C#: CodeBehind and Code Re-Use Using Inheritance in windows applications

[janisgs]

Hi

Is there a way to seperate code of interface in windows applications
for various design purposes? Just like it can be done in ASP.NET, one
code can be inherited in different skins with different design.

Sincerely
Del

of course there is a way. It is called layered application. usualy
layers are
DAL - Data Access Layer,
BL - Business Layer
PL - Presentation layer

DAL and BL are contained in Class library projects. You can have in on
solution Class library project with BL and DAL and Winform or\and Web
Application for Presentation layer.

I hope this helps

Thanks Galcho for your response! Can you drop an example of building
layered application in studio 2005?

"Expert C# Business Objects" is a good place to start reading, and a
handy investment.

Our implementation using the new System.Windows. Forms.BindingSo urce as
the base class for our business object. I believe you must be using
..Net 2.0 to take advantage of this.

Now our business object can be used as a datasource for any data bound
control, and we can put our business logic into the class. For example,
our business object has an Update() method that validates the data, then
calls writes the changed data back to the database. If validation
fails, the record is flagged in error. A detail form with an error
provider on it can then display the appropriate error message.

It isn't really possible to send you code examples because 1) I'm not
sending out proprietary code ad 2) It would take quite a while to put
together an example for you.

If you still aren't sure how to proceed, you might consider contracting
a local consultant for a couple hours just to get you started. That's
what I did, and it was money very well spent.

Well, i thought that it would be as easy as in asp.net, where you just
inherit the code in aspx page.

I posted item with attachment but I am not sure if web based reader
would show posting

you could you Outlook Express instead (if you do not get it)

There may be an easier method, but this is the one that I use. The nice
thing about using such an approach is that even though you invest more
"up front" time, your payoff is enormous because the right business
object can be used for so much more than just presenting data to your
constituents. We've gotten application creation down to the point of
creating an application shell, running the application, and then
configuring the datasources at runtime with a propertygrid. Essentially
the entire app is the XML config file saved from propertygrid.

This saves a lot of time because I won't need to spend much time messing
with application interfaces now. Instead, I can focus on database
design and playing hockey at lunch time.

You are right, cant see item, and as this is my first day here in
discussion group, not sure how to get it thru Outlook Express :/ :)
Maybe you could send it to my email? ja*****@gmail.c om

This sounds like an engine, that you gain the programmatical result
without programming. Actually thats why i am interesting how to get
various interfaces under one code-behind (for different projects there
might be different design)
