MSDVDAdm Object

This component is available for use in the Microsoft Windows 2000, Windows XP, and Windows Server 2003 operating systems. It may be altered or unavailable in subsequent versions.

The methods and properties of the MSDVDAdm "administration" object enable a scripting application to modify its default settings in the Microsoft® Windows® registry. The registry is a database on all Windows systems where applications can store information about themselves to be used on initialization or during run time.

Most of these methods and properties do not set or retrieve the current values in the MSWebDVD object itself. This means, for example, that when you call GetParentalLevel the returned value is not the current parental level stored in the object. Rather, it is the default parental level stored in the registry. To get the current parental level, call the MSWebDVD method GetPlayerParentalLevel. Calling SaveParentalLevel simply writes a new default parental access level to the registry; you still need to call the MSWebDVD method SelectParentalLevel to make the change take effect immediately in the MSWebDVD object. The default locale identifier (LCID) methods work in a similar way.

On the other hand, the BookmarkOnStop and BookmarkOnClose methods take effect immediately because the MSWebDVD object checks these settings just before the user stops playback or closes the application, rather than during initialization.

You access the MSDVDAdm object through the DVDAdm property of MSWebDVD. So, for example, if the MSWebDVD object is named "DVD," call ChangePassword as shown in the following code example.

DVD.DVDAdm.ChangePassword(sUserName, sOld, sNew);
