There’s unfortunately no library available for VB6. SmartInspect currently supports .NET, Java and Delphi only. However, the SmartInspect protocols and log file format are clearly documented and you may be able to write a custom library for VB6:
SmartInspect Log Formats and Protocols
It’s a bit of work but your custom library would be able to use the Console just like the other built-in libraries. We are happy to help in case you want to do this. E.g., we have a minimal library implementation for PHP which provides a good overview of what’s required to communicate with the Console. It can be found on the SmartInspect Resources site.
