1、让对话框从CdialogResize类继承过来：

class CMainDlg : public CDialogImpl<CMainDlg>,

public CDoubleBufferImpl<CMainDlg>,

public CDialogResize<CMainDlg>

2、添加消息路由

BEGIN_MSG_MAP(CMainDlg)

CHAIN_MSG_MAP(CDialogResize<CMainDlg>)

CHAIN_MSG_MAP(CDoubleBufferImpl<CMainDlg>)

MESSAGE_HANDLER(WM_INITDIALOG, OnInitDialog)

COMMAND_ID_HANDLER(IDCANCEL, OnCancel)

END_MSG_MAP()

3、添加消息映射

BEGIN_DLGRESIZE_MAP(CMainDlg)

DLGRESIZE_CONTROL(IDC_STATIC_INPUT,  DLSZ_SIZE_X)

DLGRESIZE_CONTROL(IDC_STATIC_SEARCH, DLSZ_SIZE_X | DLSZ_SIZE_Y)

END_DLGRESIZE_MAP()

4、在OnInitDialog()中调用DlgResize_Init();

当对话框存在GroupBox的话，需要将GroupBox设置为透明背影

Transparent:true

测试代码：

MainDlg.h

// MainDlg.h : interface of the CMainDlg class///#pragma once#include 
    
     class CMainDlg : public CDialogImpl
     
      ,	public CDoubleBufferImpl
      
       ,	public CDialogResize
       
        {public:	enum { IDD = IDD_MAINDLG };	BEGIN_MSG_MAP(CMainDlg)		CHAIN_MSG_MAP(CDialogResize
        
         )		CHAIN_MSG_MAP(CDoubleBufferImpl
         
          ) MESSAGE_HANDLER(WM_INITDIALOG, OnInitDialog) COMMAND_ID_HANDLER(IDCANCEL, OnCancel) END_MSG_MAP() BEGIN_DLGRESIZE_MAP(CMainDlg) DLGRESIZE_CONTROL(IDC_STATIC_INPUT, DLSZ_SIZE_X) DLGRESIZE_CONTROL(IDC_STATIC_SEARCH, DLSZ_SIZE_X | DLSZ_SIZE_Y) END_DLGRESIZE_MAP()// Handler prototypes (uncomment arguments if needed):// LRESULT MessageHandler(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& /*bHandled*/)// LRESULT CommandHandler(WORD /*wNotifyCode*/, WORD /*wID*/, HWND /*hWndCtl*/, BOOL& /*bHandled*/)// LRESULT NotifyHandler(int /*idCtrl*/, LPNMHDR /*pnmh*/, BOOL& /*bHandled*/) LRESULT OnInitDialog(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& /*bHandled*/); LRESULT OnCancel(WORD /*wNotifyCode*/, WORD wID, HWND /*hWndCtl*/, BOOL& /*bHandled*/); void DoPaint(CDCHandle dc);private: Gdiplus::GdiplusStartupInput gGdiInput; ULONG token;};
         
        
       
      
     
    

MainDlg.cpp
