Hello Ulianov
You can download our OPC server package that includes a set of Visual Basic examples that detail the development of either very simple or very complex OPC clients completely in VB including the ability to browse OPC tags from the server. The code will work with any OPC server.

The code is intended to be used freely. We also have source code available for our C++ OPC client as well if you need that. If you use our web based install you can select only the OPC VB examples saving you a considerable amount of download time. I would suggest getting the whole package if possible as the supplied OPC server includes a demo application that can be used with the Visual Basic code immediately.

Hope this helps.
