Initialy I used RubyWin, but after not very long I found that not as good as
perhaps it should be.  Now I am using IRB from am cmd session and SciTE for
general edit / run. It works well, but all things considered I would still
like an IDE.  And no matter what people want to say about unit testing it
would save time.

Compiling ruby with VC++ is easy, as is doing extensions in VC++. See the
readme in the win32 directory. For me one of the nice things is that
everything *hasn't* already been written! There's plenty of interesting
projects out there.

I have been working with Win32ole and have also added the ability to create
com objects using ruby.  It's the easiest way I have found of creating com
object thus far. I have some thoughts on using native interfaces in the
future (all happens with IDisaptch at the moment).  However all things
considered, untill there is a really good VM the IDispatch overhead is
probably much compairable to a standard ruby function call.

Prehaps I'm misunderstanding here but
require "package"

I love this also, although it tends to waste my time.  When write the ruby
code, and I am never statified with it so I end up making it smaller and
smaller.  I hope this will wear off once I my coding style in ruby has
settled and I have decided the best way to do the things I commonly do.

There is a bit of a religious war going on about this one.  I am on the VC++
side, and I think it is going that way. To me it really opens up the pool of
professional window programmers.  One must remember however that ruby has a
UNIX background and they are as likely to want to use VC++ for it, as you
are to want to use AutoConf , make and all those other tools that you
probably know little about.
