No, Stéphane meant progressionbar() not waitbar().
Something like:
winId=progressionbar('Reading Excel files');
xlread(...)
close(winId);
Should do what you need.

Hi
That is what I have essentially done , just update the waitbar through
sections of the code as read in multiple data sets.
To have the ability to have a user thread would be great or a periodic
timer that has a call back mechanism.
I really don’t care about the exact progress of the waitbar , all I want
is to give the user feedback that something is happening as the excel
reads are slow because of the size of the data .
Cheers
Greg

Hello,
You have the progession bar, i.e.
progressionbar('Please wait while loading data');
which is incorrectly named as it cannot show any progression (unlike
waitbar()) but only a kind of bar which oscillates, showing that
something is happening. This one will keep oscillating in an
asynchronous way (in the background) until you delete it.
However, even if Scilab would be able to launch threads at the user
level, updating a bar showing progression would need to be hardcoded in
xls_read, because you have to know the current position you are reading
w.r.t. the overall size ot the data stream.
The only case where something could be done is if your data is organized
in many sheets within the xls file. In that case you could iterate on
sheets and update a waitbar().

Hi
Is there a periodic timer like the Matlab timer function ? The
parallel run function does not seem to exist in the 2023.1.0 release
, as I thought I may be able to use that instead.
I am reading a large excel spreadsheet and it would be good to
implement a progress bar . So, a periodic timer that runs in the
background could be used to check a flag finish flag . If the finish
flag is false increment the progress and fire the timer off again.
Kind Regards
Greg
