WMRMRights.AllowTransferToSDMI

The AllowTransferToSDMI property specifies and retrieves a Boolean value that indicates whether the license allows the content to be transferred to SDMI-compliant portable devices or portable media that support Portable Device DRM version 1 or Windows Media DRM 10 for Portable Devices.

Syntax

WMRMRights.AllowTransferToSDMI = Boolean
Boolean = WMRMRights.AllowTransferToSDMI

Parameters

This property takes no parameters.

Return Values

If the property succeeds, it returns a Boolean value indicating whether the content can be transferred. If it fails, it returns E_FAIL, 0x80004005.

Remarks

The default value of this property is 0 (false).

In a purchase model, the AllowTransferToSDMI and AllowTransferToNonSDMI rights are typically used for allowing content to be transferred to devices.

However, in a subscription model, the AllowCopy right is usually enabled, which requires the use of devices based on Windows Media DRM 10 for Portable Devices.

Example Code

' Before you can issue a license, you must specify the consumer's
' rights and set them in the WMRMLicGen object.

' Declare objects.
    Dim sRights
    Dim RightsObj
    Dim LicGenObj

' Create objects.
    Set RightsObj = Server.CreateObject("Wmrmobjs.WMRMRights")
    Set LicGenObj = Server.CreateObject("Wmrmobjs.WMRMLicGen")

' Specify the rights that will be granted to the consumer.
    RightsObj.AllowBackupRestore = False
    RightsObj.AllowPlay = True
    RightsObj.AllowTransferToSDMI = True
    RightsObj.AllowTransferToNonSDMI = True
    RightsObj.TransferCount = 10
    RightsObj.BeginDate = "#20050101Z#"
    RightsObj.ExpirationDate = "#20051231Z#"
    RightsObj.DisableOnClockRollback = True

' Retrieve the string containing the rights.
    sRights = RightsObj.GetAllRights()

' Set the rights in the license generator.
    LicGenObj.Rights = sRights

' Continue the license issuing process.
