Topic: Track Active Drawing

[UWPMVG]

I will keep looking for a solution for this problem. If any of you comes up with something, let me know.

I found the solution with help from Kean Walmsley.

The following code works:

Code: [Select]

AddHandler AcApp.DocumentManager.DocumentActivated, AddressOf Me.DocumentManager_DocumentActivated

...

Private Sub DocumentManager_DocumentActivated(ByVal sender As Object, ByVal e As DocumentCollectionEventArgs)
        If Application.DocumentManager.MdiActiveDocument IsNot Nothing Then
            MsgBox("Active drawing has changed!")
        End If
End Sub
