使服务程序像模像样

写windows的服务程序当然算不上什么高级编程，但是一般人可能不太注意服务程序的形象问题。打开服务管理器，服务名称就是程序名，更没有描述。看起来挺别扭。起始要使服务好看一点，只需要几步即可（以VC6为例）：

1. 将原来Install函数的CreateService调用改为

    SC_HANDLE hService = ::CreateService(
        hSCM,      // SC_HANDLE hSCManager,        handle to service control manager database  
        m_szServiceName,   // LPCTSTR   lpServiceName,     pointer to name of service to start       
        _T("世纪德润看护服务"),  // LPCTSTR   lpDisplayName,     pointer to display name                   
        SERVICE_ALL_ACCESS,   // DWORD     dwDesiredAccess,   type of access to service               
        SERVICE_WIN32_OWN_PROCESS, // DWORD     dwServiceType,     type of service                         
        SERVICE_AUTO_START,   // DWORD     dwStartType,       when to start service                   
        SERVICE_ERROR_NORMAL,  // DWORD     dwErrorControl,    severity if service fails to start      
        szFilePath,     // LPCTSTR   lpBinaryPathName,  pointer to name of binary file        
        NULL,      // LPCTSTR   lpLoadOrderGroup,  pointer to name of load ordering group
        NULL,      // LPDWORD   lpdwTagId,         pointer to variable to get tag identifier 
        _T("RPCSS/0"),    // LPCTSTR   lpDependencies,    pointer to array of dependency names    
        NULL,      // LPCTSTR   lpServiceStartName,pointer to account name of service  
        NULL);      // LPCTSTR   lpPassword         pointer to password for service account 

在::CloseServiceHandle(hSCM);以前添加：

  // Need to acquire database lock before reconfiguring.
  SC_LOCK sclLock = LockServiceDatabase(hSCM);
  if (sclLock != NULL)
  {
   // Open a handle to the service.
   SC_HANDLE hService = OpenService( 
    hSCM,     // SCManager database 
    m_szServiceName,  // name of service 
    SERVICE_CHANGE_CONFIG); // need CHANGE access

   if (hService != NULL)
   {
    SERVICE_DESCRIPTION sdBuf;
    sdBuf.lpDescription = _T("提供北京世纪德润科技有限公司服务程序的看护服务。");
    if (ChangeServiceConfig2 (
     hService, SERVICE_CONFIG_DESCRIPTION, &sdBuf))
    {
    // MessageBox(NULL, "Change SUCCESS", "", MB_SERVICE_NOTIFICATION); 
    }
    CloseServiceHandle(hService);
   }
   UnlockServiceDatabase(sclLock);
  }   

这就改了服务名称，添加了服务描述。

至于对于VS2003及以上，我喜欢从库里面拎出来相关部分，然后修改，类似于：

template <class T, UINT nServiceNameID>
class ATL_NO_VTABLE CDRAtlServiceModuleT : public CAtlExeModuleT<T>
