1.窗体与界面设计-窗体效果

029 制作鼠标穿透窗体
在对桌面进行操作时，为了使桌面更加美观，可以在桌面的上面加一层类似于玻璃的效果，用户可以用鼠标透过“玻璃”对桌面进行操作。本实例通过使用鼠标穿透窗体类实现以上功能。主要用到了 API 函数 SetWindowLong 和 GetWindowLong。
1.创建一个项目，默认窗体为 Form1，将该窗体的 FormBordeStyle 属性设置为 None，BackColor 属性设置为 Gainsboro，Opacity 属性设置为 60%，WindowState 属性设置为 Maximized。
2.在 Form1 窗体中添加一个 NotifyIcon 控件，并设置其 Icon 属性为指定的图标，显示提示信息；添加一个 ContextMenuStrip 控件，作为程序的快捷菜单。

030 窗体换肤程序
本实例的基本原理是给窗体的各个组成部分更换图片，基于该原理，首先需要分析窗体的组成部分，主要包括标题栏、左边框、右边框、下边框、窗体中间区域及可能存在的菜单栏，其中标题栏和3个边框无法通过设置相关属性来达到更换背景图片的目的。对于这个问题，可以通过取消窗体的 FormBorderStyle 属性，同时在标题栏和3个边框的位置添加 Panel 控件来解决，然后通过选择不同的皮肤类型，为窗体的各个组成部分设置图片，最终达到窗体换肤的效果。在以上过程中，最主要的技术问题是如何从指定的文件创建 Image 对象，以及如何获取图片的路径。
1.创建一个项目，默认窗体为 Form1，设置 Form1 的 AutoscaleMode 属性为 Inherit，DoubleBuffered 属性为 True，IsMdiContainer 属性为 True。
2.在窗体中添加6个 Panel 控件，分别用来作为窗体的标题栏、下边框、左边框、右边框、左下角边框和右下角边框；添加一个 ContextMenuStrip 控件，用来作为更换皮肤的快捷菜单；添加3个 PictureBox 控件，分别用来显示最大化、最小化和关闭图片。
