在DLL工程里实现



      ULONG  WINAPI Thread1(LPVOID Param)

     {



             TCHAR Buffer[256];

             HDC hDC = GetDC(HWND_DESKTOP);

             int Step=1;

             MSG Msg;

              DWORD StartTick;

        //一个延时循环

             for(;Step<200;Step++)

             {

                        StartTick = GetTickCount();

                  /*这一段为线程交出部分运行时间以让系统处理其他事务*/

                       for(;GetTickCount()-StartTick<10;)

                         {

                                 if(PeekMessage(&Msg,NULL,0,0,PM_NOREMOVE) )

                                 {

                                   TranslateMessage(&Msg);

                                   DispatchMessage(&Msg);

                                   }

                           }
