Re: Difference btw 'this' pointer in EXE and ActiveX

Hi,

I would like to know if there is a difference 'this' pointer in EXE
compared to ActiveX. I am developing a custom media player for my
application. I was able to develop the media player as a dialog based
EXE now I want to develop it as an ActiveX. I am using a function to
show the video stream the function prototype is like this
DWORD WINAPI chtStreamOpen(
               HANDLE* phStream, //[OUT]
DWORD dwStreamType, //[IN]
HWND hWnd, //[IN], Video display window handle
PCHTSTREAMINFO pStreamInfo, //[IN/OUT] a structure having stream
information
PCHTCALLBACK pCallback, //[IN] call back function.
void* pContext, //[IN] where pContext is 'this' pointer, the
callback function context
DWORD dwVgDevType //[IN]
);
The thing is this works fine in the EXE but when i use it in ActiveX
its failing. I strongly believe its due to the pContext. Can anyone
help me out of this?

Thanks
