Why does this code write a "corrupt file" that Word cannot open (not even "Open and Repair")?

I'm a newb, feel free talk down to me.
Sorry to be so vague; the code executes and writes a corrupt file. I can't get into the corrupt file to observe any errors/anomolies. The size does look like a sum of the files being merged.
I've googled the snot outta this and can't find anything I can understand how to implement.
The Word error on open is:
The file cannot be open because there are problems with the contents
and
Word found unreadable content, do you want to continue?
When I click Yes I get the first error again & then I'm out.
THe documents have content controls with the same name, but I've modded this to only add 1 doc in an effort to see if dupe content types would be a problem; same corrupt file results.
btw....my ultimate intent is to overwrite the "template" (...Aggregate Report.dotx) in place. But I can't get a valid file saved ANYWHERE, so...... :-/

It looks like you're not calling .Seek() properly on the main memory stream, also you seem to be using that single memory stream for both input and output possibly at the same time. (Maybe it's correct, but it's just very confusing to me when it's mixed mode)
I'm assuming you can't access raw filenames and the filesystem:
using(Stream t = template.OpenBinaryStream())
{
using (WordprocessingDocument myDoc = WordprocessingDocument.Open(t, true))
{
using (XmlWriter writer = XmlWriter.Create(resp.OutputStream))
{
// TODO re-add merge logic here once it works
HttpResponse resp = HttpContext.Current.Response;
resp.ClearContent();
resp.ClearHeaders();
resp.AddHeader("Content-Disposition",
"attachment; filename=Assembled Document.docx");
//resp.ContentEncoding = System.Text.Encoding.UTF8;
resp.ContentType = "application/msword";
// resp.OutputStream.Write(mem.ToArray(), 0, (int)mem.Length);
/* new */ myDoc.MainDocumentPart.Document.WriteTo(writer);
resp.Flush();
resp.Close();
HttpContext.Current.ApplicationInstance.CompleteRequest();
}
}
}
PS - I recommend getting a raw template to output correctly first. Then make one tiny change and see that output before re-adding your merge logic.

How would I write this to a csv file in c#?

I hope someone can help me. I am a beginner at c# and programming in general and I'm trying to complete this program. Basically it looks in an XML file, grabs all of the occurrences of a specific tag and is supposed to write the File Names plus whatever is between any instances of these two tags. So far I've tried TextWriter, StreamWriter, FileStream and some others and nothing doing what I want. I realise this may be a stupid question but I'm a super noob and need help for my particular case. My code is as follows.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
using System.IO;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
var files = from file in Directory.GetFiles("W:\\SRC\\hDefMl\\1.0\\Instrument_Files")
orderby file
ascending
select file;
StringBuilder sb_report = new StringBuilder();
string delimiter = ",";
sb_report.AppendLine(string.Join(delimiter, "Module", "Generator(s)"));
foreach (var file in files)
{
string filename = Path.GetFileNameWithoutExtension(file);
Console.WriteLine("The HDefML file for {0} contains these EEPROM Generators:", filename);
XDocument hdefml = XDocument.Load(file);
var GeneratorNames = from b in hdefml.Descendants("Generators")
select new
{
name = (string)b.Element("GeneratorName")
};
string description;
foreach (var generator in GeneratorNames)
{
Console.WriteLine(" GeneratorName is: {0}", generator.name);
sb_report.AppendLine(string.Join(delimiter, filename,
generator.name));
}
}
}

You should be able to just do something like this, if the string you have built with your string builder is formatted correctly.
static void WriteToCSV(string str, string path)
{
using (Stream stream = File.Create(path))
using (StreamWriter writer = new StreamWriter(stream))
{
writer.WriteLine(str);
}
}

try{
FileStream FS;
StreamWriter SW;
using (FS = new FileStream("HardCodedFileName.csv", FileMode.Append))
{
using (SW = new StreamWriter(FS))
{
foreach (var generator in GeneratorNames)
{
SW.WriteLine(string.Join(delimiter, filename,
generator.name));
}
}
}
}
catch (Exception e){
Console.Writeline(e.ToString());
}

Remove metadata from existing Pdf using iTextsharp

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 {
public Form1() {
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();
}
}
}

Multipage PDF document from predefined template

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.

Though the last answer is a very good one and helped me to solve my problem, i am putting it here to sum up the question.

Loading RTF file with images to FlowDocument in console application

I am creating simple console application where I need to load RTF file to FlowDocument for further work.
I am using this code for loading file to FlowDocument:
// Create OpenFileDialog
Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();
// Set filter for file extension and default file extension
dlg.DefaultExt = ".rtf";
dlg.Filter = "RichText Files (*.rtf)|*.rtf";
// Display OpenFileDialog by calling ShowDialog method
Nullable<bool> result = dlg.ShowDialog();
if (result == true)
{
// Open document
string filename = dlg.FileName;
FlowDocument flowDocument = new FlowDocument();
TextRange textRange = new TextRange(flowDocument.ContentStart, flowDocument.ContentEnd);
using (FileStream fileStream = File.Open(filename, FileMode.Open, FileAccess.Read, FileShare.Read))
{
textRange.Load(fileStream, DataFormats.Rtf);
}
}
If I do this in WPF application and show the document in flowDocumentPageViewer, everything is OK. But if I try to load file in console application, I get exception: Unrecognized structure in data format Rich Text Box, parameter name stream.
And for some reason, this exception appears only, if there is image in document.
Any ideas what's wrong or better how to solve it?
