上一篇：C#软件开发实例.私人订制自己的屏幕截图工具（五）针对拖拽时闪烁卡顿现象的优化
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：
///
/// 保存Form1的句柄
///
private IntPtr frm1Handle = IntPtr.Zero;修改构造函数：
///
/// 构造函数
///
///
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：
///
/// 托盘菜单设置事件处理程序
///
///
///
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：
#region 基本设置参数
///
/// 截图时是否显示截图信息栏
///
public bool InfoBoxVisible = true;
///
/// 截图时是否显示编辑工具栏
///
public bool ToolBoxVisible = true;
///

public bool IsCutCursor = true;
///
/// 截图时是否显示放大镜

///
/// 放大镜的尺寸——宽度
///
public int ZoomBoxWidth = 120;
///
/// 放大镜的尺寸——高度
///
public int ZoomBoxHeight = 100;
#endregion
#region 图片上传参数
public string PicDescFieldName = "pictitle";
public string ImageFieldName = "upfile";
public string PicDesc = "cutImage";
public string UploadUrl = "http://";
public bool DoUpload = false;
#endregion
#region 自动保存参数
///

///
public bool AutoSaveToDisk = false;
///

///
/// 自动保存文件格式：.png, .jpg, .jpeg, .gif, .bmp
///
public string AutoSaveFileName3 = ".png";
///
/// 自动保存文件名序号
///
public int autoSaveFileIndex = 0;
#endregion 自动保存参数添加“AppSettingKeys”类：
///
/// 提供配置文件中AppSettings节中对应的Key名称
///
public static class AppSettingKeys
{
//基本设置
public static string HotKeyMode = "HotKeyMode";
public static string InfoBoxVisible = "InfoBoxVisible";
public static string ToolBoxVisible = "ToolBoxVisible";
public static string ZoomBoxVisible = "ZoomBoxVisible";
public static string ZoomBoxWidth = "ZoomBoxWidth";

public static string AutoSaveDirectory = "AutoSaveDirectory";
public static string AutoSaveFileName1 = "AutoSaveFileName1";
public static string AutoSaveFileName2 = "AutoSaveFileName2";
public static string AutoSaveFileName3 = "AutoSaveFileName3";
}Program.cs文件添加枚举类型：
///
/// 控制键的类型
///
public enum KeyModifiers : uint
{
None = 0,
Alt = 1,
Control = 2,
Shift = 4,
Windows = 8
}警告：由于xxx是引用封送类的字段，访问上面的成员可能导致运行时异常
