WMRMMeteringContent.KeyID
The KeyId property retrieves the key ID of the content item.
Syntax
String = WMRMMeteringContent.KeyID
Parameters
This property takes no parameters.
Return Values
If the property succeeds, it returns a String containing the key ID. If it fails, it returns a number in the error object.
Remarks
When recording metering data, the media player records the license key ID as a way to identify the content. So, to accurately meter content, you must protect each content item using a unique key ID.
This property is read-only.
