SWAP CARD READER

[chamara]

I'm Developing System Using Swap Card (Credit Card).My Swap
card reader is a KeyBoard (With Swap card Reading Facility). So I want to control the Keyboard buffer.I want to validate the Information Beforeits get into Text Box. Can I Do It?. If can Please Send me Code as soon as possible.

Try validating the data in the text box's KeyPress event.
If there is any key that you don't want to go through just
set the KeyAscii to 0.

Hope this is of any help to you
