I need a way to change the service parameters like SERVICE_EXIT_CODE value to 2 other than 0.

Plz see the description below.

In command prompt by typing
sc query themes

Displays:
SERVICE_NAME: themes
        TYPE               : 20  WIN32_SHARE_PROCESS
        STATE              : 4  RUNNING
                                (STOPPABLE, NOT_PAUSABLE, ACCEPTS_SHUTDOWN)
        WIN32_EXIT_CODE    : 0  (0x0)
        SERVICE_EXIT_CODE  : 0  (0x0)
        CHECKPOINT         : 0x0
        WAIT_HINT          : 0x0

I want to change these parameters(ex: WIN32_EXIT_CODE value to -223 or any other value).
FYI: (There is a structure SERVICE_STATUS which takes care of these values.)
I need a program in C++  to achieve it.

The service exit code is the return value of an service when terminating. The service can set it to the SERVICE_STATUS structure associated with the service by calling SetServiceStatus passing the handle to the updated structure. If you would write 2 or -223 to the dwCurrentState member of that structure, the Service Control Manager surely would reflect that status.

Below is sample code how a service sets its current status.  

The full sample can be found at http://support.microsoft.com/kb/201349/en-us

If your sservice stops or was stopped by SCM (Service Control Manager) you would set your status to the code you want. Try to not match to status code which have a different meaning, e. g. SERVICE_START_PENDING

Here are the codes for predefined status values

//
// Service State -- for CurrentState
//
#define SERVICE_STOPPED                0x00000001
#define SERVICE_START_PENDING          0x00000002
#define SERVICE_STOP_PENDING           0x00000003
#define SERVICE_RUNNING                0x00000004
#define SERVICE_CONTINUE_PENDING       0x00000005
#define SERVICE_PAUSE_PENDING          0x00000006
#define SERVICE_PAUSED                 0x00000007


      // Register the ServiceHandler() function to receive control requests.
      hService = RegisterServiceCtrlHandler( SERVICE_NAME,
            ServiceHandler );
 
      // Set service status to start pending.
      ss.dwCurrentState = SERVICE_START_PENDING;
      ss.dwCheckPoint = 1; 
      ss.dwWaitHint = 500;
      SetServiceStatus( hService, &ss );
 
      // TODO: add additional initialization code here.
 
      // set service status to running
      ss.dwCurrentState = SERVICE_RUNNING;
      ss.dwCheckPoint = ss.dwWaitHint = 0;   
      SetServiceStatus( hService, &ss );
