Re: VC++ 2005 problem creating an ActiveX in a secondary Thread

Hi Daniele,

Further discussion with other MFC experts confirms my suspicion.

Yes. It is a mistake to pass a pointer of a CWnd-derived class across a
thread boundary. Any calls across that boundary that attempt to use the
thread-local storage that MFC maintains for window objects will fail. This
is not specific to ActiveX - it is true for all window class objects in MFC.

So, why do you want to place CFINSAxEFS in the second thread?

Best regards,
Jeffrey Tan
