Is there any way to use the HelpTopic value to open a PDF file? That would be a better match to our environment than the CHM option.
I have tried a couple of options, but none work so far:
  • "C:\Temp\PowerCalc User Notes.pdf" (C# won't compile this with the single backslashes"
  • "C:\\Temp\\PowerCalc User Notes.pdf"
  • "C:/Temp/PowerCalc User Notes.pdf"
  • "file:///C:/Temp/PowerCalc User Notes.pdf"
  • "file:///C:/Temp/PowerCalc%20User%20Notes.pdf"
Is there a way to do this?

Thanks, Andrew

Hi Andrew,

I don't think Excel supports this, we're just passing the URL to Excel.
Maybe if it were an http URL, not sure.
