AfxOleInit 

Initializes OLE support for the application.


BOOL AFXAPI AfxOleInit( );

Nonzero if successful; 0 if initialization fails, possibly because incorrect versions of the OLE system DLLs are installed.

Call this function to initialize the OLE support for an MFC application. When this function is called, the following actions occur:

  • Initializes the COM library on the current apartment of the calling application. For more information, see OleInitialize.

  • Creates a message filter object, implementing the IMessageFilter interface. This message filter can be accessed with a call to AfxOleGetMessageFilter.

NoteNote

If AfxOleInit is called from an MFC DLL, the call will fail. The failure occurs because the function assumes that, if it is called from a DLL, the OLE system was previously initialized by the calling application.

NoteNote

MFC applications must be initialized as single threaded apartment (STA). If you call CoInitializeEx in your InitInstance override, specify COINIT_APARTMENTTHREADED (rather than COINIT_MULTITHREADED). For more information, see PRB: MFC Application Stops Responding When You Initialize the Application as a Multithreaded Apartment (828643) at http://support.microsoft.com/default.aspx?scid=kb;en-us;828643.
