Explaining Code

Every Button contain a try catch block like this

   try
            {
                System.Diagnostics.Process.Start("wordpad");
            }
            catch (Exception Ex)
            {
                MessageBox.Show("File Not Found \n \n \n" + Ex);
            }
        }

Firstly try block execute and if requesting app exists than it start the process

otherwise catch block is executed that shows a message box "File Not Found"

Screen also contain a MenuStrip contain About and Exit.

By clicking on about .. Author Name is displayed.

By clicking on Exit ..  Application.Exit(); Function calls.
