Why use SendMessage() at all?
Since you expect Edita main windows to be top level and of some window class you
may invent for this purpose (don't you?), use FindWindow(lpEditaClassName,NULL).
No need to deal with window text, which ANSI/Unicode issues might make more
confuse. And the process being dead is not a problem, since it is not queried at
all.
