Hi,

I'm working on a project, where the user clicks on a button, which I've
added to all Office applications, and an activex controller gets inserted to
the current document. This is the code for inserting the controller, in c#
and for powerpoint.

Microsoft.Office.Interop.PowerPoint.Shape shape =
application.ActiveWindow.Selection.SlideRange.Shapes.AddOLEObject(120, 120,
320, 240, "TESTX.TestXCtrl.1", "", MsoTriState.msoFalse, null, 0, "Test",
MsoTriState.msoFalse);

Although this works like a charm, I need to get a handle to the actuall
activex controller, so I can set properties. In VB this is easy, I just do
this:

   Set ax =
ActiveWindow.Selection.SlideRange.Shapes.AddOLEObject(Left:=120, Top:=110,
Width:=480, Height:=320, ClassName:="TESTX.TestXCtrl.1", Link:=msoFalse)
   Set obj = ax.OLEFormat.Object
   
   obj.TestProperty = "Happy!"

And I know that I can get a handle to the object in c# the same way,
shape.OLEFormat.Object, but I dont know how to access the TestProperty
property of the controller, as I did with VB.

Any help is appreciated.

Regards
