What I want to say SUN (sun) and MS (moon) both are very Important to IT
WORLD (world) but both are now enemies now a days they are making languages
to dominate each other.  This is sure without sun and moon there is no world
like that with out SUN and MS there is no IT WORLD. I pry to god to make both
are good friends they should work for IT PEOPLE.
  
This application has 4 files
shesharp.cs
javasharp.java
comp.bat  //for compel
j.bat
  
In this application I used Inner class for developing panel.
using System.Windows.Forms;
using System.Drawing;
using System.Drawing.Drawing2D;
using System.Diagnostics;
using System;
  
//for mixed background
public void format(object s,PaintEventArgs a)

      Graphics g=CreateGraphics();
      Rectangle rect=new Rectangle(0,0,300,300);

      LinearGradientBrush b=new       LinearGradientBrush(rect,Color.DarkOra
nge,nyc,LinearGradientMode.Vertical);
      g.FillRectangle(b,rect);
    }
//for calling java program
