Remarks

Indicates the total number of currently queued DataEvent events at the service object. All online units are included in this value.

The application can interrogate the DataCount property to determine whether additional input is queued from a device but has not yet been delivered because of other application processing, freezing of events, or other causes.

The DataCount property is set and kept current by the service object while the device is enabled.
