The new List Box object offers a myriad of ideas and uses. Here's a quick method you can write to allow a user to delete the selected rows of your list box.

`lbarray is the name of your List Box object
C_LONGINT($pos)

$pos:=0
Repeat
   $pos:=Find in array(lbarray;True;$pos)
   If ($pos>0)
      DELETE LISTBOX ROW(*;"lbarray";$pos)
      $pos:=0
   End if
Until ($pos<0)

Happy Coding!

Hi Jody, it was a mistake indeed. The word "columns" in the last sentence has been replaced with "rows" now.

The heading says deleting the selected Rows of a listbox. The code says deleting the selected columns of a listbox. Which is it?
