(九)使用自定义光标,QQ截图时的光标

(十)在截图中包含鼠标指针形状

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();
        }
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
        /// <summary>
        /// 截图时是否显示截图信息栏
        /// </summary>
        public bool InfoBoxVisible = true;

        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
        /// <summary>

        /// 自动保存文件名序号
        /// </summary>
        public int autoSaveFileIndex = 0;
        #endregion 自动保存参数

添加“AppSettingKeys”类:

/// <summary>
    /// 提供配置文件中AppSettings节中对应的Key名称
    /// </summary>
    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";

    }

Program.cs文件添加枚举类型:

/// <summary>
    /// 控制键的类型
    /// </summary>
    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
