Represents the type of the service.
This enumeration supports a bitwise combination of its member values.

- Attributes
Fields
| Name | Value | Description |
|---|---|---|
| KernelDriver | 1 | A Kernel device driver such as a hard disk or other low-level hardware device driver. |
| FileSystemDriver | 2 | A file system driver, which is also a Kernel device driver. |
| Adapter | 4 | A service for a hardware device that requires its own driver. |
| RecognizerDriver | 8 | A file system driver used during startup to determine the file systems present on the system. |
| Win32OwnProcess | 16 | A Win32 program that can be started by the Service Controller and that obeys the service control protocol. This type of Win32 service runs in a process by itself. |
| Win32ShareProcess | 32 | A Win32 service that can share a process with other Win32 services. |
| InteractiveProcess | 256 | A service that can communicate with the desktop. |
Examples
The following example uses the ServiceController class to display the device driver services on the local computer.
array<ServiceController^>^scDevices = ServiceController::GetDevices();
if ( scDevices->Length )
{
int numAdapter = 0,numFileSystem = 0,numKernel = 0,numRecognizer = 0;
// Display the list of device driver services.
Console::WriteLine( "Device driver services on the local computer:" );
for each (ServiceController^ scTemp in scDevices)
{
// Display the status and the service name, for example,
// [Running] PCI Bus Driver
// Type = KernelDriver
Console::WriteLine( " [{0}] {1}", scTemp->Status, scTemp->DisplayName );
Console::WriteLine( " Type = {0}", scTemp->ServiceType );
// Update counters using the service type bit flags.
if ( (scTemp->ServiceType & ServiceType::Adapter) != (ServiceType)0 )
{
numAdapter++;
}
if ( (scTemp->ServiceType & ServiceType::FileSystemDriver) != (ServiceType)0 )

}
if ( (scTemp->ServiceType & ServiceType::KernelDriver) != (ServiceType)0 )
{

}
if ( (scTemp->ServiceType & ServiceType::RecognizerDriver) != (ServiceType)0 )
{
numRecognizer++;

Console::WriteLine( "Total of {0} device driver services", scDevices->Length.ToString() );

Console::WriteLine( " {0} are file system drivers", numFileSystem.ToString() );

Remarks
The service type indicates how the service is used by the system. The ServiceController that passes commands to the service stores a value for the service type.
The value of a ServiceType instance represents a set of flags combined using the bitwise OR operator.
The creation of interactive services is not supported. To workaround this, you can create a non-interactive service and a separate control GUI application that communicates with the service using sockets or remoting.
