Q166512: PRB: Form Goes "White" when Viewing Tab Order with SSTab Control

Article: Q166512
Product(s): Microsoft FoxPro
Version(s): 5.0 5.0a 6.0
Operating System(s): 
Keyword(s): kbvfp kbvfp500 kbvfp500a kbvfp600

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

- Microsoft Visual FoxPro for Windows, versions 5.0, 5.0a, 6.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When viewing the tab order of objects on a form, the whole form turns white and
none of the objects are visible. If the tab order is being viewed by list, the
form goes back to normal when the OK or Cancel button is clicked in the Tab
Order dialog box. If you are viewing the tab order interactively, you must
choose another object in the Object drop-down list of the Properties sheet for
the form to come back to normal.

RESOLUTION
==========

If you are using the SSTab Control or the Microsoft Tabbed Dialog Control in
Visual FoxPro, view the tab order by list. If the tab order is viewed
interactively, the objects are not visible for setting the tab order.

Alternately, the Visual FoxPro PageFrame object could be used instead of the
ActiveX control.

STATUS
======

Microsoft is researching this behavior and will post new information here in the
Microsoft Knowledge Base as it becomes available.

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

To change how the tab order of objects on a form is viewed, select Options from
the Tools menu, and click the Forms tab. Tab Ordering is in the top right
corner. This can be changed while a form is open in design mode and the change
takes effect the next time the tab order is viewed.

Steps to Reproduce Behavior
---------------------------

1. In Visual FoxPro, create a new form.

2. Place an OLE Container Control on the new form.

3. In the Insert Object dialog box that appears when the OLE Container Control
  is added, select the Insert Control radio button on the left.

4. From the list of controls, select the SSTab Object (if using Visual FoxPro
  5.0) or the Microsoft Tabbed Dialog Control, version 5.0 (if using Visual
  FoxPro 5.0a) and click OK.

5. Right-click the control when it appears on the form and select Edit from the
  shortcut menu that appears.

6. While the Tab control is in edit mode, place a label and a text box on the
  first tab (page) of the control. In the Property sheet, verify that
  OLEControl1 is the currently selected object by looking in the Object
  drop-down list. The label1 and text1 should be indented under OLEControl1.

7. Now select Tab Order from the View menu. If it is set to By List, the Tab
  Order dialog box appears. Note that the form goes white--all the objects
  disappear. Click OK or Cancel and the objects will come back. If the tab
  order is set to be viewed interactively, the form goes white-- all the
  objects disappear. To get them back, select an object other than OLEControl1
  in the Properties sheet Object drop-down list.
