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.

RESOLUTION

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 a bug in the Microsoft products listed at the beginning of this article. This bug has been fixed in Visual Basic 5.0.

MORE INFORMATION

Steps To Reproduce the Problem

Start a new project in Visual Basic. Form1 is created by default.
Place a TabStrip control on Form1.
Invoke the Custom property page for the TabStrip control by choosing the ellipsis (...) adjacent to the Custom property. In the Tabs tab of the property pages, press the Insert tab button 20 times.
Press the F5 key to run the project. Note that there are no spin buttons to move to different Tabs.

To correct the problem above, place the code in the WORKAROUND section into the Form_Load event of Form1. Then the spin buttons correctly show on the TabStrip control when the form appears.
