This function is called to load a service.

Syntax

HANDLE ActivateService(
  LPCWSTR lpszDevKey,
  DWORD dwClientInfo
);

Parameters

  • lpszDevKey
    [in] Pointer to the string that contains the name of the service to load. Information concerning the service's DLL name and other parameters is specified in the registry key HKEY_LOCAL_MACHINE\Services\lpszDevKey.

Return Value

A handle to the service is returned on success. A NULL value is returned on failure. For extended error information, call GetLastError.

Remarks

Once ActivateService has been called, Servicesd.exe retrieves information about the service in HKEY_LOCAL_MACHINE\Services\lpszDevKey and loads the service as if it were being loaded upon system initialization.

For more information about setting up a service registry key for ActivateService or for use at system initialization, see Servicesd.exe Registry Settings.
