Catching MFC exception

[Fabian Cenedese]

Hi

I found one of the wrong behaviours though I don't know where to solve it. 
For creating an ocx one can give a window title. I gave a "" to the 
CreateControl function. But this poses a problem to MFC, it's only prepared 
for valid strings or NULL pointers. That's why it generates the exception:

void AFXAPI AfxThrowOleException(SCODE sc){
#ifdef _DEBUG
    TRACE1("Warning: constructing COleException, scode = %s.\n",
    	AfxGetFullScodeString(sc));
#endif
    COleException* pException = new COleException;
    pException->m_sc = sc;
    THROW(pException);
}

In Windows this is caught by another function in MFC and doesn't do any harm:

BOOL AFX_CDECL COleControlSite::SafeSetProperty(DISPID dwDispID, VARTYPE 
vtProp, ...) {
    va_list argList;    // really only one arg, but...
    va_start(argList, vtProp);
    BOOL bSuccess;
    TRY {
    	SetPropertyV(dwDispID, vtProp, argList);
    	bSuccess = TRUE;
    } CATCH_ALL(e) {
    	DELETE_EXCEPTION(e);
    	bSuccess = FALSE;
    } END_CATCH_ALL
    va_end(argList);
    return bSuccess;
}

Now it seems that the exception handling inside (or wherever) the MFC.dll 
doesn't work if running in Wine or the MFC exceptions are different and the 
exception comes right through. I can overcome this problem by giving a 
valid window title but that solves it only for me. I have no idea how and 
if this can be solved but maybe this description gives a hint to a 
programmer with more insight.

Thanks

This may be an msvcrt issue. Does it work if you use native msvcrt?
If so, if you mail me a .exe showing the problem I'll look into it.
