CV> So you don't destroy the window but simply hide it, right?

yes. if i understood Kazuhiro correctly, he was annoyed with the
window showing at his desktop. at least, i was :), that's why i wrote
it.

frankly, i don't know if ttyfier can help with the problems Kazuhiro
encountered. ttyfier calls CreateProcess() with separate new console,
and it it creates it with child's console window hidden. so, in case
of Kazuhiro, he can normally run everything either from service or from
normal interactive session -- he won't have unneeded console window
shown up on his desktop.

but my point is that ttyfier was designed for somewhat different
purposes, i.e. for running interactive native apps, and have its own
limitations. So, hiding annoying window from the desktop can be done
with simpler program.
