Need to print my "panel"...

Hi,

I read these code and I need to print my panel but I receive this message: Parameter is not valid. The point of my bugg is on this line: Bmp = new Bitmap("c:\desert.jpg")

The path is correct but I am not sure if something is not wrong:

using System;

using System.Drawing;

using System.Drawing.Printing;

using System.Windows.Forms;

namespace WindowsFormsApplication1

{

public partial class Form1 : Form

{

private MyPanel IPanel;

private Button[] Btns = new Button[2];

public Form1()

{

InitializeComponent();

IPanel = new MyPanel(this);

this.StartPosition = FormStartPosition.Manual;

IPanel.Location = new Point(10, 10);

this.ClientSize = new Size(IPanel.Width + 20, IPanel.Height + 100);

string[] BtnsTxt = {"Print", "Preview"};

for (int I = 0; I < Btns.Length; I++)

{

Btns[I] = new Button();

Btns[I].Text = BtnsTxt[I];

Btns[I].Top = IPanel.Bottom + 10;

Btns[I].Left = this.ClientSize.Width - (I + 1) * (Btns[0].Width + 20);

Btns[I].Click += ff_Click;

Btns[I].Parent = this;

}

private void ff_Click(object sender, EventArgs e)

{

if (((Button)sender).Text == "Preview")

{

IPanel.Preview();

}

else

{

IPanel.Print();

}

internal class MyPanel : Panel

{

internal Bitmap Bmp;

internal string[] T = { "RHC-IN-000089", "MUHOZI DAVID", "08-Oct-1991", "MALE", "PC069663" };

private PrintPreviewDialog PPDlg = new PrintPreviewDialog();

private PrintDocument PD = new PrintDocument();

public MyPanel(Form Parent)

{

this.Size = new Size(480, 340);

this.BackColor = Color.White;

Bmp = new Bitmap("desert.jpg"); //the bugg is pointed here

Bmp = Bmp.Clone(new Rectangle(85, 140, 80, 120), Bmp.PixelFormat);

this.Parent = Parent;

PD.OriginAtMargins = true;

PD.DefaultPageSettings.Margins = new Margins(0, 0, 0, 0);

PD.DefaultPageSettings.PaperSize = new PaperSize("ICard", 480, 340);

PPDlg.Document = PD;

PD.PrintPage += PD_PrintPage;

}

public void Preview()

{

PPDlg.ShowDialog();

}

public void Print()

{

PD.Print();

}

protected override void OnPaint(System.Windows.Forms.PaintEventArgs e)

{

base.OnPaint(e);

DrawCard(e.Graphics);

}

public void PD_PrintPage(object sender, PrintPageEventArgs e)

{

DrawCard(e.Graphics);

}

public void DrawCard(Graphics G)

{

int X = 260;

int Y = 130;

G.DrawImage(Bmp, 75, 130);

for (int I = 0; I < T.Length; I++)

{

G.DrawString(T[I], this.Font, Brushes.Black, X, Y);

X = 200;

Y += 30;

}
