>Ensure the property "NumberOfElements" is set properly, In VFP 3.0 i always left this at 0 when the control source was an array, but when i converted the project to VFP 5.0 it needed to be explicetly set.

I've got a lot of listbox with RowSource of an array. All I did was a This.Requry after I make the array. All work properly.
