The framework calls this member function prior to the WM_CREATE message when the CWnd object is first created.
afx_msg BOOL OnNcCreate( LPCREATESTRUCT lpCreateStruct );
Points to the CREATESTRUCT data structure for CWnd.
Nonzero if the nonclient area is created. It is 0 if an error occurs; the Create function will return failure in this case.
This member function is called by the framework to allow your application to handle a Windows message. The parameters passed to your function reflect the parameters received by the framework when the message was received. If you call the base-class implementation of this function, that implementation will use the parameters originally passed with the message and not the parameters you supply to the function.
