Q151078: FIX: Arrows to Scroll Tabs in TabStrip Control Not Shown

Article: Q151078
Product(s): Microsoft Visual Basic for Windows
Version(s): WINDOWS:4.0
Operating System(s): 
Keyword(s): kbGrpDSVB

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Visual Basic Standard Edition, 32-bit, for Windows, version 4.0 
- Microsoft Visual Basic Professional Edition, 32-bit, for Windows, version 4.0 
- Microsoft Visual Basic Enterprise Edition, 32-bit, for Windows, 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.

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
------------------------------

1. Start a new project in Visual Basic. Form1 is created by default.

2. Place a TabStrip control on Form1.

3. 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.

4. 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.
