I have created an addin that creates on CommandBar with one button control
to run it.

In a code module I have written the creation and settins methods which are
call by code inside:
ThisWorkbook Sub Workbook_Open()

When I wrote the setting for the toolbar, I included position setting

With TBar
           .Name = CBarName
           .Top = 0
           .Left = 0
           .Visible = True
End With

which creates a floating toolbar in the top left.

So I tried NOT using the . top and .left and instead using

   .position = msoBarTop

But that just centers the toolbar on screen.

How can I dock a custom toolbar into Excel's already present area up top.
What is that area called? and How do I access it?
