Hello XCeed experts,
I compress a string (called compressedDossier) like so (VB.NET):
Dim compressedDossier As String = System.Text.Encoding.Unicode.GetString( _ Xceed.Compression.Formats.XceedCompressedStreamEx.Compress( ...
we are currently testing the Xceed Ultimate Suite. In one of our projects, where we plan to use Xceed Zip, we have to estimate the expected compression rate of files and folders.
Is it possible to do such estimations with Xceed Zip without real compression of the files? If yes, which approach would you advise?
Best Regards,Jens Horn
I've used 2 different compression classes, one for .NET and one for Silverlight as follows:
I have one GZip archive, which I try to decompress using Xceed.Compression.Formats.GZipCompressedStream.
During decompessing I've got a error: ''The calculated checksum differs from the stored checksum.''.
But when I tryied to decomress this file with SharpZipLib.GZip.GZipInputStream or with 7-Zip - decomressing is ...
We have recently upgraded our app to .net 4.0. Our app was previously using XCeed 3.6.xxxx with .NET 2.0. We expereicned issues using the old version of XCeed in .net 4.0 so we decided to upgrade to XCeed zip V5.0.
Unzipping some files on my dev machine seemed to work fine, however when testing on a VM with Windows XP I would get the ...
When ever I speicify CompressionLevel.None in the ZipItemLocalHeader and then try to read the output stream I am getting this error.
Xceed.Compression.CompressionException: Expected end of stream not found

How to create an archive from the stream and path of the file. The archive should have the directory structure intact.Suppose a:\b\c\d\e.txt, when i unzip the archive, it should have the c\d\e.txt where is a:\b is the root directory.
the Deflate compression method is actually the default Zipping method, the one that has been around for more than 15 years.
I'm working on a program that read large csv files which can be several hundreds MBs. I noticed that compressing those files with zip would reduced the disk space used by 10.
I was thinking allowing my program to read zip files as well but only as a pass-through stream so that there is no overhead on the disk or memory usage.
I though the ...
I have been searching the site but can not find a definitive answer. Is it possible to create a multi-volume zip archive that is self-extracting? If so, at which version was this feature included?
