POS device using Service object OR OPOS confusion....

Question

Hi,

I am using POS for .NET 1.12 and I read couple of article and also I read Sean D. Liming book. I have few confusion which I want to clear myself and I know which is not possible until I put my question here.

• I am using DataLogic scanner which supports "Service Object" and "OPOS". Now to use with POS for .NET if I am using "Service Object" then do I have to install OPOS into my machine?
• To use any POS hardware with service object do I need to install OPOS or just their driver is enough?
• Is there any third party .NET library ready with all POS hardware and I can just use in my project. Let me know if someone knows it.

Thanks

Answer 1

Service Objects and OPOS drivers are two seperate drivers. You choose one or the other, but not both. If the vendor has a service object, use the service object. Use the TestApp in the POS for .NET SDK to verify that it is installed correctly.

There is no universal driver for all devices.

Answer 2

Sean,

I installed correctly POS for .NET and when I am opeaning TestApp it is throwing exception and not running.

I have Windows 7 (64bit) OS. I change permission also but still it is not working. I tried with Open as administrator and still not working.

Finally I am able to open TestApp and it is working fine. Problem is you have to give proper permission to Configuration.xml file where any program can read and write.

Now I have one more question that where Control Object stays and I talked with some vendor and they says if you are using POS for .NET but still you have to install OPOS to install Service object and also up to you which Control Object you want to use.

Can someone more focus on Control Object? Does POS for .NET has its own Control Object?

Thanks
