Routine Description:
Stub for calling CreateService. If CreateService fails with
the error code indicating that the service already exists, this routine
calls the routine for ChangeServiceConfig to ensure that the
parameters passed in are reflected in the services database.
Arguments:
ServiceName - Name of service
DisplayName - Localizable name of Service or ""
ServiceType - Service type, e.g. SERVICE_KERNEL_DRIVER
StartType - Service Start value, e.g. SERVICE_BOOT_START
ErrorControl - Error control value, e.g. SERVICE_ERROR_NORMAL
BinaryPathName - Full Path of the binary image containing service
LoadOrderGroup - Group name for load ordering or ""
Dependencies - MultiSz list of dependencies for this service. Any dependency
component having + as the first character is a group dependency.
The others are service dependencies.
ServiceStartName - Service Start name (account name in which this service is run).
Password - Password used for starting the service.
Return value:
Boolean value indicating outcome.
