[omprakash]

dear friends, i have written two applications.
One is client application using QTcpSocket class.
Another is server application using QTcpServer class.

So why don't you do it the same way?

[omprakash]

i have used code like below for sending the string.

QByteArray block;
QDataStream out( &block, QIODevice::WriteOnly );
out.setVersion(QDataStream::Qt_4_0);
out<<"SomeString";
out.device()->seek(0);
out << (quint16)(block.size() - sizeof(quint16));
tcpsocket->write(block);

Now just hint me what should i insert into code for my file transfer...
bye

1. Read a chunk of file to a byte array,
2. Write the contents of the byte array to the socket,
3. Repeat until you reach the end of the file.

Come on, the task is really simple - it fits more for the newbie forum and not the programming forum.
