paying the money recovered less than 4.99 million yuan, is likely to be 4.98 million yuan mm because, as mentioned above, not all will appear spend all the wages of workers.
then continue doing this, declining wages, and earn back part of the mine owners are declining. So, about 500 years after the miners must go bankrupt. Of course, the miners will not wait for 500 years. If the normal brain is estimated that less than three years, then immediately quit the. So the first case the operation is not feasible.
talk about the second case. workers continue to dry gold ore, gold continues to sell outsiders. So the second year of gold income is 10 million yuan, of which 500 million for wages. then left with 4.99 million the first year, mine owners will have 9.99 million on hand . Meanwhile, wages for workers other than gold consumed enterprises mm but not all consumed, consuming only 499 million (and as the first year). then mine 4.99 million yuan. This mine has been on hand for a total of 999 +499 = 14.98 million yuan. Now the question becomes: which 14.98 million yuan I what? continue to invest in enterprises? but also wages Chengsi 500 million, and also are you sent to them. to do the business out later if you do not provide consumer, that is, up to 500 million this did not add value. that investment in what is the use? just a waste of money.
