CWinAppEx::EnableLoadWindowPlacement
Visual Studio 2012
Specifies whether the application will load the initial size and location of the main frame window from the registry.
void EnableLoadWindowPlacement( BOOL bEnable = TRUE );
By default, the size and location of the main frame is loaded from the registry together with other application settings. This occurs during CWinAppEx::LoadState. If you do not want to load the initial window placement from the registry, call this method with bEnable set to false.
