    Product Release History for PowerTCP Zip Compression for .NET

    The following is a list of public releases for all components shipped with PowerTCP Zip Compression for .NET (Latest Release 2010-08-05) 

     

    PowerTCP Zip Compression for .NET

       Current Version: 2.1.0.2

     

     

    2.1.0.2   Released: 2010-08-05


     

    • The self-extraction feature has been enhanced in a number of ways. First, it is now possible to direct the self-extraction to occur as soon as the file is opened (without need of user input). Second, a "silent" mode can be used, in which the extraction occurs automatically and no UI is presented to the user. Finally, it is now possible to specify a file to open immediately after extraction.
    • Zip Compression for .NET now supports .NET Framework 4 Client Profile.
    • Zip Compression for .NET has been updated with VS 2010 integration.

     

    Product fixes in this release:

    • Fixed the default value of the ExcludePattern property, which caused an error in some cases. (4884)
    • Archive now checks for a data descriptor when bit 3 is set to general flags. (4930)
    • Fixed an extraction issue when an AES 256 file was of a certain length. (4933)
    • Added better support for Unicode characters. (4958)
    • When a filename exceeds the system limit, an error is now correctly raised to the user. (4993)
    • Extracting a non-first file before the first file is extracted in a spanned archive no longer results in an error. (5000)
    • Uppercase 'Z' is now permitted in spanned file extensions. (5001)
    • Increased performance by decreasing time in which garbage collection is forced. (5025)
    • Fixed an issue with extracting spanned archives that have very small parts. (5068)
    • Fixed an issue with unzipping some very large files. (5168)
    • Providing an invalid standard encryption password now gives a more descriptive invalid password error. (5170)
    • Trying to extract a file with an incorrect password no longer creates a 0 byte file. (5272)
    • Writing directly to a Stream using Archive.Write has been fixed. (5331)

     

     

    2.0.2.3   Released: 2008-11-14


     

    • The new Archive.Delimiter property can be set when adding multiple sources to an archive with a single Add call. Perhaps more importantly, this also permits the adding of files and paths with commas, by changing from the default value of ",".

     

    Product fixes in this release:

    • A "Spanning cannot be used with self-extracting files" exception no longer occurs when a VS.NET 2005 or 2008 project is run after the Archive component is dragged onto a form. (4626)
    • Setting the archive Comment now works when using QuickZip. (4662)
    • Unzipping an archive that consists solely of an AES-encrypted 0 byte file no longer results in an error. (4721)
    • Files within an archive with Unicode names are now extracted correctly. (4722)
    • Zipping an opened file to a filename with differently cased letters no longer results in an error. (4736)
    • If an archive item decompressed to a stream, the stream is no longer closed if the Archive component is cleared. (4741)
    • Fixed an infinite loop issue that could occur if decompression was attempted on some malformed zip archives. (4760)
    • Zipping a 0 byte file using AES encryption now creates an archive that can be unzipped by other unzipping utilities. (4763)
    • Overwrite now works when it is passed in as a parameter of the Zip method. (4769)

     

     

    2.0.1.0   Released: 2008-03-06


     

    Product fixes in this release:

    • In VS.NET 2005+, the Archive component no longer throws a "Spanning cannot be used with self-extracting files" error after placing it on a form and building with default values. (4626)

    PowerTCP Zip Compression for .NET features

     

    PowerTCP Zip Compression for .NET Archive Component

    Use Dart's Archive component within the .NET Framework to compress, decompress, and encrypt files and streams.

    The Archive component provides both high-level ease of use for those developers who just want to write code as quickly as possible, and low-level power for those developers who require finer control. Features include:

    • Quickly compress a single file (or multiple files using wildcards...including recursive directory trees) with a single line of code.
    • Quickly decompress files with only a single line of code.
    • Compress to or from files or streams.
    • Customize the level of compression (high, medium, or low) based on your speed and size requirements.
    • Encrypt the output data using standard zip encryption.
    • Create a self-extracting zip file.
    • Supports spanning.
    • Manipulate the files in the archive on a global level (i.e. unzip all files at once, assign a comment to all files at once, etc) or on a file level (i.e. unzip a single file contained in the archive, assign the comment on a single file in the archive, etc).
    • C#, VB.NET, ASP.NET, and Delphi .NET sample projects included.
    • Integrates with Visual Studio 2005, 2008, 2010, 2012
    • .NET Framework 4 Client Profile compatible
