Hi all,
Once I started learning C#, really much enjoying it. I faced some problem using GUI. I m trying to draw ellipse as many as possible with mouse moving events, but theres problem....

My code here:

private void Form1_MouseDown(object sender, MouseEventArgs e)
        {
            myRect.Width = 0;
            myRect.Height = 0;
            myRect.X = e.X;
            myRect.Y = e.Y;
        }

private void Form1_MouseMove(object sender, MouseEventArgs e)
        {
            Graphics g = this.CreateGraphics();
            Pen p = new Pen(Color.Red, 2);


            if (e.Button == MouseButtons.Left)
            {
                g.Clear(this.BackColor);

                myRect.Width = e.X - myRect.X;
                myRect.Height = e.Y - myRect.Y;
                g.DrawEllipse(p, myRect);

            }

        }

private void Form1_MouseUp(object sender, MouseEventArgs e)
        {
            Graphics g = this.CreateGraphics();

            Pen p = new Pen(Color.Green,4);

            g.DrawEllipse(p, myRect);
     //       g.Dispose();
        }

If you run this code, it works fine. BUT I cant draw ellipse continually, then only last one remains and previous one is deleted. BUT if I remove
g.Clear(this.BackColor); this line from mouseMove event, then I can draw ellipse as many as possible. But process shows shadow of the drawing which I want to remove. If you run both ways you might understand what Im trying to do.......

Pls help, urgent pls

thanks in advance

Tool? You mean talking about C#? You dont need to work on console if you use C#. You can work with interface which makes everything easy for you. I use Visual Studio . NET 2008, the lastest version. hope this help
