CMFCVisualManager::OnUpdateSystemColors
The framework calls this function when it changes the system colors.
virtual void OnUpdateSystemColors();
Remarks
The framework calls this method as a part of processing the WM_SYSCOLORCHANGE message. The default implementation does nothing. Override this method in a derived visual manager if you want to execute custom code when the colors change in your application.
