Hi Darrell,

>I have a method that creates a cursor and populates a listbox.
>The columnwidths and columncount are set in design mode.
>In the method that creates the cursor I set the rowsourcetype = 6 and therowsourcetype to something like rowsourcetype = "temp.field1,field2,field3,etc...". On very rare occasions (only in development mode so far) I receive a syntax error on the line setting the rowsourcetype. This line of code is syntactically correct but for some bizarre reason vfp randomly decides it is wrong.

know what the problem with this is or had a similar experience?

I'm sure you are actually changing the RowSource, not the RowSourceType, right? <G>

With a dynamic RowSource, the procedure I use is as follows:

with lstExample
   .RowSourceType = 0
   "Populate cursor"
   .RowSource = "temp.field1,field2,etc"
   .RowSourceType = 6
   .ReQuery()
endwith

I've had trouble when I didn't toggle the RowSourceType.
HTH,
