PRB: Combo Box Displays Incorrectly w/ Large DisplayCount

ID: Q185083

The information in this article applies to:

Microsoft Visual FoxPro for Windows, version 6.0

SYMPTOMS

When you have a large value set in the DisplayCount property of a combo box, the drop-down of the combo box either does not display or displays incorrectly.

RESOLUTION

Use a smaller DisplayCount value.

STATUS

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

MORE INFORMATION

Steps to Reproduce Behavior

Create a form.

Create a custom array property, something like myarr[1].

In the INIT event of the form, place the following code:


      DIMENSION Thisform.myarr[1000]

      FOR i = 1 TO 500
         Thisform.myarr[i] = STR(i)
      ENDFOR

Place a combo box object on the form.

Set the RowSourceType to 5-Array and the RowSource to Thisform.myarr.

Set the DisplayCount to 150.

Save and run the form.

Click the drop-down array.

Nothing shows up. Change the DisplayCount to a smaller number like 50 to fix this problem.

NOTE: If you change the DisplayCount property to 80 or higher, depending upon where you have your combo box in the form and the size of the Visual FoxPro desktop, you may see that the drop-down gets detached from the combo box.
