//延遲函式:方法一 procedure delay(msecs:integer); var Tick: DWord; Event: THandle; begin Event := CreateEvent(nil, False, False, nil); try Tick := GetTickCount + DWord(msecs); while (msecs > 0) and (MsgWaitForMultipleObjects(1, Event, False, msecs, QS_ALLINPUT) <> WAIT_TIMEOUT) do begin Application.ProcessMessages; msecs := Tick - GetTickcount; end; finally CloseHandle(Event); end; //延遲函式:方法二 procedure Delay(dwMilliseconds:DWORD);//Longint var iStart,iStop:DWORD; begin iStart := GetTickCount; repeat iStop := GetTickCount; Application.ProcessMessages; until (iStop - iStart) >= dwMilliseconds; end;
