A workaround would be, in Design View, to design each page like
you want it to look. You need to do this, because after the next
step, the tabs disappear in Design View as well as when the form
is run, and changing them in Design View is impossible. If you
make a mistake, you can always change the Style back to Tabs
temporarily.
Next, select the tabbed control (the entire control, not one of
the tabbed pages) and goto Properties - Format and set the Style
Property to "None."
Next, create your own command buttons, placed wherever you want
them.
In code behind the command buttons, use code like this
Private Sub Page1_Click()
Me.YourTabControlName = 0
End Sub
Private Sub Page2_Click()
Me.YourTabControlName = 1
End Sub
and so forth. Notice that the Values for pages is Zero-based, so
for Page1 you use 0, for Page2 you use 1, etc.
