Installing a Service

A service configuration program uses the CreateService function to install a service in a SCM database. The following example shows how to install a service. The application-defined schSCManager handle must have SC_MANAGER_CREATE_SERVICE access to the SCManager object. For an example of how to do this, see Opening an SCManager database.

#include <windows.h>
#include <stdio.h>

BOOL CreateSampleService() 
{ 
    TCHAR szPath[MAX_PATH]; 
    
    if( !GetModuleFileName( NULL, szPath, MAX_PATH ) )
    {
        printf("GetModuleFileName failed (%d)/n", GetLastError()); 
        return FALSE;
    }
 
    schService = CreateService( 
        schSCManager,              // SCManager database 
        TEXT("Sample_Srv"),        // name of service 
        lpszDisplayName,           // service name to display 
        SERVICE_ALL_ACCESS,        // desired access 
        SERVICE_WIN32_OWN_PROCESS, // service type 
        SERVICE_DEMAND_START,      // start type 
        SERVICE_ERROR_NORMAL,      // error control type 
        szPath,                    // path to service's binary 
        NULL,                      // no load ordering group 
        NULL,                      // no tag identifier 
        NULL,                      // no dependencies 
        NULL,                      // LocalSystem account 
        NULL);                     // no password 
 
    if (schService == NULL) 
    {
        printf("CreateService failed (%d)/n", GetLastError()); 
        return FALSE;
    }
    else
    {
        CloseServiceHandle(schService); 
        return TRUE;
    }
}
