[DUG] BDS2006 or Rad 2007 & the web

[Charlie]

Thanks Sean. I guess I need to clarify at least one of my questions.

 

1)    I essentially have no database experience except for dBase, Paradox
and Access. If I eventually want to have this application so that customers
could enter orders on the web what do you recommend I consider for a
database

Not those! 

Sql Server Express (free for the db size you are likely to need, use the
dbGo components that come with Delphi) or Firebird.  I use SQL server for
nearly everything.

I have worked some with Sql Server 2005 - I'm pretty sure it is the "free"
version. Will look at that option again.

What are your feelings about MySql?

2)    My customer would like for his customers to be able to access the
application to determine the status of their orders. What have you found
that enables concurrent users to do this?

Not quite sure what you mean here.  Web apps are concurrent by nature.
Desktop apps on different computers can both access the db at the same time
providing you have a suitable database.

Here I mean having customers access the Win32 application by logging into
the company's server upon which (some how) a query would be run to retrieve
and display open orders for that customer that logged in. By concurrent I
mean that multiple external customers would be able to access a view of
their open orders at the same time.

3)    Has anyone been able to take a Win32 application and make in work as a
web application? Where do I start? What version of Delphi do I use? What
database? Was the conversion process very time consuming and costly?

It depends on how well you wrote the original  app J.  If all the data
access is done on datamodules, then it is much easier than if the data
access components are on forms.  Either way, you are starting a new
application and trying to reuse as much as possible rather than converting
the original app.

Unfortunately datamodules were not used with the original application so the
data access components are on the forms. While it wouldn't be a hard thing
to change it certainly will be time intensive to move the components to a
data module or reassign a new database to all of those components. Then of
course if I move to ADO components then that'll be challenging I'm sure.
Really don't have any idea how to pursue that conversion; that is to ADO.

4)    I have tried viewing and studying the demos/examples that came with my
versions of Delphi to learn how to create a web application. I guess I'm
dense but I'm having a difficult time with these. A few months ago I had the
opportunity to work some with Visual Studio. I found tons of tutorial videos
and examples that help tremendously with the learning curve. I haven't found
that with the Delphi examples that I have. Does anyone have any
recommendations?

Look at Intraweb aka VCL for the web.  It is the easiest for what you want
to do.  You will still need to recreate the ui, but you may be able to keep
the data modules.  Use the latest version of Delphi that you can.

I'll look at the costs of Delphi 2009/2010 as well as any updating of the
Intraweb VCL. If there is some way to "keep the underlying logic" then
recreating the UI doesn't stress me too much. But then as I said, I a
fledgling Delphi programmer.

5)    All I am is a guy that always wanted to be a programmer but never
really had the opportunity to program day in and day out. So I'm always in
these huge learning curves. I sincerely appreciate any suggestions you can
give me.

Thank you so much,

Charlie
