In Visual FoxPro 5.0x, the SpecialEffect property of a Container control does not refresh to display as 0-flat, 1-sunken, or 2-raised at run time.


Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.


When changing the SpecialEffect property of a Container control to 0-flat, 1-sunken, or 2-raised, at run time, the Container does not reflect the change even after the REFRESH method has been issued. The only way to refresh the Container control is to click on an object other than the form that contains the Container object, and then click back on the form. At this point, the Container is refreshed correctly.

Steps to Reproduce Behavior

  1. Create a Form and place a Container control on it.
  2. Set the SpecialEffect property of the Container to "2 - Flat(Default)."
  3. Change the Name of the Container to TstC1.
  4. Add a command button, named CB0, to the form with the following code in the Click event:

          ThisForm.TstC1.SpecialEffect = 0 &&Raised
  5. Add another command button to the form, CB1, with the following code in Click event:

          ThisForm.TstC1.SpecialEffect = 1  &&Sunken
  6. Run the Form and click on the command buttons several times.

NOTE: The effect of the Container stays the same and does not change to the specified setting of SpecialEffect.

Here is the workaround for the above sample:

  1. Replace the code in steps 4 and 5 from the above example with the following code:

          ThisForm.TstC1.Visible = .F.
          ThisForm.TstC1.SpecialEffect = 0 &&Raised
          ThisForm.TstC1.Visible = .T.
          ThisForm.TstC1.Visible = .F.
          ThisForm.TstC1.SpecialEffect = 1 &&Sunken
          ThisForm.TstC1.Visible = .T.
  2. Save and run the form. After clicking the command buttons, the effect of the Container will now change according to the SpecialEffect property setting.
