Cannot send data with QTcpSocket

[stef13013]

Hi,

With Qt 4.8 under win32, I'm trying to send data to a tcp server

QTcpSocket sck;
 
sck.connectToHost(myip, 7800);
 
if (sck.waitForConnected(8000)==false)
  return -1;

QTcpSocket sck;

sck.connectToHost(myip, 7800);

if (sck.waitForConnected(8000)==false)
  return -1;

To copy to clipboard, switch view to plain text mode 

Connection works pretty well (I see it on the server)
But now

ret = sck.write("test data sending");

ret = sck.write("test data sending");

To copy to clipboard, switch view to plain text mode 

ret returned 17, cool...

But on server side, I received... nothing !?

(If I do the same thing in "pure" C socket, it works !?)

What am I doing wrong ?

Thanks for you help...
