AfxOleUnlockControl
Visual Studio 2012
Unlocks the class factory of the specified control.
BOOL AFXAPI AfxOleUnlockControl( REFCLSID clsid ); BOOL AFXAPI AfxOleUnlockControl( LPCTSTR lpszProgID );
A control is locked with AfxOleLockControl, so that dynamically created data associated with the control remains in memory. This can significantly speed up display of the control because the control need not be created and destroyed every time it is displayed. When you are ready to destroy the control, call AfxOleUnlockControl.
