     First of all, I must announce that the main ideas of this paper are from Programming Microsoft Visual C++ Fifth Edition.

 

 

In order to demostrate the modeless dialog. Here I take the following steps:

 

1   Setup a single document MFC project.

 

2   Add a dialog (here we must make the dialog visiable), Here I do nothing to the dialog.   The Create a new Dialog class for this dialog only has a pointer to its parent and also a User message to communicate with its parent. See the following segment for more information:

 

 

 

 

 

3 In the View class header, I add a CModelessDlg member, its forward declaration and the initialization of the class.

 

 

// forward declaration
class CModelessDlg;

 

 

private:
    CModelessDlg* m_pDlg;

 

 

CmodelessView::CmodelessView()
{
    // TODO: add construction code here
    m_pDlg=new CModelessDlg(this);
}

CmodelessView::~CmodelessView()
{
    if(m_pDlg)
        delete m_pDlg;
}

 

4 Add a menu item named "Find" to the edit menu. and map its on command like this.

 

 

 

5 The above operation we can implement a modeless dialog now. but i also forward the dialog message to its parent

    for more processing, The ToParent message.
