用MFC打造自定义屏幕右下角弹出窗口 MFC（Microsoft Foundation Classes）是一个为简化Windows程序开发而设计的C++类库。在MFC中，弹出窗口是一种常见的用户界面元素，用于显示额外信息或进行交互，如消息框、文件对话框等。MFC通过封装Windows API，简化了弹出窗口的创建、管理等操作，使其与应用程序的其他部分集成更加自然。当标准样式无法满足特定需求时，开发者可以使用自定义样式。自定义样式允许开发者通过修改窗口类的扩展样式和窗口过程函数来实现独特的界面设计和交互逻辑。阅读详情

微软的每一个产品，无论功能还是界面设计都会带给我们一定的惊喜，比如OfficeXP、Office2003、Messenger的界面设计，早已成为众多软件竞相模仿的对象，就拿Messenger来说，我就见过好几套网络视频会议的软件都借鉴了它的界面风格。
　　前段时间因为要在原来的软件上增加一个快捷键提示窗体，这个提示窗要求在显示的时候比较醒目美观能引起用户注意，显示后不影响用户操作，能够关掉。很自然的就想到了Messenger那个从屏幕右下角逐渐弹出的消息提示窗体，不过相对Messenger我更喜欢QQ2004奥运版的配色风格，反正都是偷就多偷点吧，下面快捷键提示窗的最终效果：
　　　　快捷键提示窗样式

　　这个窗体有以下几个特点：
　　1、显示的时候是从屏幕右下角逐渐弹出的；
　　2、它是个无标题窗体，但它必须允许用户移动和改变大小，因此要用到无标题窗体拖动、改变大小的技术；
　　3、它是个不规则的窗体，主要是左上角和右上角是圆形导角，因此要为窗体创建外形，且窗体改变大小时必须重建；
　　4、它标题和内容显示区都有渐层色，标题还有几个小点点，在实现时使用取巧的方法，直接利用截图进行填充。

　　当然界面可以偷，代码就得老老实实的写的了，下面是界面设计图和实现代码：
