         static void Main()
         {
             Application.Run(new Form1());
         }
 
     private void Form1_Load(object sender, System.EventArgs e)
         {
                 }
 
         private void button1_Click(object sender, System.EventArgs e)
         {
 
                         MessageBox.Show ("Hello");
