RE: GUI development tools

[Walden Leverich <walden@xxxxxxxxxxxxxxx>]

IMHO there is a simple answer to the performance question. "Poorly written
programs perform poorly, well written programs perform well." I've written
C++, VB and Cool:Plex (aka Obsydian) programs that access AS/400 data via
ODBC and have sub-second response times. I've also written AS/400 5250 RPG
programs that take 30 seconds to respond. It's simply a case of coding well.
A big rule would be that these cool "data widgets" aka bound controls will
generally cause you trouble. That isn't to say they are useless, just don't
simply throw a couple of the on a form and think you won't have performance
problems.

Subject: GUI development tools


The VB thread kind of coincides with a current interest of mine.  We're
looking for a GUI development tool to develop apps that have an odbc
connection to the 400.  We're not going to rewrite our order entry or merge
purge applications, but we're thinking of doing actual file access.  I've
heard bad things about performance in applications that do a lot of IO.  The
recent Access discussion didn't make me feel real secure.

I'm interested in hearing about people's experience with GUI tools,
particularly performance.
