Can anyone explain this intolerable latency on a WAN?

Yowzer.

We actually had that problem at a clients. They had four Citrix
servers running in load balancing configuration. One of the four
would cause corruptions. I don't know if they ever found the cause
because they decided to put all the usages of my particular app on one
of the servers.

But then neither would an Access/SQL Server app.

There seems to be a lot of that going around, particularly among developers.
MS owns Access and, IMO, MS has moved it along
the line from a RAD tool towards being an inter-
active tool. That's fine; it's their product.

Alas, since the advent of Dot Net, Microsoft appears to consider it the ONLY
developer tool. On the other hand, the number of 'Softies who considered
Access a "developer tool" has always been a distinct minority.

From my experience in a previous incarnation in the halls of a major
computer manufacturer, I can "relate" to that. In the 1980s and early 1990s,
I supported a software product that ran on mainframes, but was interactive
via the VM operating system and also, jumping through a few extra hoops, in
the MVS environment. It was much like a PC database application,
implemented on a mainframe. We had a number of customers who loved it
because it was so simple and easy to use to develop small - to - modest
sized applications. But, it was NOT classed as a development tool; it was a
"decision support system". Why? Well, of course, it was developed by a
maverick group in the Midlands Marketing Center in Warwick, England, and
_development tools_ were developed by the _System Development Division_.

Fortunately, the Mighty Marketing and Management Machine in that company had
bigger fish to fry, so didn't influence it to be constrained to not work
nicely for the kind of development for which it was intended.
But I don't see that it's an appropriate tool for
me anymore.

Certainly, it's not the tool of choice for creating web applications.
What does this have to do with Intolerable Latency
on a Wan? IMO, it's very unlikely that a well designed
dot.net/MS-Sql Server would suffer from such
problems.

How about a not-so-well-designed DotNet application? That's the kind of
Access-Jet/ACE application where we see the problems... I suspect Dot Net
developers who didn't know a lot more about their environment than the
Access developers we hear from (and quite often are able to assist to get
something decent running) wouldn't even get far enough to be asking these
questions in their appropriate newsgroups.

Good luck...

Hi Larry

Maybe we're yearning for a time of long ago.

I am hitting myself in the head with a hammer. It hurts and there's a
bit of blood trickling from my nose. Can anyone help?

1. Take some acetaminophen and put ice on the back of your neck;
2. Stop hitting yourself in the head with a hammer.

IMO too many #1 answers have diluted the (once high) quality of CDMA.
 
One of the advantages of web applications is that senior executives
and board members can see real-time, current reports of what's
happening, wherever they may be, provided that place has an internet
connection. My experience is that they like that...

Most programmers are protected from dealing with board members :-).
Many executives have phones with internet capabilities. I don't want
those executives to know that I'm working on techniques for providing
summary database information to their phones lest they develop
unreasonable expectations -- ones that might hinder the efficacy
derived from being able to explore multiple options for the best
implementation possible. The executives' customers also might really
like to be able to access summary database information from their cell
phones or via the internet. At least some standardization is starting
to emerge for most phones -- SDK's mostly along the lines of Mac,
Linux and Windows OS styles along with miscellaneous options such as
browser/javascript or tagged PDF is a vast improvement over
programming that is specific to each phone model or manufacturer.
