1、不用说，首先隐射OnSize事件，然后在该事件中编写代码

2、这里要注意一个问题，那就是当窗口首次打开的时候，窗口上的空间事实上还没有创建，这个时候如果尝试移动控件位置将会出现错误，最常用的办法是使用GetSafeHwnd来判断控件窗口句柄是否存在，如果不存在就表示还没有创建，而且在窗口打开的时候只要判断一个就可以了

3、使用CRect 来处理控件的大小位置

 

我的代码处理：

// TODO: Add your message handler code here

 CRect rectClient; CRect rectEdit; int iButtonWidth,iButtonHeight;  //光判断信息窗口是否已经创建 if (IsWindow(GetDlgItem(IDC_EDIT_INFO)->GetSafeHwnd())) {    GetClientRect(&rectClient);   //设置 启动按钮  GetDlgItem(IDC_BUTTON_START)->GetClientRect(&rectEdit);  iButtonWidth = rectEdit.Width();  iButtonHeight = rectEdit.Height();  rectEdit.top = rectClient.bottom - 10 - rectEdit.Height();  rectEdit.bottom = rectClient.bottom - 10;  rectEdit.right = 10 + rectEdit.Width();  rectEdit.left = 10;  GetDlgItem(IDC_BUTTON_START)->MoveWindow(rectEdit,TRUE);  //设置 停止按钮  rectEdit.left = rectEdit.right + 10;  rectEdit.right = rectEdit.right + rectEdit.right;  GetDlgItem(IDC_BUTTON_STOP)->MoveWindow(rectEdit,TRUE);  //设置 清除日志  rectEdit.left = rectEdit.right + 10;  rectEdit.right = rectEdit.right + iButtonWidth;  GetDlgItem(IDC_BUTTON_CLEAR_INFO)->MoveWindow(rectEdit,TRUE);  //设置取消 右边重新计算  rectEdit.left = rectClient.right - 10 - iButtonWidth;  rectEdit.right = rectClient.right - 10;  GetDlgItem(IDCANCEL)->MoveWindow(rectEdit,TRUE);  //设置 设置按钮  rectEdit.left = rectClient.right - 10 - iButtonWidth - iButtonWidth - 50;  rectEdit.right = rectEdit.left + iButtonWidth;  GetDlgItem(IDC_BUTTON_GATEWAY_SETUP)->MoveWindow(rectEdit,TRUE);    //设置信息窗口  GetDlgItem(IDC_EDIT_INFO)->GetClientRect(&rectEdit);  rectEdit.left = 10;  rectEdit.right = rectClient.right - 10;  rectEdit.top = 10;  rectEdit.bottom = rectClient.bottom - 10 - iButtonHeight - 10;  GetDlgItem(IDC_EDIT_INFO)->MoveWindow(rectEdit,TRUE);    //设置发送测试信息  GetDlgItem(IDC_BUTTON_SEND_TEST)->GetClientRect(&rectEdit);  iButtonWidth = rectEdit.Width();  iButtonHeight = rectEdit.Height();  rectEdit.left = (rectClient.Width() - iButtonWidth ) / 2;  rectEdit.right = rectEdit.left + iButtonWidth;  rectEdit.bottom = rectClient.bottom - 10;  rectEdit.top = rectEdit.bottom - iButtonHeight;  GetDlgItem(IDC_BUTTON_SEND_TEST)->MoveWindow(rectEdit,TRUE); }
