Hi Michel,

>I'm trying to use incremental search in a combo box which contains a large number of items (all the cities in a province, which can be over a thousand in some cases.) I'd like the user to be able to start typing a city name and the text part of the combo box to show up with the first city name that matches what has been typed so far - this is incremental search, right? The incremental search property is set to .T.

If your combo has its Style Property set to 0, you must have the list dropped down for this to work. You could set style = 2, then it will most likely work to how you expect it. The _DBLCLICK you mentioned, is the value your combo uses before it resets eg: if _DBLCLCIK is low you must type fast or the values you enter will reset, if it is high you may take your time.
