请教控件 progressBar1和trackBar1问题。

Question

public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }        private void timer1_Tick(object sender, EventArgs e)
        {           
         if (progressBar1.Value<=90) 
         progressBar1.Value = progressBar1.Value + 10;
        else if (progressBar1.Value == 100)
         progressBar1.Hide();
         }
        private void trackBar1_Scroll(object sender, EventArgs e)
        {
            progressBar1.Value = trackBar1.Value;
        }
请问下为什么这样写那个trackBar1控件不随者控件 progressBar1一起动？

Answer 1

Timer有什么用？trackBar1_Scroll应该没问题
try
private void trackBar1_Scroll(object sender, EventArgs e)
        {
            progressBar1.Value = trackBar1.Value;
            if (progressBar1.Value == 100)
                progressBar1.Hide(); 
        }

Answer 2

那个Timer是让progressBar控件自己动啊 
然后让trackBar控件跟着那个progressBar控件一起动。

Answer 3

不用timer progressBar1也会动的，因为你在trackBar1_Scroll把trackBar1的值赋给了progressBar1
private void trackBar1_Scroll(object sender, EventArgs e) 
        { 
            progressBar1.Value = trackBar1.Value; 
            if (progressBar1.Value == 100) 
                progressBar1.Hide();  
            else
                progressBar1.Show(); 
        }

Answer 4

对不起啊，我发现我好像搞错了，应该是那个trackBar跟着那个progressBar动而不是你动那个trackBar那个progressBar动。      
       
        private void timer1_Tick(object sender, EventArgs e) 
        {            
         if (progressBar1.Value <=90)  
         progressBar1.Value = progressBar1.Value + 10; 
        else if (progressBar1.Value == 100) 
         progressBar1.Hide(); 
         } 
        private void trackBar1_Scroll(object sender, EventArgs e) 
        { 
             trackBar1.Value= progressBar1.Value; 
        } 

Answer 5

我是想把progressBar的值赋给TrackBar。而不是把TrackBar的值赋给progressBar。

Answer 6

 谢谢啊我现在知道了应该把trackBar1.Value = progressBar1.Value;
写在那个Time控件中。
   private void timer1_Tick(object sender, EventArgs e)  
        {             
        if (progressBar1.Value <= 90)
            {
                progressBar1.Value = progressBar1.Value + 10;
                trackBar1.Value = progressBar1.Value;
            }
            else if (progressBar1.Value == 100)
             progressBar1.Hide(); 

Answer 7

private void trackBar1_Scroll(object sender, EventArgs e) 
        { 
            progressBar1.Value = trackBar1.Value; 
        } 
这个根本是多余的,而且没有任何用处

Answer 8

不是啊放在那里你动那个trackBar，那个progressBar会跟着动啊 ，第1个代码。
