Hello,

I think you can learn by looking at the examples we ship with the product, and try to modify them so that they connect to your server.

What you need to do is to install QuickOPC, making sure that at the 2nd page of the installation wizard, you select one of the options that include the "COM development". Then, from the Launcher app, navigate to "Examples (COM Source Code)", and select "Visual C++ Examples (Visual Studio 2012+; MFC, Win32)". This opens a solution with several projects showing things like reading values, subscribing to value changes, etc.

Are you using "Classic" OPC Data Access, or OPC UA?

If you run into problems, describe what they are, and we will try to help you.

Best regards
