I'm wondering if there is a notify event for an active configuration change in the open document?

I have an add-in I'm working on that creates a new taskpane view that has some buttons and a

listbox on it. I populate the listbox with all of the configuration names whenever the active document

changes with:

Private Function swApp_ActiveModelDocChangeNotify() As Integer Handles swApp.ActiveModelDocChangeNotify

Thank You Ivana Kolin!

I then set the selected item of the listbox as whatever the active configuration is. But I don't know if there is a

similar event for an active configuration change. Any help would be appreciated. Thanks.
