Continously update image on another form

I rehashed the code to use a double buffered panel
Have a look at the differences, the main one being DoubleBufferPanel class that I added
Once that was done ,there was a DoubleBufferPanel created in the toolbox which I then replaced panelforimage

Thanks a lot. It is working perfectly.

Form1.cs:
Form1_OnLoad()
{
Form form2 = new Form2(); //Sligthly modified code then the previous approach
form2.Show();
}

private void panelforImage_MouseMove(object sender, MouseEventArgs e)
        {
            using (Graphics g = Graphics.FromImage(bitmaptodisplayzoom))  //bitmaptodisplay zoom size is als0 300x 300
                {
                    //new Point(319, 64), new Point(419,214)
                    g.CopyFromScreen(new Point(e.X, e.Y), new Point(0, 0), new Size(300, 300));
                }

form2.toset = bitmaptodisplayzoom;
bitmaptodisplayzoom.Dispose();

}
Form2.cs:
public Image toset;
private void zoomwindow_Load(object sender, EventArgs e)
        {
            Thread th = new Thread(displayimage);
            th.Start();
                       
        }
public void displayimage()
        {
            try
            {

                while (true)
                {
                    Thread.Sleep(1000);
                 
                    pictureBoxZoomView.Image = toset;
                }
                       
                   
              
            }
            catch (Exception ezoom)
            {
             
            }
         
                    
        }
