| Microsoft DirectX 9.0 |
Signals that the available set of IDvdControl2 interface methods has changed.
Parameters
lParam1
DWORD value that contains a combination of zero or more flags from the VALID_UOP_FLAG enumeration. The bits indicate which IDvdControl2 commands were explicitly disabled by the DVD disc.
lParam2
Zero.
Remarks
This event indicates only which operations are explicitly disabled by the content on the DVD disc. It does not guarantee that it is valid to call methods that are not disabled. For example, if no buttons are present, the IDvdControl2::ActivateButton method won't work, even though the method is not explicitly disabled.
This event is raised in all domains.
