[Qt-interest] Send a pdf thru QTcpSocket. Encoding problem?

[Josinei Silva]

Hi,

I'm trying to send a pdf created by my own Qt application printing to a file 
thru a QTcpSocket ( It's working with threads now. Thanks Thiago ). But the 
pdf that i received is not the same i sent.

This is the code used to send the file:

        QFile ReportFile( FileName );
        ReportFile.open( QIODevice::ReadOnly | QIODevice::Text );
        QString OutPut;
        QByteArray ReportArray = ReportFile.readAll();
        OutPut = ReportArray.toBase64();
        QByteArray Block;
        QDataStream Out( &Block, QIODevice::WriteOnly );
        Out.setVersion( QDataStream::Qt_4_0 );
        Out << (quint16)0;
        Out << OutPut;
        Out.device()->seek( 0 );
        Out << (quint16)( Block.size() - sizeof(quint16) );
        tcpSocket.write( Block );
        tcpSocket.waitForBytesWritten( TimeOut );

This is the code used to receive the file:

        QDataStream In( tcpSocket );
        In.setVersion( QDataStream::Qt_4_0 );
        quint16 BlockSize = 0;
        if ( tcpSocket->bytesAvailable() >= (int)sizeof(quint16) )
        {
          In >> BlockSize;
          if ( tcpSocket->bytesAvailable() >= BlockSize )
          {
            QString Report;
            In >> Report;
            QFile *File = FileOpen( FileName );
            QByteArray ReportArray = QByteArray::fromBase64( Report.toAscii() 
);
            File->write( ReportArray );
            File->close();
          }
        }

I saved the contens of "OutPut" and "Report" and they are the same. I think 
thar sending the encoded string it is not a problem. But i must be doing 
something wrong when encoding and decoding the pdf. I tried to send without 
encode but it doesn't look to work.

How can i encode and decode this file to send thru the QTcpSocket?

Thanks
