对话框

模态对话框的创建：

CMyModalDialog dlg;
dlg.DoModal();

非模态对话框的创建：

    //定义对话框指针
    CMyNoModalDialog *pDlg = new CMyNoModalDialog();
    //创建对话框
    pDlg->Create(IDD_NOMODAL_DIALOG, this);
    //显示对话框
    pDlg->ShowWindow(SW_SHOW);

向导对话框实例(孙鑫vc Lesson8)：

1、新建单文档解决方案：Prop

2、新建三个Dialog资源：IDD_PROP1  IDD_PROP2 IDD_PROP3 

3、分别添加基于CPropertyPage类CPop1 CPop2 CPop3

4、添加基于CPropertySheet类CPropSheet

5、在CPropSheet框架中定义3个属性页:

PropSheet.h

public:
    CProp1 m_prop1;
    CProp2 m_prop2;
    CProp3 m_prop3;

6、在CPropSheet构造函数中添加3个属性页

PropSheet.cpp

CPropSheet::CPropSheet(UINT nIDCaption, CWnd* pParentWnd, UINT iSelectPage)
    :CPropertySheet(nIDCaption, pParentWnd, iSelectPage)
{
    AddPage(&m_prop1);
    AddPage(&m_prop2);
    AddPage(&m_prop3);
}

CPropSheet::CPropSheet(LPCTSTR pszCaption, CWnd* pParentWnd, UINT iSelectPage)
    :CPropertySheet(pszCaption, pParentWnd, iSelectPage)
{
    AddPage(&m_prop1);
    AddPage(&m_prop2);
    AddPage(&m_prop3);
}

7、在菜单中新建菜单项并添加事件处理函数

8、为属性页添加OnSetActive重载函数
