[Solved] File corrupted after zipping

I'm trying to zip a PDF file, it creates zip file correctly, but if I try to open compressed PDF file, it show me error message "Corrupted file" (I'm trying to open by my PDF reader), where I wrong?

using (Stream stream = File.Open(fileFullName, FileMode.Create))
                    {
                        using (ZipArchive archive = new ZipArchive(stream, ZipArchiveMode.Create, false, null))
                        {
                            using (ZipArchiveEntry entry = archive.CreateEntry(fi.Name))
                            {
                                var writer = new StreamWriter(entry.Open());
 
                                using (Stream streamFileToZip = File.Open(fi.FullName, FileMode.Open))
                                {
                                    var buffer = new byte[4096];
                                    int sourceBytes = 0;
                                    do
                                    {
 
                                        sourceBytes = streamFileToZip.Read(buffer, 0, buffer.Length);
                                        writer.Write(buffer);
 
                                    } while (sourceBytes > 0);
 
                                }
 
                                writer.Flush();
                            }
                        }
                    }

File size limits?

I'm currently using Telerik.Windows.Zip 2016.2.606.40.

Are there any file size limits, either to individual files in a ZIP or to the ZIP as a whole?

I'm getting an exception "Relative offset of the Central Directory Start is too big" while trying to process a large (~3GB) stream.

 

Thanks.

[ERROR] LibreOffice/OpenOffice .docx files HtmlFormatProvider Export

Hi;

I'm having problems, when I try to export with HtmlFormatProvider the OpenOffice/LibreOffice docx files.

If the file is created with MSWord there's no problems, all works fine, the problem is with LibreOffice/Openoffice generated-documents.

Please, I need help 'cause some of my customers uses LibreOffice to create the docx documents.

+++++++++++++++++++++++ CODE ++++++++++++++++++++++++++

                docxProvider = new DocxFormatProvider();
                htmlProvider = new HtmlFormatProvider();

                if(this._DocXByteArray == null)
                    this._DocXByteArray = System.IO.File.ReadAllBytes(this._DocXPath);

                document = docxProvider.Import(this._DocXByteArray);
                        
                htmlProvider.ExportSettings.DocumentExportLevel = DocumentExportLevel.Fragment;
                htmlProvider.ExportSettings.ImagesExportMode = ImagesExportMode.Embedded;
                htmlProvider.ExportSettings.StylesExportMode = StylesExportMode.Embedded;
                        
                string html = htmlProvider.Export(document); //heres crash with the down error trace

+++++++++++++++++++++++ CODE ++++++++++++++++++++++++++

I'm always getting this error

Export from RadFixedDocument to Stream
Hello,

I'm attempting to split a Pdf by removing pages.  After page removal, I export the RadFixedDocument back to a PDF through a stream.  I've tried various streams like MemoryStream and FileStream without luck.  All PDFs come about with blank pages.  Code is below.

public static IEnumerable<string> SplitPdf(PdfFileDefinition pdfFileDef)
       {
           List<string> pdfs = new List<string>();
           Stream stream = null;
           PdfFormatProvider formatProvider = new PdfFormatProvider();
 
           // Save temp file to disk
               var path = @"c:\temp";
               if(!Directory.Exists(path))
                   Directory.CreateDirectory(path);
            
           // Pdf streams must support read & seek operations    
           var fileUri = new Uri(pdfFileDef.FilePath);
            
           // Is pdf a file or resource
           if (fileUri.Scheme == "file")
           {
                 var tempFilePath = Path.Combine(path, "temp.pdf");
                 File.Copy(Path.Combine(path,fileUri.LocalPath), tempFilePath,true);
                 stream = File.Open(tempFilePath, FileMode.Open,FileAccess.Read);              
           }
           else if (fileUri.Scheme == "pack" && fileUri.Host.Contains("siteoforigin"))
           {                              
                stream = Application.GetRemoteStream(fileUri).Stream;   
           }
                        
           foreach(var pageBreak in pdfFileDef.PageBreaks)
           {                                                       
               RadFixedDocument document = new PdfFormatProvider(stream, FormatProviderSettings.ReadOnDemand).Import();
               RadFixedDocument splitDocument = new RadFixedDocument();  
               splitDocument = document;
                           
               for (int pageNumber = splitDocument.Pages.Count - 1; pageNumber >= 0; pageNumber--)
               {
                   if(!pageNumber.IsBetween<int>(pageBreak.StartPage, pageBreak.EndPage))
                   {
                       splitDocument.Pages.RemoveAt(pageNumber);
                   }
 
               }
                              
              // Generate temp pdf file for review
               var fileName = Path.Combine(path, Path.GetRandomFileName());
               fileName = Path.ChangeExtension(fileName, ".pdf");             
                               
               // Export filestream to Pdf
               using(var fs = new FileStream(fileName,FileMode.Create))
               {                               
                    formatProvider.Export(splitDocument, fs);    
                     
               }                                           
 
               pdfs.Add(fileName);
                                                              
           }
 
           return pdfs;
       }
