If/else调用控件
本文关键字：控件 调用 else If | 更新日期: 2023-09-27 18:11:29
我是一个初学者，希望有人能告诉我，如果我使用正确的方式来使用if/else，而使用线程。
在我的表单用户有一个复选框，这将决定哪一组应用程序将被安装。如果用户选择无线启用，它将安装奥德赛客户端。
请不要生吃我，我才刚刚开始。
所以问题是:
-
上的if/else语句是最好的方式?
-
如何调用复选框控件?我知道如何通过调用来使进度条工作，但对复选框感到困惑。
- 这是最好的方式来挂钩进度条考虑到我正在处理wceload>?或者有可能将它与我们的预设值连接起来。即25;35% ?
谢谢Program1

我重新编写了代码…看看现在是否更有意义:

}
else
{

this.progressBar1.Value = percent;
}
}
public delegate bool IsCheckedDelegate(CheckBox cb);
public bool IsChecked(CheckBox cb)
{
if (cb.InvokeRequired)
{
return (bool)cb.Invoke(new IsCheckedDelegate(IsChecked), new Object[] { cb });
}
else
{
return cb.Checked;
}
}
private void button1_Click_1(object sender, EventArgs e)
{
if (myThread == null)
{
button1.Enabled = false;
myThread = new Thread(MyWorkerThread);
myThread.IsBackground = true;
myThread.Start();
}
}

appcenter();
