Why doesn't this code work?

In an ordinary MFC modal Dialog based application I'm doing this.
InitInstance()
{
CMyDlg dlg;
int nResponse = dlg.DoModal();
if(nResponse == ID_OK)
do_something;
nResponse = dlg.DoModal();
}
When I call DoModal for the second time, the dialog will not appear at all. Why is this?
Please help.
Thanks,
Shyam

Hi,

if you do not want the dialog to reappear after pressing OK do you handling in OnOK in the dialog and let not destroy it.

OR

{
CMyDlg *pMyDlg;

pMyDlg = new CMyDlg;

while (pMyDlg->DoModal() == ID_OK)
{
// DoSomething

delete pMyDlg;
pMyDlg = new CMyDlg;
}

delete pMyDlg;
}

Regards,

Bernd
