How to split a pdf and preserve thumbnail labels? - c#

I have a pdf that has some pages that need to be removed based on the (thumbnail) label of the page. So, I am using the the PdfCopy.GetImportedPage(...) method to copy only the wanted pages but found that the thumbnail label (page label) gets removed. The only way I am able to add pagelabels is to use a Writer, but then I can't copy pages. Can someone help me here to setup the right construction ?
public Boolean SplitByList(string povDocument, string povOutputDocument, PageLabelList povPageList)
{
PdfReader lorReader = null;
Document lorDocument = null;
PdfCopy lorPdfCopyProvider = null;
PdfImportedPage lorImportedPage = null;
PdfPageLabels lorLbls = null;
try
{
// Intialize a new PdfReader instance with the contents of the source Pdf file:
lorReader = new PdfReader(povDocument);
lorLbls = new PdfPageLabels();
if (povPageList == null || povPageList.GetLength() == 0) return false;
Boolean lbvFirstPage = false;
for (int livCntr = 1; livCntr <= povPageList.GetLength(); livCntr++)
{
PageLabel lorLabel = povPageList.GetItemAt(livCntr);
if (lorLabel != null && lorLabel.lbvPublish)
{
// Do only the first time
if (!lbvFirstPage)
{
lbvFirstPage = true;
lorDocument = new Document(lorReader.GetPageSizeWithRotation(lorLabel.livPageNumber));
// Initialize an instance of the PdfCopyClass with the source document and an output file stream:
lorPdfCopyProvider = new PdfCopy(lorDocument, new System.IO.FileStream(povOutputDocument, System.IO.FileMode.Create));
lorDocument.Open();
}
// Extract the desired page number:
lorImportedPage = lorPdfCopyProvider.GetImportedPage(lorReader, lorLabel.livPageNumber);
lorLbls.AddPageLabel(livCntr, 1, lorLabel.lorPageLabel);
lorPdfCopyProvider.AddPage(lorImportedPage);
}
}
lorPdfCopyProvider.Close();
lorDocument.Close();
lorReader.Close();
return true;
}
catch (Exception ex)
{
lorDocument.Close();
lorReader.Close();
return false;
}
}
This is the page label.

How to open PowerPoint Presentation in New Tab in ASP.NET MVC C# project

I am working on an ASP.NET MVC application which have a some power point which I want to display it on new tab.
I had used openxml to read files but I don't know how to open it.
My code for reading the files:
public ActionResult Index()
{
StringBuilder sb = new StringBuilder();
string file = Server.MapPath("~/PPTFiles/Test.pptx");
int numberOfSlides = CountSlides(file);
string slideText;
for (int i = 0; i < numberOfSlides; i++)
{
// Get slide text.
GetSlideIdAndText(out slideText, file, i);
sb.Append(slideText);
}
return View();
}
public static int CountSlides(string presentationFile)
{
using (PresentationDocument presentationDocument = PresentationDocument.Open(presentationFile, false))
{
return CountSlides(presentationDocument);
}
}
public static int CountSlides(PresentationDocument presentationDocument)
{
if (presentationDocument == null)
{
throw new ArgumentNullException("presentationDocument");
}
int slidesCount = 0;
PresentationPart presentationPart = presentationDocument.PresentationPart;
if (presentationPart != null)
{
slidesCount = presentationPart.SlideParts.Count();
}
return slidesCount;
}
public static void GetSlideIdAndText(out string slideText, string docName, int index)
{
using (PresentationDocument ppt = PresentationDocument.Open(docName, false))
{
PresentationPart part = ppt.PresentationPart;
OpenXmlElementList slideIds = part.Presentation.SlideIdList.ChildElements;
string relId = (slideIds[index] as SlideId).RelationshipId;
SlidePart slide = (SlidePart)part.GetPartById(relId);
StringBuilder paragraphText = new StringBuilder();
IEnumerable<A.Text> texts = slide.Slide.Descendants<A.Text>();
foreach (A.Text text in texts)
{
paragraphText.Append(text.Text);
}
slideText = paragraphText.ToString();
}
}
Can you please help me with this?
You can't open pptx file in a browser. You should put your .pptx file in a directory on server. And link it to a button. When User Clicks on button. It Will open.

File used by another process ; PDF.JS ; iText

I'm using PDF.JS to display document that I upload to the server in canvas element using PDF.JS that's working perfectely. That time i'm using iTextSharp to digitally sign the document. When i try to sign the document an Exception is throwed (Exception.IO.Exception) The file is already used by another process. here is my Code for uploding the file :)
[HttpPost]
public async Task<JsonResult> Upload()
{
string fileName = null;
try
{
foreach (string item in Request.Files)
{
var fileContent = Request.Files[item];
if(fileContent != null && fileContent.ContentLength > 0)
{
var inputStream = fileContent.InputStream;
fileName = fileContent.FileName;
string path = Path.Combine(Server.MapPath("~/UploadFolder"), fileName);
using (fileContent.InputStream)
{
using (var stream = new FileStream(path, FileMode.Create))
{
await inputStream.CopyToAsync(stream);
}
}
}
}
}
catch (Exception e)
{
return Json("Upload failed");
}
return Json(fileName);
}
There's how i display PDF in canvas
$(document).ready(function () {
$("#btn2").click(function () {
var url = document.getElementById("document-to-sign").getAttribute("required-document");
if (url != "" && url != null) {
var pdfDoc = null,
pageNum = 1,
pageRendering = false,
pageNumPending = null,
scale = 1.5,
canvas = document.getElementById('document-to-sign'),
ctx = canvas.getContext('2d');
function renderPage(num) {
pageRendering = true;
pdfDoc.getPage(num).then(function (page) {
var viewport = page.getViewport(scale);
canvas.height = viewport.height;
canvas.width = viewport.width;
var renderContext = {
canvasContext: ctx,
viewport: viewport
};
var renderTask = page.render(renderContext);
renderTask.promise.then(function () {
pageRendering = false;
if (pageNumPending !== null) {
renderPage(pageNumPending);
pageNumPending = null;
}
});
});
document.getElementById('page_num').textContent = pageNum;
}
function queueRenderPage(num) {
if (pageRendering) {
pageNumPending = num;
} else {
renderPage(num);
}
}
function onPrevPage() {
if (pageNum <= 1) {
return;
}
pageNum--;
queueRenderPage(pageNum);
}
document.getElementById('prev').addEventListener('click', onPrevPage);
function onNextPage() {
if (pageNum >= pdfDoc.numPages) {
return;
}
pageNum++;
queueRenderPage(pageNum);
}
document.getElementById('next').addEventListener('click', onNextPage);
PDFJS.getDocument(url).then(function (pdfDoc_) {
pdfDoc = pdfDoc_;
document.getElementById('page_count').textContent = pdfDoc.numPages;
renderPage(pageNum);
});
PDFJS.disableStream = true;
$("#document-to-sign").removeAttr("required-document");
}
});
I finally that's how i'm signing the document (Adding the empty field to sign)
public static void AddField(string src,
Double x1X, Double x1Y, Double x2X, Double x2Y, int page,
string User)
{
try
{
PdfReader reader = new PdfReader(src);
using (PdfStamper s = new PdfStamper(reader, new FileStream(src, FileMode.Open)))
{
PdfFormField field = PdfFormField.CreateSignature(s.Writer);
field.FieldName = "Signature de " + User;
field.SetWidget(new Rectangle(Convert.ToSingle(x1X), Convert.ToSingle(x1Y), Convert.ToSingle(x2X), Convert.ToSingle(x2Y)), PdfAnnotation.HIGHLIGHT_PUSH);
field.Flags = PdfAnnotation.FLAGS_PRINT;
s.AddAnnotation(field, page);
}
}
catch (Exception e)
{
logger.Fatal(e.ToString());
throw e;
}
}
I'm stacked in this line
using (PdfStamper s = new PdfStamper(reader, new FileStream(src, FileMode.Open)))
EDIT:
I'm just adding the siging field in this step. Signing the document will be the next task, in console application i'm singing the document with a self-certificate.
Upload the document, and adding the signing field and signing it will be further :)
Sorry for the confussion.
Thanks a lot. :)
I just found what i'm missing in reading the file
refer to this
Cannot access the file because it is being used by another process
i was passing the url of the file instead of reading the all bytes from stream
PdfReader reader = new PdfReader(src);
PdfReader reader = new PdfReader(System.IO.File.ReadAllBytes(filePath))

AutoCAD .net Side loading a dwg with ReadDwgFile then Plotting

I used the example here to side load dwgs into memory combined with the example here of Plot From Model Space. I got things working except for the plots are not respecting whether the layers are frozen or not and printing as if they were all thawed. The data coming in from the dwg is correct. I can iterate the layers while debugging and verify the correct ones are either frozen or thawed. Also If I just saveas the dwg to a new name it matches the original concerning the layer state.Any Ideas?

Not ideal but I found a work around. If I iterate the LayerTable, check for frozen then make IsPlottable false it prints correctly. If a better soultion is available please let me know. Thanks
LayerTable _LayerTable = acTrans.GetObject(db.LayerTableId, OpenMode.ForRead) as LayerTable;
foreach (ObjectId _LayerTableId in _LayerTable)

Save email message as eml using C# in Lotus Notes

I need to export (save to) hard drive my Lotus Notes emails.
I figured out the way how to save attachments to HDD, but I can't figure out the way of how to save the whole email.
The code below shows how I export attachments. Can you suggest how can I modify it to save emails?
PS- I am new to programming.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Domino;
using System.Collections;
namespace ExportLotusAttachments
{
class Class1
{
public void ScanForEmails()
{
String textBox1 = "c:\\1";
NotesSession session = new NotesSession();
session.Initialize("");
NotesDbDirectory dir = null;
dir = session.GetDbDirectory("");
NotesDatabase db = null;
db = dir.OpenMailDatabase();
NotesDatabase NDb = dir.OpenMailDatabase(); //Database connection
//ArrayList that will hold names of the folders
ArrayList LotusViews2 = new ArrayList();
foreach (NotesView V in NDb.Views)
{
if (V.IsFolder && !(V.Name.Equals("($All)")))
{
NotesView getS = V;
LotusViews2.Add(getS.Name);
}
}
foreach (String obj in LotusViews2)
{
NotesDocument NDoc;
NotesView nInboxDocs = NDb.GetView(obj);
NDoc = nInboxDocs.GetFirstDocument();
String pAttachment;
while (NDoc != null)
{
if (NDoc.HasEmbedded && NDoc.HasItem("$File"))
{
object[] AllDocItems = (object[])NDoc.Items;
foreach (object CurItem in AllDocItems)
{
NotesItem nItem = (NotesItem)CurItem;
if (IT_TYPE.ATTACHMENT == nItem.type)
{
String path = textBox1;
pAttachment = ((object[])nItem.Values)[0].ToString();
if (!System.IO.Directory.Exists(path))
{
System.IO.Directory.CreateDirectory(textBox1);
}
try
{
NDoc.GetAttachment(pAttachment).ExtractFile(#path + pAttachment);
}
catch { }
}
}
}
NDoc = nInboxDocs.GetNextDocument(NDoc);
}
}
}
}
}
This post by Bob Babalan explains how to export lotus documents using Java. The same principle should work in C# or VB. The document is cnverted into MIME and written to the disk.
Or in version 8.5.3 (I think it started witn 8.5.1) you can just drag and drop it from the mail file to the file system.
I know it is a bit late, but this is, what I did. (Based on Bob Babalan)
Bobs Solution helped me alot to understand NotesMIMEEntities, but in his solution, he only traversed the MIME-Tree to the second "layer". This will traverse multiple layers.
public static void GetMIME(StreamWriter writer, NotesMIMEEntity mimeEntity)
{
try
{
string contentType = null;
string headers = null;
string content = null;
string preamble = null;
MIME_ENCODING encoding;
contentType = mimeEntity.ContentType;
headers = mimeEntity.Headers;
encoding = mimeEntity.Encoding;
// message envelope. If no MIME-Version header, add one
if (!headers.Contains("MIME-Version:"))
writer.WriteLine("MIME-Version: 1.0");
writer.WriteLine(headers);
// for multipart, usually no main-msg content...
content = mimeEntity.ContentAsText;
if (content != null && content.Trim().Length > 0)
writer.WriteLine(content);
writer.Flush();
if (contentType.StartsWith("multipart"))
{
preamble = mimeEntity.Preamble;
NotesMIMEEntity mimeChild = mimeEntity.GetFirstChildEntity();
while (mimeChild != null)
{
GetMimeChild(writer, mimeChild);
mimeChild = mimeChild.GetNextSibling();
}
}
writer.WriteLine(mimeEntity.BoundaryEnd);
writer.Flush();
}
catch (Exception ex)
{
Logging.Log(ex.ToString());
}
}
private void GetMimeChild(StreamWriter writer, NotesMIMEEntity mimeEntity)
{
string contentType = null;
string headers = null;
string content = null;
string preamble = null;
MIME_ENCODING encoding;
contentType = mimeEntity.ContentType;
headers = mimeEntity.Headers;
encoding = mimeEntity.Encoding;
if (encoding == MIME_ENCODING.ENC_IDENTITY_BINARY)
{
mimeEntity.EncodeContent(MIME_ENCODING.ENC_BASE64);
headers = mimeEntity.Headers;
}
preamble = mimeEntity.Preamble;
writer.Write(mimeEntity.BoundaryStart);
if (!content.EndsWith("\n"))
writer.WriteLine("");
writer.WriteLine(headers);
writer.WriteLine();
writer.Write(mimeEntity.ContentAsText);
if (contentType.StartsWith("multipart"))
{
preamble = mimeEntity.Preamble;
NotesMIMEEntity mimeChild = mimeEntity.GetFirstChildEntity();
while (mimeChild != null)
{
GetMimeChild(writer, mimeChild);
mimeChild = mimeChild.GetNextSibling();
}
}
writer.Write(mimeEntity.BoundaryEnd);
writer.Flush();
}
I would call this methods like this, to save the EML-File to a given path.
using (FileStream fs = new FileStream (path,FileMode.Create,FileAccess.ReadWrite,FileShare.None))
{
using (StreamWriter writer = new StreamWriter(fs))
{
NotesMimeEntity mimeEntity = notesDocument.GetMIMEEntity();
if (mimeEntity != null)
GetMIME(writer, mimeEntity);
}
}

Encoder SDK 4 - Push to Publishing Point

I'm coding an application in c# using EC4 SP2 SDK.
I want to publish my file to a media server publishing point. I've searched and found 2 examples regarding seting up and auth on publishing points, but either are from older sdk's or do not work (and are for console). basicly my application doesn't encode nothing, as if it had nothing to encode.
When in degub mode checkpont i can see the correct properties for the source file and for the server.
The encoding process takes 0secs to process. I checked the logs on the server events and i get a warning "the security system has received and auth request that could not be decoded". I just havo no knowledge to break up further than this. Any help would be appreciated.
this is the piece of code:
private void broadcastSourceFileToMediaServer2()
{
using (LiveJob job = new LiveJob())
{
String filetoencode = #"c:\temp\niceday.wmv";
LiveFileSource filesource = job.AddFileSource(filetoencode);
filesource.PlaybackMode = FileSourcePlaybackMode.Loop;
job.ActivateSource(filesource);
job.ApplyPreset(LivePresets.VC1Broadband4x3);
//don't know which one is good to use
job.AcquireCredentials += new EventHandler<AcquireCredentialsEventArgs>(job_AcquireCredentials);
_myUserName = "indes";
_pw = PullPW("indes");
Uri url = new Uri("http://192.168.1.74:8080/live");
PushBroadcastPublishFormat pubpoint = new PushBroadcastPublishFormat();
pubpoint.PublishingPoint = url;
pubpoint.UserName = _myUserName;
pubpoint.Password = _pw;
job.PublishFormats.Add(pubpoint);
job.PreConnectPublishingPoint();
job.StartEncoding();
statusBox.Text = job.NumberOfEncodedSamples.ToString();
job.StopEncoding();
job.Dispose();
}
}
public static string _myUserName { get; set; }
public static SecureString _pw { get; set; }
//codificação de Password a enviar
private static SecureString PullPW(string pw)
{
SecureString s = new SecureString();
foreach (char c in pw) s.AppendChar(c);
return s;
}
static void job_AcquireCredentials(object sender, AcquireCredentialsEventArgs e)
{
e.UserName = _myUserName;
e.Password = _pw;
e.Modes = AcquireCredentialModes.None;
}
Progresses:
I managed to authenticate (at least get a positive audit event) on the server.
I changed from this:
//don't know which one is good to use
job.AcquireCredentials += new EventHandler<AcquireCredentialsEventArgs>(job_AcquireCredentials);
_myUserName = "indes";
_pw = PullPW("indes");
Uri url = new Uri("http://192.168.1.74:8080/live");
PushBroadcastPublishFormat pubpoint = new PushBroadcastPublishFormat();
pubpoint.PublishingPoint = url;
pubpoint.UserName = _myUserName;
pubpoint.Password = _pw;
To this:
job.AcquireCredentials += new EventHandler<AcquireCredentialsEventArgs>(job_AcquireCredentials);
_myUserName = #"mediaservername\user";
_pw = PullPW("user_password");
Uri url = new Uri("http://192.168.1.74:8080/live");
PushBroadcastPublishFormat pubpoint = new PushBroadcastPublishFormat();
pubpoint.PublishingPoint = url;
If you see on one side if had to include the domain (either domain or computername) before username. this changed the failed audit events on the server, so i could eliminate the manual credentials pubpoint.username and pubpoint.Password.
Now I'm just dealing with a lack of output format exception. On to it.

Sadly I dont have enough rep to comment, so I have to write it as an answer.
Due to you are starting a live job, in order to stream you should not call job.StopEncoding() right after StartEncoding. I think usually you would use an event to stop the encoding. If you start encoding and immediately stop it, it is only logical you have no, or only a very small output.
I changed your code to the following and it seems work well. I guess your problem is that you disposed the instance of LiveJob class. You have to keep the instance alive before it finished encoding the whole stream. So change the using part and remove the StopEncoding and Dispose will be OK.
private void broadcastSourceFileToMediaServer2()
