Q142156: PRB: Cannot See Objects on Back Tabs If Using VB SSTAB Control

The information in this article applies to:

- Microsoft Visual SourceSafe for Windows, versions 4.0, 5.0, 6.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

The SSTAB control is used in Visual Basic 4.0 to allow controls to be placed on
different tabs and seen when the user clicks that tab. However, when using
Source Code Control (SCC) in Visual Basic, if the form that the tab control is
on is not checked out (read only), then only objects on the top level tab are
seen no matter what tab is selected. This occurs in design mode.

CAUSE
=====

Enabling Visual SourceSafe through the ADD-INS Manager forces Visual Basic into
Strict read-only mode. The SSTAB control relies on being able to change the
properties of the form when you click different tabs in the control. When Visual
Basic is in strict read-only mode, it can't display the objects on the back tabs
because Visual Basic won't allow changes to the form. For more information about
how the SSTAB control displays child controls, please refer to the following
article in the Microsoft Knowledge Base:

  Q150417 PRB: Read-Only SSTab Does Not Display Child Controls Properly


RESOLUTION
==========

The form can be checked out and will function normally in design mode. Also,
removing Source Code Control from the ADD-INs Manager will allow the control to
function properly.

Another workaround would be to get the file from the Visual SourceSafe explorer
and check the Make writable option on the get dialog box, then quit and restart
Visual Basic.

STATUS
======

This behavior is by design.

MORE INFORMATION
================

This is a limitation of the SSTAB control in Visual Basic. There is no way to
address this behavior in Visual SourceSafe. The tab control would have to be
re-written so that it doesn't rely on changing the Forms properties to display
different tabs.
