How do I add a textbox control to a frame object (declared as OLEObject) in
vba code behind a worksheet?

For example, I have tried the following that doesn't work...

Dim objFrame As OleObject
Set objFrame = ActiveSheet.OLEObjects.Add(ClassType:="Forms.Frame .1")
With objFrame
.Object.Controls.Add ClassType:="Forms.Textbox.1"
End With
