Adding MFC Support to an ATL EXE Project
Add the following #include directives to StdAfx.h prior to including Atlbase.h:
#include <afxwin.h> // MFC core and standard components
#include <afxext.h> // MFC extensions
#include <afxdisp.h> // MFC Automation extensions
Change project settings to use MFC. From the Project Settings dialog box, click the General tab, and change the setting in the "Microsoft Foundation Classes" list box to MFC.
Add a CWinApp derived class and declare a global variable of that type as follows:
class CMyApp : public CWinApp
{
public:
virtual BOOL InitInstance();
virtual int ExitInstance();
protected:
BOOL m_bRun;
};
Replace the _tWinMain function with the following InitInstance and ExitInstance code:
BOOL CMyApp::InitInstance()
{
// Initialize OLE libraries.
if (!AfxOleInit())
{
AfxMessageBox(_T("OLE Initialization Failed!"));
return FALSE;
}
// Check command line arguments.
TCHAR szTokens[] = _T("-/");
m_bRun = TRUE;
LPCTSTR lpszToken = FindOneOf(m_lpCmdLine, szTokens);
while (lpszToken != NULL)
{
// Register ATL and MFC class factories.
if (lstrcmpi(lpszToken, _T("Embedding"))==0 ||
lstrcmpi(lpszToken, _T("Automation"))==0)
{
AfxOleSetUserCtrl(FALSE);
break;
}
// Unregister servers.
// There is no unregistration code for MFC
// servers. Refer to <LINK TYPE="ARTICLE" VALUE="Q186212">Q186212</LINK> "HOWTO: Unregister MFC
// Automation Servers" for adding unregistration
// code.
else if (lstrcmpi(lpszToken, _T("UnregServer"))==0)
{
VERIFY(SUCCEEDED(_Module.UpdateRegistryFromResource(IDR_ServerS2B, FALSE)));
VERIFY(SUCCEEDED(_Module.UnregisterServer(TRUE)));
m_bRun = FALSE;
break;
}
// Register ATL and MFC objects in the registry.
else if (lstrcmpi(lpszToken, _T("RegServer"))==0)
{
VERIFY(SUCCEEDED(_Module.UpdateRegistryFromResource(IDR_ServerS2B, TRUE)));
VERIFY(SUCCEEDED(_Module.RegisterServer(TRUE)));
COleObjectFactory::UpdateRegistryAll();
m_bRun = FALSE;
break;
}
lpszToken = FindOneOf(lpszToken, szTokens);
}
if (m_bRun)
{
// Comment out the next line if not using VC 6-generated
// code.
_Module.StartMonitor();
VERIFY(SUCCEEDED(_Module.RegisterClassObjects(CLSCTX_LOCAL_SERVER, REGCLS_MULTIPLEUSE)));
VERIFY(COleObjectFactory::RegisterAll());
// To run the EXE standalone, you need to create a window
// and assign the CWnd* to m_pMainWnd.
LPCTSTR szClass = AfxRegisterWndClass(NULL);
m_pMainWnd = new CWnd;
m_pMainWnd->CreateEx(0, szClass, _T("SomeName"), 0, CRect(0, 0, 0, 0), NULL, 1234);
}
return TRUE;
}
int CMyApp::ExitInstance()
{
// MFC's class factories registration is
// automatically revoked by MFC itself.
if (m_bRun)
{
_Module.RevokeClassObjects();
Sleep(dwPause); //wait for any threads to finish
}
_Module.Term();
return 0;
}
For Unicode builds, make sure the entry point is set to wWinMainCRTStartup in the Output category of the Link field in the Project Settings dialog box. For additional information, please see the following article in the Microsoft Knowledge Base:
Q125750 PRB: Error LNK2001: '_WinMain@16': Unresolved External Symbol
Add the following line of code to the beginning of every member function of a COM interface, window procedure, and exported function:
AFX_MANAGE_STATE(AfxGetAppModuleState());
For more information on AFX_MANAGE_STATE, consult the VC++ online documentation.
