Has anyone used libURLSetStatusCallback successfully to monitor
the progress of downloads from a remote server? I am using it in
conjunction with libURLDownloadToFile and it seems to PARTLY work.
I use it to update a progress bar, and that is working okay. At
the same time I echo the status to a text field, but that part
seems to work once and then never change (it reports "requested"
then never changes, for example).
This seems odd. Presumably the updating of the progress bar uses
the same text you want to display in the text field. Can you show
us the script you are using?
OK, the download works, and the download progress is updated
correctly in the progress bar and the text field, but now when the
download finishes, the URLstatus seems to be "stuck" on the last
reported "loading" message. If I check the urlStatus for the just-
concluded download, I get:
loading,180902350,180902350
This effectively blocks all subsequent downloads. If I start another
the urlStatus reports "queued" for that download.
If I check the pendingMessages I get:
45839,1154622702.764941,ulTickleMe,button id 1037 of group id
1016 of card id 1002 of stack "/Applications/Revolution/Revolution
Enterprise/2.7.2-gm-1/Toolset/revlibrary.rev"
The only way to clear all of this is to quit Rev and relaunch.
Here is the scripting I am using to initiate the download (from an
FTP server):
libURLDownloadToFile tDLURL, (the DLfolder of this cd & "/" &
the titleToDL of me), "downloadComplete"
libURLSetStatusCallback DLprogress,the long id of me
That calls this handler:
on DLprogress pDLurl,pStatus
if pStatus contains "loading" then
put item -1 of pStatus into tBytestotal
put item 2 of pStatus into tBytesReceived
set the endvalue of scrollbar "dlProgress" to tBytestotal
set the thumbpos of scrollbar "dlProgress" to item 2 of pStatus
set the numberformat to "0.##"
put (tBytesReceived / 1000000) & " MB of " & (tBytestotal /
1000000) & " MB" into fld "dlMsg"
if tBytesReceived >= tBytestotal then
put "(DONE) " before line (the hilitedLine of fld "orderlist")
of fld "orderlist"
answer information "Download complete."
dowloadComplete
end if
else if pStatus is "contacted" then
put "Server contacted." into fld "dlMsg"
else if pStatus is "requested" then
put "Requesting file." into fld "dlMsg"
else if pStatus is "queued" then
put "Waiting for previous download to finish." into fld "dlMsg"
else if pStatus is "downloaded" then
put "Download complete." into fld "dlMsg"
downloadComplete #### I'm calling this to try to ensure it gets
called!
else if pStatus is "eror" then
put "Error during download." into fld "dlMsg"
answer error "The download encountered an error and could not
continue. Aborted."
downloadComplete
else if pStatus is "timeout" then
put "Server timed out." into fld "dlMsg"
answer error "The download server timed out. Download aborted."
downloadComplete
end if
end DLprogress
The downloadComplete handler is simple:
on downloadComplete
answer information "The file " & the titleToDL of btn "download" &
" has downloaded successfully."
hide group "dlStatusGrp"
end downloadComplete
Oddly enough, the first statement gets executed, but not the second.
I'm stumped. Am I just doing something wrong?
Any ideas?
