The framework calls this member function when the CWnd object is minimized and the user requests that the CWnd be restored to its preminimized size and position.

afx_msg BOOL OnQueryOpen( );

Return Value

Nonzero if the icon can be opened, or 0 to prevent the icon from being opened.


While in OnQueryOpen, CWnd should not perform any action that would cause an activation or focus change (for example, creating a dialog box).
