Hello everyone. First post ever here. So please be gentle.
The code i'm having trouble is this one:
IF i use the keyboard in my cellphone to enter a not existent code and press the "BUSCAR" button, it shows the ToastMessage indicating that it's offline, and it sets the focus on txtConteo properly. I can see the cursor blinking in the field whether it has a value or not.
BUT if i use a codebar reader, it reads the not existent code, shows the ToastMessage but no edit text view gets the focus. So, if i read another code inmediatly using the scanner, or if i press RETURN in the android keyboard, the app crashes. The app just closes.
I've tried changing the "code end char" on the reader, from ENTER (0x0d) to RETURN (0x0a). Same result.
The only way it works it's configuring the scanner to not sending an ENTER or RETURN. But the user is forced to press the button "BUSCAR".
With 30 codes to scan it's maybe nothing. But when there are 3000 codes to scan, it's not functional.
If anyone could shed a light on this issue, i would appreciate it.
Thanks in advance and BTW, what an excellent language is B4A. I'm loving it so far.
