public void AnnAutomation_CurrentDesigner(AnnAutomation automation)  {     // subscribe to the DesignerChanged event of the automation     automation.CurrentDesignerChanged += new EventHandler(automation_CurrentDesignerChanged);  }  private void automation_CurrentDesignerChanged(object sender, EventArgs e)  {     // check if the current designer is a run designer     AnnAutomation automation = sender as AnnAutomation;     if (automation.CurrentDesigner != null && automation.CurrentDesigner is AnnRunDesigner)     {        AnnRunDesigner runDesigner = automation.CurrentDesigner as AnnRunDesigner;        // subscribe to this run designer Run event        runDesigner.Run += new EventHandler<AnnRunDesignerEventArgs>(runDesigner_Run);     }  }    private void runDesigner_Run(object sender, AnnRunDesignerEventArgs e)  {     if (e.OperationStatus == AnnDesignerOperationStatus.End)     {        string message = string.Format("Run object of type {0}, hyperlink = {1}", e.Object.GetType().Name, e.Object.Hyperlink);        MessageBox.Show(message);     }  }

(Read only) 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 AnnDrawDesigner.Draw event and so forth.
