Excellent point.

I am not that good in c+++ and was hoping to find some one to help me to interface the code from Steve Messer and Emma Burrow. It would be great to reach either one. But it seems difficult.

Can you contact me? How can I contact a member?

That is the best news I got. Thanks, many thanks. It definitely address the objective. Now is time to digest all of it. Thanks again. I will keep you posted

3 users are connected to one pc using 3 usb keypads. A record is shown and each user have to input a number like 7.7 or 600 or 7.5 then they will press ENTER. Done. So as an example problem: user2 starts to type 7 and user1 starts typing 5. the computer is already getting 75. You can see the problem. I need a utility/code to isolate the input. I have seen it in an auction software and also using xbox playing games. In the auction software 3 black boxes are seen in the PC. Once a user starts the black box associated with that user, turn gray. Same as the other users. When all users have pressed ENTER, All boxes are revealed with the entries. Until now we only had to enter one digit per box, so 3 keypads were no problem. The system right now have the 3 boxes in the screen.
