Hi,

I've been looking in to the getting started guide of the new PDFprocessing and was wondering how one could create a hyperlink in radPDFproecessing since I cannot find anything about it.

something like : editor.DrawText("Hello RadPdfProcessing!");      => but or a hyperlink like <a href=http://www.telerik.com>telerik is cool</a>

thanks,

I have a small console app that takes a collection of objects and generates a seperate excel file for each.  I am using EPPlus.  Does telerik have something like this or better?  And if so an example application?

Thanks

I'm trying to upgrade our controls, and I'm getting the error: The type or namespace name 'Zip' does not exist in the namespace 'Telerik.Web' (are you missing an assembly reference?

It looks like your examples still reference Telerik.Web.Zip.  Was there some change to the ZipLibrary in Q2?  I didn't see anything in the change log for it, and I upgraded our controls the same way that I usually do...

So could I used this in my WCF or C# Web API back end to create excel files or with the other new one, PDFs? 
Just use the Workbook workbook = new Workbook();  and then export to a stream and do whatever with it?

Hi,

I am searching for a way to export out a word document from my c# wpf application. I have a documentviewer that has a generated document. Does the words processing control allow this?

many thanks,

Hi,
I am working with some log files I generate with another application.  My intention is to archive them and then delete the large log file and have it stored in a compressed format for later access.    This works when I use ZipArchiveMode.Create.   Where this falls apart is that if I delete the file after I have added it to the archive, and then run the program again, it is not keeping the old entries in the archive - since I am using "Create".  I also wanted to save time that if the file I wanted to add was already in the archive, it would skip adding it.  A query against the Entries property of the ZipArchive does not seem to work when the mode is set to Create - it might work for the first time I ask, but once I add a file I get an error.  I then attempted to use ZipArchiveMode.Update, but then I received and ObjectDisposedException {"Cannot access a closed Stream."}.

I am using the code found in this post
http://www.telerik.com/forums/zip-content-of-a-folder-into-an-encrypted-zip-file
to add the existing files to the archive.

So I'm not sure if I am using the ZipArchive incorrectly, or I need to do it a different way, but help and guidance would be appreciated.  I can create a demo app if needed.

Thanks,
Chris

I'm trying to compress and decompress file with ZipLibrary. But it doesn't works. Can anybody help me?

 Private Function Compress(data As Byte()) As Byte()
        Dim result As Byte() = Nothing
        Try

Hello,

I used RadAsyncUpload control to accept a upload zip file. My zip file contains text delimiter files.  I am able to unzip it to a temporary directory, but if I try again with the same zip file I get error something like "...because it is being used by another process." (at line 17)

Below is my method to unzip:


Please help,

Thanks,

I have an application where I have been using the following code:

       using (ZipPackage zipPackage = ZipPackage.Open(stream, FileAccess.Read))
                    {
                        foreach (ZipPackageEntry file in zipPackage.ZipPackageEntries.ToList())
                        {
                            if (file.FileNameInZip.Equals("nsData.json"))
                            {
                                StreamReader streamReader = new StreamReader(file.OpenInputStream());
                                string jsonString = streamReader.ReadToEnd();
                            }
                       }
                 }

and it works as expected.

I have now tried to convert it to using ZipArchive instead, but I am having some problems.

I use the following code:

  using (ZipArchive archive = new ZipArchive(stream,ZipArchiveMode.Read, false, null))
                    {
                        System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();

                        ZipArchiveEntry entry = archive.GetEntry("nsData.json");
                        if (entry != null)
                        {
                            Stream entryStream = entry.Open();
                            StreamReader reader = new StreamReader(entryStream);
                            string content = reader.ReadToEnd();


                        }
            }

And when it comes to the last line it gives the following exception:

{Telerik.Windows.Zip.InvalidDataException: Invalid block length
   ved Telerik.Windows.Zip.DeflateDecompressor.DecodeBits()
   ved Telerik.Windows.Zip.DeflateDecompressor.DecodeUncompressedBlock(Boolean& endOfBlock)

I would be wery thankfull if you could explain to me what I am doing wrong.

Hi, i am ziping some .pdf files to after download, when I run at VS2010 the zip was create correct, but when deploy at server the zip was create with 1kb, the WinRar open and show an empty zip file. I don´t receive any error. If I create a small file(10MB) work well, the zip have about 70MB. But at production should be create zips with 1GB or more.

I tried in 2 servers, both with 8GB ram and Win 2008 64 bits.
