AfxGetMainWnd () call

Hi,

I`ve a CFormView in my SDI application as well as a dialog where the
user can change some settings to specific parts of the software. After
clicking on the "ok"-button I will create another dialog (CWaitDialog)
to verify all these settings the user has made.

I`m not sure if it is recommended to use the constructor to start this
dialog as well as the use of AfxGetMainWnd() (of course in the
mainthread). I`m not really sure in which situations it makes sense to
call such a global method.

CWaitDialog::CWaitDialog (BOOL pFlag, CString& pszCaption, CString&
pszText) : CDialog ()
{
    m_pFlag = pFlag;

    // Disable the main window and create the dialog.
    AfxGetMainWnd ()->EnableWindow (FALSE);
    Create (IDD_WAITDIALOG);

    // Initialize the dialog caption and the static text control.
    SetWindowText ((pszCaption.GetLength()) ? _T("Working") :
pszCaption);

    // Display the dialog.
    ShowWindow (SW_SHOW);
}

and here is my call of this dialog in the method OnWizardFinish()
which will be called if the user clicks the "ok" button to update his
settings.

void CWizardDialog::OnWizardFinish()
{
   BOOL bContinue = TRUE;
   BOOL stillWorking = TRUE;

   CString dialogtitle ("Please wait...");
   CString dialogtext ("Wait for me to do my stuff...");
   CWaitDialog dlg (bContinue, dialogtitle, dialogtext);

   while (stillWorking && bContinue)
   {
       //verify all data

       //add message to dialog if verifcation failed (to inform the
user)
   }

   //finished
   dlg.Close();
}

best regards
Hans
