RE: Displaying a status bar
Should've known there's always a correct way. I was just adding the
increments without realizing the percentage bar numbers. Took your advice
and used setPercent() and removed the sleep(), and left buffering on. Works
great.
Thanks again,
David

Coincidence. It happens to go over 100 near the end of your loop, and thus
automatically disappears.

Iteration 1: increment(4), bar at 4%
Iteration 2: increment(8), bar at 12%
Iteration 3: increment(12), bar at 24%
Iteration 4: increment(16), bar at 40%
Iteration 5: increment(20), bar at 60%
Iteration 6: increment(24), bar at 84%
Iteration 7: increment(28), bar at 112% (disappears)
This is what you're doing. Is it really what you want? You'd probably be
better off using setPercent($p) where $p = 100/$maxsteps * $iteration

This is unnecessary. If the half-second delay after passing 100% is too
long, you can send "hidebar()" to hide it immediately.

RE: Displaying a status bar
Mark,
I set buffering to off ($| = 0) just before saving Excel Workook, it seems
to do what I want it to do. Even though I'm not setting the status bar to
100, it seems to disappear smoothly when the processing is done. BTW, here
is how I am looping to increment the status bar.
$n=0;
While ($i) # $i = 7
{
...
$n = $n + 4 # I had to play with this number to make it work,
finally 4 seems to increment well.
print "increment($n)";
}
...
$| = 0;
501 $Workbook->SaveAs($path);
502 $Workbook->Close();
503 $Excel->Quit();
504 sleep(1);
505 print h2("Query Completed");
506 print $r->end_html;
Mark, thanks for your help and the status bar script.
Lee, thanks for you suggestion, I did use sleep just to delay a sec. for the
bar to disappear, before printing.
Regards,
David

How are you incrementing the progress bar? Perhaps it's getting to 100%
before your setPercent(100) call, and automatically disappearing. Try
removing the setPercent(100) and see if the bar still disappears.
If that test shows that the bar remains on the page to the end, try putting
the setPercent(100) in the body onload event, i.e.
- Mark.

Re[2]: Displaying a status bar
0002 $| = 1;...
5010 $Workbook->SaveAs($path);
5020 $Workbook->Close();
5030 $Excel->Quit();
5040 print "setPercent(100)";
5050 print h2("Query Completed");
5060 print $r->end_html;
Sorry, I don't know the JavaScript you're talking
about. But,
What happens if you make like 5035 (above) read
sleep(10);
Does the bar pause?
What's the $r object? CGI or mod_perl or something?
Make sure you have whatever it is send the correct
headers *before* anything else, and that the other
HTML elements are "good", otherwise the browser may
be doing unexpected things.

RE: Displaying a status bar
Thanks Mark for the status bar.
It seems to work well and definitely what I want, but the status bar is
disappearing too soon, even though I am controlling when to disappear. I am
not sure why it is skipping the other code and processing the code where I
tell the status bar to disappear. Here is the last part of my code after
all processing. I am querying all the data into Excel and saving it.
$| = 1;
...
...
501 $Workbook->SaveAs($path);
502 $Workbook->Close();
503 $Excel->Quit();
504 print "setPercent(100)";
505 print h2("Query Completed");
506 print $r->end_html;
I can put line 504 at the end (line 507) and it would still process it
first. The thing is that once the status bar disappears, I am still waiting
(~ 45sec) before line 505 is printed. I think it is still processing the
Excel workbook because the saved file has not appeared.
Any ideas?
David

Your problem may be output buffering. Put $|++; in your program before
sending any output and you can then print html to the screen.
That being said, I've created a javascript library that puts a graphical
status bar on the screen, and the percentage, overlay text, and color can be
set by a perl program as it running, and at the end, it disappears so as not
to interfere with the output. It's useful for long-running programs. Contact
me off-list if you want it.

RE: Displaying a status bar
Mark, Thanks for your suggestion. I set the output buffer to Off, and it is displaying my html status bar and it seems to be processing in the background. But, I want to display my results page after processing. It seems that the status page does not "go away" even after processing is done. I have added the print out of data after the processing steps in my code. My data sets are sometimes large and small. During the smaller data sets, the processed data would be displayed on the same page as the status bar. The larger data sets, it seems it would always stay on the status bar screen, without displaying any processed data. Any thoughts on this.
