CWnd::OnPaletteIsChanging
Visual Studio 2010
The framework calls this member function to inform applications that an application is going to realize its logical palette.
afx_msg void OnPaletteIsChanging( CWnd* pRealizeWnd );
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.
