USB Port

:confused:Hi, I have to write a program to capture a usb barcode scanner,... as you all know, when you scan a barcode, it acts like a keyboard & just sends the barcode text to the active window. all i have to do is just to write a program which runs in the background & captures those scanned barcodes to a text file and it would not sent it to the active window,.. it's like windows message intercepting for your own purpose. i really apprecite if you can give me any sample code, or any clue. Thanks in advance

You say it's acting like a keyboard, are you implying that it's using a generic Micorosoft Human Interface Driver? /\ |_ E X E GG

yes i think so, i didn't install any driver, by theway i have windows xp pro sp2. it should be same as the usb keyboards.

Well then you can use some already documented APIs to interface with your device. I will post more details the open of business Monday. /\ |_ E X E GG

Search the web (or codeproject) for keyboard hook, and you'll find what you look for. But probably it'll be hard to find something in C#, it's something that easier done in C++. I see dead pixels Yes, even I am blogging now!
