I did a windows form using C# about Conversion File to PDF using Microsoft Print to PDF. I already referred to many coding and one of it is from Unable to open the PDF, which was generated using print to pdf code written in C#.
Here below is what I made some little changes.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Drawing.Printing;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
//using Microsoft.Office.Interop.Word;
//using Microsoft.Office.Interop.Excel;
//using Spire.Pdf;
namespace fileConversion
{
public partial class Form1 : Form
{
private System.Drawing.Font printFont;
private StreamReader streamToPrint;
public Form1()
{
InitializeComponent();
}
private void selectFile_Click(object sender, EventArgs e)
{
if (openFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
label1.Text = openFileDialog1.FileName; //text label1 tu pegang file name yang kita select
}
}
private void convertFile_Click(object sender, EventArgs e)
{
string FileName = label1.Text;
// the directory to store the output.
//string directoryPath = System.IO.Path.GetDirectoryName(FileName);
// initialize PrintDocument object
PrintDocument doc = new PrintDocument()
{
PrinterSettings = new PrinterSettings()
{
// set the printer to 'Microsoft Print to PDF'
PrinterName = "Microsoft Print to PDF",
// set the filename to whatever you like (full path)
PrintFileName = System.IO.Path.GetFullPath(@"" + FileName + ".pdf"),
// tell the object this document will print to file
PrintToFile = true,
}
};
doc.PrintPage += new PrintPageEventHandler(this.pd_PrintPage);
doc.Print();
}
private void pd_PrintPage(object sender, PrintPageEventArgs ev)
{
float linesPerPage = 0;
float yPos = 0;
int count = 0;
float leftMargin = ev.MarginBounds.Left;
float topMargin = ev.MarginBounds.Top;
string line = File.ReadAllText(label1.Text);
// Calculate the number of lines per page.
linesPerPage = ev.MarginBounds.Height /
printFont.GetHeight(ev.Graphics);
// Print each line of the file.
while ((line = streamToPrint.ReadLine()) != null)
{
yPos = topMargin + (count *
printFont.GetHeight(ev.Graphics));
ev.Graphics.DrawString(line, printFont, Brushes.Black,
leftMargin, yPos, new StringFormat());
count++;
}
// If more lines exist, print another page.
if (line != null)
ev.HasMorePages = true;
else
ev.HasMorePages = false;
}
}
}
However, based on what I did (above code), I successfully convert the file to pdf, but it is unable to open. Before I changed above code, I did:
private void convertFile_Click(object sender, EventArgs e)
{
string FileName = label1.Text;
// the directory to store the output.
//string directoryPath = System.IO.Path.GetDirectoryName(FileName);
// initialize PrintDocument object
PrintDocument doc = new PrintDocument()
{
PrinterSettings = new PrinterSettings()
{
// set the printer to 'Microsoft Print to PDF'
PrinterName = "Microsoft Print to PDF",
// set the filename to whatever you like (full path)
PrintFileName = System.IO.Path.GetFullPath(@"" + FileName + ".pdf"),
// tell the object this document will print to file
PrintToFile = true,
}
};
doc.PrintPage += new PrintPageEventHandler(this.pd_PrintPage);
doc.Print();
}
Though the conversion from file to pdf are success, but the contents in the pdf file are not displayed. there's only blank pdf file.
and this is my new code after corrected.

}
if (result != DialogResult.Cancel) // in case they canceled the save as dialog
{
doc.PrintPage += new PrintPageEventHandler(pd_PrintPage);
doc.Print();
}
}
}
finally
{
streamToPrint.Close();
}
}
private static void pd_PrintPage(object sender, PrintPageEventArgs ev)
{
float linesPerPage = 0;
float yPos = 0;
int count = 0;
float leftMargin = ev.MarginBounds.Left;
float topMargin = ev.MarginBounds.Top;
String line = null;
// Calculate the number of lines per page.
linesPerPage = ev.MarginBounds.Height /
printFont.GetHeight(ev.Graphics);
// Iterate over the file, printing each line.
while (count < linesPerPage &&
((line = streamToPrint.ReadLine()) != null))
{
yPos = topMargin + (count *
printFont.GetHeight(ev.Graphics));
ev.Graphics.DrawString(line, printFont, Brushes.Black,
leftMargin, yPos, new StringFormat());
count++;
}
// If more lines exist, print another page.
if (line != null)
ev.HasMorePages = true;
else
ev.HasMorePages = false;
}
}
}
