Creating CHM HTML Help Systems

Introduction to HTML Help CHM format

Today, HTML Help CHM is the standard help format in the Windows world. An HTML Help system is completely stand-alone and can be distributed as a single file (for example, "My_Help_File.CHM"). Thus, a CHM file is practically a kind of the portable formats for user manuals, which can be opened on all Windows-based computers since Windows 98. In other words, any Windows user is able to display such a file under Windows 98, ME, 2000, XP, and Vista.


An HTML Help CHM file includes all the features to provide the end-user with easily navigated and comprehensive Help. You are probably familiar with the HTML Help viewer, which has the TOC, keyword Index, and the Search tab, located on the navigation pane to the left side from the topic text.

How you can create CHM HTML Help files

In fact, there are various tools in the marketplace from primitive applications to complex and expensive systems for writing help files that support HTML Help as an output format. However, the common problem of those products is their non-intuitive and sluggish interface, complexity, and high price of about $999 per license or even more! Moreover, you will have to spend a lot of time on learning the product before you are able to create even a simple CHM file for your software product. Now you may be asking if there is another solution to make the process of creating CHM documentation an easier way. Fortunately, the answer is "yes".


HelpSmith, a product developed by Divcom Software, has an alternative vision of creating CHM HTML Help files and technical documentation. If you download and try HelpSmith available on the vendor's web site, you will be surprised by its straightforward and easy-to-use user interface.

Then you can easily add new help topics, create hyperlinks, help windows, insert graphical files and everything the HTML Help system allows you to do; the process of working is actually as simple as working with Microsoft Office applications.

HTML Help Compiler

CHM is not an open file format. So how do help authoring tools allow you to create it? Like other help authoring tools, HelpSmith uses the HHC.EXE compiler to create CHM Files from your original source help project. The HHC.EXE HTML Help compiler is freely available with the Microsoft HTML Help Workshop package which can be downloaded from the product's home page. To link HHC.EXE with HelpSmith:

• On the Tools menu, click the Options command.


• Select "GeneralCompilers".


• Set the full path to the "HHC.EXE" file on your computer (e.g., "c:Program FilesHTML Help WorkshopHHC.exe").


• Then click "OK" to save the modified options.

That is done; the process of working with HHC.EXE is completely transparent to you, making the creation of CHM HTML Help files easy as never before.
