tcpstream and strings

[José Tavares]

I know this must be a very very simple question, but here it is:
I can send a string throw a tcpstream object using something like this
                tcpstream tcp;
                tcp << "Something like this" << endl;

but when I use the same scheme to read the message (something like tcp >> str, 
str is a string object) and then print it out (using cout << str) only the 
first word is read. How can I resolve this?

TIA,
