hello there,
First of all, i want to thank you for such a quick Response I didn't expect such a quick response. I want to say thanks to you for taking out time and reading my code and helping me out a very handful of programmers do that. thanks for the advice that I should not write any code in that instead create a class that inherits from above two class.
Once again I am saying thanks to you
Just curious to know from which country are you from?
