I've figured out how to add text boxes, labels, combo boxes etc.

I've spent the last two hours trying to find here and in google, where to
get a list of properties for these objects and the proper drill down to
access them.

I manually added a label, then right clicked and accessed properties. I can
see see the properties, however they don't seem to be logically accessible.

I can access the "Caption" property but not the "font" property. See below.

Set shp =
app.ActiveWindow.Selection.SlideRange.Shapes.AddOLEObject(Left:=dblLeft,
Top:=dbltop, Width:=dblWidth, Height:=dblheight, ClassName:="Forms.Label.1",
Link:=msoFalse)

  With shp.OLEFormat.Object
    .Caption = strtext
    .Font = "Arial"
  End With

NOTE: the caption property which is on the same level as Font property
works. It's accessible in the code above. What on earth is going on here and
I guess the real question is where do I find the heirarchy of the properties
so I can access them and change them as needed?

Thanks
