Hi Mr. Ed Rauh

Thank you for reply. Yes, I agree with you. My client is satisfied I was trying to get some way but I could not get it. Because computer does not differentiate, the digit entered by pressing keys or by barcode reader when the barcode reader is connected with USB. Even I tried to use many events like interactive change, key press etc. Anyhow, I tried my best and then I left it as normal

Regards,
