Remarks

Indicates the number of DataEvents queued for the bump bar unit specified by the CurrentUnitId property.

An application can interrogate BumpBarDataCount to determine whether additional input is queued from a bump bar unit but has not yet been delivered because of other application processing, freezing of events, or other causes.

BumpBarDataCount is typically initialized to zero by the Open method. It should then be kept current by the service object while the device is enabled.
