Re: How to determine the input method for the textbox control?

Beautiful business model. No manual override. If the barcode scan fails,
just turn that customer away. Didn't need their money anyway.

Hi

Actually this is a requirement from our customer.
They want the operator to scan the CardID.
Manually entered the cardID is not allowed as they afraid the
operator will remember the ID and use it illegally.

Tham,

Some barcode scanner can be set with sending a control code before
or/and after the barcode. That could be a way to determine the
input origin.

Yes, best thing I can think of is use a preamble string from the
scanner and check for that. Of course you can still type the
preamble string with a keyboard..

What are you going to do if a barcode will not scan though?
Usual answer is to key in the number..
If you really don't want to use the keyboard, don't plug it in!
