Open online help in one session of HH

Question

I'm creating an online help in CHM for my application.

To open the help from the application on the appropriate page, I'm starting this kind of command:

hh path/to/help_file.chm::/the_page_i_want.htm#the_section

The problem is that if the user opens a first help dialog, then a second (from the application) he will end up with two help windows. I'd like the second link to be opened in the first window.

How can I do that (is there another way than the plain call to hh)?

Call the htmlhelp api directly within your program? (htmlhelp.h, search for htmlhelpA function)
