Start a download that takes some time to complete:

Wolfram Language code: progress = 0; downloadComplete = False; Row[{"Progress: ", ProgressIndicator[Dynamic[progress]]}] handleEvent[_, "progress", {bytesReceived_, bytesTotal_, ___}] := ( progress = bytesReceived / bytesTotal;) handleEvent[_, "data", data_] := (responseData = data; MessageDialog["Download complete."]) downloadTask = URLFetchAsynchronous["http://exampledata.wolfram.com/20mb.dat", handleEvent, Progress -> True]

Stop progress updates:

Wolfram Language code: StopAsynchronousTask[downloadTask]

Resume progress updates:

Wolfram Language code: StartAsynchronousTask[downloadTask]
Wolfram Language code: AsynchronousTasks[]
