# ServiceParameters

When an object is written as a Win32 service and installed for use by OLE through setting the LocalService named value under the AppID key, the ServiceParameters named-value can be set to pass the given parameter on the command line when the service is launched.

Registry Entry

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\APPID\
{AppID_value}\ServiceParameters = parameter

Remarks

The parameter value for the ServiceParameters named-value is any REG_SZ string value. This string is passed on the command line to the service as it is being launched.

For example, the following keys register the c:\mydb\mydb.exe executable to launch as the MyDatabase service when activated remotely. When launched as a service, the process receives “-Service” on its command-line.

    HKEY_CLASSES_ROOT\APPID\{c5b7ac20-523f-11cf-8117-00aa00389b71}\LocalService = MyDatabase

    HKEY_CLASSES_ROOT\APPID\{c5b7ac20-523f-11cf-8117-00aa00389b71}\ServiceParameters = -Service

Refer to the Win32 SDK documentation about services and the SECSVR sample Distributed COM application for more information about writing, installing, and debugging Win32 services.
