Hai Friends..
I Need Some Code  to change the color of the title bar of a form in c# winforms ?
Actually I Tried by Using USER32.dll..its not Changing The Color Of The Title Bar...Its Just Covering The Title Bar With The Give Color

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;

namespace TitleBarColorChange
{
    public partial class Form1 : Form
    {
        [DllImport("user32.dll")]
        static extern int ReleaseDC(IntPtr hWnd, IntPtr hDc);

        [DllImport("User32.dll")]
        private static extern IntPtr GetWindowDC(IntPtr hWnd);

        public Form1()
        {
            InitializeComponent();
        }
        protected override void WndProc(ref Message m)
        {
            base.WndProc(ref m);
            const int WM_NCPAINT = 0x85;
            if (m.Msg == WM_NCPAINT)
            {
                IntPtr hdc = GetWindowDC(m.HWnd);
                if ((int)hdc != 0)
                {
                    Graphics g = Graphics.FromHdc(hdc);
                    g.FillRectangle(Brushes.Green, new Rectangle(0, 0, 4800, 30));
                    g.Flush();
                    ReleaseDC(m.HWnd, hdc);
                }
            }
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            this.BackColor = System.Drawing.Color.MistyRose;
            this.StartPosition = FormStartPosition.CenterScreen;
          
            
        }
    }
}
