vc++啟動和停止服務

包含頭文件：#include <winsvc.h>
以下以web服務為例：

#include <winsvc.h>
void CStartServiceDlg::OnBnClickedButton1()
{
       // 打開服務管理對象
    SC_HANDLE hSC = ::OpenSCManager( NULL,
                        NULL, GENERIC_EXECUTE);
    if( hSC == NULL)
    {
        TRACE( "open SCManager error");
        return;
    }
    // 打開www服務。
    SC_HANDLE hSvc = ::OpenService( hSC, "W3SVC",
        SERVICE_START | SERVICE_QUERY_STATUS | SERVICE_STOP);
    if( hSvc == NULL)
    {
        TRACE( "Open www erron。");
        ::CloseServiceHandle( hSC);
        return;
    }
    // 獲得服務的狀態
    SERVICE_STATUS status;
    if( ::QueryServiceStatus( hSvc, &status) == FALSE)
    {
        TRACE( "Get Service state error。");
        ::CloseServiceHandle( hSvc);
        ::CloseServiceHandle( hSC);
        return;
    }
    //如果處於停止狀態則啟動服務，否則停止服務。
    if( status.dwCurrentState == SERVICE_RUNNING)
    {
        // 停止服務
        if( ::ControlService( hSvc,
          SERVICE_CONTROL_STOP, &status) == FALSE)
        {
            TRACE( "stop service error。");
            ::CloseServiceHandle( hSvc);
            ::CloseServiceHandle( hSC);
            return;
        }
        // 等待服務停止
        while( ::QueryServiceStatus( hSvc, &status) == TRUE)
        {
            ::Sleep( status.dwWaitHint);
            if( status.dwCurrentState == SERVICE_STOPPED)
            {
                AfxMessageBox( "stop success。");
                ::CloseServiceHandle( hSvc);
                ::CloseServiceHandle( hSC);
                return;
            }
        }
    }
    else if( status.dwCurrentState == SERVICE_STOPPED)
    {
        // 啟動服務
        if( ::StartService( hSvc, NULL, NULL) == FALSE)

      }
    }
