不用属性页方法实现上一步，下一步，对话框功能

1. 新建VS2010 MFC dlg工程 Test, 会自动生成 Test.cpp TestDlg.cpp

2. 在资源管理器里新建对话框 Dlg2, 为其添加类Dlg2

3. 在StdAfx.h添加

[cpp]

const int ID_END_DLG_PRE = 100; //打开起始对话框
const int ID_END_DLG_NEXT = 101; //信号源对话框

3. 在TestDlg对话框按钮添加下一步按钮, 添加代码

[cpp]
EndModalLoop(ID_END_DLG_NEXT);

4. 在Dlg2添加 "上一步"按钮, 添加代码

[cpp]
EndModalLoop(ID_END_DLG_PRE);

5. 在Test.cpp的 BOOL CTestApp::InitInstance() 添加

[cpp]
SetRegistryKey(_T("Local AppWizard-Generated Applications"));

//下面是添加的
    CTestDlg dlg1;
    CDlg2 dlg2;
    CDialogEx *dlg = &dlg1;
    tagMSG msg;

    m_pMainWnd = &dlg1;
    bool end_loop = false;

    while ( !end_loop )
    {

        INT_PTR nResponse = dlg->DoModal();

        //dlg 关闭后, 会发诸如 WM_QUIT的消息
        //用PeekMsg可以拦截此消息, 防止程序退出
        PeekMessage(&msg, NULL, 0, 0, PM_REMOVE);
        switch ( nResponse )
        {
        case IDOK:
        case IDCANCEL:
            end_loop = true;
            break;
        case ID_END_DLG_PRE:
            m_pMainWnd = &dlg1;
            dlg = &dlg1;
            break;
        case ID_END_DLG_NEXT:
            m_pMainWnd = &dlg2;
            dlg = &dlg2;
            break;
        default:
            end_loop = true;
            break;
        }
    }

//上面是添加的
    // Delete the shell manager created above.
    if (pShellManager != NULL)
    {
        delete pShellManager;
    }

原理大概就是开下一个对话框要先关闭当前对话框,

关闭对话框时若直接调用 EndDialog, 只能调用1次, 下一次 domodal就返回-1了
