Problems with TCP Raw Data

[borisbn]

1. change in >> header; to

in.readRawData( &header, sizeof( header ) );

in.readRawData( &header, sizeof( header ) );

To copy to clipboard, switch view to plain text mode 

to avoid read header as text
2. after in.readRawData( data, header ); tcpClient->bytesAvailable() seems to be not equal to header
try

QByteArray b( data, header )

QByteArray b( data, header )

To copy to clipboard, switch view to plain text mode 

3. I think it would be better to use QIODevice's peek function to retrieve header, then look if it greater, then tcpClient->bytesAvailable(), and ( if it is ) go further
