printing a form in C# as a graphic

Are you trying to get the whole form?...or just the client area?

The whole form and i get errors on
int width = this.Width;// seems to want a double
int height = this.Height;// seems to want a double
and
Bitmap img = new Bitmap(width, height); //wants more signatures

Should be:

            Bitmap img = new Bitmap(this.Size.Width, this.Size.Height);
            this.DrawToBitmap(img, new Rectangle(0, 0, img.Width, img.Height));
            Point p = new Point(100, 100);
            e.Graphics.DrawImage(img, p);

Still getting errors,

       protected void btnPrint_Click(object sender, EventArgs e)
        {
            
            PrintDocument pd = new PrintDocument();
            pd.PrintPage += new PrintPageEventHandler(PrintImage);
            pd.Print();
        }

        void PrintImage(object o, PrintPageEventArgs e)
        {
            int x = SystemInformation.WorkingArea.X;
            int y = SystemInformation.WorkingArea.Y;
            int width = SystemInformation.WorkingArea.Width;
            int height = SystemInformation.WorkingArea.Height;

            System.Drawing.Rectangle bounds = new System.Drawing.Rectangle(x, y, width, height);

            Bitmap img = new Bitmap(this.Width, this.Height);
            this.DrawToBitmap(img, new System.Drawing.Rectangle(0, 0, img.Width, img.Height));
            Point p = new Point(100, 100);
            e.Graphics.DrawImage(img, p);    
        }

        private void DrawToBitmap(Bitmap img, System.Windows.Shapes.Rectangle rectangle)
        {
            throw new NotImplementedException();

down to one error - any idea?

Your code:

           Bitmap img = new Bitmap(this.Width, this.Height)

My code:

           Bitmap img = new Bitmap(this.Size.Width, this.Size.Height);

Does not contain a definition for Size

           
            int x = SystemInformation.WorkingArea.X;
            int y = SystemInformation.WorkingArea.Y;
            //int width = 1920;
            //int height = 768;
            Bitmap img = new Bitmap(1920, 768);
            System.Drawing.Rectangle bounds = new System.Drawing.Rectangle(0, 0, img.Width, img.Height);
            DrawToBitmap(img, bounds);
            System.Drawing.Point p = new System.Drawing.Point(0,0);
            e.Graphics.DrawImage(img, p);
        }

        private void DrawToBitmap(Bitmap img, System.Windows.Shapes.Rectangle bounds)
        {
            img = new Bitmap(img, 1920, 768);
            //throw new NotImplementedException();
        }

   
        private void DrawToBitmap(Bitmap img, System.Drawing.Rectangle bounds)
        {
            img = new Bitmap(img, 1920, 768);
            //throw new NotImplementedException();
        }
Got it to go to the printer but nothing is on the  paper

Sorry...WPF is confusing me here.  =)

Have you tried just casting the doubles to ints?

    Bitmap img = new Bitmap((int)this.Width, (int)this.Height)

sorry parameters not valid -  Iam at my wits end:)

I am not sure if it can be useful for you, but this is a method I use to get the print-screen of the whole screen (you may need to specify window size and absolute position):

private static void CaptureScreen(String FileName)
        {
            try
            {
                using (var screenBmp = new Bitmap((int)SystemParameters.PrimaryScreenWidth,
                                                    (int)SystemParameters.PrimaryScreenHeight,
                                                        System.Drawing.Imaging.PixelFormat.Format32bppArgb))
                {
                    using (var bmpGraphics = Graphics.FromImage(screenBmp))
                    {
                        bmpGraphics.CopyFromScreen(0, 0, 0, 0, screenBmp.Size);
                        BitmapSource bmpSource = Imaging.CreateBitmapSourceFromHBitmap(
                        screenBmp.GetHbitmap(),
                        IntPtr.Zero,
                        Int32Rect.Empty,
                        BitmapSizeOptions.FromEmptyOptions());

                        BitmapEncoder bmpEncoder = null;
                        if (Path.GetExtension(FileName) == "jpg")
                            bmpEncoder = new JpegBitmapEncoder() { QualityLevel = 20 };
                        else
                            bmpEncoder = new PngBitmapEncoder();

                        bmpEncoder.Frames.Add(BitmapFrame.Create(bmpSource));
                        using (FileStream fs = new FileStream(FileName, FileMode.Create))
                            bmpEncoder.Save(fs);
                    }
                }
            }
            catch
            {
            }
        }

Regards.

It still is not working - if anyone has another Idea on how to print this _ I could really use the help  - maybe combine the 2 bitmap capture and printing in WPF

It is interesting. Could you please show us how your code works to do this?
Thank you!

here is the C#

      private void PrintClick(object sender, RoutedEventArgs e)
        {
            System.Windows.Controls.PrintDialog dialog = new System.Windows.Controls.PrintDialog();
            if (dialog.ShowDialog() == true)
            { dialog.PrintVisual(_PrintCanvas, "Quality Control Inspection Instructions"); }
        }

here is canvas tags

  <Canvas x:Name="_PrintCanvas">
        
        <Grid Width="816" MinHeight="500" VerticalAlignment="Top" Margin="0,0,0,0" >
        <Border BorderBrush="Silver" BorderThickness="1" Style="{StaticResource DropShadowStyle}" Background="{StaticResource InfoBackgroundBrush}">
            <StackPanel Orientation="Vertical" Margin="48">
<!-- ALL YOUR CODE HERE FOR THE FORM-->

                            </Grid>
                    <Button Content="Click Here to Print" Width="Auto" Padding="5" Margin="10" HorizontalAlignment="Left" Click="PrintClick" ></Button>
                </StackPanel>
        </Border>
    </Grid>
        </Canvas>
</UserControl>

See - that simple

figured it out myself - thanks for the help though
