Replied by support on topic Create Simple OPC DA client as .NET DLL
Hello,
thank you for your interest in our products.

You probably just need to reference OpcLabs.EasyOpcClassic.dll assembly. See:
opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...the%20Assemblies%20(.NET).html

and then instantiate like "var client = new EasyDAClient();" and use the API.

There are many examples in the C# and VB.NET solutions that come with product that are just simple console apps and are doing it in this way.

I hope this helps. Let me know if you need further help.

Best regards

Create Simple OPC DA client as .NET DLL was created by JImJImJIm
Hello,
I have used the sample .NET forms demo project EasyOpcNetDemo and it does what I want i.e. just basic read / write.
I will be using the OPC server name and tags from static variables, so no browsing etc.
The demo project declares easyDAClient1 on the form, so how do I declare without a form. I.e what references, using etc do I need to get started?
Is there another demo?

Regards
