I am developing an application in which I am sending data in string format to the server. Below is my code. It is working fine. But now my question is how can I send whole .txt file and .doc file to the server. In my GUI I have to provide path of user choice. Means user has to choose the path of file that he/she wants to send...Please help me to solve my problem...Thank you...
