Can anyone suggest me some good articles on the object orientated programming on the internet? any links would do.
Thanks
Hi,
here you can find an introduction toOOP in VB.NET.
Grz, Kris.

Object Oriented Basics

I found some good articles, but nothing to pull everything together for me. To keep this simple, lets create a class to simply print "hello world" to a label on my page. My questions are:

1) I want to put the class code into an external file that I can reference and use on multiple pages. What do I need to do?

2) How can I have the class generate a string that is displayed on a label since I cant just say labelID.text=string?

thanks

You can do something like.

1public class DisplayString2{3public static void DispString(Label lbl,string str)4 {5 lbl.Text = str;6 }7}89// this is your call to that method from somewhere else.1011DisplayString.DispSpring(this.labelID,"Hello World");

Last time i tried that it worked.

Hi,

That's called business object. Follow these steps:

1. Create .cs/.vb file where you should do something you want.

2. Compile the business object into a usable object. Then you will get *.dll in your project's bin\debug folder.

3. Add your new DLL via "Add Reference" when right click the Solution Explorer.

4. Finish. You can do your job.

The reply above is right direction for you to follow. I hope that you should write your class with return a string or add get method. Then you can use get method to get string in the code-behind file.

Happy programming.
