全面的接口：

 控件為 FTP和 HTTP 提供一個全面的接口，在應(yīng)用中為了合并文件傳輸，控件給開發(fā)者提供所有他所需要的任何東西并通過 FTP 進行遠程文件管理。除了通過文件名，URL，wild card模式下載和上載之外，開發(fā)者可以使用控件創(chuàng)建，分類，刪除目錄并且重新命名和刪除文件。一套道具和方法對開發(fā)者利用比如斷點續(xù)傳，在防火墻前的被動模式操作，支持自定義服務(wù)器命令等特性來說是十分充足的。

Internet標準：

 Catalyst 文件傳輸控件為 FTP 和 HTTP 執(zhí)行標準的 Internet 協(xié)議，確保與世界上各種類型服務(wù)器盡可能保持最高程度的兼容性。這些標準通過 Internet 工程工作小組被定義，并做為 RFC文檔發(fā)布。RFC 959 文檔也就是文件傳輸(FTP), 該文檔被用于在客戶端和服務(wù)器之間傳輸文件和在服務(wù)器上進行遠程管理。Internet 草案文檔 "用TLS保護 FTP " 描述了一種機制，該機制運行在FTP客戶端和服務(wù)器上，它使用在RFC 2246中定義的TLS協(xié)議和RFC 2228，RFC 1945，RFC 2616中定義的擴展FTP去執(zhí)行安全和鑒定。RFC 1945是超文本傳輸協(xié)議1.0版本，RFC 2616 是1.1版本。這些標準管理客戶端程序比如web服務(wù)器的瀏覽器的通信。文件傳輸控件執(zhí)行這些標準的 GET 和 PUT 命令。

特征和穩(wěn)定性：

 Catalyst 文件傳輸控件是建立在成功開發(fā)的 SocketTools 系列產(chǎn)品的牢固基礎(chǔ)之上的。那些自從1995年以來已經(jīng)被市場檢驗和證明了的相同核心技術(shù)和特性被用來創(chuàng)建文件傳輸。做為最主要的網(wǎng)絡(luò)組件軟件開發(fā)商，全世界成千上萬的開發(fā)者相信 Catalyst能設(shè)計出穩(wěn)定的組件，該組件能滿足建立可靠的世界級軟件的需要。

靈活性：

 文件傳輸控件被設(shè)計成帶有很大程度的靈活性，并且能夠通過各種編程語言在不同類型的開發(fā)環(huán)境下使用。它被作為標準的 ActiveX 控件所使用，并被象 Visual Basic, Visual FoxPro, Visual C++, Borland C++Builder, Delphi and PowerBuilder這樣的語言完全支持。此外,該控件也能夠被作為基本COM對象在象VBScript這樣的腳本語言中所使用。它在 ASP 和其他類似技術(shù)中也全面支持服務(wù)器端腳本。

被簡化的再分配：

 使用 ActiveX 模板庫建立的Catalyst 文件傳輸控件對第三方組件或Microsoft 支持庫沒有依賴性。這意味著只有控件本身需要被包含到使用它的程序中去，這就簡化了再分配和安裝軟件的過程從而減少了程序總的大小。

文件：

 和功能性一樣，特性和穩(wěn)定性很重要。全面的文件對應(yīng)用程序開發(fā)者來說同樣重要。這就是為什么Catalyst 文件傳輸產(chǎn)品包括了提供產(chǎn)品概要的開發(fā)者向?qū)В撓驅(qū)且粋€QuickStart 引導用以幫助開發(fā)者開始和緩和經(jīng)驗曲線，它提供一個完整的技術(shù)參考，該參考提供了控件所支持的每個屬性，方法和事件。文件的打印版和直接從開發(fā)環(huán)境中可以獲取的上下文相關(guān)的在線幫助都被包含在產(chǎn)品中。 為了幫助開發(fā)者熟悉控件特性，各種語言的實例程序也被包含在里面，并提供在用戶程序中可被重用的代碼。

• Comprehensive Interface
  The control offers a comprehensive interface for FTP and HTTP, providing the developer with everything that he needs to incorporate file transfers in an application, as well as remote file management using FTP. In addition to downloading and uploading by file name, URL, and wild card patterns, a developer may use the control for creation, listing, and removal of directories, as well as renaming and removal of files. The set of properties and methods is sufficiently rich to enable a developer to take advantage of features such as the resumption of interrupted transfers, passive mode operation in the presence of firewalls and support for custom server commands.
• Internet Standards
  The Catalyst File Transfer control implements the standard Internet protocols for FTP and HTTP, ensuring the highest degree of compatibility possible with servers of those types around the world. These standards are defined by the Internet Engineering Task Force and published as standard track Request For Comment (RFC) documents. RFC 959 documents the File Transfer Protocol (FTP), which is used for file transfer between a client and a server, and for remote management of files on a server. The Internet draft document "Securing FTP with TLS" describes a mechanism that can be used by FTP clients and servers to implement security and authentication using the TLS protocol defined by RFC 2246 and the extensions to the FTP protocol defined by RFC 2228. RFC 1945 documents Version 1.0 of the HyperText Transfer Protocol (HTTP), and RFC 2616 documents Version 1.1 of the protocol. These standards govern the communication of client applications such as browsers with web servers. The File Transfer Control implements the GET and PUT commands of these standards.
• Features and Stability
  The Catalyst File Transfer control is built on the solid foundation of the award-winning SocketTools family of products. The same core technologies and features that have been market-tested and proven since 1995 were used to create the File Transfer control. As a leading developer of Internet component software, tens of thousands of developers around the world trust Catalyst Development to create components with the stability and features needed to build dependable, world-class software.
• Flexibility
  The File Transfer control has been designed with a great degree of flexibility and can be used with a wide variety of programming languages and different types of development environments. Implemented as a standard ActiveX control, it is fully supported by languages such as Visual Basic, Visual FoxPro, Visual C++, Borland C++Builder, Delphi and PowerBuilder. In addition, the control can also be used as a basic COM object in scripting languages like VBScript, with full support for server-side scripting in Active Server Pages and other similar technologies.
• Simplified Redistribution
  Created using the ActiveX Template Library, the Catalyst File Transfer control has no dependency on third-party components or Microsoft support libraries. This means that only the control itself needs to be included with the program that uses it, simplifying the process of redistributing and installing the software while reducing the application's overall size.
• Documentation
  As important as functionality, features and stability are, comprehensive documentation is equally as important to the application developer. This is why the Catalyst File Transfer product includes a Developer's Guide which provides an overview of the product, a QuickStart Guide to help the developer get started and ease the learning curve, and a complete Technical Reference which documents every property, method and event supported by the control. A printable version of the documentation is included with the product, as well as context-sensitive online help which can be accessed directly from within the development environment. Example programs in a variety of languages are also included to help the developer become familiar with the features of the control and provide code which they can re-use in their own applications.
