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

// CtrlId           : 控件ID
// LeftChangeMode   : 0:与窗口客户区左边的距离不变; 1:按比例变化; 2:保持控件宽度不变;
// RightChangeMode  : 0:与窗口客户区右边的距离不变; 1:按比例变化; 2:保持控件宽度不变;
// TopChangeMode    : 0:与窗口客户区上边的距离不变; 1:按比例变化; 2:保持控件高度不变;
// BottomChangeMode : 0:与窗口客户区下边的距离不变; 1:按比例变化; 2:保持控件高度不变;

增加对话框的WM_SIZE消息处理函数

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
