This property specifies how you wish to control the specified NT service. You must choose an option which is supported by the service you are controlling. For example, if you choose to pause a service, that service must be coded to allow itself to be paused. This means that the ServiceMain method call the Win32 API SetServiceStatus to tell the Service Control Manager that the service accepts pause and continue commands.

This property is passed to the Win32 API ControlService as the dwControl parameter.
