Revolution 3.5
While doing an upload on the web server, I cannot get the progress bar to update (the screen is frozen...and updated regularly only at the very end).
On the main stack I have a

Code: Select all

put ThePageContent into URL ("file:" & PagePath)
libURLSetStatusCallback "myProgress",the long ID of scrollbar "ScrollbarTC" of stack "attesa"

on the scrollbar script I have a

Code: Select all

on  myProgress theURL,theStatus
   lock screen
   put theStatus into fld "ConnessioneFld" of stack "Attesa"
   put  the thumbPosition of scrollbar "ScrollbarTC"  of stack "attesa" into conteggio
   add 1 to conteggio
   set the thumbPosition of scrollbar "ScrollbarTC"  of stack "attesa"  to conteggio
   unlock screen
end myProgress

I tried with Screen Debug off, with a compiled application, and replacing the

Code: Select all

put theStatus into fld "ConnessioneFld" of stack "Attesa"

with

Code: Select all

put theStatus & return after msg

In this last case the msg is filled only at the and of the operation
No result without the lock unlock screen...
Any clue ?
Thanks

Any help ?
I've noticed that on OSX even a

Code: Select all

repeat with i = 1 to 10
myprogress
end repeat

does not update the scrollbar, but it does on windows (XP)
Is this a bug ?

Tight loops may prevent the engine from redrawing the screen. You can insert a wait statement in your loop and this will ensure redraw.

Code: Select all

repeat with i = 1 to 10 
  myprogress
  wait 0 milliseconds
end repeat

Have you got it working yet? If not, what is grabbing your file one the other side? If it's a php-enabled web server it is a known problem that php didn't return any status until the download is finished. I think some support was added in version 5.2 though but I haven't tried it.
If it's not php I still think your problem might be that the server is not returning any upload status.

My web server does not have 5.2 yet, and they are not planning on upgrading yet.
I partially solved my problem because I am sending several small file, not a single big one. That is doing some "send" at the end of each upload, when the script was resuming and upgrading the bar at each upload
If I had to do a single big one, no, I could not solve it...

My web server is a Linux Red Hat. Does it matter ?

I don't think that your linux version matters. I think it's your PHP version. If you also can run Perl on your server there is a working codebase here
