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; //处理事件()
msecs := Tick - GetTickcount;
end;
finally
CloseHandle(Event);
