I am trying to do printing in C# for the first time. I am working the example at http://msdn.microsoft.com/en-us/library/cfkddyc2(VS.80).aspxHere is the rub. It is not recognizing printDocument1
I am guessing that printDocument1 is an instantition of a provided class, but I odn't know what it is and it si not in the example.
this.printDocument1.PrintPage += new
System.Drawing.Printing.PrintPageEventHandler
(this.printDocument1_PrintPage);
this.button1.Click += new System.EventHandler(this.button1_Click);
private void button1_Click(object sender, System.EventArgs e)
{
PrintDialog printDialog1 = new PrintDialog();
printDialog1.Document = printDocument1;
DialogResult result = printDialog1.ShowDialog();
if (result == DialogResult.OK)
{
printDocument1.Print();
}
}
private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
e.Graphics.FillRectangle(Brushes.Red, new Rectangle(500, 500, 500, 500));
}

using System;
using System.Drawing;
using System.Drawing.Printing;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
PrintDocument pd = new PrintDocument();
pd.PrintPage += pd_PrintPage;
PrintPreviewDialog ppd = new PrintPreviewDialog();
ppd.Document = pd;

}
void pd_PrintPage(object sender, PrintPageEventArgs e)
{
e.Graphics.FillRectangle(Brushes.Red, 100, 100, 100, 100);

Do you get a red rectangle on the PrintPreview? - Marked As Answer byJimGuyer Tuesday, September 22, 2009 3:19 PM

| | JohnWein Tuesday, September 22, 2009 2:04 PM | Jim:
Without having to open Visual Studio, you can guess the class name is PrintDocument. Visual Studio names controls and components by adding a number to its base class.
If you open a form and then go to the toolbox, you should see a PrintDocument toolbox item. It should be at least in the "All Windows Forms" tab.
MCP | | webJose Monday, September 21, 2009 9:44 PM | Find the PrintDocument component in the Toolbox and double-click on it. Your squigglies should go away and the program should compile and run. Unless you need to use PrintDialogEx. | | JohnWein Monday, September 21, 2009 9:50 PM | Alright, I got that figured out, and it does run a page through the printer, but it is not printing my rectangle on the page.
public static void DropDownItem_Print_Click(object ParmObject, EventArgs ParmEventArgs) {
PrintDocument printDocument1 = new PrintDocument();
PrintDialog printDialog1 = new PrintDialog();
printDialog1.Document = printDocument1;
DialogResult result = printDialog1.ShowDialog();
if (result == DialogResult.OK)
{
printDocument1.Print();
}
}
private void printDocument1_PrintPage(object sender,System.Drawing.Printing.PrintPageEventArgs e) {
e.Graphics.FillRectangle(Brushes.Red,
new Rectangle(500, 500, 500, 500));
}
| | JimGuyer Monday, September 21, 2009 9:52 PM | Since it sendsa page through the printer, it's executing the PrintPage event, so there must be something wrong with the FillRectangle statement. Change the rectangle to100,100,100,100. | | JohnWein Monday, September 21, 2009 10:10 PM | You are creating a *new* instance of the PrintDocument class in your Print_Click event handler. Don't. That new instance won't have the PrintPage event handler set. Just delete the line.
