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

Syntax

'Declaration
Public Event DeviceAddedEvent As DeviceChangedEventHandler

public event DeviceChangedEventHandler DeviceAddedEvent

public:
event DeviceChangedEventHandler^ DeviceAddedEvent {
    void add (DeviceChangedEventHandler^ value);
    void remove (DeviceChangedEventHandler^ value);
}

/** @event */
public void add_DeviceAddedEvent (DeviceChangedEventHandler value)

/** @event */
public void remove_DeviceAddedEvent (DeviceChangedEventHandler value)

Example

The following example demonstrates how an application might handle a DeviceAddedEvent event:

posExplorer.DeviceAddedEvent += new (DeviceChangedEventHandler(OnDeviceAdded);

Msr msr;
private void OnDeviceAdded(object source, DeviceChangedEventArgs e)
{
      if (e.Device.Type == DeviceType.Msr)
         Msr = (Msr) posExplorer.CreateInstance(e.Device);

}

Remarks

DeviceAddedEvent only notifies for POS devices for which there is a service object installed.

The event handler receives an argument of type DeviceChangedEventArgs which contains a DeviceInfo object for the added device.
