Creating help is a big job. There are tools around to help (RoboHelp, et al.), but they are 3
rd party.
You
can write simple text files, and use the help compiler that ships with
VB to create a help file, but it is a
[u]HUGE</u> job! You have to manually keep track of topic IDs, and so forth, to get it all to link up, and you have to manually "decorate" hyperlinks, bold/italic/etc. formatting.
The description of how to do this is
way beyond the scope of a help forum... (I mean, they have entire college courses on this, an hour a day, 5 days a week, for a whole quarter...)
