Q176430: FIX: Controls on Nested Frames on SSTab May Paint Incorrectly

Article: Q176430
Product(s): Microsoft Visual Basic for Windows
Version(s): WINDOWS:5.0
Operating System(s): 
Keyword(s): kbVBp500 kbGrpDSVB
Last Modified: 11-JAN-2001

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

- Microsoft Visual Basic Learning Edition for Windows, version 5.0 
- Microsoft Visual Basic Professional Edition for Windows, version 5.0 
- Microsoft Visual Basic Enterprise Edition for Windows, version 5.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

Controls located inside two nested frames located on an SSTab control may not
repaint correctly at run-time when resized if the SSTab control they are located
on was made visible immediately prior to resizing the control. The incorrect
repaint varies by control, but ranges from lack of a border to not being visible
at all.

RESOLUTION
==========

Two workarounds exist:

- Make sure that controls located on nested frames on an SSTab are resized
  before rather than after making the SSTab visible.

  -or-

- Add the following code after resizing the controls:

        SSTab1.Visible = False
        SSTab1.Visible = True

STATUS

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

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

1. Start a new Standard EXE project. Form1 is created by default.

2. Add an SSTab (SSTab1 by default) to Form1.

3. Draw a Frame control (Frame1 by default) on Tab0 of SSTab1 so that it is
  contained by Tab0.

4. Draw another Frame control (Frame2 by default) inside Frame1 so that it is
  contained by Frame1.

5. Draw a TextBox (Text1 by default) inside of Frame2 so that it is contained by
  Frame2.

6. Add a CommandButton (Command1 by default) to Form1.

7. Paste the following code in the General Declarations section of Form1:

        Private Sub Command1_Click()

           SSTab1.Visible = False  'this could happen in form load, or any
                                   'other event.

           SSTab1.Visible = True            'one workaround is to switch
           Text1.Width = Text1.Width - 50   'the order of these two lines

          'alternate workaround if above workaround is not feasible
          'SSTab1.Visible = False
          'SSTab1.Visible = True

        End Sub
