A question of design

[Shawn]

Hi.

Our company and one of our contractors are going to exchange data between
our financial systems. The contractor has set up a web service so that I
can download and upload data between the systems. The data is to be
exchanged in two ways. Sometime during the night the application should
start and download/upload everything that has changed during that day. In
addition to that they want me to create a web application they can access at
any time and download data that is needed immediately.

What is the best way to do this? Should I just create a dll that contains
all the methods needed and then use that from both the web application and
the windows application that should be started during the night?

Any help is greatly appreciated!

Thanks,

Shawn

You should always design your business classes without an interface (other
than a programming interface) in mind. Then you can implement any type of
external user or software interface to make use of them.

Ok, but how do I actually do it? Do I create a class that communicates with
the web service and use that class from the interface or do I make a dll and
refer to it from Visual Studio? Or some other way maybe?

As you undoubtedly have figured out by now I've never done this before :-)

Thanks,

A DLL is a file. A class is software. The software must reside in a file,
which would be a DLL or executable. In this case, it would be a DLL, or, in
Visual Studio, a Class Library.

Thanks.
Do you know any good articles on the area, or books for that matter? I
really need to get myself up to date on this.

If you have Visual Studio, check out the documentation regarding "Class
Library" Projects. The "Class Library" template is one of the New Project
templates that are available.
