添加设置窗口
在解决方案资源管理器窗口中，右键单击项目名称，在弹出的菜单中选择：添加》Windows窗体：
输入窗体名称“frmSetup”：
设置窗体的Text属性为“设置”，设置窗体的Size为“472,276”，StartPosition属性为“CenterScreen”。
添加设置标签页：
左侧工具箱》窗器：双击“TabControl”
设置的Dock属性为“Top”，Size属性为“456,200”；
添加标签页：
添加三个标签页，Text分别设置为“基本设置，自动上传，自动保存”
添加确定和取消按钮；
基本设置标签页：
从工具箱中添加两个GroupBox，分别为“热键、截图选项”；
添加两个RadioButton，用于热键选择；
添加四个CheckBox用于截图选项；
添加两个TextBox用于设置放大镜的尺寸；
添加两个PictureBox用于显示X和锁的图片；
添加图片资源：
双击Properties中的“Resources.resx”
切换到图像视图：
将图片复制，粘贴到这里，分别命名为“Lock，X”；
设置PictureBox的Image属性为对应的资源：
自动上传标签页：
自动保存标签页：
其中文件名称需要使用两个ComboBox，Items集合分别设置为：
编写代码：
双击设置窗体，切换到代码视图，添加私有变量：
/// <summary>
/// 保存Form1的句柄
/// </summary>
private IntPtr frm1Handle = IntPtr.Zero;修改构造函数：
/// <summary>
/// 构造函数
/// </summary>
/// <param name="frm1_Handle"></param>
public frmSetup(IntPtr frm1_Handle)
{
InitializeComponent();
this.frm1Handle = frm1_Handle;
}为托盘菜单中的设置添加事件处理
打开主窗体Form1的设计视图，选中“contextMenuStrip1”
修改设置菜单的Name为“tsmi_Set”，双击设置菜单，添加代码：
/// <summary>
/// 托盘菜单设置事件处理程序
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void tsmi_Set_Click(object sender,EventArgs e)
{
frmSetup frm = new frmSetup(this.Handle);
frm.ShowDialog();
}添加项目引用：
主窗体添加相关配置项变量：
