Application.IsInScope Property (Visio)
Determines whether a call to an event handler is between an EnterScope event and an ExitScope event for a scope. Read-only.
expression A variable that represents an Application object.
|nCmdID||Required||Long||The scope ID.|
Constants representing scope IDs are prefixed with visCmd and are declared by the Visio type library. You can also use an ID returned by the BeginUndoScope method.
You could use this property in a CellChanged event handler to determine whether a cell change was the result of a particular operation.
This example shows how to use the IsInScope property to determine whether a call to a procedure that handles the CellChanged event is in a particular scope?that is, whether the call occurs between the EnterScope and ExitScope events for that scope.
