Here's how you can create multicolumn Listbox with RowSourceType=0.

WITH Thisform.List1
  	.ColumnCount = 3
  	.ColumnWidths = "50,100, 100"
	.AddItem( 'One' )
	.List[.NewIndex, 2] = 'OneColumn 2'
	.List[.NewIndex, 3] = 'OneColimn 3'
	.AddItem( 'Two' )
	.List[.NewIndex, 2] = 'TwoColumn 2'
	.List[.NewIndex, 3] = 'TwoColimn 3'
	.AddItem( 'Three' )
	.List[.NewIndex, 2] = 'ThreeColumn 2'
	.List[.NewIndex, 3] = 'ThreeColimn 3'
ENDWITH

2. If I specified RowSourceType to 6 for both
listboxes, The code
SCAN
List.AddItem(table.field)
ENDSCAN
fills both (source and destination) boxes
instead of only the source listbox. Anyone
knows why I am doing wrong here?

The AddItem() is only applicable for the RowSourceType 0 and 1. With the RowSourceType=6 the RowSource should be in the format 'TableAlias.Field1, Field2, Field3, ...'.
