Write your reply.

assistant: Hello Bucky.
Look harder and you'll find vbrun400.dll in windows\system.
Yep, and 400k is a real pain in the arse when your app could be 40k if
written in C - and this may be the case for some small vb apps.
Version 4 is bigger - around 800k ISTR. Not very practical to download this
is it?
It aint. Try running it on a machine without VB installed.
The ANSI C spec says nothing about programs actually working. The US Marines
hand book says nothing about eating meals.
All VB apps need it.
Yep
I'd say that was bad planning, but it could be done.
Well, yes, but in any non-trivial application you tend to have multiple forms
open at once.
Modules are never required. They are merely there for convinience. Personally
I believe that most code should go in modules and only that tied to a form go
into a form. If you aren't interacting with a human, there will be no form,
and so no code in it.
I would have a module which provided functions for message base access. One
for packet access. One for processing kuldges, and a few other 'service'
modules. A sub main() would tie the whole program together, though it would
be very high level, something along the lines of:
    if (more bundles to toss)
        toss next bundle
I would also be likely to have a % complete bar. A form would handle all the
nitty gritty and have one external function - SetPercentComplete().
Yes
Yuk :-(
Same effect can be achieved using Shell if the programs are compiled.
Virtual memory means that you rarely run out of memory - the whole machine
just gets dead slow.
It certainly can handle big projects, and thousands of subroutines sounds
plausible, though I haven't tried it :-)
Have you ever tried programming C? It can handle thousands of subroutines
with no trouble at all.
