Thousands of scrollbars? Of course I meant thousands of items (using an extreme) with a tiny scrollbar.. :) -- Dee Earley (dee.earley(a)icode.co.uk) i-Catcher Development Team iCode Systems

"thousands of scrollbars" ? Each combobox has one scrollbar. The box doesn't even drop down unless you want it to. Otherwise it behaves and looks exactly like a text field. MM

I think maybe you're thinking that the user has to drop down the list every time and click on the value required, but this is not how it works with typomatic. With typomatic you type into the textbox portion exactly as if it were a real textbox. There are added benefits: you can hit End or Home and immediately jump to the highest or lowest permissible value. MM

I can't imagine someone making that statement about artists and singers, perhaps with the exception of egotistical OOP developers.

Well, should you get bored with the jigsaw puzzles, you might want to try the sample download. :-) -- ..NET: It's About Trust! http://vfred.mvps.org |
