BUG: Arrows to Scroll Tabs in TabStrip Control Not Shown

• Standard, Professional, and Enterprise Editions of Microsoft Visual Basic, 32-bit only, version 4.0

SYMPTOMS

The TabStrip control provides arrows to scroll Tabs inside the control if there are more Tabs than can be displayed in the available width of the control. However, these arrows only appear on the Tabstrip control after certain properties of the control have been used in code.

WORKAROUND

To cause the arrows to appear, refer to a property such as the Caption of the Tab in the Load event of the Form on which the TabStrip control is contained. For example, placing the following code in the Load event causes the spin controls to correctly appear on the Tabs:

  Private Sub Form_Load()
     Dim TmpStr As String
     Me.Show
     DoEvents
     TmpStr = TabStrip1.Tabs(1).Caption
     TabStrip1.Tabs(1).Caption = TmpStr
   End Sub

STATUS

Microsoft has confirmed this to be an issue in the Microsoft products listed at the beginning of this article. Microsoft is researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
