[DUG] Delphi Web Service & Client

[Charlie]

Rob, thanks so much for the reply. 

I've been told that it is possible to have the internal local application
(Win32 application) and the web application accessing the same database
which resides on the website by using web services. This prompted my
question about Web Services and Clients. I have no idea if this is
practical, doable or even a wise thing to do. Since I am a intermediate
Delphi programmer and since the application is for my only client and since
hosting on a Windows web server is no problem, I would sincerely appreciate
any advice.

Can I ask you another question. Or a couple?

Presently I'm using BDS 2006, InfoPower Suite 2007, AceReporter and dBase.
The original application was Accounting for Delphi (ColumbuSoft).  I've
modified the original application extensively because of the 'business'
rules. I use TTables, TQueries & TDataSets and data aware components
extensively. The application is on a WinXP Pro peer-to-peer network and is
encountering speed issues. Essentially the application is an order/entry
application which also creates manufacturing documents which the plant
employees use to create the items ordered. Additionally it exports to
QuickBooks an invoice for the order. I really want for the customers to be
able to enter their own orders as opposed to faxing or emailing them. Hence
my interest in a web application.

Any course of action will require a huge learning curve for me. My only
source of help is forums like this. Given this

1)      Should I continue with Delphi

2)      and dBase

3)      Are there better ways than web services to allow customers to enter
their own orders

4)      If I continue with Delphi should I upgrade to RAD Studio 2010

5)      Would .NET Remoting Service (whatever it is) be something to use

6)      Apparently MS SQL and MySQL seem to be the de facto databases of
choice for web hosting companies; are their reasons why I would use one over
the other. There is no cost incurred from the web host to use either.

7)      I have done some work with Visual Studio WinForms and  a web
application

Sorry to be such a bother. Again thank you so much for helping me.

Hi

I developed a Delphi web service (SOAP based) and delphi clients.  This
worked fine but has the disadvantage of only running on Windows web servers.
This was of course the requirement for the next web job we had.  This time I
used PHP for the web service and passed the data as XML.  I developed a
system that can be used again and again for any web site DB and table
structure, however if I had not done this the task would have been very
simple.  I would strongly recommend using PHP for the web side of your
service and then just use standard Delpi / indy for the client side.  It
works well, is portable and fast.  There are lots of PHP examples on the web
you can use.  

Hope that helps :)

but in each instance I have encountered errors when trying to compile or run
the service.

Oh I'm using BDS 2006 Pro.

Thank you,
