if(QDir::setCurrent(path))
qDebug()<<"path set";

qDebug()<<"Couldn't set path";
 QFile *file = new QFile(filename);
 file->open( QIODevice::ReadWrite );
 ftp.connectToHost("192.100.1.00");

To copy to clipboard, switch view to plain text mode

QFtp::put returns a command ID. You must save this ID and connect a slot to the QFtp::commandFinished signal. When you get that ID you can be sure that the upload has been completed and close the connection.

Your current code closes the connection immediately, there is no transfer performed.

Your current code closes the connection immediately, there is no transfer performed.

QFtp::close() only schedules a disconnection - it doesn't perform it immediately.

@sinha.ashish: What is the contents of "filename"?
