The put() method returns straight away and the data to be put is added to a queue and uploaded in the background. Your selectFile() method returns straight away therefore your upload_file object goes out of scope before it can be sent. Simply changing upload_file to self.upload_file will solve your problem.</div></div><div><br></div><div>Hope this helps ;o)</div><div>Rob</div><div><br></div><div><br></div><span id="OLK_SRC_BODY_SECTION"><div style="font-family:Calibri; font-size:11pt; text-align:left; color:black; BORDER-BOTTOM: medium none; BORDER-LEFT: medium none; PADDING-BOTTOM: 0in; PADDING-LEFT: 0in; PADDING-RIGHT: 0in; BORDER-TOP: #b5c4df 1pt solid; BORDER-RIGHT: medium none; PADDING-TOP: 3pt"><span style="font-weight:bold">From: </span> 不坏阿峰 <<a href="mailto:onlydebian@gmail.com">onlydebian@gmail.com</a>><br><span style="font-weight:bold">Date: </span> Tuesday, 1 July 2014 03:30<br><span style="font-weight:bold">To: </span> <<a href="mailto:pyqt@riverbankcomputing.com">pyqt@riverbankcomputing.com</a>><br><span style="font-weight:bold">Subject: </span> [PyQt] How to add ftp put function in PyQT network ftp demo<br></div><div><br></div><div dir="ltr"><span style="color: rgb(0, 0, 0); font-family: Arial, 'Liberation Sans', 'DejaVu Sans', sans-serif; font-size: 14px; line-height: 17.804800033569336px; ">I want to modify the pyqt network ftp demo to include an upload function, but I am failing.
