With "an example"?? That's simply not possible. OOP concepts take entire books to cover. One or two examples in a forum environment simply is not going to be enough to cover the huge scope of your question. About the only suggest we can make is to get a compule of books. Search Amazon for "OOP VB.NET" or "VB.NET Beginner" and you'll come up with a bunch of them.

Sounds more like general homework questions to me.

You're still asking for WAY TOO MUCH information for a forum environment. Don't make me repeat myself.

That article just scrathes the surface. There's far more to OOP than what's in that article.

i hv developed an application in vb.net its having more 50 forms. when i open the same in vs.net my pc become slow. when the application is running, the pc get slow. this application was developed for Electrical Company and having 10 different users to access their option. the database also having much more (means 2 lakhs) record under one table not in every tables. some its giving error 'time out expired' while retrieving datas from the table.
what is best way to develop an application. what is procedure. what are things to be careful while developing an application?????. for retrieving data im using sqldatapter and filling in dataset. after that im not closing the connection. i read from some vb.net help book that if you fill the tables in dataset, after its filled in dataset its closing the connection automatically. im using sqlcommand and executenonquery to store information to the table.
it's a memory problem, obviously i would need to figure why so much memory is being used. It could be a problem with my code or perhaps just a problem due to the amount of data im retrieving.
kindly help

Entire books are written on this subject alone. There is really no way of answering your question because of it's broad scope.
Rafeeque Ahmed wrote: what is procedure.
Again, another book.

And another...
Rafeeque Ahmed wrote: it's a memory problem, obviously
No, it's not. It a major design problem with your app. Since we know nothing of your application, what's it's purpose is, what the slow parts of the app are, the structure of your database, the amount of data you REALLY need to be retrieving, are you using the appropriate methods for manipulting the data, are your queries optimized for the data and operation in question, ..., on and on and on, ... There is really nothing we can answer here other than suggesting a design review of your database, then a complete code review to veryify that you're doing things in the most advantageous way possible.

Your application performance problem can be one or more of many things. I would re-look over the entire design and see where there are potential bottlenecks and address them.

Like Dave said, this would require entire books or full term university coursework to cover...I would look around at a few books or on the web...

Iam using Webbrowser control in VB6 for Reporting and Printing.
While printing it also prints IE Header and Footer.
I searched many times from the google. But i didnt get any relevant result also.

And also to diable the Keyboard events for the Webbrowser.
Its very urgent!!!!
Please guide me.

Hello,
How can i load a textfile into a textbox?
i tried:
dim txt as string
FileOpen(...)
Input(1, txt)
textbox1.text = txt
FileClose(1)
when i try this, i only get the first line of the file and not the lines below. how can i open a complete textfile and load it's (complete!) text into a textbox?
thanks in advance, 
--Zaegra--

FileName = App.path & "\TextFile.txt"
Open FileName For Input As 1
whole_file = Input$(LOF(1), #1)
Close 1
Text1.Text = whole_file
Note : if the file contains more than one line you have to set the textbox control to multiline is true and their scrolls.
Thanks & Regards
