Getting the text of the input field from the MFC modal dialog after closing it

From the MFC modal dialog, I want to extract text from the edit window after closing the dialog. I tried to do this:

CPreparationDlg Dlg;
CString m_str;

m_pMainWnd = &Dlg;
Dlg.DoModal();
CWnd *pMyDialog=AfxGetMainWnd();
CWnd *pWnd=pMyDialog->GetDlgItem(IDC_EDIT1);
pWnd->SetWindowText("huha max");
return TRUE;

This does not work.
