We are using a chm file for project specific help in a scada software(WinCC). Using HH_HELP_CONTEXT to call a specific topic with map ID using C script.
The issue is when opening the chm file by double click or directly calling the help file it is working fine and we can browse TOC and contents.BUT when calling specific topic using map IDs the file window is opening but nothing displays.
There is a topic on my site about calling help. See if that helps. I have no knowledge of how help works with scada and don't know if that is the issue.
