ausprobier anwendung xD

int M = 0,S = 0, MS = 0;

void Increase( PVOID lParam  ){
 MS += 100;
 if ( MS >= 1000 ){
  MS = 0;
  if ( ++S >= 60 ){
    S = 0;
    M++;
  }
 }
}

void Output( PVOID lParam ){

  //cout << "Time: M,S,MS " << M << " : " << S << " : " << MS << endl;
  return;
}

int main(int argc, char* argv[])
{

  TimerManager * Man = new TimerManager();

  Man->AddTimer(100,Increase);
  Man->AddTimer(3000,Output);

  //Man->AddTimer(3000,MeineKlasse->TimerProcc,(PVOID)MeineKlasse);

  Sleep(1212000);
  delete Man;
  return 0;
}

Hi,

also habe gerade das problem das wenn ich den timer so schreibe wie er im moment ist, er warsch. durch den aufruf aus anderen threads probleme mit der konsolen ausgabe kriegt, kann ich dies durch eine explizite zuweisung des konsolen handles zu cout wieder beheben, und wenn, wie gehts sowas :D?

edit --

hat sich erledigt, der fehler lag in zeile 90, break vergessen ^.
