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;
登录后复制
修改构造函数：
- ///
/// 构造函数 /// /// public frmSetup(IntPtr frm1_Handle) { InitializeComponent(); this.frm1Handle = frm1_Handle; }
登录后复制
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(); }
登录后复制
编译，调试一下，通过托盘图标的右键菜单》设置 可以打开刚刚添加的设置窗口了。
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; ////// 截图中是否包含鼠标指针形状 /// public bool IsCutCursor = true; ////// 截图时是否显示放大镜 /// public bool ZoomBoxVisible = true; ////// 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 ////// 是否自动保存到硬盘 /// public bool AutoSaveToDisk = false; ////// 自动保存目录 /// public string AutoSaveDirectory = string.Empty; ////// 是否启用日期格式“2013_02_22”的子目录 /// public bool AutoSaveSubDir = false; ////// 自动保存文件名前缀 /// public string AutoSaveFileName1 = "屏幕截图"; ////// 自动文件名规则：日期时间，日期_序号，序号 /// public string AutoSaveFileName2 = "日期时间"; ////// 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
登录后复制
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 ZoomBoxHeight = "ZoomBoxHeight"; public static string IsCutCursor = "IsCutCursor"; //图片上传 public static string PicDescFieldName = "PicDescFieldName"; public static string ImageFieldName = "ImageFieldName"; public static string PicDesc = "PicDesc"; public static string UploadUrl = "UploadUrl"; public static string DoUpload = "DoUpload"; //自动保存 public static string AutoSaveToDisk = "AutoSaveToDisk"; public static string AutoSaveSubDir = "AutoSaveSubDir"; public static string AutoSaveDirectory = "AutoSaveDirectory"; public static string AutoSaveFileName1 = "AutoSaveFileName1"; public static string AutoSaveFileName2 = "AutoSaveFileName2"; public static string AutoSaveFileName3 = "AutoSaveFileName3"; }
登录后复制
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 }
登录后复制
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
