The Internet Control Message Protocol (ICMP) is commonly used to determine if a remote host is reachable and how packets of data are routed to that system. Users are most familiar with this protocol as it is implemented in the ping and traceroute command line utilities. The ping command is used to check if a system is reachable and the amount of time that it takes for a packet of data to make a round trip from the local system, to the remote host and then back again. The traceroute command is used to trace the route that a packet of data takes from the local system to the remote host, and can be used to identify potential problems with overall throughput and latency. The control can be used to build in this type of functionality in your own applications, giving you the ability to send and receive ICMP echo datagrams in order to perform your own analysis.


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 or Visual C++ 6.0, it is required that you have Service Pack 6 (SP6) installed. It is recommended that you install all updates for your development tools.

This component is supported on Windows XP and later versions of the Windows desktop and server platforms. If you are using Windows XP, you must have Service Pack 3 (SP3) installed as a minimum requirement. It is recommended that you install the current service pack and all critical updates available for your version of 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 XP Professional, Windows Server 2003 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.
