用模式窗体显示进度

[gaoqi9902]

我做了一个函数，在函数中我读取仪器的各个设置参数，这个函数处理的时间很长，主要是要调用底层的仪器驱动，我想在用户点击按钮以后弹出一个进度窗体，可以报告用户当前的程序正在读取哪个参数。

既然读取仪器数据的代码会写，这个小小的进度窗口能难倒你吗？加油

//from1代码

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Threading;

namespace WindowsApplication4
{
public partial class Form1 : Form
{
private Form2 frm= new Form2();
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
Thread th1 = new Thread(new ThreadStart(show));
th1.Start();

Thread th = new Thread(new ThreadStart(start));
th.Start();
}

private void Form1_Load(object sender, EventArgs e)
{

}
private void start()
{
frm.SetLableText("开始");
Thread.Sleep(3000);
frm.SetLableText("1");
Thread.Sleep(3000);
frm.SetLableText("结束");
}
private void show()
{
frm.ShowDialog();
}
}


//form2代码

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace WindowsApplication4
{
public partial class Form2 : Form
{
delegate void SetLableTextCallback(string str);
public Form2()
{
InitializeComponent();
}

public void SetLableText(string str)
{
if (label1.InvokeRequired)
{
SetLableTextCallback d = new SetLableTextCallback(SetLableText);
this.Invoke(d, new object[] { str });
}
else
{
label1.Text = str;
}
}
private void Form2_Load(object sender, EventArgs e)
{

}

}
}

//from1窗体有一个buuton,form2有一个lable,在lable显示提示
