Thanks for taking the time to test. Perhaps there is something strange about my structure. But I'm directly testing by commenting out the dereference pointer method (does not work) and then using the named object method (works). This is converting previous code with the other types of listboxes that had no issues. In all cases I'm building the listboxes dynamically, maybe that has something to do with it. I just tested this again in the debugger stepping through both cases: ARRAY TEXT($colNames;0) ARRAY TEXT($hdrNames;0) ARRAY POINTER($colVars;0) ARRAY POINTER($hdrVars;0) ARRAY BOOLEAN($visible;0) ARRAY POINTER($styles;0) If (True) //Bug in 17 - does not work with collection based listbox pointer. $name:=Pointer_name ($1) LISTBOX GET ARRAYS(*;$name;$colNames;$hdrNames;$colVars;$hdrVars;$visible;$styles) Else LISTBOX GET ARRAYS($1->;$colNames;$hdrNames;$colVars;$hdrVars;$visible;$styles) End if $1 is a pointer to the collection listbox variable and the debugger shows it has 10 elements. The object name on the form is the same as the variable name. If I execute it with the name, $hdrVars has 4 elements. But all arrays have zero elements if I use the dereferenced pointer. > The listbox correctly fired an On column moved event and *LISTBOX MOVED > COLUMN NUMBER*(*;"listBox";$pos1;$pos2) correctly populated. You tried this using a dereference pointer? This was the one that was not working last night that made me decide to post something.
