returning and accessing an object via com

Hi,
at first a big compliment for this great article and the translation to c#.
at second, my question:

I'm developing a chartcomponent in c# which should be accessed from vb6 via com. I have got a method which is called accBar. It adds a Bar to the diagramm and should return the barObject. The problem is, every time I try to handle the returning value vb6 tells me of a type missmatch error.
my code, perhaps it helps:


Private Sub Command2_Click()Dim gb2 As GanttControl.GanttBarNgb2 = GanttControl1.addBar("lala", 35, 56, "lalala")End Sub


Is it possible to return the interface from c# or should I return the object itself?

I hope someone can help me with a hint, I'm looking for a solution now, for 3 days .
