Elements
- MQE_EVENT_NETWORKAVAILABLE
Indicates that the media query ending is connected to a network. The media query engine sends this message when it finds a network during startup and upon reconnection after a period of lost connectivity. This message can only be sent if the devices network adapter supports Media Sense.
- MQE_EVENT_NETWORKNOTAVAILABLE
