public class WMScript : IDisposable
public ref class WMScript : public System.IDisposable
The WMScript class exposes a Windows Media script management interface, useful for adding and removing script commands in the WMV video format. The CaptureCtrl and ConvertCtrl objects use this object to allow the insertion of header and stream-based scripts. A WMScript object cannot be created externally and is only obtained through the parent object's interface. To get this interface, call either CaptureCtrl.WMScripter or ConvertCtrl.WMScripter. See the Microsoft documentation, Using Script Commands Supported by Windows Media Player, for a complete list of script commands supported by Windows Media Player.
