假設(shè)創(chuàng)建的對話框的類名是CMyDlg，具體過程如下：

步驟一：把easysize.h拷貝到CMyDlg項(xiàng)目文件夾中，同時(shí)在CMyDlg的.h文件和.cpp文件中加入#include "easysize.h"；

步驟二：在CMyDlg類的h文件中，加入DECLARE_EASYSIZE，注意結(jié)尾處不要加“；”。

class CMyDlg : public CDialog

{

?????? DECLARE_EASYSIZE

// Construction

…

}

步驟三：在CMyDlg類的OnInitDialog()函數(shù)的結(jié)尾處加入INIT_EASYSIZE, 注意此處結(jié)尾處要加“；”。

BOOL CMyDlg::OnInitDialog()

{???? …

// TODO: Add extra initialization here

?????? INIT_EASYSIZE;

?????? return TRUE;? // return TRUE? unless you set the focus to a control

}

?

步驟四：增加WM_SIZE消息響應(yīng)函數(shù)OnSize()，在函數(shù)中加入U(xiǎn)PDATE_EASYSIZE，注意此處結(jié)尾處要加“；”。

void CMyDlg::OnSize(UINT nType, int cx, int cy)

{

?????? CDialog::OnSize(nType, cx, cy);

?????? // TODO: Add your message handler code here

????? UPDATE_EASYSIZE;

}

步驟五：在CMyDlg的cpp文件中添加EASYSIZE 的宏映射

BEGIN_EASYSIZE_MAP(CMyDlg)

EASYSIZE(control,left,top,right,bottom,options)

END_EASYSIZE_MAP

注意：如果沒有添加EASYSIZE 的宏映射就開始編譯的話，會出現(xiàn)鏈接錯(cuò)誤！

這里需要解釋的是宏EASYSIZE()的用法，其原型如下：

EASYSIZE(control,left,top,right,bottom,options)

該宏表示對ID值為control的控件實(shí)施縮放效果，縮放后的上下左右位置由control,left,top,right,bottom來確定，大小由option確定。

其中：control為對話框中的控件ID值，left,top,right,bottom四個(gè)參數(shù)為控件位置的坐標(biāo)，其值可以選擇ES_BOARD,ES_KEEPSIZE, 控件ID值三者之一。Options可以為ES_HCENTER, ES_VCENTER的結(jié)合，options可置0。

ES_BOARD表示控件與對話框邊界（以下簡稱邊界）的距離；

ES_KEEPSIZE表示控件水平/垂直方向上尺寸保持不變；

控件ID值表示當(dāng)前控件與指定控件之間的距離；

ES_HCENTER表示縮放后控件在指定位置內(nèi)水平居中；

ES_VCENTER表示縮放后控件在指定位置內(nèi)垂直居中；

?

例如：

EASYSIZE(IDOK,ES_BORDER,ES_BORDER,ES_BORDER,ES_BORDER,0)

表示縮放后，值為IDOK的控件，距離邊界上下左右位置保持不變，水平和垂直方向尺寸拉伸；

EASYSIZE(IDOK,ES_BORDER,ES_BORDER,ES_BORDER,ES_BORDER,ES_HCENTER)

表示縮放后，值為IDOK的控件，距離邊界上下位置保持不變，垂直方向尺寸拉伸，水平居中；

EASYSIZE(IDOK,ES_BORDER,ES_BORDER,ES_BORDER,ES_BORDER,ES_HCENTER| ES_HCENTER)

表示縮放后，值為IDOK的控件，在對話框內(nèi)垂直居中，水平居中；

EASYSIZE(IDOK,ES_BORDER,ES_KEEPSIZE,ES_KEEPSIZE,ES_BORDER,0)

表示縮放后，值為IDOK的控件，距離邊界左、下方位置保持不變，同時(shí)保持控件尺寸；

EASYSIZE(IDOK,ES_BORDER,ES_KEEPSIZE, ES_BORDER,ES_BORDER,0)

表示縮放后，值為IDOK的控件，距離邊界左、右、下方位置保持不變，水平方向尺寸拉伸，垂直方向尺寸不變；

?EASYSIZE(IDOK,ES_BORDER,ES_BORDER,IDCANCEL,ES_BORDER,0)

表示縮放后，值為IDOK的控件，距離邊界上下左位置保持不變，距離ID值為IDCANCEL的右方位置距離保持不變，水平和垂直方向尺寸拉伸；（當(dāng)使用指定控件作為定位參數(shù)時(shí)候，確保指定控件的EASYSIZE在該宏前面）
