There are two approaches that will work for multicolumn listboxes. One uses the AddItem method, and one uses the AddListItem method.

Using AddListItem():

.AddListItem( pjName,   This.NewItemID + 1, 1 )
.AddListItem( tabledir, This.NewItemID, 2 )

Using AddItem():

.AddItem( cValue1 )
.AddItem( cValue2, This.ListIndex, 2 )
