try putting this in your template class.

virtual LRESULT WindowProc(UINT message,WPARAM wParam,LPARAM lParam)
{
switch (message)
{
case WM_PAINT:
  {
          CPaintDC dc(this);
  }
}

return CWnd::WindowProc(message, wParam, lParam);
}

I have a CWnd derived object that requires template parameters. But,
the MFC 8.0 macros obviously aren't made for dealing with templates.

Below is what I'm trying to do. Can anybody suggest the WinAPI
equivalent to the message map macros (or an alternative macro) that I
could use to accomplish what I want to get done?

Thanks,
PaulH
