Problem with Modal Dialog

I have multiple dialog applications. One dialog opens the another dialog. I am opening a Dialog say Dialog 2 from Dialog1 by calling DoModal() method. I am opening an another dialog say Dialog3 from Dialog2 using the same method DoModal(). Even after opening Dialog3 i can access Dialog2 just like Dialog3 is a modeless dialog. But i want Dialog3 to be Modal so that as long as Dialog3 is open user can't access dialog2.

Please HELP

Do you mean multiple applications, or one application with multiple dialogs?

one application multiple dialogs. sorry for confusion

Is this possible to have modal dialog over another modal dialog in one application. That's what i am asking. If yes, so what i am doing wrong?

Please HELP!!!

I tested what you said. I have three dlg.
in a button of dlg1, I make dlg2 DoModel, code link:
void CDlgA::OnButton1()
{
// TODO: Add your control notification handler code here
CDlgB dlg_b;
dlg_b.DoModal();
}

and in a button of dlg2, I make dlg3 DoModel,

and after opening Dialog3 , I can not access Dialog2

so I wonder how you create your dialog?

I am not sure why its not working. Even i open a CColorDialog which supposed to be a modal dialog from mfc. But i still able to access the dialog which opens CColorDialog. I am confused. Supposed to be the simplest thing, but still it is very complex.

I need help. There has to be wrong with some my dialog properties which is making it behave like that.

you'd better put your code about how you open your dialog and what property it have
