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.

MORE INFORMATION

Steps to Reproduce Behavior

Create a new form.
Add a CommandGroup to the form and set the following properties:
Height = 180 Width = 96
ButtonCount = 6
Add a second Commandbutton to the form and set the following property:
Caption = "Click Me"

In the Click method of the Commandbutton, type the following code:

      FOR EACH oControl IN Thisform.CommandGroup1.Buttons
      Thisform.CommandGroup1.RemoveObject(oControl.Name)
      ENDFOR

Run the form, and click the "Click Me" button.

NOTE: Only three buttons in the CommandGroup are deleted and the other three still show up.
