How can I dynamically (at run time) change the behavior of
Help.chm? My goal is to be able to open a video file of the
appropriate language (French, German, etc). For example, the German
and French video file for a given topic will have the same name but
will be located in different folders. How can we tell Help.chm to
open one or the other?
You can't. Could you handle it by producing different version
of your help file (using build tags to limit the output to French,
German, etc.). Then with your developers you can code a solution
that installs only the required version. Other than that, on your
default topic, have some flags. When a user clicks a flag, the
correct video is opened.
