I don't think it is possible (or reasonable). DoModal returns an INT_PTR, which is usually used to know what the user did to exit the dialog (press OK, Cancel, there was an error...). The way to do it is have public members or functions which the dialog set and the caller of the dialog can access to know the values. Like so:

CMyDialog dlg;

if(dlg.DoModal()==IDOK)
{
    CString str1 = dlg.m_String1;
    CString str2 = dlg.GetString2();
}

It's the way you would use CFileDialog, for example.
