I use VS2012, run the MFC Windows programming examples, code like books, the code is as follows:
Hello. H file:

 class CMyApp: public CWinApp//define a application class 
{
Public: 
Virtual bool InitInstance (); 
}; 
Class CMainWindow: public CFrameWnd//define an application window class 
{
Public: 
CMainWindow (); 
Protected: 
Afx_msg void OnPaint (); 
DECLARE_MESSAGE_MAP () 
}; 

Hello. CPP file:

 # include & lt; Afxwin. H> 
# include "Hello. H" 
CMyApp myApp.//instantiate an application object 
BOOL CMyApp: : InitInstance () 
{
M_pMainWnd=new CMainWindow; 
M_pMainWnd - & gt; ShowWindow (m_nCmdShow); 
M_pMainWnd - & gt; UpdateWindow (); 
Return TRUE; 
} 

BEGIN_MESSAGE_MAP (CMainWindow CFrameWnd) 
ON_WM_PAINT () 
END_MESSAGE_MAP () 

CMainWindow: : CMainWindow () 
{
Create (NULL, _T (" The Hello App!" )); 
} 

Void CMainWindow: : OnPaint () 
{
CPaintDC dc (this); 
CRect the rect. 
GetClientRect (& amp; The rect); 

Dc. DrawText (_T (" Hello, MFC "), 1, & amp; The rect, 
DT_SINGLELINE | DT_CENTER | DT_VCENTER); 
} 

Below is the error message:
Error 1 error C1189: # error: Building MFC application with/MD [d] (CRT DLL version) requires the MFC Shared DLL version. Both Please # define _AFXDLL or do not use/MD [d] c: \ program files \ Microsoft visual studio (x86) vc 11.0 \ \ atlmfc \ include \ afx 24 h

How do these errors, online etc.! Thank you friends!

CodePudding user response:

Bool and bool is not the same, want case-sensitive

CodePudding user response:

BOOL CMyApp: : InitInstance ()
Virtual bool InitInstance ();

BOOL and BOOL is not a type,

CodePudding user response:

refer to the second floor schlafenhamster response:

BOOL CMyApp: : InitInstance ()
Virtual bool InitInstance ();

BOOL and BOOL is not a type,

why manually enter example code, to set up using static or dynamic library, cannot use Windows standard library, also want to choose a multi-byte character set, why should specify the entry point, and take the example of don't however, such a set, can be used in the actual project?

CodePudding user response:

reference 1st floor zgl7903 response:

bool and bool is different, be case-sensitive

I run this example, I want to ask, CWinApp with CWinAppEx use anything, why I can't change the CWinApp to CWinAppEx use, thank you!

Did you all get rid of? This project search CWinApp modified into CWinAppEx try ~
