hello,
actually, i have a few forms, in which 2 of the forms are used for barcode
scanning. the first form of barcode scanning is successfully. but when i
went to the other form where i'm supposed to do scanning again, it can't
work, didn't go into the event "case scanDecodeEvent:".
so i'm quite confused. why the first form i can scan, but the other form i
cannot. btw, the other form consists of a signature gadget too.
hope you can solved my problem.
thank you.
