There is a very good website out there. It provides detailed information on any topic out there. People call it Google and can be accessed by entering www.google.com into the address bar of web browser. Try it once. You will like it.
Additionally there is a website called www.codeproject.com where software developers gather to help others in 'specific programming issues'. The questions which can be solved by a simple Google search are ignored so as to not to encourage the user to post more like this.
I hope following these steps you will be easily able to do your application.The condition is only that you will have to read it and understand..cause like magic its not going to be complete in a click.
