Hi, Bob, and welcome,
Yes, you can create links from one .chm file to another. The
HTML syntax is as follows:
<a
href="TargetHelpFile.chm::/path_to/TargetTopic.htm">Link
text</a>
For example:
<a href="htmlhelp.chm::/topics/chmweb.htm">Click here
for more information</a>
To ensure that you're specifying exactly the right path
information to the target topic:
1) Open the target help file.
2) Display the required topic.
3) Right-click it and then, on the context menu, select
Properties.
In the resulting properties dialog box, you can copy the path
information out of the Address field and abbreviate it
appropriately (you need the name of the target .chm file and
everything that follows it).
For this type of link to work, the target help file must be
in the same folder as your source help file or in the Windows Help
folder, or it must be registered under the following key in the
Windows registry:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\HTML Help
