Hi Ravi Kumar,

I don't know abt Fist and 3'rd Question

But we can not run our application without web.config File in any web application. If u do it u will get an debug error.

and finaliza is not recommended becauz finalize method is invoked by the System.Gc.collect()
and it is not neccessory that every time the finalizw method will be invoked when the garbege collecter will dallocate the memmory of an object. So if u write the deallocation of an object in the finalize, that is not arequired that it will perfomed perfectly.

I hope you tried running your application from Visual Studio, thats why it is giving errors. The lines written in msdn is, "If your application is not using any configurable sections other than default, it is not necessary to use web.config". so try accessing the application directly from web browser.
it will work

See there is no problem with the dll and all. see the dll is a seperate entity from configuration. this wont affect the dll. you can add reference to the dll and start using the classes and methods in the dll.

Hi Ravi,
Here is the answer of your Q's

Ansewers:
1)Set the CausesValidation = true;
2)base.Show()
3)Error: Type 'Test.Test' already defines a member called 'show' with the same parameter types 4)XmlDocument.SelectNodes(xpath)
This gives the list of nodes that satisfies the XPath expression u r givving as argument.
XmlDocument.SelectSingleNode(xpath)
This gives the first node that is satisfied by the xpath argument.
5)Pls explain clearly..i didnt get wat u want actually...
Regards,
Satheesh

-- RaviKumar --

Hi Satheesh,

interface A
{
public void show();
}
class B:A
{
public void BShow()
{
}
public void show
{
}
}
If you create a instance of class B then the object should not expose the method 'BShow()' to the user.
How will you do this?
Here see,
B b=new B();
then we can access the b.BShow() method,but the method BShow() should not be exposed to the user.

Thanks for your previous answers.

Please send me some OO questions only i will try to solve those.

Thanks & Regards Ravikumar.P
