如果谁需要Windows Media Player SDK或Service SDK，可以向索取，
当然也可以自己到Microsoft站点去downlaod回来。
What's New for the Windows Media Player Control?
New multimedia functionality has been added to the
Microsoft? Windows Media? Player control since its last
release. These changes are valid for versions of the Windows
Media Player control available in Microsoft? Internet Explorer
5, the Microsoft? Windows? 98 OEM Service Release (OSR), and
Microsoft? Windows 2000.
The Windows Media Player control now supports playback of
Digital Video Disc (DVD) media. Microsoft has included
scripting support for nearly all DVD-specific capabilities,
such as title and chapter seeking, video angle changes, and
multi-language support. The added features and scripting
support are listed in detail in Using DVD with the Windows
Media Player Control.
The Windows Media Player control now also supports playback
for Compact Disc (CD) audio. By specifying CDAUDIO: for the
input filename, you can play an entire CD as if it were a
single audio stream. The Windows Media Player control treats
individual tracks of the CD as markers within the audio stream.
For more information, see Compact Disc Audio Playback.
Microsoft has made all Windows Media Player functionality
available to web scripting languages such as Microsoft? Visual
Basic? Scripting Edition and Microsoft? JScript?. This enables
you to embed the Windows Media Player control in HTML
applications and create custom faceplates for your multimedia
presentations. You can create an entire user interface on a
faceplate that is tailored for the media you are presenting.
The Faceplate Authoring Guide walks you through the process of
creating a faceplate, and provides sample code demonstrating
the concepts discussed.
As part of the new faceplate functionality, Microsoft has
added script support for accessing information contained in
Advanced Stream Redirector files (ASX) files and embedding as
much custom information within each media file as you like. The
Windows Media Player control reads the information from the ASX
file, and scripts can then retrieve the information and display
it on a faceplate.
The following scripting and ASX elements are new to this
release of the Windows Media Player control.
ASX Elements
PARAM Element ? Defines a custom parameter associated with
a clip or show.
Scripting Methods
GetCurrentEntry ? Retrieves the current clip being played
by the Windows Media Player control.
GetMediaParameter ? Retrieves the value of the specified
parameter for an indexed ASX entry.
GetMediaParameterName ? Retrieves the name of the
specified parameter for an indexed ASX entry.
SetCurrentEntry ? Selects a clip for playback by the
Windows Media Player control.
ShowDialog ? Displays a modal dialog box containing a
specified Windows Media Player dialog.
Scripting Properties
EntryCount ? Retrieves the number of entries contained in the
current ASX file.
