doublebuffered exception

Recommended Posts

I'm getting an exception error when setting doublebuffered to true in C#. I'm not sure why it's happening. It says invalid argument exception.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace SimpleGame
    public partial class frmSimpleGame : Form
        private Bitmap m_objDrawingSurface;
        private Graphics objGraphics;
        private SolidBrush solidBrush = new SolidBrush(Color.Black);
        public frmSimpleGame()
            //this.DoubleBuffered = true;

        private void frmSimpleGame_Paint(object sender, PaintEventArgs e)
            e.Graphics.DrawImage(m_objDrawingSurface, 0, 0,

        private void frmSimpleGame_Load(object sender, EventArgs e)
            //this.SetStyle(ControlStyles.AllPaintingInWmPaint, true);
            //this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true);
            m_objDrawingSurface = new Bitmap(this.ClientSize.Width, this.ClientSize.Height,
            objGraphics = Graphics.FromImage(m_objDrawingSurface);

        private void frmSimpleGame_MouseMove(object sender, MouseEventArgs e)

            objGraphics = Graphics.FromImage(m_objDrawingSurface);
            objGraphics.FillEllipse(solidBrush, e.X - 25, e.Y - 25, 50, 50);
            lblX.Text = string.Concat("X:" + (e.X - 25));
            lblY.Text = string.Concat("Y:" + (e.Y - 25));

        private void frmSimpleGame_FormClosed(object sender, FormClosedEventArgs e)

The project works fine if I take out doublebuffered = true. I've tried it in the load event. I've also tried using the setstyle method and it gives the same exception error. Thanks
