The following example uses the ServiceController class to display the device driver services on the local computer.

      //   [Running] PCI Bus Driver

Remarks

GetDevices returns only the device driver services from the local computer. To retrieve the non-device driver services or services that are not drivers, call the GetServices method. Together, the two methods provide access to all the services on a computer.

Public Shared Function GetDevices (machineName As String) As ServiceController()
Parameters
machineName
String String String String

Returns

An array of type ServiceController in which each element is associated with a device driver service on the specified computer.

Exceptions

An error occurred when accessing a system API.

The machineName parameter has invalid syntax.
