How can I start programming this program ?

Hi everyone,
I was asked to write a program with MFC. It's about Linked List .
This is how I would start :




When the user press button EXIT, the program should terminate ( How can I do that ? ).

When the user press button Singly linked list, the program should open another Dialog ( #2 ) and the others the same ( How can I do that ? ).

 

To be more clear, What Should I Write In This Function :

PHP:

void CTetDlg::OnButton1() 
{
    // TODO: Add your control notification handler code here
    
}

While the Button1 points to EXIT button ?

 

OK, I figure it out :

PHP:

 void CTetDlg::OnButton1()
{
    exit(1);
    
} 

 

Note: the program I'm creating is based on Dialogs only.

Now, I want to fox in creating a SLL Dialog , which should appears when I press the Singly linked list button on the First Dialog.

This is the function for button 3 :

PHP:

void CTetDlg::OnButton3() 
{
    // TODO: Add your control notification handler code here
    SLL newSll;
    
}

That does not work, even when I created a SLL class, this the header file for SLL class:

PHP:

#if !defined(AFX_SLL_H__4C827A8A_AB05_4879_8765_3161DEFA7142__INCLUDED_)
#define AFX_SLL_H__4C827A8A_AB05_4879_8765_3161DEFA7142__INCLUDED_

#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000
// SLL.h : header file
//

/////////////////////////////////////////////////////////////////////////////
// SLL dialog

class SLL : public CDialog
{
// Construction
public:
    SLL(CWnd* pParent = NULL);   // standard constructor

// Dialog Data
    //{{AFX_DATA(SLL)
    enum { IDD = IDD_PROPPAGE_MEDIUM };
        // NOTE: the ClassWizard will add data members here
    //}}AFX_DATA


// Overrides
    // ClassWizard generated virtual function overrides
    //{{AFX_VIRTUAL(SLL)
    protected:
    virtual void DoDataExchange(CDataExchange* pDX);    // DDX/DDV support
    //}}AFX_VIRTUAL

// Implementation
protected:

    // Generated message map functions
    //{{AFX_MSG(SLL)
    afx_msg void OnButton7();
    afx_msg void OnButton1();
    afx_msg void OnButton2();
    afx_msg void OnButton3();
    afx_msg void OnButton4();
    //}}AFX_MSG
    DECLARE_MESSAGE_MAP()
};

//{{AFX_INSERT_LOCATION}}
// Microsoft Visual C++ will insert additional declarations immediately before the previous line.

#endif // !defined(AFX_SLL_H__4C827A8A_AB05_4879_8765_3161DEFA7142__INCLUDED_)

So, what should I do ?

 

Where are you people ? I need help really ..

Here you are what I have done by now ( Just designing, I don not know how to write commands to open or close or to call ...etc ):









Now, I want the IDD_SLL_DIALOG opens when I press SLL button & create a new SLL object ( I have the code for it but I don not know where should I put it ).

And, when I press EXIT button ( on IDD_SLL_DIALOG ) I want the program return to IDD_TET_DIALOG not ending the whole program.

 

Thank you Mr.Shabbir for the reply

I do not know how to do this :

could you please help me by using the previous information in reply #5 ?

 

PHP:

You need to add the code in the button handler which is generated with the IDE as I mentioned above.

Could you please tell me what code should I add ?
I tried this :

PHP:

SLL dlg;
dlg.DoModal();
if ( dlg.DoModal() == IDCOK )
        AfxMessageBox(_T("Its OK!"));

and the compiler didn't show me any error, although, the program crashed when I pressed SLL button !
