• Microsoft Point of Service for.NET (POS for.NET) v1.12 is a class library that enables POS developers to apply Microsoft.NET technologies in their products.
• Fixes a problem in which applications receive an ArgumentNullException exception when they try to claim a device in POS for.NET 1.12. This problem occurs when an application that is running under a different user account claimed the same device.

Hi, I am trying to develop a program to control two barcode scanners. I found the article above and tried the samples in the article. After following all the steps in exercise I, II and III. the application can detect the barcode scanners. However, it produces errors when I select the demo scanner and click the activate button. I have checked with the coding, setting of registry keys, service object and hardware id. I couldn't find anything wrong.

Thanks for any helps.
Here are the errors:
System.ComponentModel.Win32Exception was unhandled
Message='A device attached to the system is not functioning'
