Place a container for each RTF box on each Tab of the SSTab control, i.e. a Picturebox, then use code similar to the following:
VB Code:
  1. Private Sub Form_Load()
  2.     Dim lCount As Long
  3.    
  4.     For lCount = 0 To 6
  5.         If lCount > 0 Then Load rtfRTFs(lCount)
  6.         With rtfRTFs(lCount)
  7.             Set .Container = picContainers(lCount)
  8.             With picContainers(lCount)
  9.                 .Move 12, SSTab1.TabHeight + 12, SSTab1.Width - 24, SSTab1.Height - SSTab1.TabHeight - 24
  10.                 .BorderStyle = vbBSNone
  11.             End With
  12.             .Move 0, 0, picContainers(lCount).ScaleWidth, picContainers(lCount).ScaleHeight
  13.             .Text = "Tab" & lCount + 1
  14.             .Visible = True
  15.         End With
  16.     Next
  17. End Sub
