accessing Class members

Hi,

I attached a project about my question. It is created by a class which i found in CodeGuru, a TabControl. From the main dialog file(MyTabExampleDlg.cpp) i want to get the handle of the button but i couldnt.

In fact i can get the handle in "CTabOne" class and store it in same class, then storing it in class as a member.

Code:

---

class CTabOne : public CDialog
{
// Construction
public:
        CTabOne(CWnd* pParent = NULL);  // standard constructor
[...]
          HWND        hbutton;
[...]
};

/////////////////////////////////////////////////////////////////////////////
// CTab1 message handlers

BOOL CTabOne::OnInitDialog()
{
        CDialog::OnInitDialog();
       
        // TODO: Add extra initialization here

        hbutton = ::GetDlgItem(m_hWnd, IDC_BUTTON1);

        return TRUE;  // return TRUE unless you set the focus to a control
                      // EXCEPTION: OCX Property Pages should return FALSE
}

---

Then in the main dialog (MyTabExampleDlg.cpp),

Code:

---

BOOL CMyTabExampleDlg::OnInitDialog()
{
        CDialog::OnInitDialog();
[...]       
        CTabOne tab1;
        HWND buttonHandTest = tab1.hbutton;                        //        << Here!
[...]
        return TRUE;  // return TRUE  unless you set the focus to a control
}

---

The place which i show in second peace of code, this is not returning the handle. I know i am doing wrong, obviously, but what is the correct one?


Thanks

Code:

---

BOOL CMyTabExampleDlg::OnInitDialog()
{
        CDialog::OnInitDialog();
[...]       
        CTabOne tab1;
        HWND buttonHandTest = tab1.hbutton;                        //        << Here!
[...]
        return TRUE;  // return TRUE  unless you set the focus to a control
}

---

Just a guess:

Code:

---

BOOL CMyTabExampleDlg::OnInitDialog()
{
[...]       
        CTabOne tab1;

        tab1.OnInitDialog();
        HWND buttonHandTest = tab1.hbutton;                        //        << Here!
[...]
        return TRUE;  // return TRUE  unless you set the focus to a control
}

Thank you swoopy,

error C2248: 'OnInitDialog' : cannot access protected member declared in class 'CTabOne'

this is the error i get. I suppose maybe can use accessors, not sure but, in fact i am not sure how to do this.

Any idea? How can be access to a control over a child dialog from main dialog?

I reall will be a crazy, couldnt find any example do this, please help, or give me an example.

Thanks

hmm, like boomerang i reply to myself. I forgot to write to forum my solve. Maybe somebody needs,:p

1. in .cpp of child dialog;

CWnd *CWndTab1; // global

for a control over, in WM_INITDIALOG,

CWndTab1 = m_edit1.GetParent();


2. in main .cpp (where will be use),

extern CWnd *CWndTab1; // global

and when using,

CWndTab1->IsDlgButtonChecked(...);

and also for other controls over target child dialog.

If i didnt forget anything, this was my solution.
