做过UG二次开发的都知道，在UG里做二次开发的主要界面就是对话框了，UG自己定义了一套二次开发的界面接口，即所谓的UIStyler，对于我们用惯了MFC及Windows的消息机制来说，它那点简单的事件映射，仅有的几个控件（好像连常用的树控件都没有）让我们没有发挥的余地。于是使用MFC对话框代替UG的对话框是每个从MFC进入UG二次开发的人的首先想法。关于怎么在UG中使用MFC对话框已经有文章讲过了，我这里就不再讲了。但MFC对话框的一个很大的缺点就是与UG对框的风格不统一。UG的对话框都具有统一的风格，首先，按钮都具有自己的风格，比如它的四个角是圆角，鼠标移到上面会显示一个Focus的框。然后它的所有对话框都是一级一级弹出来的，比如点击OK按钮，可能会弹出下一个对话框，而上一级对话框会隐藏掉，按Back按钮会重新返回到上一个对话框。再有，一旦有另外一个对话框弹出，当前的对话框都会隐藏或销毁。
下面就给出我的仿UG对话框风格的对话框类CHsPMEDialog，它除了实现了上面的三点UG风格外，由于UG似乎对键盘消息做了截获，如果是普通的MFC对话框，在UG内使用时一些特殊的功能键就无效了，比如TAB键、回车键、ESC都无效了。为此在我的类中，还使用了键盘钩子截获这几个按键消息并做出处理。

// CHsPMEDialog dialog
//-----------------------------------------------------------------------------
// 描述：此类可作为仿照UG UIStyler对话框的基类。它模仿了以下几种风格：
// 1、实现UG对话框的后退(Back)功能。实现方法为任何对话框在调出下一级
// (非模式)对话框时，先隐藏自身在需要返回上一级对话框时，根据其父窗口
// 指针将其显示出来，然后隐藏或销毁自身
// 2、实现类似UG "OK"、"Apply"、"Back"、"Cancel"等按钮的XP按钮风格效果。
// 采用的方法为使用上面的CHsPMEButton作为按钮的基类
// 3、由于UG系统对键盘消息的控制，使得某些键盘消息不能发送到MFC对话框，
// 如：TAB键，ESC键，ENTER键。而这些键对于对话框来说是很重要的。
// 采用的方法为键盘钩子，对本进程（即UG进程）的键盘消息进行截获。
// 4、实现非模态对话框类似UG风格，即只要其它对话框弹出来，上一个对话框
// 就自动销毁（隐藏）。采用CBT钩子方法截获窗口创建消息。
//-----------------------------------------------------------------------------
// 注意：
// 1、在构造对话框时必须给出其父窗口指针
// 2、在初始化基类时必须指定对话框资源模板ID
// 3、对话框资源中必须提供ID为IDC_BACK的按钮
// 4、派生类必须重写OnOK及OnCancel并且调用本基类的OnOK与OnCancel
