Re: How do I create a Key Press trigger in Developer 2000 forms?

It gets me closer but I still don't think it will work. What I'm trying to do is to have a trigger fire each time I see a specific character.
I have input coming from a scanner or a keyboard and the only way I can tell which is to prefix the scanner string with a character (I'd like to use a non displayable ascii character). So if my user scans into a field and that particular character is present a trigger will fire which would tell me that it was scanned input. Since it was a non displayable character I wouldn't have to worry about stripping it out of the box.

I tried using a ~ and stripping off the character but it wasn't fast enough. You could see that character for 1/2 a second.

Thanks,

Jason
