Please help me. i am not able to Run your code(print windows form sample). the following code giving compile errors that code is regarding print windows form(whatever u have wrote code that code only). using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using System.Drawing.Imaging; using System.Drawing.Printing; namespace Print { public partial class Form1 : Form { public System.IO.Stream streamToPrint; string streamType; private static extern bool BitBlt ( IntPtr hdcDest, // handle to destination DC int nXDest, // x-coord of destination upper-left corner int nYDest, // y-coord of destination upper-left corner int nWidth, // width of destination rectangle int nHeight, // height of destination rectangle IntPtr hdcSrc, // handle to source DC int nXSrc, // x-coordinate of source upper-left corner int nYSrc, // y-coordinate of source upper-left corner System.Int32 dwRop // raster operation code ); private void printDoc_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e) { System.Drawing.Image image = System.Drawing.Image.FromStream; this.streamToPrint; int x = e.MarginBounds.X; int y = e.MarginBounds.Y; int width = image.Width; int height = image.Height; if ((width / e.MarginBounds.Width) > (height / e.MarginBounds.Height)) { width = e.MarginBounds.Width; height = image.Height * e.MarginBounds.Width / image.Width; } else { height = e.MarginBounds.Height; width = image.Width * e.MarginBounds.Height / image.Height; } System.Drawing.Rectangle destRect = new System.Drawing.Rectangle(x, y, width, height); e.Graphics.DrawImage(image, destRect, 0, 0, image.Width, image.Height, System.Drawing.GraphicsUnit.Pixel); } [System.Runtime.InteropServices.DllImportAttribute("gdi32.dll")] public void StartPrint(Stream streamToPrint, string streamType) { this.printDoc.PrintPage += new PrintPageEventHandler(printDoc_PrintPage); this.streamToPrint = streamToPrint; this.streamType = streamType; System.Windows.Forms.PrintDialog PrintDialog1 = new PrintDialog(); PrintDialog1.AllowSomePages = true; PrintDialog1.ShowHelp = true; PrintDialog1.Document = printDoc; DialogResult result = PrintDialog1.ShowDialog(); if (result == DialogResult.OK) { printDoc.Print(); //docToPrint.Print(); } } public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { } private void button1_Click(object sender, EventArgs e) { Graphics g1 = this.CreateGraphics(); Image MyImage = new Bitmap(this.ClientRectangle.Width, this.ClientRectangle.Height, g1); Graphics g2 = Graphics.FromImage(MyImage); IntPtr dc1 = g1.GetHdc(); IntPtr dc2 = g2.GetHdc(); BitBlt(dc2, 0, 0, this.ClientRectangle.Width, this.ClientRectangle.Height, dc1, 0, 0, 13369376); g1.ReleaseHdc(dc1); g2.ReleaseHdc(dc2); MyImage.Save(@"c:\PrintPage.jpg", ImageFormat.Jpeg); FileStream fileStream = new FileStream(@"c:\PrintPage.jpg", FileMode.Open, FileAccess.Read); StartPrint(fileStream, "Image"); fileStream.Close(); if (System.IO.File.Exists(@"c:\PrintPage.jpg")) { System.IO.File.Delete(@"c:\PrintPage.jpg"); } } } } i am waiting for u r code. thanks and regards Sreenivas

hi,

sorry for the late response.can u give me the details of the error?

My code as such does'nt give me error.which version of Visual studio do u use?

Regards,

Rajalakshmi

In btnPrint_Click() we can't assume that C: is writable by the current user and actually we don't *really* need any temp file, u could simple use a MemoryStream as follows : private void btnPrint_Click(object sender, EventArgs e) { // .... Some Code Omitted ... MemoryStream ms = new MemoryStream(); MyImage.Save(ms, ImageFormat.Jpeg); StartPrint(ms, "Image"); ms.Close(); }

hi i m salman and i have used ur code for printing but unable to import the Gdi32.dll file in my code, i have downloaded the gdi32.dll from internet. In visual studio when i add reference to it, it do not allow me to add the reference and generates an error. The error z "A reference to 'C:\documents and settings\abc\my documents\Visual Studio 2005\projects\print\print\Gdi32.dll' could not be added. Please make sure that the file is accessible, and that it is a valid assembly or COM component". so plz guide me how to import this Dll to my project.
