This ActiveX control provides an interface for implementing an embedded, lightweight server that can be used to exchange files with a client using the standard File Transfer Protocol. The server can accept connections from any third-party application or a program developed using the SocketTools FTP ActiveX control.

The application specifies an initial server configuration by setting the relevant properties and can implement event handlers to monitor the activities of the clients that have connected to the server. The control automatically handles the standard FTP commands and requires minimal coding on the part of the application that is hosting the control. However, the application may also use event mechanism to filter specific commands or to extend the protocol by providing custom implementations of existing commands or add entirely new commands.

The server supports active and passive mode file transfers, has compatibility options for NAT router and firewall support, and provides support for secure file transfers using explicit SSL/TLS sessions. Secure connections require that a valid SSL certificate be installed on the system.


The SocketTools ActiveX Edition components are self-registering controls compatible with any programming language that supports COM (Component Object Model) and the ActiveX control specification. If you are using Visual Basic 6.0 you must have Service Pack 6 (SP6) installed. It is recommended that you install all updates for your development tools.

This control is supported on Windows 7, Windows Server 2008 R2 and later versions of the desktop and server platforms. If you are using Windows 7, you must have Service Pack 1 (SP1) installed as a minimum requirement. It is recommended that you install the current service pack and all critical updates available for the operating system.

This product includes both 32-bit and 64-bit ActiveX controls. Native 64-bit CPU support requires the latest 64-bit version of Windows 7, Windows Server 2008 R2 or later versions of the Windows operating system.


When you distribute an application that uses this control, you can either install the file in the same folder as your application executable or as a shared component in the appropriate system folder. If you install the control in the system folder, it is important that you distribute the correct version for the target platform and it must be registered. If you install the control in the same folder as your executable, it is recommended that you use registration-free activation or COM redirection to ensure that the correct version of the control is loaded by the application.
