Thanks a lot keith, really appreciate your effort to make me understand :) krishna

Mr.Shameel, Can you please make those example's little clear, mean to say.. describing interface & abstract class with the same example by inheriting. krishna

Do you have any particular reason to say never.. krishna

Mr. Guy, I am very much clear about what you said. Now I have another doubt, Is that any rules that abstract class must inherit interface, than we need to override from abstract class ? I can create a normal class which can implement this Interface and use those methods. But here we have to create instance of the class to access those implemented methods. So overall you mean to say that, one of the reason to go for abstract class to avoid creating instance of the class ? krishna

Hi, Mr.Keith I really love you, such a sweet example which opens my eyes. I clear about the abstract class now. But, why I should't use like below code ?? public class Cat: Ifeline { public MakeNoise() { Console.WriteLine("Purrr"); } public LookAround() { Console.WriteLine("Looking"); } } public class Tiger: Ifeline { public MakeNoise() { Console.WriteLine("Roar"); } public LookAround() { Console.WriteLine("Looking"); } } krishna

Hi Mr.Eddy, So you mean to say that, commanbuilder can be used only for simple and single query operation. Another thing is, consider I have a dataset(ds) of 1000 records, and how do I edit dataset, means how to update without using commanbuilder and fetch only updated rows from ds. krishna

Hi Mr. Chistopher In the same way I can create Interface with( add, print method etc). I then Implement this Interface so that I can print from datagrid or datatable. Correct me if I am wrong. krishna

Hi Mr.Pete Even I can use Interface for the common functionality, correct me if I am wrong. krishna

Please give me some practical situation where I can use and where I can't. krishna
