Help needed with Help

[HennekensSM]

I am trying to call specific topics from a HTML Help file with the following line of code:
HTMLHelp(0, "d:\turboint\help\tvwinint.chm", 2, nTopic)
but no matter what the topic nr is it always comes up with the first topic (default).
How do I need to change to code?

Oke, I think I found it.
When using the function as follows
HtmlHelpPopup(0, "d:\turboint\help\tvwinint.chm", 0, "idh_introduction.htm") it works, BUT not always. It randomly GPF's.
Has anybody why these random GPF's occur?

Stephan,

We have tested HTMLHelp(0, "d:\turboint\help\tvwinint.chm", 2, nTopic)
and it GPFs both in XP and Vista

Its difficult to know why as we are invoking an OCX (as a DLL) function

maybe we should try a direct call implementing a C wrapper instead of using DLL FUNCTION command

Thanks ANtonio. Would be most welcome if you could find a solution for this problem

Antonio,

in the C:\BCC55\INLUDE I found htmlhelp.h.
Could this file be of any help to find another solution?

The problem is that VISTA does not support classic help (.HLP) anymore, so we will have to change to Html Help.
Any suggestion to fix this problem is welcome.

You can download the appropriate dll from microsoft msdn to support help files

If you click on a hlp file under vista, you will be guided to the appropriate link. Then you can use all hlp files under vista.

I have downloaded the file a month ago but i do not remember the link

Hi Richard,

thanks for advice, but which dll are you pointing at? Is it htmlhelp.dll? Can you sent it to my?
If have search the web for that file but couldn't find it.

The frusting think is that this can work, at least it works with a small - program I wrote. Both - and FHW are build on xHarbour, so..

This could be a solution: simply call HH.EXE with some parameters.
Winexec("HH.EXE <nTopic> <myhelpfile.chm>")
It actually works (if HTMLHelp is installed of course).

Now there is another problem: At startup there is definition for F1:
SetKey( 28, { |nKey| MyHtmlHelp(IDH_INTRODUCTION) } )
Pressing F1 should call the function MyHtmlHelp(), but instead there is message 'No HELP file available'. Although not defined by me the function HelpTopic() is called. What can I do to change this behaviour?

Code: Select all

#include "Fivewin.ch"


FUNCTION MAIN()

    LOCAL oDlg

    LOCAL cVar := SPACE( 30 )

    SETKEY( VK_F1, { || MyHelp() } )

    DEFINE DIALOG oDlg

    @ 1, 1 GET cVar

    @ 3, 1 BUTTON "&Close" ACTION oDlg:End()

    ACTIVATE DIALOG oDlg;
             CENTER

    RETURN NIL


STATIC FUNCTION MYHELP()

    ? "Help!"

    RETURN NIL


FUNCTION HELPINDEX()

    RETURN NIL


FUNCTION HELPTOPIC()

    RETURN NIL


FUNCTION HELPPOPUP()

    RETURN NIL

Stephan,

Have you looked at the FWH help file modifications I made for HTML help? They are available on my website here:

http://ourworld.compuserve.com/homepage ... rogram.htm

Look for "CHM Help Code"

It has been quite some time since I wrote them so I don't remember exactly what is there, but perhaps it will answer some of your questions.

Thanks you James.
It seems your solution is the same as the one I found.
