    Compiled HTML helpfile does not work when application is installed

    My problem is that I am using a compiled HTML helpfile (.chm) for my
    application help. I have copied the file to the bin directory and the
    helpprovider component is pointing to the .chm file.

    The code in the help button that displays the help is as follows:

    Help.ShowHelp(M e,HelpProvider1 .HelpNamespace)

    It is working fine when I test the program, but once I publish it and
    install it on another pc nothing happens when the help button is
    clicked (not even an error message, nothing). This is very
    frustrating.

    Please point me in the right direction.

    I am using Visual Studio 2005 (VB.Net).

    Cheers

      It is very likely that CHM file on the target computer cannot be found.
      Note that the system doesn't look in application's folder. Do you
      specify the absolute full path to the CHM file? If not, do it on program
      startup. Something like:

      HelpProvider1.H elpNamespace =
      IO.Path.Combine (System.Reflect ion.Assembly.Ge tExecutingAssem bly.Location,
      "myHelpFile.chm ")

          I have tried it with your code, but now I cannot get it to run, even
          when I am debugging...I think my file is not located in the correct
          area..
          is the code that you gave my the only way to get the application path??

              I wrote the code from my memory. I forgot to get directory from
              location. It should be:

              HelpProvider1.H elpNamespace
              =IO.Path.Combin e(IO.Path.GetDi rectoryName(Sys tem.Reflection. Assembly.GetExe cutingAssembly. Location),
              "myHelpFile.chm ")

              This works for me.

                  OK..I will try this...

                  One more question (a stupid one, I know) must I then have the .chm file
                  in the same directory as the program, or within one of the subfolders??

                      You can place the CHM file anywhere you want. But you always need to set
                      the full path so that your program can find it.
