About the Netshow Unicast Manager Control

The NetShow Unicast Manager control (Nsunimgr.ocx) is an ActiveX™ control used to monitor and supervise a NetShow unicast server. It administers the Unicast Manager Service and receives events from the NetShow Monitor Service. This SDK describes the functionality exposed by the control for creating custom administration and monitoring applications and integrating NetShow into other software products.

The Unicast Manager control exposes attrributes for performing the following tasks:

Setting and retrieving server properties such as the maximum aggregate bandwidth and the maximum number of clients.
Monitoring client behavior, including connections, disconnections, and files played.
Monitoring overall system activity, including server status, administration functions, and server limits.
Filtering the types of events received by the control.

The NetShow Unicast Manager control can be used directly in HTML pages (with or without Visual Basic Scripting) and in Visual Basic and Visual C++ applications. It exposes server administration functionality through a set of OLE automation interfaces. Those same properties and events are available in any programming environment that supports ActiveX controls. For more information on OLE automation and ActiveX controls, see any COM/OLE or ActiveX documentation. A list of additional information resources is in the More Information and Examples section of the NetShow Player Software Developer's Kit.

The properties exposed by the NetShow Unicast Manager control are run time properties; that is, they are not available at design time. The values of these properties can not be set or returned until the Connect method has completed succesfully. Some development tools, such as the Microsoft Visual Basic integrated development enviroment, do not display run time properties in their respective object browsers.

Support for current versions of the NetShow unicast server is limited to computers running Windows NT® Workstation or Windows NT Server version 4.0 operating systems; however, the Unicast Manager control is also supported on computers running Windows® 95.

The Unicast Manager control requires NSUNIMGR.OCX and NSOOBJ.DLL to be present and registered on the computer.
