This CLSID retrieves the status of door, liftgate, and trunk lid pin switches.
Door switches
Read, shareable or exclusive
| Type: | VT_UI4 (unsigned long bitmask) |
The following table shows possible door switches and their bitmask values. If a specified bit is set to 1, it indicates that the door associated with the switch is open.
