problem with QTcpSocket

[SuperSonik]

Hi,
I'm not sure. I read a Qt book, and there I read I have to write the lenght of my message first
in my tcp package as a qint64.
I took the code out of the book and chance a few things.
In real I only want to send the string as I write it in the QString. -> exactly this String
I thought to write the lenght before the message is something I have to do because of tcp.

Take a look at the docs, you'll notice the write() method that takes a byte array as its argument (it's probably defined in QIODevice class).

Ok,
I have found my problem. I think my programm is working for a while.
The error message was wrong. If I call tcpsocket.errorString() and there is no error the funktion returns "Unknown error".
Now it's working. Thank you to all.
