MFC编程

写道

The Microsoft Foundation Class (MFC) Library provides an object-oriented wrapper over much of the Win32 and COM APIs. Although it can be used to create very simple desktop applications, it is most useful when you need to develop more complex user interfaces with multiple controls. You can use MFC to create applications with Office-style user interfaces. For documentation on the Windows platform itself, see Windows documentation. For information on building Windows applications in C++ without MFC, see Build desktop Windows apps using the Win32 API.

 

_tWinMain

参考MFC\SRC\APPMODUL.CPP代码。在_tWinMain函数中就直接调用了AfxWinMain函数。

extern "C" int WINAPI
_tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
	LPTSTR lpCmdLine, int nCmdShow)
{
	// call shared/exported WinMain
	return AfxWinMain(hInstance, hPrevInstance, lpCmdLine, nCmdShow);
}

AfxWinMain

参考MFC\SRC\WINMAIN.CPP代码。

int AFXAPI AfxWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
	LPTSTR lpCmdLine, int nCmdShow)
{
	ASSERT(hPrevInstance == NULL);

	int nReturnCode = -1;
	CWinThread* pThread = AfxGetThread();
	CWinApp* pApp = AfxGetApp();

	// AFX internal initialization
	if (!AfxWinInit(hInstance, hPrevInstance, lpCmdLine, nCmdShow))
		goto InitFailure;

	// App global initializations (rare)
	if (pApp != NULL && !pApp->InitApplication())
		goto InitFailure;

	// Perform specific initializations
	if (!pThread->InitInstance())
	{
		if (pThread->m_pMainWnd != NULL)
		{
			TRACE0("Warning: Destroying non-NULL m_pMainWnd\n");
			pThread->m_pMainWnd->DestroyWindow();
		}
		nReturnCode = pThread->ExitInstance();
		goto InitFailure;
	}
	nReturnCode = pThread->Run();

InitFailure:
#ifdef _DEBUG
	// Check for missing AfxLockTempMap calls
	if (AfxGetModuleThreadState()->m_nTempMapLock != 0)
	{
		TRACE1("Warning: Temp map lock count non-zero (%ld).\n",
			AfxGetModuleThreadState()->m_nTempMapLock);
	}
	AfxLockTempMaps();
	AfxUnlockTempMaps(-1);
#endif

	AfxWinTerm();
	return nReturnCode;
}
