MORE INFORMATION

Steps to Reproduce Behavior

  1. Create a form.
  2. Create a custom array property, something like myarr[1].
  3. 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
  4. Place a combo box object on the form.
  5. Set the RowSourceType to 5-Array and the RowSource to Thisform.myarr.
  6. Set the DisplayCount to 150.
  7. Save and run the form.
  8. 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.
