Device Class
Represents a device or emulator that is based on Windows Embedded CE and provides methods to provision, get information, and connect to a device.
Namespace: Microsoft.SmartDevice.Connectivity
Assembly: Microsoft.SmartDevice.Connectivity (in Microsoft.SmartDevice.Connectivity.dll)
Syntax
'Declaration
Public Class Device
'Usage
Dim instance As Device
public class Device
public ref class Device
public class Device
Remarks
In the Datastore, every device belongs to a platform. For example, the Windows Mobile 5.0 Pocket PC R2 Square Emulator belongs to the Windows Mobile 5.0 Pocket PC platform.
This class does not have any constructors. To get an instance, use GetDevice or GetDevices.
Examples
This example connects to an emulator, writes information about the emulator to the console, queries the emulator for current security policies, and then provisions the emulator with two-tier prompt security configuration.
