计时器组件未停止

2024-05-19 • 问答

我正在使用Winforms应用程序，我打算在用户单击它时使标签“滑行”。为此，我创建了一个click事件，该事件启动了一个计时器，该计时器随后将标签逐渐移至窗体上方。然后，我有了一个递增的计数器，当计数器到达某个位置时，计时器应该停止。但是，计时器没有停止。为了测试目的，我故意将计数器限制设置为2，但是标签继续从表格中移开。这是代码：

//example 1
const xd = new Observable(({ next }) => {
  next("3");
});

xd.subscribe(msg => console.log(msg));

//example 2
    const obs$ = new Observable();

    obs$.subscribe(mg => console.log(mg));

//example 3
 private socket: SocketIOClient.Socket;
  constructor(private url: string) {
    this.socket = io(this.url);
  }

  listen() {
    return new Observable(({ next }) => {
      this.socket.on("message",next)
    })
  }

int counter = 0; // here you are setting it 0 newsLabel.Top -= 10; counter++; // here you are incrementing it by 1 if (counter == 2) // here you are checking for 2,its never going to get there drawerTimer.Stop();

private int _counter; // instance field,field to remember your count private void DrawerTimer_Tick(object sender,EventArgs e) { newsLabel.Top -= 10; counter++; // increment it every tick if (counter == 2) drawerTimer.Stop(); } private void News_Click(object sender,EventArgs e) { _counter = 0; // set to zero when start drawerTimer.Start(); }
