DirectInputDevice.Poll

The DirectInputDevice.Poll method makes data available from polled objects on a DirectInput device. If the device does not require polling, then calling this method has no effect. If a device that requires polling is not polled periodically, no new data will be received from the device. Calling this method causes DirectInput to update the device state, generate input events (if buffered data is enabled), and set notification events (if notification is enabled).

object.Poll()

Parameters

object

Object expression that resolves to a DirectInputDevice object.

Remarks

Before a device data can be polled, the data format must be set by using the DirectInputDevice.SetDataFormat or DirectInputDevice.SetCommonDataFormat method, and the device must be acquired by using the DirectInputDevice.Acquire method.
