    MFC Question

    Okay.

    I have two Dialogs, lets call them IDD_DLG1 and IDD_DLG2.

    On IDD_DLG1 I have an array of CStrings(lets say 50). There is a CListBox control on IDD_DLG2. Why does this not work:


    IDD_DLG1 code:

    User clicks "View List of Names" button (the array of CStrings) on IDD_DLG1.

    Code:
    CDLG2 myDlg;
    
    myDlg.DoModal();
    
    for(int i = 0; i < 50; i++)
    {
        myDlg.ListBox.AddString(names[i]);
    }

    You call

    Code:
    myDlg.DoModal();
    and it does not return until the dialog ends.....therefore, by the time you run

    Code:
    for(int i = 0; i < 50; i++)
    {
        myDlg.ListBox.AddString(names[i]);
    }
    the dialog is gone.....therefore AddString will not operate...
