c# save pdf file to specific path - c#

I am using Visual Studio 2012. I am converting an aspx page into a PDF file.
It works fine...
the code is like this
string attachment = "attachment; filename=" + FileName + ".pdf";
Response.ClearContent();
Response.AddHeader("content-disposition", attachment);
Response.ContentType = "application/pdf";
StringWriter s_tw = new StringWriter();
HtmlTextWriter h_textw = new HtmlTextWriter(s_tw);
h_textw.AddStyleAttribute("font-size", "7pt");
h_textw.AddStyleAttribute("color", "Black");
pnlPrincipal.RenderControl(h_textw);//Name of the Panel
Document doc = new Document();
doc = new Document(PageSize.A4, 5, 5, 15, 5);
FontFactory.GetFont("Verdana", 80, iTextSharp.text.BaseColor.RED);
PdfWriter.GetInstance(doc, Response.OutputStream);
doc.Open();
StringReader s_tr = new StringReader(s_tw.ToString());
HTMLWorker html_worker = new HTMLWorker(doc);
html_worker.Parse(s_tr);
doc.Close();
Response.Write( doc);
The problem I am facing is that it is saved in c:/Users/Download folder.
I want to save the file in an specific folder.
Where can I specified that?
Thanks

You can write a document with
string folder = #"C:\Temp\";
string fileName = "mydocument.txt";
string fullPath = folder + fileName;
string data = "My string to write in a document";
File.WriteAllLines(fullPath, data);
// Read & print in console
string readText = File.ReadAllText(fullPath);
Console.WriteLine(readText);

Finally I found the way...
Instead of using Response I have to use FileStream
System.IO.FileStream fs = new FileStream(Server.MapPath("PDFDIR") + "\\" + otd.NumeroOTD.ToString() + ".pdf", FileMode.Create);
StringWriter s_tw = new StringWriter();
HtmlTextWriter h_textw = new HtmlTextWriter(s_tw);
h_textw.AddStyleAttribute("font-size", "7pt");
h_textw.AddStyleAttribute("color", "Black");
pnlPrincipal.RenderControl(h_textw);//Name of the Panel
// Create an instance of the document class which represents the PDF document itself.
Document document = new Document(PageSize.A4, 25, 25, 30, 30);
// Create an instance to the PDF file by creating an instance of the PDF
// Writer class using the document and the filestrem in the constructor.
FontFactory.GetFont("Verdana", 80, iTextSharp.text.BaseColor.RED);
PdfWriter writer = PdfWriter.GetInstance(document, fs);
document.AddCreator("Sample application using iTextSharp");
document.AddSubject("Document subject - Describing the steps creating a PDF document");
document.AddTitle("The document title - PDF creation using iTextSharp");
// Open the document to enable you to write to the document
document.Open();
// Add a simple and wellknown phrase to the document in a flow layout manner
// document.Add(new Paragraph("Hello World!"));
StringReader s_tr = new StringReader(s_tw.ToString());
HTMLWorker html_worker = new HTMLWorker(document);
html_worker.Parse(s_tr);
// Close the document
document.Close();
// Close the writer instance
writer.Close();
// Always close open filehandles explicity
fs.Close();

assigning user defined name while downloading the pdf using itextsharp

when I am downloading a pdf the file name is coming as "Response" while saving in the particular location and if I am changing the name of the file then it is coming as the image below.
and when I am selecting the same default name then its coming perfect.
is it possible it set the name as user defined.
Code what I am using is:
HttpContext.Current.Response.ContentType = "application/pdf";
HttpContext.Current.Response.AddHeader("content-disposition", "attachment;filename=filename.pdf");
HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter w = new HtmlTextWriter(sw);
Document doc = new Document(PageSize.A4, 10f, 10f, 100f, 0f);
string pdfFilePath = HttpContext.Current.Server.MapPath(".") + "/PDFFiles";
HTMLWorker htmlparser = new HTMLWorker(doc);
PdfWriter.GetInstance(doc, HttpContext.Current.Response.OutputStream);
doc.Open();
try
{
doc.Add(new Paragraph("Test PDF Download"));
doc.Close();
HttpContext.Current.Response.Write(doc);
HttpContext.Current.Response.End();
}
catch (Exception ex)
{ }
finally
{
doc.Close();
}

create multiple page pdf from asp.net mvc?

I was trying to create a pdf dynamically and send it by attaching in the mail.
This is my code and it works perfectly for me.
public ActionResult sendmail()
{
MemoryStream ms = new MemoryStream();
Document doc = new Document(PageSize.A4, 10f, 10f, 100f, 0.0f);
PdfWriter writer = PdfWriter.GetInstance(doc, ms);
doc.Open(); //open doc for editing
doc.Add(new Paragraph("First Paragraph"));
doc.Add(new Paragraph("Second Paragraph"));
writer.CloseStream = false; //important
doc.Close(); //build the doc.
ms.Position = 0;
SmtpClient smtpClient = new SmtpClient();
smtpClient.Host = "provider.com";
smtpClient.Credentials = new NetworkCredential("credentialmailid", "password");
MailMessage mailMessage = new MailMessage()
{
From = new MailAddress("from#gmail.com")
};
mailMessage.To.Add(new MailAddress("to#gmail.com"));
mailMessage.Subject = "Pdf attached";
mailMessage.Attachments.Add(new Attachment(ms, "pdfname.pdf"));
smtpClient.Send(mailMessage);
return RedirectToAction("index");
}
Now my issue is : Document that I have to send is a purchase confirmation . it will have 3 pages. Many headings and styles will be there in it.
also some values I have to pass dynamically like who purchased it and date like wise a lot datas should pass dynamically
How to do this? I thought to create an Html of pdf file to be send and use something like this add parameters dynamically...
string mailpath = Server.MapPath("~/Mail/HtmlOF_pdfToSend.html");
string mailbody = System.IO.File.ReadAllText(mailpath);
mailbody = mailbody.Replace("##CompanyName", "Bhavin Merchant");
mailbody = mailbody.Replace("##BusinessType", "Bhavin business");
Fist You have to add iTextSharp dll then u have to add some packages :
using iTextSharp.text;
using iTextSharp.text.pdf;
using iTextSharp.text.html;
using iTextSharp.text.xml;
using iTextSharp.text.html.simpleparser;
then as per your question. you want to pass dynamically values so i post some syntax as example :
// Create a Document object
var document = new Document(PageSize.A4, 50, 50, 25, 25);
var output = new MemoryStream();
// Create a new PdfWriter object, specifying the output stream
var writer = PdfWriter.GetInstance(document, output);
// Open the Document for writing
document.Open();
Suppose you have header in your pdf documnet so syntax will be :
var logo = iTextSharp.text.Image.GetInstance(Server.MapPath("~/images/it.jpg"));
logo.SetAbsolutePosition(300, 750);
document.Add(logo);
If you want to add phrase:
Phrase titl = new Phrase("\nE-Ticket\n");
titl.Font.SetStyle(Font.BOLD);
document.Add(titl);
Add lines :
Phrase titl1 = new Phrase("--------------------------------------------------------------------------------------\n\n");
titl1.Font.SetStyle(Font.BOLD);
document.Add(titl1);
Change the style of text :
Here you can change the font style & color.
Phrase title = new Phrase("Booking Date-" + txtDate1.Text + "\n");
title.Font.SetStyle(Font.BOLD);
document.Add(title);
If you want to add pdf table:-dt is data table.
PdfPTable UserInfoTable = new PdfPTable(dt.Columns.Count);
PdfPRow row = null;
UserInfoTable.AddCell(--add cell----);
document.Add(UserInfoTable);
Close the Document - this saves the document contents to the output stream
document.Close();
Response.ContentType = "application/pdf";
Response.AddHeader("Content-Disposition", string.Format("attachment;filename=Receipt-{0}.pdf", "hello"));
Response.BinaryWrite(output.ToArray())
Here I paste some example code as your question.
You can add more pages to the document like this:
doc.Open(); //open doc for editing
doc.Add(new Paragraph("First Paragraph"));
doc.newPage();
doc.add(new Paragraph("This is a new page =)"));

Html to PDf conversion unicode character rendering as empty

I am converting some html into pdf using itext sharp. First i have filled out some html string into String Writer then using below mentioned code to converty byte array into pdf
Problem is unicode character [arabic in specific] is rendering empty.
My code is
var sw = new StringWriter();
sw = GetHtmlContent();// here i fetch html
byte[] data;
using (var sr = new StringReader(sw.ToString()))
{
using (var ms = new MemoryStream())
{
using (var pdfDoc = new Document())
{
//Bind a parser to our PDF document
using (var htmlparser = new HTMLWorker(pdfDoc))
{
//Bind the writer to our document and our final stream
using (var w = PdfWriter.GetInstance(pdfDoc, ms))
{
pdfDoc.Open();
//Parse the HTML directly into the document
htmlparser.Parse(sr);
pdfDoc.Close();
//Grab the bytes from the stream before closing it
data = ms.ToArray();
}
}
}
}
}
Response.Buffer = false;
Response.Clear();
Response.ClearContent();
Response.ClearHeaders();
Response.ContentType = "application/pdf";
Response.AddHeader("Content-Disposition", "attachment; filename=Test.pdf");
Response.BinaryWrite(data);
Response.End();
Please help me what's wrong in it
Check below steps to display unicode characters in converting Html to Pdf
Create a HTMLWorker
Register a unicode font and assign it
Create a style sheet and set the encoding to Identity-H
Assign the style sheet to the html parser
Check below code
TextReader reader = new StringReader(html);
Document document = new Document(PageSize.A4, 30, 30, 30, 30);
PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(FileName, FileMode.Create));
HTMLWorker worker = new HTMLWorker(document);
document.Open();
FontFactory.Register("C:\\Windows\\Fonts\\ARIALUNI.TTF", "arial unicode ms");
iTextSharp.text.html.simpleparser.StyleSheet ST = new iTextSharp.text.html.simpleparser.StyleSheet();
ST.LoadTagStyle("body", "encoding", "Identity-H");
worker.Style = ST;
worker.StartDocument();

Export div content to pdf format

I used the following code to export div content to pdf format using itextsharp
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=Panel.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
Panel1.RenderControl(hw);
StringReader sr = new StringReader(sw.ToString());
// Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 100f, 0f);
Document pdfDoc = new Document(new Rectangle(1000f, 1000f));
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End();
it shows the following error
Could not find a part of the path 'C:\Program Files\Common Files\Microsoft Shared\DevServer\10.0\Images\logo.png'.`
if i hide the logo in desin then it exported to pdf but the alignment are missing. how to correct it.The page i need to export is follows
In order to export the content to any pdf file, you need to follow the basic conventions of pdf file, those are given in the appendix G of the following pdf reference,
http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/pdf_reference_1-7.pdf
Firstly install class in Nuget console: Install-Package itextsharp.xmlworker
Then add namespace: using iTextSharp.tool.xml;
Response.ContentType = "application/pdf";
//string pdf;
// pdf = Convert.ToInt32(hidTablEmpCode.ToString()).ToString() + ".Pdf";
Response.AddHeader("content-disposition", "attachment;filename=Panel.pdf");
//Response.AddHeader("content-disposition", "attachment;filename=Panel.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
// var example_html = #"<p>This is <span class="" headline="" style="">some</span> sample text<span style="">!!!</span></p>";
StringReader sr = new StringReader(lblMessageDetail.Text);
Document pdfDoc = new Document(PageSize.A4, 50f, 50f, 50f, 50f);
var writer = PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
for (int i = 0; i < 5; i++)
{
string imageFilePath2 = Server.MapPath(".") + "/images/GraphicNew.jpg";
iTextSharp.text.Image jpg3 = iTextSharp.text.Image.GetInstance(imageFilePath2);
jpg3.Alignment = iTextSharp.text.Image.UNDERLYING;
jpg3.ScaleToFit(3530, 835);
jpg3.SetAbsolutePosition(0, 0);
pdfDoc.Add(jpg3);
}
XMLWorkerHelper.GetInstance().ParseXHtml(writer, pdfDoc, sr);
string imageFilePath = Server.MapPath(".") + "/Bimages/ns5.png";
iTextSharp.text.Image jpg = iTextSharp.text.Image.GetInstance(imageFilePath);
GetEmp();
string imageURLS = Server.MapPath("~/Emp/Document/") + hidTablEmpCode.Value + "/" + hidSign.Value.ToString();
iTextSharp.text.Image jpg2 = iTextSharp.text.Image.GetInstance(imageURLS);
jpg2.ScaleToFit(100, 50);
jpg2.SetAbsolutePosition(370, 530);
jpg2.Alignment = Element.ALIGN_LEFT;
pdfDoc.Add(jpg2);
jpg.Alignment = iTextSharp.text.Image.ALIGN_LEFT;
jpg.ScaleToFit(100, 50);
jpg.SetAbsolutePosition(50, 735);
pdfDoc.Add(jpg);
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End();

Showing Nothing in created PDF using iTextSharp?

i am trying to export my HTML page to PDF using iTextSharp lib. firstly i am trying to print table which is in my Aspx page.PDF is created successfully but there nothing in PDF.
i am using this code below :
protected void btnExportToPdf_Click(object sender, EventArgs e)
{
btnExportToPdf.Visible = false;
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=TestPage.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
exportTable.RenderControl(hw);
//this.Page.RenderControl(hw);
StringReader sr = new StringReader(sw.ToString());
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 100f, 0f);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End(); }
Now I'm not too seasoned, but the problem to me looks like you are never actually writing the strings to the file. I see a few different string objects you initialize, and I see you adding the HTML to it, but I never see you actually write them to the PDF. This is my usual process for parsing HTML to PDF, maybe you can look at it, and see what you are missing.
System.Text.StringBuilder store = new System.Text.StringBuilder();
string line;
while ((line = htmlReader.ReadLine()) != null)
{
store.Append(line + Environment.NewLine);
}
string html = store.ToString();
FileStream stream = new FileStream(newFileName, FileMode.Create, FileAccess.Write);
Document document = new Document(PageSize.LETTER, 15, 15, 35, 25);
PdfWriter writer = PdfWriter.GetInstance(document, stream);
document.Open();
System.Collections.Generic.List<IElement> htmlarraylist = new List<IElement>(HTMLWorker.ParseToList(new StringReader(html), new StyleSheet()));
foreach (IElement element in htmlarraylist)
{
document.Add(element);
}
document.Close();
That was what jumped out to me at least, was the fact that it doesn't look like you actually write the generated text to the PDF. I hope this helps.
