而PictureBox控制項每隔0.1秒由右往左移動

當跑者跑出表單的左邊界

馬上又從表單的右邊界跑進來。

建立Timer控制項用來即時及產生動畫

加入HScrollBar控制項

該控制項可用調整跑者動畫速度。

請問HScrollBar如何調整跑者動畫速度？原程式碼using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;namespace picRunner{ public partial class Form1 : Form { public Form1() { InitializeComponent(); } int picNo = 0; PictureBox[] pics; private void Form1_Load(object sender
