Assembly: Microsoft.PointOfService (in microsoft.pointofservice.dll)

Usage

'Usage

Syntax

'Declaration
Public MustOverride ReadOnly Property DataCount() As Integer

public abstract int DataCount {get;}

public: property virtual Int32 DataCount{
    Int32 get();

public abstract int get_DataCount();

public abstract function get DataCount() : int;

Remarks

Indicates the total number of DataEvent events queued at the service object. All online units are included in this value. The number of queued events for a specific unit ID is stored in the BumpBarDataCount property.

The application can interrogate DataCount 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.

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