Scan barcode from anywhere

Hi everyone

I am developing an billing application in wpf that is integrated with barcode.

Column is like as follows

ItemCode, Description, Qty, Rate etc

Whenever user type ItemCode or Decription of the item, the relevant items such as price/vat are fetched from the datatabIe and added to the list.

I am generating barcode label with ItemCode (which is unique)

As I found on google that scanner scans the barcode and paste the text on the focussed text but I want that it scans the code (not necessary the focus to be at ItemCode) and fetch the data.

If the focus is not on the ItemCode, user have to click on ItemCode (for focus) and scan the code (which I feel is not a good user experience.

Can anyone help me to get better user experience.

Thanks

Devendra

Hi,

I think you will have to use keyboard hook for this.

Can you look at this thread which may help:
