Can we develop a bar code reader application in asp.net if any guy who develop this application please assist me what should i do to make bar code reader application.
I haven't developed an application for that to be frank with you. However, i did some research on the matter, and here is what I found:
Bar code is nothing more than a special "font" whose characters correspond to "real" language characters. For example, a 4 bars character (with different width) may correspond to letter A. In order to "read" barcode, all what you need is a barcode scanner (hardware), it's that one that is usually found in stores and groceries. Then in the vendor application itself (the companion CD) you will find the program that reads the barcode and converts it into real characters. This program usually exposes DLL's so that other programs (and Asp.net of course) can deal with it as classes. Once you obatin that DLL file, just add a reference to it from your Asp.net application, then start calling it's methods and properties like any other class.
Hope this helps.
