Yes, I started a thread two years back. However, I did not get any feed back after that. I am back to this topic again as I deperatly need to do.

Here is the copy of what I said last time.

Dear Paul,

Thank you very much for the reply. You gave me enough information to start playing with the HtmlHelp API. However, I haven't yet suceeded in producing anything useful.

I have been using winhelp to display selected help topics. Using command like:

LERR=winhelp(ihwnd,'C8INFO.HLP'//char(0),1,I_Topic_ID)

As with Vista, winhelp is not supported anymore, I am now trying to replace winhelp with HtmlHelp commands to display specific help topics from .chm file.

Following code opens a window. However, it does appears immediatly.

STDCALL HTMLHELP 'HtmlHelpA' (VAL,STRING,VAL,VAL):INTEGER*4
INTEGER,PARAMETER::HH_DISPLAY_TOPIC=Z'0000'
INTEGER,PARAMETER::HH_HELP_CONTEXT=Z'000F'
INTEGER,PARAMETER::HH_INITIALIZE=Z'001C'
INTEGER,PARAMETER::HH_UNINITIALIZE=Z'001D'
INTEGER dwCookie
LIBRARY "c:\windows\system32\hhctrl.ocx"
dwCookie = 0
i=HtmlHelp(0,0,HH_INITIALIZE,LOC(dwCookie))
print*, i, dwCookie
i=HTMLHELP(0,'c8_help\c8info.chm'//char(0),HH_DISPLAY_TOPIC,
+ 0)
c + 'html\c8in0001.htm')
c i=HTMLHELP(0,'D:\contram\c7\c8_help\c8info.chm',HH_HELP_CONTEXT,
c + 1000)
write(*,*)i
i=HtmlHelp(0,0,HH_UNINITIALIZE,dwCookie)
write(*,*)i
end

Sorry,

There is correction in my statement in the last post

"Following code opens a window. However, it does appears immediatly."

should be replaced as

"Following code opens a window. However, it does disappears immediatly."

There are two problems with your code.
1. You need a pause statement of some kind in the code otherwise the help window closes immediately.
2. You need to run it as a windows program (WINAPP).

Dear Paul,

Thank you very much for your reply. It is working. Now I need to play with the code to select a specfic topic on demand.

There is a MUCH, MUCH, easier way to use hypertext help. This is the menu stuff:

You are right in saying that your method is much easier but calling HtmlHelp, in theory, allows you to directly access given topics etc.

Paul,

MSDN reckons that you can access given topics in a .chm file using HH.EXE ....
