Calling .CHM help with a specific topic

[TInloes]

I am trying to call help with a specific topic.

In the past I used .HLP files and used this method:

(setq helpfilename "myhelpfile.HLP")

(setq helptarget "Menus")

(help helpfilename helptarget)

I am now using .CHM help files and I want to accomplish the same thing - open a specific help file to a specific topic.  The old method no does not work with the .CHM file.  I have added an alias for each topic and have tried calling with the Topic ID, the Alias and the Help Context Number (in decimal and hex).  So far nothing I have tried works.

Does anyone know how to accomplish this using Lisp.

Thanks

(defun ActiveXHelp ( topic )
    (startapp 
        "hh.exe"
        (strcat
            (findfile "acadauto.chm")
            "::/idh_"
            topic
            ".htm"        
        ) 
    )
    (princ)
)

(ActiveXHelp "HasAttributes")

Another option is to look at setfunhelp

(defun c:fooTest ()
  (getstring "Press F1 for help on the fooTest:var1 command:")
)
(setfunhelp "c:fooTest" "myHelp.chm" "var1")
