I'm a bit late to the party but I don't read this newsgroup regularily... So
if this topic is still vacant, here are some hints:
1. I think you simply missed to include the help viewer unit in your main
form. Make sure that you have included "WinHelpViewer" in the uses clause of
your main unit.
2. Assign application.Helpfile at runtime, not at design time. For instance in
the FormCreate event of your main form. Specify the help file with a fully
qualified path, e.g.:
application.Helpfile := changefileext(application.exename, '.hlp');
3. Application.HelpContext(1) does invoke the HLP file by help context numbers
and, because it is a Winhelp file, it displays the help topic in the main help
window. Help context number "1" must be defined in the help file. In Help &
Manual, every topic has a separate entry field for one or more context
numbers. The "topic ID" is *not* a help context number, even if you name the
topic "1". Application.HelpContext will fail unless you have defined
corresponding context numbers in the help file. Make sure that this is the
case (you need the HMX source to check it, the HLP file is a black box).
4. I recommend to use HTML Help (.chm) instead of Winhelp, too. Help & Manual
creates HTML Help as well and the functionality is mostly the same or better.
If you use CHM files, include the unit "HtmlHelpViewer" in (1) and remove

Hello I am in need of some help and guidance in trying to use .hlp
files in Delphi. Our tech writer created some .hlp files for my
application. He used Help & Manual. I am now ready to implement that
file in my application. Of course as luck would have it our tech writer
is no longer here and I do not have the context map of the file.
Nevertheless I down-loaded a helpdemo from Help and Manual to see how
it works. If I press the key to activate the help manual I get the
following error -
"no context-sensitive help installed"
I also tried to guess the context number on my .hlp file and I have
also used 1 and get the following error as well.
1. The .hlp file is located in the same dir as the exe.
2. I have assigned the .hlp in the application part under
3. The source code line I have use when click on the help button
and pressing F1. I use application.HelpContext(1);
Can anyone shed any light on the matter. Any help would be grateful.
