The scanner like a keyboard. When I scan barcodes to WORDPAD on wince scan result return.

When I scan barcode on my App creates an exception that "data corruption". How can I fix the problem? How can I use the scanner?

Hello erkank,

Did you try to create a editbox on your form and check your barcode data lenght?

Generally keyboard barcodes ends with #13 character (carriage return). Can you recevieve that char?

Thank you for your advice. But I try the exception agains. I think when Barcode scaned, main form KeyPress Event not fire like on Windows.

I am not sure of Windows CE's form keypreview property. Maybe you should check it.

The Application for me OK. I could make it.

I think if hand terminals barcode scanner scans barcodes line a keyboard we use this steps (I used them);

-If application raise an exception line 'Press OK to ignore and risk data corruption.' when press the scan button. We must destroy the message on ApplicationProperties.OnException event.

-There is no differences between speedbutton and button for focusing. The Application runs in windows the scanner don't focus the speedbutton but the speedbuttons has focusing in wince.

-We should use an edit or memo for barcode scaner and the edit control must be forms active control.

-I use keypreview property but I can't use form keydown event in wince. I don't understand. I use keypress.

That's all. I tried this steps and my application is OK.

Take it easy for eveyone. Good Luck...
