In my application I'm trying to create a function to print existing PDFs or Doc. How can I do this in C# and provide a mechanism so the user can select a different printer or other properties.
I've looked at the PrintDialog but not sure what file it is attempting to print, if any, b/c the output is always a blank page. Maybe I'm just missing something there.
Any advice, examples or sample code would be great!
The below is my code
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
string printPath =
System.Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
System.IO.StreamReader fileToPrint;
fileToPrint= new System.IO.StreamReader(printPath + @"\myFile.txt");
System.Drawing.Font printFont;
printPDF(e);
printDocument1.Print();
fileToPrint.Close();
}
private void button2_Click(object sender, EventArgs e)
{
//printDoc(e);
}
public void printPDF(object sender ,
System.Drawing.Printing.PrintPageEventArgs e))
{
printFont = new System.Drawing.Font("Arial", 10);
float yPos = 0f;
int count = 0;
float leftMargin = e.MarginBounds.Left;
float topMargin = e.MarginBounds.Top;
string line = null;
float linesPerPage = e.MarginBounds.Height /
printFont.GetHeight(e.Graphics);
while (count < linesPerPage)
{
line = fileToPrint.ReadLine();
if (line == null)
{
break;
}
yPos = topMargin + count * printFont.GetHeight(e.Graphics);
e.Graphics.DrawString(line, printFont, Brushes.Black, leftMargin, yPos,
new StringFormat());
count++;
}
if (line != null)
{
e.HasMorePages = true;
}
fileToPrint.Close();
}
public void printDoc()
{
}
}
}

This has worked in the past:
To print to the default printer, replace
printto
withprint
, and leave off theArguments
line.
