The framework calls this member function for all top-level windows when the Desktop Window Manager (DWM) composition is enabled or disabled.

afx_msg void OnCompositionChanged();

This method receives the WM_DWMCOMPOSITIONCHANGED notification, which is described in the Windows SDK.


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.
