When I try to add a string to the ItemData array I get a type mismatch error. It accepts integers OK.

What is wrong.

ItemData is a collection of LONG. You can't set it to strings.

if you want to store a string, you need to create an array of strings and store item index in the itemdata propery.

yup.... unfortunately they're both right... it can be a pain..

I usually use the itemdata to store a bookmark from a recordset when the combo is populated, then if I wish to retrieve the record relevant to whatever is selected in the combo, I can simply use

Recordset.Bookmark = combo.itemdata(combo.listindex)
and pull whatever data direct from the recordset

ps...my method is a little flawed before anyone points it out - as the bookmark property actually returns a double within a variant.
However with current versions of ADO, the value of the double is always integer, so I can use the itemdata property
<fingers crossed that this doesn't change in later versions...>

to nutwiss :
if it's a disconnected recordset you can store AbsolutePos.

p.s. you should not sort or filter your recodset after ...

nutwiss,  no need to worry, as THERE WILL BE NO LATER VERSIONS of VB... VB has been replaced by VB.NET, which allows the ItemData property to hold a OBJECT reference, so you can use almost ANYTHING you desire.

Yes, Arthur, i know - I meant any later versions of ADO :)
and rkot - I usually do filter or sort, that's why I use the bookmark...

Merlin, hope these suggestions help.
