The framework calls this member when the current window is maximized, and the window is composed by the Desktop Window Manager (DWM).

afx_msg void OnWindowMaximizedChanged(
    BOOL bIsMaximized



[in] bIsMaximized

true if the current window is maximized, and false if it is not.

This method receives the WM_DWMWINDOWMAXIMIZEDCHANGE notification message, 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.
