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

• Microsoft Visual SourceSafe, 32-bit, for Windows versions 4.0, 5.0, 6.0
• Standard, Professional, and Enterprise Editions of Microsoft Visual Basic, 16-bit and 32-bit, for Windows, version 4.0

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.
