Jul 21, 2010I am writing an inventory control application in which a barcode scanner will be hooked up to a laptop computer in our shipping/receiving department. What I'm wondering is, whenever a shipment comes in and the receiving clerk starts scanning the products, what exactly do I need to do in order to setup our database so that the scanner recognizes which vendor/product etc. and puts the data in the correct tables. I've written inventory control apps before but never one that incorporated the use of a barcode scanner.

C# - Distinguish Between The Scanner And The Keyboard
Apr 12, 2011I have a barcode scanner connected to a PC that working with a c# program.now i want to distinguish between the scanner and the keyboard which one is sending data to my program.
somebody said this to me in another topic(but i can't do this yet): basically you can configure the scanner to send some characters that basically tell the computer "hi, it's me". When you see those characters in your input stream, you know the information is coming from the barcode scanner, not from something the user typed on the keyboard. Did you check the manual that came with your barcode scanner? It should have more information about this.

Info From Scanner To Grid?
Aug 4, 2009I want to be able to scan an item and that information be sent to a data grid. I'm able to scan a bar code and have it populate a textbox just fine. My problem is getting it from the textbox to the data grid.
The way it works, the textbox has to have focus so it can accept the input for the item being scanned. I've placed it behind the data grid and it works well like that but I was curious if anyone else knew of a better way to do this.
I'm curious if there is a way to detect if something has been scanned and if so, send it to the textbox or whereever else it can go.

Resolving DNS In Multithreading IP Scanner?
Mar 24, 2012I have an IP scanner which reads computer names / IP addresses from a file into a listbox. It then scans each object to see if the host is alive and reports the results back into the listbox. (Much of the code has been adapted from [URL]
This works fine for both IP addresses and computer names unless the computer name cannot be resovled by DNS. In this instance, the thread hangs which causes the program not to finish.
I have a function below which can tell me if the dns name can be resolved however I'm having trouble integrating this into the code because of the multithreading.
how I would go about integrating this into the main code? I have been trying to add it into the pingclass class area but no joy so far..
