    How to set the parent dialog??

    Hi all,

    I’ve created a modeless dialog from my main dialog as follows:

    Code:
    m_pContainerDlg = new CDlgContainer(NULL, this);
    m_pContainerDlg->Create(CDlgContainer::IDD, GetDesktopWindow());
    m_pContainerDlg ->ShowWindow(SW_SHOW);
    This container dialog creates a child dialog which I show inside the container

    Code:
    BOOL CDlgContainer::OnInitDialog()
    {
        // Create the child dialog and show it 
        m_pChildDlg = new CChildDlg(this);
        m_pChildDlg->Create(IDD_DIRECTORY_DIALOG, this);
    
        return FALSE;
    }
    From my child dialog I then create a modal dialog when a user clicks on a button

    Code:
    CChildDlg:: CChildDlg (CWnd* pParent /*=NULL*/)  : 
    	m_pParent((CDlgContainer*)pParent),
    {
    }
    
    void CChildDlg::OnBnClickedBtn()
    {
        CMyDlg MyDlg;
        INT_PTR iResult = MyDlg.DoModal(pParent);
    }
    My problem is that the CMyDlg is modal but to the main dialog and not to the container or the child dialog.

    Can anyone please advise??

    Does this code compile?
    AFAIK CDialog::DoModal has no parameters at all:

    "My problem is that the CMyDlg is modal but to the main dialog and not to the container or the child dialog."

    I'm not even sure what that means. Modality isn't constrained or affected by a parent/child relationship.

    Pointer to parent must be passed via constructor parameter, and your CMyDlg must have the corresponding constructor.

    Code:
    
    class CMyDlg: public CDialog
    {
    . . .
        CMyDlg(CWnd* pParent = NULL): CDialog(IDD, pParent) {. . .}
    };
    
    
    CChildDlg:: CChildDlg (CWnd* pParent /*=NULL*/)  : 
        m_pParent((CDlgContainer*)pParent),
    {
    }
    
    void CChildDlg::OnBnClickedBtn()
    {
        CMyDlg MyDlg(this);
        INT_PTR iResult = MyDlg.DoModal();
    }
    Best regards,
    Igor
