My Dialog close itself

mfc · #1 14-Sep-2006, 15:53

Hi, I'm having the following problem:
I’ve build a dialog application. My main class creates the first dialog - login dialog.
Now, for each type of user, the application creates a unique dialog, for example:

CPP / C++ / C Code:

void CBankDlg::OnButtonLogin() {
……
	UpdateData(true);

	pIter_user_vector iter_begin = p_app->p_users_vector.begin();
	pIter_user_vector iter_end   = p_app->p_users_vector.end();

	
	for (; iter_begin != iter_end; ++iter_begin)
	{
		if ((*iter_begin)->GetUserName() == m_user_name &&
		            (*iter_begin)->GetUserPassword() == m_user_password)
		{
                  	CDialog *p_user_dialog = Factory::CreateUserDialog(*iter_begin);
			rst = p_user_dialog->DoModal();
			(*iter_begin)->DestroyUserDialog(p_user_dialog);
			break;
		}
	}
	m_user_name.Empty();
	m_user_password.Empty();
	UpdateData(false);		
	m_login_control.EnableWindow(false);
}

CPP / C++ / C Code:

CDialog* Banker::CreateUserDialog()
{
	return new BankerDialog();
}

Each of these secondary dialogs has a “Back” button that supposes to close itself and reopen the login dialog once again. The problem is that sometimes after clicking on the "Back" button on the secondary dialogs and inserting a new user in the login dialog, the login dialog just close itself and doesn't continue to create the next dialog.
How can I overcome this behavior?
The login dialog doesn’t suppose to close until the user will hit the “Close button”.

Please help
