Hi,
I am trying to learn how to use how to print in a windows form. I am
using the components PrintDialog and the PrintDocument. I am
succeding to show the dialog box, and to pass paper from the printer.

Obviously no data is being printed. How do I pass data to the
PrintDocument object and what type of data does it accept.


Can someone help me out, because I am a newbie in such a thing.
Thanks in Advance
 
public class PrintScreen
{
public PrintScreen()
{
//
// TODO: Add constructor logic here
//
}
public PrintScreen(System.Windows.Forms.Form frm)
{
CapturePrintScreen(frm);
System.Drawing.Printing.PrintDocument prtDoc1 = new
System.Drawing.Printing.PrintDocument();
prtDoc1.PrintPage += new
System.Drawing.Printing.PrintPageEventHandler(prtDoc1_PrintPage);
System.Windows.Forms.PageSetupDialog pg = new
System.Windows.Forms.PageSetupDialog();
pg.Document = prtDoc1;
pg.PageSettings.Landscape = true;
prtDoc1.Print();
}
[System.Runtime.InteropServices.DllImport("gdi32.dll")]
public static extern long BitBlt (IntPtr hdcDest, int nXDest, int nYDest,
int nWidth, int nHeight, IntPtr hdcSrc
, int nXSrc, int nYSrc, int dwRop);
private Bitmap memoryImage;

private void CapturePrintScreen(System.Windows.Forms.Form frm)
{
Graphics mygraphics = frm.CreateGraphics();
Size s = frm.Size;
memoryImage = new Bitmap(s.Width, s.Height, mygraphics);
Graphics memoryGraphics = Graphics.FromImage(memoryImage);
IntPtr dc1 = mygraphics.GetHdc();
IntPtr dc2 = memoryGraphics.GetHdc();
BitBlt(dc2, 0, 0, frm.ClientRectangle.Width, frm.ClientRectangle.Height,
dc1, 0, 0, 13369376);
mygraphics.ReleaseHdc(dc1);
memoryGraphics.ReleaseHdc(dc2);
}
private void prtDoc1_PrintPage(object sender,
System.Drawing.Printing.PrintPageEventArgs e)
{
e.Graphics.DrawImage(memoryImage, 0, 0);
}
}

call this class from an event:
new PrintScreen(this)
 
Hi,
I tried the code given, and set the new(this) in a click event of a
button. When I runned the application, the button was printed.

In my application, I am displaying datagrids, which are binded with a
datasource. What I need to print is these datagrids.

How can this be done.
Thanks in Advance

If you won't be stressed by all the .net printing stuff you can give a try
to my report engine :)

You can design your data report or build it at runtime.

See the link in signature
 
A PrintDocument subclass can take any datasource that you want to send
it but you have to write the code to paginate and display that data. I
normally use an XmlDocument to hold my print data but that is because I have
another use for the XML (sending documents between locations).
You could just write some code to utilize the information bound to the
grid and print it as desired.
