Does anyone know how to get the C# Help and HelpProvider classes to work with CHM files?

Hi,

I have been having trouble getting the HelpProvider class to work with a CHM file we created using RoboHelp. When the user hits F1, the help file comes up properly, but displays a "Page not found" error in the viewing area. I tried the following in the constructor for my form:

                  this.helpProvider1.SetShowHelp(this, true);
                  this.helpProvider1.SetHelpNavigator(this, HelpNavigator.Topic);
                  this.helpProvider1.SetHelpString(this, "RP_IG_basicinfo");

I also tried:
                  this.helpProvider1.SetShowHelp(this, true);
                  this.helpProvider1.SetHelpNavigator(this, HelpNavigator.Topic);
                  this.helpProvider1.SetHelpKeyword(this, "RP_IG_basicinfo");

Neither seems to work. Microsoft's examples are not terribly helpful.

Thanks

Change
this.helpProvider1.SetHelpNavigator(this, HelpNavigator.Topic);

to
this.helpProvider1.SetHelpNavigator(this, HelpNavigator.KeywordIndex);

That doesn't work as these are not keywords that are in the index. RP_IG_basicinfo is a help topic id. I did some more research, and apparently HelpNavigator.Topic requires a topic filename as a parameter. I tried that (basic_information.htm), but that still didn't work.
