Hello,

I have a class derived from CXTPTaskDialog.
When I instanciate it, its hWnd is NULL, so I can not PostMessage() to it (Vista, Win7).

Do you know how I can get a valid hWnd ??

Thanks in advance

I have found that CXTPTaskDialog provides the member m_hwndTaskDialog which is not NULL. I can PostMessage() to it under XP but it still doesn't work on Win7.
