If dialog is modal:

Close the parent window after returning from DoModal;

You don't return from DoModal until the dialog is closed.

If dialog is not modal:

When you initialize the dialog, send a pointer of the parent to the dialog.

Close the parent using the pointer, where you capture the dialog close event.
