Question

Okay basically I have an MFC application with lots of dialogs that need to be cycled through. Basically when you click one button to go to another dialog, I want the previous dialog to close. Right now the dialogs are just displayed over the top of each other. How do I get the dialog to close once the new dialog has opened? Here is some example code:

void CMachine2Dlg::OnBnClickedNewmc()
{
    NameDlg Dlg;
    Dlg.DoModal()       

    }

What you can do is hide the parent dialog when you DoModal() the new dialog and destroy it after the new dialog ends. I have not tested the ShowWindow() below but you get the idea, if it doesn’t hide the dialog look for another similar function.

void CMachine2Dlg::OnBnClickedNewmc()
{
   ShowWindow( SW_HIDE);

   NameDlg Dlg;
   Dlg.DoModal();

   EndDialog( 0 );

}
