I was given the task to revisit the web side of our development after years
of neglect. “Sigh”
Recent projects had been developed using PB Webforms. All but a few had
failed a had quickly morphed into Terminal Service/Citrix solution to patch
the situation or been abandoned. The reasons for the failures are well
noted by myself and others on these newsgroups.

What to do.
Appeon was investigated and found to perform and support all our needs
surprisingly well. The main issue with this solution was the dreaded
plug-in installation that seemed to fail a lot and no cross-platform
support. I believe this is still the best option for larger systems with a
small number of targeted users but not an employee self service system with
hundreds to thousands of users

I also looked into other 4GL and RIA tools and found the demos to be
extremely powerful but painfully slow.

How about going back to basics.
After installing visual studio and trying my hand at asp.net and asp.net AVC
I realised how much time I saved developing with the datawindow and couldnÂ’t
convince myself I could start building forms, data linkages from scratch.

Looking backwards.
Our PB Web development from over 5 years back was done using ASP pages
calling the web datawindow component. Thanks to the web datawindow sample
application we were able to add our own functions for just about anything
from creating a PDF file to emailing using SMTP. With a little bit of
server side and client side javascript and a few neat tags the pages hung
together quite well, stable and worked across other browser platforms than
IE.

I have brought some of our older ASP web applications up to a newer PB
release 11.2 in-line with the other client applications and IÂ’m feeling a
little more confident in the direction of our short-term web development.
They may not be pretty but are stable, fast and relatively quick to develop
thanks to the datawindow. Sample of a maintenance screen attached.

What is wrong with this approach moving forward?
Maybe I should start looking at calling the web datawindow component with
asp.net and learn c#.
Is the web datawindow component still supported in PB12 or 12.5?
My knowledge of .net is a little limited but would it be possible to deploy
a .net web datawindow component/assembly to function the same way?

Hi Michael;

FYI: Have a look at my "eStore" example on SourceForge (link listed
below after my signature). This is a fully working example of ASP/ASP.Net
web pages (originally maintained out of PB until PB 11.5 when Sybase dropped
Web Targets <grrrrr>) that shows an application calling my EAServer based PB
framework. The framework in turn uses NVUOs with HTML DW's to drive the
whole web application.

All we would need to do these days is change the HTML templates to use
HTML5 plus the newer CSS3. Then add PB 15's HTML5 DW feature and the whole
thing would be cross-browser capable. :-)

BTW: Appeon is looking into HTML5 support.

Nothing. Personally, I think it's still the best option for many
cases. If you want your web app to look like a web app, not
"something" being simulated in a browser, then this is the choice
unless you get a lot of benefit having it look a lot like the original
app. For functionality targeting a different set of users than those
that use your C/S version, I'd say there's a lot of usability and
functionality arguments to be made for your approach. (I'm sorry, but
telling browser users they can't use the Back button is just lame.)

Good luck,

Terry and Sequel the techno-kitten
