The barcode scanner inputs the scanned value into the which ever Text box in focus at the moment.My question is ,I want to the scanned value to be stored in the particular text box only,say txtCvrNo
I already have a text box to enter some advance amount in the form.By some mistake if my client scans the barcode value in to this text box the application will consider it as advance amount. I want to avoid that.Is there any way ?

Most bar code scanners append a newline character after the bar code data. Modern scanners let you disable this feature. Check your bar code scanner manual for details. The USB bar code scanners at barcodingfonts.com have tbis feature.

barcode scanners works like any input device like a key board. it accepts the input in the control having focus only. so you need to scan / use the device while focus on desired control only.
