The other day I found what I think is the easiest way to know who is calling a Visual Basic Dot Net method in your code at run time.

Sub Caller()
  Call Callee()
End Sub

Sub Callee()
  Dim trace As New StackTrace(True)
  Console.WriteLine(trace.GetFrame(1).GetMethod.Name )
  ' Writes "Caller" to the console window
End Sub

It strikes me as is incredibly similar to the way you do it in Java.
