Hello there,

I have created a .chm file using the Microsoft HTML Help Workshop.  I now 
want to have my C++Builder 2007 application display the .chm and a specific 
help topic.

I have placed the HtmlHelp.lib in my lib folder and the HtmlHelp.h in my 
include folder that came with the Microsoft HTML Help Workshop.

In my code:

#include <htmlhelp.h>

HtmlHelp(Handle,"my.chm",HH_HELP_CONTEXT,262);

When I try to compile I get an Unresolved External on 'HtmlHelp'!

So I must have the wrong versions of HtmlHelp.lib and HtmlHelp.h.  I have 
tried the ones that came with Microsoft HTML Help Workshop.  I have tried 
the ones that came with my install of C++ Builder 2007.  I have tried using 
IMPLIB to create my own HtmlHelp.lib from my hhctrl.ocx.

Does anyone else call on a .chm file using HtmlHelp()?  Should I be doing 
this another way?

Thank you for any help you can offer.

Chad

You may want to try the C++ Builder HH Kit, available from:

http://helpware.net/downloads/index.htm#TheCBuilderHHKit

This comes with a version of htmlhelp.lib that is compatible with C++
Builder.

Hi Chad 

You should probably ask this question in:

borland.public.cppbuilder.ide

Thats where the guys that know a lot about the IDE hangs out.

Kind regards
Asger

That .lib file is not going to be compatible with CodeGear's compiler, as it 
is meant for VC++ instead.

You did not add the .lib file (well, a compatible version of it, anyway) to 
the project.  Simply putting the file into the folder is not enough for the 
linker to use it.

I suggest you go to http://www.deja.com and search the newsgroup archives. 
The topic of using HtmlHelp has been discussed in detail many many times 
before.  In fact, the VCL has supported handling CHM files in the 
TApplication::HelpFile property, just like it does for HLP files, since BCB 
6.  You do not need to call HTMLHelp() directly.  All you need is to call 
RegisterViewer() to register a class that derives from the ICustomHelpViewer 
interface.  The VCL handles the rest for you.  The VCL has a native 
implementation of ICustomHelpViewer for HLP files, but you can add your own 
separately as well.  There are plenty of third-party implementations 
available for HTMLHelp, for example:

    http://cc.borland.com/Item/22408

    http://www.torry.net/vcl/vcltools/help/sphtmlhelp.zip

    http://www.ec-software.com/comppage.htm

Just to name a few.
