When to Initialize CWnd Objects

Note

The Microsoft Foundation Classes (MFC) library continues to be supported. However, we're no longer adding features or updating the documentation.

You cannot create your own child windows or call any Windows API functions in the constructor of a CWnd-derived object. This is because the HWND for the CWnd object has not been created yet. Most Windows-specific initialization, such as adding child windows, must be done in an OnCreate message handler.
