OpenClipboard MFC

Hello

I'm doing a application using MFC.

My problem is when I call OpenClipboard the program crashes because the member m_hWnd of class CWnd is not valid.

I tried gave a HWND handle for it , because you have direct access to that member, but dosen't work either, i gave the HWND of my child window, the crash stop but my child window closes.


Anyone knows something?

Thanks =)

Why is the m_hWnd member not valid? Does your CWnd class represent a created window?

You can always just open the clipboard with the win32 function. Pass NULL as the parameter, so the clipboard is associated with your current task.

Hi,

I dont know why is invalid =(

The strange thing is that in another function of the same class dont crash, the only difference is that this class is a afx msg function.

I cant use the standard GetForegroundWindow, the compiler dont allow me.

Thanks for attention =)
