This has already been tried. I want the second dialog to be hidden when
the first one is displayed on clicking BACK..
this is what we have in OnNext
void CPrintWizardDlg::OnNext()
{
    AfxGetMainWnd()->ShowWindow(SW_HIDE);
    UpdateData(TRUE);

    CDecisionDialog decDlg;
    decDlg.DoModal();
}
this is what we have in OnBack
void CDecisionDialog::OnBack()
{

    AfxGetApp()->HideApplication();
    CPrintWizardDlg prtWizDlg;
    prtWizDlg.DoModal();
}

This creates a new instance of the first dialog .But i need the dialog
to be displayed with its previous contents i.e the count of images

please suggest what could be done ????

savithanaren:

Obviously, you just want to re-show the original firdt dialog, not
create a new one.

Have you really tried exactly what AliR suggested? And the in second dialog

void CDecisionDialog::OnBack()
{
EndDialog(IDOK);
}

Or do you want the second dialog to preserve state also? In that case
maybe it should be modeless.

As AliR suggested, using CPropertySheet/CPropertyPage in Wizard mode
might be a better idea.
