An application uses Microsoft Point of Service (POS) for.NET 1.12 to claim a device. In this case, applications that are running under a different user account cannot claim this device. When this problem occurs, POS for.NET 1.12 performs incorrect claim logic and incorrectly returns an ArgumentNullException exception. The POS4NET Suite does only support Microsoft POS for.NET 1.12 as mentioned in the Whitepaper (article no 000028572, White Paper - How to develop an application with the POS4NET Suite. With the Honeywell POS4NET Suite V.11413 date December 2018, the Honeywell POS4NET driver support Microsoft POS for.Net 1.14. To verify the OPOS driver is setup correctly, please run the TestApp.exe that is part of the POS for.NET SDK. The TestApp application is found here: C: Program Files (x86) Microsoft Point Of Service SDK Samples Sample Application. If you see your cash drawer in the list, you can then attempt to open, claim, and open the cash drawer.
Symptoms
An application uses Microsoft Point of Service (POS) for .NET 1.12 to claim a device. In this case, applications that are running under a different user account cannot claim this device. When this problem occurs, POS for .NET 1.12 performs incorrect claim logic and incorrectly returns an ArgumentNullException exception. Additionally, successive attempts by the other user account to claim the device fail even after the device is released.
Notes
This problem does not occur if applications that claim the device are running under the same user account.
The ArgumentNullException exception is not the exception that corresponds to the failure that occurs. When this problem occurs, you expect the exception that corresponds to the failure to be returned.
Cause
This problem occurs because only one user account can access the global event that POS for .NET 1.12 uses. POS for .NET 1.12 uses global events to track the status of a device when a service object that uses a named event claims the device.
Note In POS for .NET 1.12, Basic device classes and Base device classes use named events. However, service objects that are based on Basic device classes can provide their own implementation to make sure that only one instance of the device is claimed at any time.
Resolution
Update information
This update provides a security attribute when the global event is created. This security attribute lets multiple user accounts access the global event. If problems occur when an application claims a device, POS for .NET 1.12 performs correct claim logic and then returns exceptions that correspond to the failures that occur.
