PRB: Graphics Do Not Display When Using List Box with Pictures

ID: Q136796

The information in this article applies to:

• Microsoft Visual FoxPro for Windows, version 3.0

SYMPTOMS

Using the code example on page 289 of the Visual FoxPro Developer's Guide to display graphics next to list box items causes inconsistent results. Sometimes the graphics show and other times they do not. Occasionally, when you click an item in the list, the graphics show only momentarily; then they vanish. You may also discover some of the graphics are present as you scroll down in the list of file names and still others that are not.

CAUSE

There seems to be a limit to the number of graphics Visual FoxPro can display using this example. If you select a directory that has fewer files, resulting in a smaller number of items in the list box, the graphics tend to display more consistently.

STATUS

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

Steps to Reproduce Behavior

1. Create a form.

2. Place a list box on the form.

3. In the click event of the list box, enter the following code (also found

   on page 289 of the Developer's Guide), ensuring the path to the graphic
   files is correct:

   FOR iItem = 5 TO THIS.ListCount
      cExtension = UPPER(RIGHT(THIS.List(iItem),3))
      DO CASE
         CASE cExtension = "DBF"
            THIS.Picture(iItem) = "tables.bmp"
         CASE cExtension = "BMP"
            THIS.Picture(iItem) = "other.bmp"
         CASE cExtension = "PRG"
            THIS.Picture(iItem) = "programs.bmp"
         CASE cExtension = "SCX"
            THIS.Picture(iItem) = "forms.bmp"
         OTHERWISE
            THIS.Picture(iItem) = IIF("]" $ cExtension, ;
               "", "textfile.bmp")
      ENDCASE
   ENDFOR

5. Save and run the form.

6. Use the list box control on your form to find the

   C:\Vfp\Samples\Graphics\Bmps\FoxPro directory and watch the graphics to
   the left of the file names. Notice the behavior described above.
