Can not add MFC support to Windows Application

[sawer]

Hi

We can add MFC support to console apps but hhy can't we add MFC support to Windows application?

I tried this:

#include <afx.h>
#include <afxwin.h>
#include <afxext.h> 

CWinApp theApp;


int WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)
{
	DWORD dwErrorCode;
	CString strErrorMessage;
	if(!(AfxWinInit(hInstance, hPrevInstance, (LPTSTR)lpCmdLine, nShowCmd)))
	{
		dwErrorCode = GetLastError();
		strErrorMessage.Format(L"Error is = %d", dwErrorCode);
		AfxMessageBox(strErrorMessage);

	}

	HANDLE hFile = CreateFile(L"\\\\.\\C:\\a.txt", GENERIC_WRITE, FILE_SHARE_WRITE, NULL, 
		CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL | FILE_FLAG_OVERLAPPED, NULL);
	
	CString cs;

	if(hFile == INVALID_HANDLE_VALUE)
	{
		dwErrorCode = GetLastError();
		strErrorMessage.Format(L"Error is = %d", dwErrorCode);
		AfxMessageBox(strErrorMessage);
	};

	CloseHandle(hFile);

	return 0;
}

It is compiled and executed but only CWinApp theApp; line is executed, before Winmain starts program exit. Why is it so?

Thanks...
