Win32_CodecFile jscript sample code

The foundations for Manageability in Windows is Windows Management Instrumentation (WMI; formerly WBEM) and WMI extensions for Windows Driver Model (WDM).

ActiveXperts Network Monitor provides the ability to build monitor check routines based on WMI. ActiveXperts has collected more than a hundred WMI samples. You can use these samples as a base for new check routines you can write yourself. The Win32_CodecFile WMI class can be used in ActiveXperts Network Monitor to monitor your servers.

Description

The Win32_CodecFile WMI class represents the audio or video codec installed on the computer system. Codecs convert one media format type to another, typically a compressed format to an uncompressed format. The name codec is derived from a combination of compress and decompress. For example, a codec can convert a compressed format such as MS-ADPCM to an uncompressed format such as PCM, which most audio hardware can play directly.
