VB6 for Win98 and XP

I have written a program with VB6 on Win98 OS. It contains registry commands
and I/O port commands, among many other things. I am being asked if it can
be used with XP. Will it work on the XP without any problems? Is there a
utility to convert the program to work with XP? What concerns must be
addressed when converting? TIA.

Not sure on the I/O ports but the XP registry enforces security restrictions
where Win98 doesn't. Your API calls may need to be tweaked and you may have
problems with users with insufficient rights. You need to document what
registry values are read and/or updated and test it under XP. A common
issue is people not specifying security rights, or specifying "all access",
in the code used on Win98 and then finding they need to change that
parameter under NT/2K/XP/etc

I have a program that uses an old ISA board.

When I put it on XP I have to use WinIO in order to talk to the board from
VB6
