Xceed FTP Library

The fully self-contained ActiveX DLL at the core of the library is all that developers need to include with their applications. The library also supports all the available ActiveX functionality designed to make a programmers job easier, such as categorized properties, built-in constants and enumerations, context-sensitive F1-help and built-in help strings.

Written entirely with threadsafe code in Visual C++ 6.0 with ATL 3.0, and supporting both the single-threaded and multi-threaded apartment models, the Xceed FTP Library has very low memory requirements and is perfectly suited for use in environments running multiple FTP operations simultaneously. It also runs without any screen output, can create log files and works in the background if necessary.

The library comes with support for almost all of todays 32-bit development languages, including Visual Basic, Visual C++, Delphi, C++Builder, Visual FoxPro and Office suite products.

All Xceed Software products include comprehensive online documentation, free expert technical support, royalty-free distribution and a 60-day money-back guarantee.

Features

ActiveX technology

• A single fully self-contained COM object and ActiveX component written with ATL 3.0
• Requires no external compression DLLs, MFC DLLs or runtime libraries
• Both single-threaded (STA) and multi-threaded apartment (MTA) model design
• Instantiate the component dynamically without putting it on a form
• Supports multiple instances running simultaneously
• Optional background processing so your code can continue execution while the Xceed FTP Library is working
• Supports both Unicode and Ansi in one single component. The library automatically uses Unicode API calls for best performance when running on Windows NT.
• Supports notification by Events or by Custom Interface Advising for maximum efficiency
• ActiveX component interface has all constants, enumerations and types built-in. Code completion, property categories, help strings and context-sensitive F1-help fully supported
• Works with all 32-bit development environments that can use ActiveX components, including VB, VC++, Delphi, C++ Builder, VFP, Office, PB, VO, Web scripting languages, ASP and DCOM projects

FTP support and major operations

• RFC 959, 1123 and 1579 compliant
• Fully uses Winsock-2 optimizations for best performance
• SOCKS Firewall Proxy support for performing FTP operations across intranet firewalls
• Passive mode
• Supports all standard FTP commands as well as custom FTP commands
• Send and receive files to/from disk or directly to/from memory buffers
• Send and receive entire directory structures recursively
• QuickFTP interface for transferring one or more files with only a single line of code
• Server directory listings are available through events or via easy to manipulate item collections
• Automatic directory listing parser or create your own custom parser for unknown listing formats
• Resume file transfers from any offset
• Streaming support. Send or receive data as it becomes available
• Rename or change file paths as they are being sent or received

Application-component interactivity

• Operations can be aborted at any time
• Provides status report events on a file-by-file basis as well as on the entire operation being performed, with various percentages, byte and file counts. Easily add any kind of progress bar to your application.
• Events are triggered whenever a file is being sent, received, listed, etc.
• Notifies your application when and why a specific file cannot be processed.
• Notifies your application when a file being received is about to overwrite an existing file. Your application can then choose to overwrite it or skip it.
• Provides complete file information for the current file being processed.
• Your application receives info such as the amount of time a file took to transfer, the achieved transfer rate, and other info, as it becomes available.
• Create your own custom filters in order to process or exclude files based on size or date
• Automatic full yield so other applications do not halt during processing.

Other operations

• Allows sending files that are currently open for write operations by other processes
• Supports long filenames, UNC paths and Unicode filenames
• Specify files to process using wildcards

Documentation and samples

• The complete documentation is available as a fully context-sensitive Windows .hlp file that is automatically opened to the right topic by pressing F1 on a keyword in your programming language
• Documentation also included in the form of a printable Word document
• Fully commented sample applications for various languages, including VB, Delphi, Visual C++ and Active Server Pages
