Read A PDF And And Save The Changes Using Itextsharp.dll?

Jul 1, 2010

I have web page named DocComments.aspx in which i created one table . one td contains document options for a pdf file which will be displayed in another td.I used iframe to display the td.

document.getElementByID('tdDocview').innerHTML="<iframe src='DocView.aspx?DocID="+Id+"' frameborder='0' name='docview' width='100%' scrolling='no' id='docview' title='docview' height=" + iHeight + " ></iframe>";

Document options are Move/copy-move a pdf file or create a pdf based on page number and range. Rotate page - rotate 90,180,270 Along with this option i need to add typewriter function in the pdf file which is going to load. I have used itextsharp dll for all the document options.Also i enabled the typewriter option in pdf file.If a user uses the typewriter and add comments,then i need to save that changes.I have stored all the pdf's in db. My problem is how to read that pdf file and save the changes using itextsharp.dll

Web Forms :: Open Save Dialoge From Button Click To Save Including CSS?

Feb 4, 2011

My page (which basically contains a pair of Repeaters) renders and is displayed to the user.I'd like to have a "Download" button on the page which, when clicked, will propmt the user to save the page locally as an html file without losing any of the CSS formatting.

My CSS files are linked to via a Master Page.Currently, I have the button linked to some javascript that open will the Save As dialog, but all of the CSS formatting is lost, and it saves the page .I'm assuming that the button will need to open a new page which will re-create the data for the Repeaters and then save using StreamWriter, but I'm not exactly sure if that's right or how best to do it.

Feb 17, 2011

I have one AsyncFileUpload control ,one Attach button,one Listbox and Save button.

In Attach button click event i added the filename to listbox and saved the Asyncfileupload controls in different session variable.

When user clicks on save button all files has to be saved in application folder and for this i wrote the following code.


But iam unable to save all the files . Suppose i added two AsyncFileupload controls to session variables, only last file i,e. 2nd file can only be saved and couldn't get first file.

Save String To Client With Open/Save Dialog?

Aug 8, 2010

I am using the following code to write the contents of a string (converted to a byte array) to the client in ASP.NET/C#

byte[] data = StrToByteArray(strData);
Response.AppendHeader("content-length", data.Length.ToString());
Response.ContentType = "text/plain";
Response.AppendHeader("content-Disposition", "attachment;filename=" + fileName);

fileName is the name of the file ending with the file extension (.pgn). However, the file is saved as a .txt file, ignoring the extension that I am giving it. Would this have to do with the Response.Contenttype = "text/plain"? How can I get the Open/Save dialog to display and save the correct (.pgn) filename?

Also, if filename is a string separated by dashes or spaces, when the Open/Save dialog comes up, the filename is not displayed in its entirety but it is truncated where the first dash (-) or space (or comma) is encountered. How can this be remedied?

How To Use PdfSmartCopy From ItextSharp

Nov 25, 2010

I am trying to use PdfSmartCopy from ItextSharp but I cannot find any relevant examples in c#. The ideea is that I have a pdf containing form fields and the fields add 700kb to the size of the pdf document. The original document without form fields was 100kb. Any other sugestions are welcome, especially o reduce the pdf size consistently. (I optimised the generated PDF with adobe acrobat, and it reduced it to 44kb. So there must be a glitch somewhere.) Is there any way to reduce the PDF size? Edit: FormFlatenning doesn't . The pdf template file contains only text, lines and tables, no images.

here's my code snippet

PdfReader reader = new PdfReader(GetTemplateBytes());
pst = new PdfStamper(reader, Response.OutputStream);
var acroFields = pst.AcroFields;
pst.FormFlattening = true;
pst.FreeTextFlattening = true;

C# - Generate PDF With ITextSharp

Apr 1, 2011

I am trying to add an image to the top of every page on an existing PDF. I have tried using PdfStamp but for some reason when I try to print the pdf from Chrome all I get is a black page. Also Adobe Reader only shows the original document. Does anyone have any ideas on how to get it working? Here is the code.

public partial class MakePdf : System.Web.UI.Page
public MemoryStream m = new MemoryStream();
protected void Page_Load(object sender, EventArgs e)
Document document = new Document(PageSize.LETTER);
Response.ContentType = "application/pdf";
string RESULT = @"C:UsersmaitchisonDocumentsPdfService Report Search - 650-10-067 4114.pdf";
PdfReader reader = new PdfReader(RESULT);
PdfStamper stamp = new PdfStamper(reader, m);
// Set ContentType and create an instance of the Writer.
Response.ContentType = "application/pdf";
PdfWriter writer = PdfWriter.GetInstance(document, m);
writer.CloseStream = false;
// Open Document
int n = reader.NumberOfPages;
int i = 1;
PdfContentByte cb = writer.DirectContent;
PdfContentByte over;
