I am a little confused on the full usage of the word "чтобы." I understand that it can be used as "in order to blah blah blah" but I'm somewhat cloudy when I see it in other places. I've heard it also means "so that" that but I can't figure it out. Any help on explaining it would be greatly appreciated. I'll put some ex. sentences I've seen it in and don't really understand. Thanks again in advance for any help.

Я хочу, чтобы она пришла.
Не может быть, чтобы он так поступил.
Чтобы она заболела!
Чтобы я его здесь больше не видел!

I have English translations to these sentences but can't really understand the use of the word in these cases.

i want her to come
it's impossible that he could act that way
To make her ill !
I don't want to see him here again.

sorry, but you`re not right. examples are ok. ?? is writed like this.
it's language specific - frequent usage of one word in different connotations.
