BUG: FOR EACH Fails to Remove All Objects (176895)


The information in this article applies to:

  • Microsoft Visual FoxPro for Windows 5.0
  • Microsoft Visual FoxPro for Windows 5.0a
  • Microsoft Visual FoxPro for Windows 6.0
This article was previously published under Q176895

SYMPTOMS

When you use FOR EACH in Visual FoxPro version 5.x as a looping mechanism to remove all objects in a container, only half of the objects in the container are removed.

RESOLUTION

Wrap the FOR EACH command with the DO WHILE command. The following sample code is the workaround for the problem illustrated in the Steps to Reproduce Behavior section.

Replace the code in the Click method with the following code: 
      DO WHILE Thisform.CommandGroup1.ButtonCount <> 0
      FOR EACH oControl IN Thisform.CommandGroup1.Buttons
      Thisform.CommandGroup1.RemoveObject(oControl.Name)
      ENDFOR
      ENDDO

STATUS

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