Product fixes in this release:
  • Corrected MGet sample project so that it no longer contains the source code for the MPut project. Affected CSharp sample only.

  • Added overload to delete method that allows deletion of single file rather than a wildcard that could resolve to multiple files.

Product fixes in this release:

2.3.0.0    Released: 2005-05-10

  • We strive to continually upgrade our products with new features. Besides improving interoperability with more server implementations, this release adds the following new properties:

    • UseControlAddressForPassive property. Besides setting a record for our use of Hungarian notation, this property allows you to override the address returned from the server when the PASV command is sent. The default is false. If set to true, the IP address of the control connection will be used for establishing the data connection. This is used to establish a data connection to a firewall when the firewall was not smart enough to correctly modify the server's response to the PASV command.
    • UseIpSync property. The XP SP2 firewall enhancement does not respond correctly to the IP/SYNC signal used for aborting a file transfer (neither do many servers). Through the use of this property, your users can control the use of this feature when aborting a file transfer.
    • MaxTransferRate property. Since FTP file transfers can be processor intensive, customers have asked us to throttle the transfer speed. If the value of this property is below the actual transfer rate, the worker thread will be put to sleep each second to slow the actual rate to match this value.
Product fixes in this release:
  • Deep recursive directories greater than 512 characters now supported  (1231)
  • MaxTransferRate property added to throttle transfers  (1731)
  • UseControlAddressForPassive property added to allow bypassing of "dumb" or encyrypting firewalls  (1928)
  • Fixed problem with asynchronous stream STOR  (1955)
  • Fixed recovery from situation where all ports in local port range are in use  (1974)
  • Fixed problem using Invoke() after RawConnect()  (2112)
  • Fixed interoperability issue with server returning 220 for PASS  (2113)
  • Fixed interoperability issue with Titan server that does not close control connection  (2117)
  • Improved listing parsing for UNIX servers  (2145)
  • Fixed interoperability issue with server that returns LF instead of CRLF  (2466)
  • UseIpSync property added to control the use of IP/SYNC when aborting a file retrieve  (2613)
  • AbortTransfer() now send ABOR when storing files, for compatibility with some server  (2670)
  • Improved exception handling doing a GET when local disk if full  (2677)
  • Modified FtpWebRequest.Close() to close control connection  (2764)
  • ConnectedChanged event is now properly raised when control connection is closed  (2827)
  • 0-length files can now be retrieved  (3081)
  • GlobalScape persists marker, so reset to 0 for transfers  (3090)
2.2.5.0    Released: 2003-10-31
  • This release is a major maintenance update. The version number of the installation kit has been incremented to match the assembly to minimize confusion. For more information, please see the Readme file included with the installation. All the samples have been revised and ASP.NET samples are now included with installation, rather than just from the Web. Plus, all ASP.NET samples now automatically create virutal directories upon installation, making ASP.NET testing easier
