virtual void OnShow( );
Remarks
Called by the framework to instruct the server application to display the OLE item in place. This function is typically called when the user of the container application creates an item or executes a verb, such as Edit, that requires the item to be shown. The default implementation attempts in-place activation. If this fails, the function calls the OnOpen member function to display the OLE item in a separate window.
Override this function if you want to perform special processing when an OLE item is shown.
