Hi Zaheer,

I don't know the details of your entry screen, so here are some possible choices..
If the textbox gets it's input exclusively from the barcode reader, then disable it, use a barcode reader connected to a serial port, read from it and set the textbox value to the info read.
I use a routine using a timer and MSCOMM to read from a proximity card reader, extract the info I need to reference a record in a grid.
If the input can come from either the keyboard or the reader, you could still use the routine to fill the textbox value.
