Title: Report timeouts
Post by: LyGilCo on July 31, 2008, 07:02:04 PM

Hi All,
          I have a webapp that generates reports, these work fine however if a report is large the client browser times out.

The solution as I see it is to send a 'I am still here' packet (of anything) to the client browser at regular intervals to keep it interested.( I do this with charts using p_web.ParseHTML in validaterecord.)
However in reports - as the PDF is being generated (which can take some time) there seems to be no hook (timer) in which to send  'I am still here' packets.

Any ideas?

TIA

Murray

I'm responding to this topic because it is a priority of mine as well, and I haven't seen any solutions yet. I also have a report that times out if there is much data. I've not a clue how to keep the page alive. Help? MikeG

Some of my reports are 90+ pages.

a Solution to this would be great.

My feeling is that is might involve hacking the report to pdf templates / class

Not a good option

And not just reports Murray, I started building some stuff with Office Inside to generate XLS files and it times out as well. I suspect there could be many other things we might want to do that will have problems as well.

I can probably figure out how to keep the page alive. I'm not so sure I can figure out when the process has ended. I'm thinking I could do a loop of empty packets or something until I detected the event had finished. Haven't had time to work out the details yet.

Hi Mike,
             Yes I suppose one way would be to have a 'watchdog' thread
which will send packets to the page.
You could start the thread when the report or whatever starts, the send a 'die' event to the thread when the report ends.

Cheers

Gee whiz, but you're a bunch on whiners aren't you.. :)

I've added some code which should sort this issue out in 4.32.
For ABC and Legacy reports it's built-in. For other reports, and other situations,
I'll post into the Share Knowledge forum.

Cheers
Bruce
