I am trying to zip files to a memory stream but the stream content is always 0 even if the stream length seem correct.

MemoryStream ms = new MemoryStream();

Telerik.Windows.Zip.ZipPackage z = null;

z = Telerik.Windows.Zip.ZipPackage.Create(ms);
z.Add(fi.FullName);

Data = null;

System.IO.BinaryReader reader = new System.IO.BinaryReader(ms);
Data = new byte[(int)ms.Length];
reader.Read(Data, 0, (int)ms.Length);
ms.Close();

--> Data contains only "0".

Can you pls advise ?

Thanks

response.end

Hello
is it possible to send a file to the end user without a repsonse.end, that way it would be possible to show a loading panel while the zip is building

[Solved] Error unzipping in WCF

Hello


I'm trying to create a ZIP file from Silverlight with a list of JSON data and compresses well. 
The problem is to receive it in the server because I have no library Telerik receive the Zip to 
extract and process the result. The library I am using is IonicZip to receive the result but 
I get error trying to read the MemoryStream. Is there a library for ASP.net Telerik decompress 
the ZIP file

Code in Silverlight:
MemoryStream memoryStream = new MemoryStream();
ZipCompression method = ZipCompression.Default;
Telerik.Windows.Zip.ZipOutputStream zipOutputStream = new Telerik.Windows.Zip.ZipOutputStream(memoryStream, method);
StreamWriter writer = new StreamWriter(zipOutputStream);
writer.Write(listSave.ToJSON());
writer.Flush();
ServicesClient context = new ServicesClient();
context.SetZipFileAsync( Convert.ToBase64String(memoryStream.ToArray()));

Code in WCF:
public void SetZipFile(string _parameter)
     {
         if (!string.IsNullOrWhiteSpace(_parameter))
         {
             var info = Convert.FromBase64String(_parameter);
             MemoryStream stream = new MemoryStream(info);
             string dataList = string.Empty;
             MemoryStream output = new MemoryStream();
             StreamReader read = new StreamReader(output);
             using (ZipFile zip = ZipFile.Read(stream))
             {
                 ZipEntry item = zip[0];
                 item.Extract(output);
                 output.Seek(0, SeekOrigin.Begin);
                 dataList = read.ReadToEnd();
             }
         }
     }

[Solved] Zip control does not decompress correctly

Hello,

I am trying the ZIP control for silverlight, but i keep having an issue.
I am trying to Compress and Uncompress a stream which is getting read from a WAV file.
the issue is that the size of the stream before compression and after decompression is different. this causes the uncomressed stream to be invalid and therefore not to be played by the basic media element of silverlight.

I am attaching a sample of code to demonstrate the zip and unzip methods that i use.

string wavFilePath = @"C:\1\cheer.wav";

string wavFileNewPath = @"C:\1\cheerNew.wav";

string zipFilePath = @"c:\1\123.zip";

private void btnCompress(object sender, RoutedEventArgs e)

{

FileStream fs = new FileStream(wavFilePath, FileMode.Open);

SizeBefore.Text = fs.Length.ToString();

using (ZipPackage zipFile = ZipPackage.CreateFile(zipFilePath))

{

zipFile.AddStream(fs, "cheer.wav", ZipCompression.Default, DateTime.Now);

zipFile.Close(true);

}

private void btnUncompress(object sender, RoutedEventArgs e)

{

using (ZipPackage zipFile = ZipPackage.OpenFile(zipFilePath, FileAccess.Read))

{

ZipPackageEntry zipEntry = zipFile.ZipPackageEntries[0];

Stream strm = zipEntry.OpenInputStream();

byte[] Bytes = new byte[strm.Length];

strm.Read(Bytes, 0, (int)strm.Length);

using (FileStream fs = new FileStream(wavFileNewPath, FileMode.Create))

{

fs.Write(Bytes, 0, Bytes.Length);

fs.Close();

}

I wanted to also note that I did encounter the decompress example which is online here. but it does not help me since dealing with string will not give me the expected result.

Thank you in advance for nay help about this...

Uncompress on Server Fails

I am compressing a string on the client (and can uncompress it on the client). Thus, I know it is working.

However, what is the appropriate technical for uncompressing the string once its been sent over to the server?

I am using WCF web services.

I've added a reference to Telerik.Windows.Zip but the DLL throws an error when I attempt to create the object:

Dim inputStream As New ZipInputStream(memStream)

Can the DLL not be used on the server side? If not, how do I uncompress the data?

-Dave
