>I just found out that there is a limit on the ItemId that you supply when you use the AddListItem method in a ListBox. The maximum acceptable value is 32767. There is no mention of this at all in the help file, it refers only to an integer, which I assumed would be -2,147,483,647 to 2,147,483,647. This is not the case. It also gives a very misleading error message, Function, arguement, value or type....

>It's not likely that you would have that many items in your listbox, but if like me, you were using the ItemId to tie a row in the list box to a record Id instead of adding an extra invisible column to store the record id, you get a nasty little bug that is only triggered when you have got more than 32767 records in your table.

Yes,
Integer there is 16 bits not 32 bits and limit is 65535 signed (-32767...0..32767).

for ix = 32760 to 40000
 this.addlistitem(str(ix),iif(ix<=32767,ix,ix-32767),1)
endfor

Of course question is now what would happen you exceed that limit too. Probably I would keep actual recnos in cursor and use cursor recno()s as nItemId.
