After much fumbling and bumbling, I finally figured out how to make TabStrips work in the VB 6.0 environment. You have to pass the Index Property through the TabStrip SelectedItem Method, as in:

Select Case TabStrip1.SelectedItem.Index

So the code would look like:

Private Sub TabStrip1_Click()

Select Case TabStrip1.SelectedItem.Index

Case 1
'Your code here...'

Case 2
'Your code here...'

Case 3
'Your code here...'

AND SO ON...

End Select

End Sub

That's it, enjoy...
