how to transfer large files using QSocket

[wysota]

Could you provide any details on what you have already tried to achieve the goal? I believe there are examples bundled with Qt that describe how to use QSocket.

hi,
this is the code for upload a file from client side to server side

/*! Used to upload a file */
void ACMClient::fileUpload(QString &a_fileToSend)
{
	QFile l_file(a_fileToSend);
 
	if(l_file.exists())
	{
		if ( l_file.open(IO_ReadOnly ) ) 
		{
			QByteArray l_byteArray = l_file.readAll();
 
			l_byteArray = qCompress(l_byteArray);
			QString l_string(l_byteArray);
			QString l_byteArraySize;
			l_byteArraySize.setNum(l_byteArray.size(),10);
 
			QMessageBox::information(this, "FTP", l_byteArraySize);
										               m_socket->writeBlock( l_byteArray,l_byteArray.size() );
		}
	}
}

/*! Used to upload a file */
void ACMClient::fileUpload(QString &a_fileToSend)
{
	QFile l_file(a_fileToSend);

	if(l_file.exists())
	{
		if ( l_file.open(IO_ReadOnly ) ) 
		{
			QByteArray l_byteArray = l_file.readAll();

			l_byteArray = qCompress(l_byteArray);
			QString l_string(l_byteArray);
			QString l_byteArraySize;
			l_byteArraySize.setNum(l_byteArray.size(),10);

			QMessageBox::information(this, "FTP", l_byteArraySize);
										               m_socket->writeBlock( l_byteArray,l_byteArray.size() );
		}
	}
}

How do you read the data on the server? Are you aware that the data might arrive in several chunks that you have to merge?
