MFC 控件布局随窗口大小自动变化大小 位置
参考抄袭：
控件布局通用解决方案
在stdafx.h中增加代码，目的是在哪都容易调用

增加对话框的WM_SIZE消息处理函数
1 AUTO_SET_CONTROL_POS(IDC_xxx, LEFT_CHANGE_MODE_RATIO, RIGHT_CHANGE_MODE_RATIO, TOP_CHANGE_MODE_RATIO, BOTTOM_CHANGE_MODE_RATIO);
每一个控件都要调用这个宏，参数调试调试看看参数说明
如果是combo控件，改变大小后会下拉框下拉不了，则可以BOTTOM设为0即解决此问题
AUTO_SET_CONTROL_POS(IDC_COMBO1, LEFT_CHANGE_MODE_RATIO, RIGHT_CHANGE_MODE_RATIO, TOP_CHANGE_MODE_RATIO, BOTTOM_CHANGE_MODE_FIXED_HEIGHT);
