Question:

what do these variables mean:

SERVICE_CONTROL_USER128=28 ;User command 128
SERVICE_CONTROL_USER129=129 ;User command 129
SERVICE_CONTROL_USER130=130 ;User command 130
SERVICE_CONTROL_USER131=31 ;User command 131
SERVICE_CONTROL_USER255=255 ;User command 255 

Answer:

Services have the capability of accepting up to 128 different application-defined commands.

Windows calls these "user" commands in the sense that an user-written servcice is a "user" (and not the person)

Thus you can write a Winbatch service to "listen" to user defined commands.

The wntSvcControl function can send these commands to a service.
