Practically every maker of windoze software figures he knows your
computer and uses better than you and can therefore change everything
including DLLs necessary for your living as he wishes. The safest thing
is a dedicated computer. Next best thing is to do a backup before any
trial installation and if things don't work right, then do a restore.
Definitely a pain on the posterior, but faster than having to find the
conflicts and the damages to the registry and other windows .INI files.
Programmers using VB probably do more of the changeling .DLL because VB
thinks too much for them.
Its almost sure that if it runs in windoze 3 its 16 bit VB.
It would be better to make programs self contained and not depend on
.DLL for enhancements. But if properly programmed in C they would be
much smaller and faster.
There is a fundamental problem in serial communications. The BIOS is
terrible, no buffering so every communications program has to replace
the BIOS and probably does it for all ports. I'm searching for better
ideas today. Looking at PCI bus serial cards, though I don't see you
that can be better than local bus chips on the mother board, and at USB
with serial adapter. At least the USB has a much faster fundamental
speed.
I don't write programs for windoze, on purpose. I prefer OS/2 and most
of my programs don't have a user interface, they are command line driven
but some run as many as 3000 times per hour.
