The IOleControl interface provides the features for supporting keyboard mnemonics (GetControlInfo, OnMnemonic), ambient properties (OnAmbientPropertyChange), and events (FreezeEvents) in control objects.
Implement this interface for a control object to communicate with the control’s container, for example, when managing keyboard activity or obtaining the container’s ambient properties.
A control container uses this interface to work with keyboard mnemonics, ambient properties, and events of a contained control object.
