Question

Context-sensitive help in merged project (CHM)

Hello all,

there is a lot of information about this topic, but much of what I found concerns old Windows versions and is sometimes contradictory.

The question is: how do I link the master project to the subprojects, allowing the application to call the master with a map ID that displays a page in the subproject? Naturally the TOC should sync to give the appearance of a coherent help system. This should work under Windows Vista (and XP of course) with Microsoft HTML output.

Perhaps you can you recomment a souce for up-to-date info about this? Please excuse if I have overlooked a previous discussion, I did a search but did not find a match. The forum search engine is a bit tricky too.

Hi, Robert,

The information on the Helpware site is still valid, even if it's been around for a long time now.

http://helpware.net/htmlhelp/how_to_merge.htm#ContextHelpIDs

http://helpware.net/htmlhelp/how_to_merge_ctx2.htm

To my knowledge, these are the only published ways to channel a context integer through the master Help file to a slave.

There is an alternative and simpler solution that involves the use of the HTML Help API command HH_DISPLAY_TOPIC, which passes a topic file name rather than a context integer to the master Help file. I've described this here:
