Sometimes you just *have* to have all 4000 items available in the list- I have a commercial application for the motor industry, do you have _any idea_ how many different parts those guys need to keep tabs on? And how many different ways they might try to name the same part? So, this app gives them ALL the part names sorted numero- alphabetically in a single list, so that they can browse it when necessary - there's also a button to allow them to search for a string fragment if they're sure it's in there somewhere, but not where they thought. It takes a couple of seconds to fill the list box (reading from disk with no cache hits), but they don't really notice this, they're engineers, not typists, and have generally only got two or three characters in the queue by the time the list is displayed, and are still looking at the keyboard... :-) Over the hols, I'll have to write my own handler, since I'll need to be able to cater for at least 10K parts, so I guess that I'm a tad disappointed with MS too, but I have to say that the speed of what they _have_ supplied is quite impressive, and I'm not known for praising Microsoft often. If any of you are _really_ wary about writing your own handler, mail me sometime in the New Year, and I'll send you my stuff BWO an example. Dave. ----- Disclaimer - I never claimed anything!
