I am trying to create a VB .net application that monitors an OPC tag that is selectable by the user. The user chooses the Machine, ProgID, and ItemID. THe software will monitor this tag<br />
<br />
<br />
I know there are a number of VB.net OPC client development packages out there that should help me with this. I have purchased the Software Toolbox Top Server Extender to try and go that route, but i am open to something else if it works. <br />
<br />
My biggest issue i have encountered is the lack of sample code and guides to help me do this. <br />
<br />
Any advice?

OPC Client  development for PLC tag monitor

Visual Basic is Microsoft’s event-driven programming language and integrated development environment (IDE) for its Component Object Model (COM) programming model. It is relatively easy to learn and use because of its graphical development features and BASIC heritage. It has been replaced with VB.NET, and is very similar to VBA (Visual Basic for Applications), the programming language for the Microsoft Office product line.

Visual Basic Classic

Programming includes both the specifics of the language you’re using, like Visual Basic, .NET, Java and others, but also the best practices in user experience and interfaces and the management of projects, version control and development. Other programming topics are related to web and cloud development and system and hardware programming.
