Remarks

At any given time, the AnnAutomation can have a working AnnDesigner derived object as follows:

Designer Base Class	Notes
null (Nothing in Visual Basic)	(Design and Run user mode) no designer is currently active.
AnnDrawDesigner	(Design user mode) The AnnAutomation is currently drawing or about to draw a new object
AnnEditDesigner	(Design user mode) One or more objects are currently being edited or are about to be edited
AnnRunDesigner	(Run user mode) An object is currently being run or about to be run

This property allows you to hook into the current designer and change or monitor its status while it is running. For example, you can determine if CurrentDesigner is an AnnDrawDesigner derived class and subscribe to the Draw event and so forth.

Example
