现在，您可以看到他的代码包含一个延迟字段、一个文本字段和“开始”/“停止”按钮。
所以我试着做一些类似的事情，这是代码：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Threading;
namespace Spammer
{
public partial class Form1 : Form
{
int delay, y = 1;
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
delay = int.Parse(textBox2.Text);
timer1.Interval = delay;
timer1.Start();
}
private void textBox1_TextChanged(object sender, EventArgs e)
{
}
private void button2_Click(object sender, EventArgs e)
{
timer1.Stop();
}
private void send()
{
}
private void label1_Click(object sender, EventArgs e)
{
}
private void textBox2_TextChanged(object sender, EventArgs e)
{
}
private void timer1_Tick(object sender, EventArgs e)
{
if (this.Focused)
{
return;
}
SendKeys.Send(textBox1.Text);
}
}
}
现在，我昨天发布了一个类似的问题，但这个问题要准确得多。
在他的程序中，我输入了一些文本，选择了 10MS 的延迟并启动它。发送几秒钟后，我点击了他程序中的“停止”按钮，它立即停止发送密钥。
现在...当我运行我的程序并开始发送密钥（有 10 毫秒延迟）时，我让它运行了几秒钟，然后按了“停止”。什么也没发生，“停止”甚至没有点击。它只是在它周围显示了一个蓝框，我无法单击它。
当然，正因为如此，它并没有停止发送密钥。
那么，为什么它在他的程序中运行良好，但在我的程序中却完全不起作用？
