Hi I have a C# code snippet which would assign title to the pdf file.But I am trying to do the same for each and every pdf files in a directory.Can any one help me...?
Following is the code snippet
"
PdfReader pdfReader = new PdfReader(filePath);
using (FileStream fileStream = new FileStream(newFilePath, FileMode.Create, FileAccess.Write))
{
string title = pdfReader.Info["Title"] as string;
Trace.WriteLine("Existing title: " + title);
PdfStamper pdfStamper = new PdfStamper(pdfReader, fileStream);
Hashtable newInfo = pdfReader.Info;
newInfo["Title"] = "New title";
pdfStamper.MoreInfo = newInfo;
pdfReader.Close();
pdfStamper.Close();
}
"
Try this code, hope that works for you...

Is there any way to create a text file using a name that comes from data entered in a form?
string path = #"E:\AppServ\**Example**.txt";
if (!File.Exists(path))
{
File.Create(path);
}
**Example** being the part taken from user inputted data.
Similar to this Console.Writeline("{0}", userData);

None of these open source projects have good documentation OR do not work with VS 2012.
Does anyone have a recommended solution or can show me the documentation?

You can always just create an html page and then convert that to pdf using wkhtmltopdf. This has the benefit of you not having to construct the pdf with a library such as iText. You just make a text file (html) and then pass it to the wkhtmltopdf executable.
See Calling wkhtmltopdf to generate PDF from HTML for more info.
I have generated a pdf file with password protection by using the following code:
using (Stream input = new FileStream(InputFile, FileMode.Open, FileAccess.Read, FileShare.Read))
{
using (Stream output = new FileStream(OutputFile, FileMode.Create, FileAccess.Write, FileShare.None))
{
PdfReader reader = new PdfReader(input);
PdfEncryptor.Encrypt(reader, output, true, strDob, "secret", PdfWriter.ALLOW_SCREENREADERS);
}
}
I want to remove the password for the PDF file generated using the above code based on my certain condtions through code.
string WorkingFolder = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
string InputFile = Path.Combine(WorkingFolder, "test.pdf");
string OutputFile = Path.Combine(WorkingFolder, "test_dec.pdf");//will be created automatically
//You must provide owner password but not the user password .
private void DecryptFile(string inputFile, string outputFile)
{
string password = #"secret"; // Your Key Here
try
{
PdfReader reader = new PdfReader(inputFile, new System.Text.ASCIIEncoding().GetBytes(password));
using (MemoryStream memoryStream = new MemoryStream())
{
PdfStamper stamper = new PdfStamper(reader, memoryStream);
stamper.Close();
reader.Close();
File.WriteAllBytes(outputFile, memoryStream.ToArray());
}
}
catch (Exception err)

I created a pdf and added a metadata into it and also encrypted it uisng iTextsharp library.
Now I want to remove the encryption from the pdf. I successfully did so using iTextSharp but was not able to remove the metadata that I added.
Can anyone please giude me how can I remove the metadata. Its urgent.
Thanks.
When removing meta data it is easiest to work directly with the PdfReader object. Once you do that you can write that back to disk. The code below is a full working C# 2010 WinForms application targeting iTextSharp 5.1.2.0. It first creates a PDF with some meta data, then it modifies an in-memory version of the PDF using a PdfReader, and finally writes the changes to disk. See the code for additional comments.
using System;
using System.Collections.Generic;
using System.IO;
using System.Windows.Forms;
using iTextSharp.text;
using iTextSharp.text.pdf;
namespace WindowsFormsApplication1 {
public partial class Form1 : Form {

InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e) {
//File with meta data added
string InputFile = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "Test.pdf");
//File with meta data removed
string OutputFile = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "Output.pdf");
//Create a file with meta data, nothing special here
using (FileStream FS = new FileStream(InputFile, FileMode.Create, FileAccess.Write, FileShare.None)) {
using (Document Doc = new Document(PageSize.LETTER)) {
using (PdfWriter writer = PdfWriter.GetInstance(Doc, FS)) {
Doc.Open();
Doc.Add(new Paragraph("Test"));
//Add a standard header
Doc.AddTitle("This is a test");
//Add a custom header
Doc.AddHeader("Test Header", "This is also a test");
Doc.Close();
}
}
}
//Read our newly created file
PdfReader R = new PdfReader(InputFile);
//Loop through each piece of meta data and remove it
foreach (KeyValuePair<string, string> KV in R.Info) {
R.Info.Remove(KV.Key);
}
//The code above modifies an in-memory representation of the PDF, we need to write these changes to disk now
using (FileStream FS = new FileStream(OutputFile, FileMode.Create, FileAccess.Write, FileShare.None)) {
using (Document Doc = new Document()) {
//Use the PdfCopy object to copy each page
using (PdfCopy writer = new PdfCopy(Doc, FS)) {
Doc.Open();
//Loop through each page
for (int i = 1; i <= R.NumberOfPages; i++) {
//Add it to the new document
writer.AddPage(writer.GetImportedPage(R, i));
}
Doc.Close();
}
}
}
this.Close();
}
}

I have a requirement to generate invoice reports in PDF using some predefined company templates. I am able to create/generate SINGLE PAGE PDF reports using iTextSharp.
Problem: The problem comes when the invoice statement spans MULTIPLE PAGES. I am not able to extend the report(invoice statement) to next(2nd) page. If all the data can not be accommodated on one page it should be written on 2nd page, while still using the company template.
The template is present at following path:
HostingEnvironment.MapPath("~/Content/InvoiceTemplate/invoiceTemplate.pdf")
I am using iTextSharp library to create documents. Below is the code used to generate the PDF:
public class pdfStatementController : Controller {
Models.DYNAMICS_EXTEntities _db = new Models.DYNAMICS_EXTEntities();
//
// GET: /pdfStatement/
public ActionResult SendPdfStatement(string InvoiceNumber) {
try {
InvoiceNumber = InvoiceNumber.Trim();
ObjectParameter[] parameters = new ObjectParameter[1];
parameters[0] = new ObjectParameter("InvoiceNumber", InvoiceNumber);
List<Models.Statement> statementList = new List<Models.Statement>();
statementList = _db.ExecuteFunction<Models.Statement>("uspInvoiceStatement", parameters).ToList<Models.Statement>();
pdfStatementController.WriteInTemplate(statementList);
return RedirectToAction("Invoice", "Invoice", new { id = statementList.FirstOrDefault().Customer_ID.ToString().Trim() });
} catch (Exception e) {
return View("Error");
}
}
public static void WriteInTemplate(List<Models.Statement> statementList) {
string invoiceNumber = statementList.FirstOrDefault().Invoice.ToString().Trim();
string month = null;
string day = null;
string year = null;
PdfReader pdfReader = new PdfReader(
HostingEnvironment.MapPath(
"~/Content/InvoiceTemplate/invoiceTemplate.pdf"));
FileStream fileStream = new FileStream(
HostingEnvironment.MapPath(
"~/Content/reports/" + invoiceNumber + ".pdf"),
FileMode.Create);
PdfStamper pdfStamper = new PdfStamper(pdfReader, fileStream);
AcroFields pdfFields = pdfStamper.AcroFields;
pdfFields.SetField("BillToCompany", statementList.FirstOrDefault().BillToCompany.ToString().Trim().ToUpper());
pdfFields.SetField("BillToContact", statementList.FirstOrDefault().BillToContact.ToString().Trim().ToUpper());
pdfFields.SetField("CustomerId", statementList.FirstOrDefault().Customer_ID);
pdfFields.SetField("InvoiceNumber", statementList.FirstOrDefault().Invoice.ToString().Trim());
pdfFields.SetField("JobNumber", statementList.FirstOrDefault().JobNumber.ToString().Trim());
pdfFields.SetField("Caller", statementList.FirstOrDefault().Caller.ToString().Trim());
pdfStamper.FormFlattening = true; // generate a flat PDF
pdfStamper.Close();
pdfReader.Close();
}
}
Your code looks good and is only missing a couple of intermediate steps.
Since you're using the same PDF template for every page (when two or more pages need to be generated), instead of using a PdfStamper to add content directly to the Document, you use a PdfSmartCopy or PdfCopy object.
The PdfStamper is still needed. However, in this case it's used to create an in-memory (single) page filled with data as you as you iterate over your Models.Statement collection.
In other words, PdfSmartCopy/PdfCopy maintains your statements as a whole, (total pages) and PdfStamper is used as a buffer that adds your individual statements page-by-page to your PDF. Here's a simple working example HTTP hander (.ashx):
<%# WebHandler Language="C#" Class="copyFillTemplate" %>
using System;
using System.Collections.Generic;
using System.IO;
using System.Web;
using iTextSharp.text;
using iTextSharp.text.pdf;
public class copyFillTemplate : IHttpHandler {
public void ProcessRequest (HttpContext context) {
HttpServerUtility Server = context.Server;
HttpResponse Response = context.Response;
Response.ContentType = "application/pdf";
// template used to test __this__ example;
// replace with __your__ PDF template
string pdfTemplatePath = Server.MapPath(
"~/app_data/template.pdf"
);
// this example's test data; replace with __your__ data collection
List<Statement> statementList = Statement.GetStatements();
// COPY FROM HERE
using (Document document = new Document()) {
// PdfSmartCopy reduces PDF file size by reusing parts
// of the PDF template, but uses more memory. you can
// replace PdfSmartCopy with PdfCopy if memory is an issue
using (PdfSmartCopy copy = new PdfSmartCopy(
document, Response.OutputStream)
)
{
document.Open();
// used to test this example
int counter = 0;
// generate one page per statement
foreach (Statement statment in statementList) {
++counter;
// replace this with your PDF form template
PdfReader reader = new PdfReader(pdfTemplatePath);
using (var ms = new MemoryStream()) {
using (PdfStamper stamper = new PdfStamper(reader, ms)) {
AcroFields form = stamper.AcroFields;
// replace this with your field data for each page
form.SetField("title", counter.ToString());
stamper.FormFlattening = true;
}
reader = new PdfReader(ms.ToArray());
// add one page at a time; assumes your template is only one page.
// if your template is more than one page you will need to
// call GetImportedPage() for each page in your template
copy.AddPage(copy.GetImportedPage(reader, 1));
}
}
}
// COPY TO HERE
}
}
public bool IsReusable { get { return false; } }
public class Statement {
public string FieldName, FieldValue;
public static List<Statement> GetStatements() {
List<Statement> s = new List<Statement>();
for (int i = 0; i < 5; ++i) {s.Add(new Statement());}
return s;
}
}
}
Hopefully the inline comments help. And you obviously need to remove replace some parts I used to test the example code.
