Connecting Visual Basic 5/6 to TOP Server

The best way to get TOP Server information into your custom Visual Studio 5 and 6 project is through OPC.  Since OPC DA technology currently uses COM interfaces the best method to use is an off-the-shelf ActiveX product for OPC DA connectivity which is tested and supported.

Software Toolbox offers a number of OPC DA tested clients for your Visual Studio 5 and 6 development environment including sample code to get you started.

OPC Data ActiveX for runtime free development with little to no code.
