ID: Q141908

3.00 3.00b WINDOWS kbtool kbprb

The information in this article applies to:

Microsoft Visual FoxPro for Windows, versions 3.0 and 3.0b

SYMPTOMS

After creating a list box, you notice that its behavior is inconsistent when scrolling through the records by using the arrow keys.

WORKAROUND

Place the following code in List2.Keypress to stop the arrow keys from moving beyond the top and bottom:

LPARAMETERS nKeyCode, nShiftAltCtrl if (this.listindex=this.listcount and nKeyCode=24) or;

   (this.listindex=1 and nKeyCode=5)
    nodefault

ENDIF

STATUS

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

MORE INFORMATION

Steps to Reproduce Behavior

1. Create a form, and place two list boxes (List1 and List2) on it.

2. Populate List1 with more items than are displayable so that the scroll

   bar is available.

3. Populate List2 with only a couple of items so that the scrollbar is

   not active.

4. Scroll through both the list boxes by using the arrow keys.

5. Notice that in the second list box, you can continuously scroll up past

   the first list item to the bottom of the list and down past the end of
   the list to the top. In List1 the scrolling stops at the top
   and the bottom of the list.
