True, but sometimes you may need to still use On Timer since CALL FORM doesn't always execute in a new cycle, i.e. if you make a change which needs the form to be redrawn before the things you want to do with CALL FORM run, you still need to use On Timer (or POST OUTSIDE CALL) instead as it is possible the CALL FORM will execute in the current cycle. ** 4D Internet Users Group (4D iNUG) Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **

Re: Set Time question
Just to add a little more to this. I suspect a number of readers already realized a really simple solution to this specific case is to simply test the read/write state in the On timer form event and NOT update if it's read write. This turns out to be a better solution in my case because it's a single place to test it vs. multiple points in the code otherwise. Easier to read and understand. However, it's also totally effective to just change toggle the Set timer event on and off as Arnaud suggested, and in a different case could be better. Once more this turned out to be more of a question of how to look at the problem.

Re: Set Time question
Hi Arnaud, Aha. That hadn't even occurred to me. I think that's exactly what I was looking for. Off the top of my head I think using the On Before Data Entry for listboxes and On before keystroke for fields. Thank you!

Each new SET TIMER "kills" the previously set one, so it allows to postpone or cancel next 'On timer'. For example when the user types into a search box, send the query after he has stopped input since one or 2 seconds. Maybe something like this in form method could work: jobPostponed:=60*2 //2 seconds, for example case of on keystroke set timer(jobPostponed) on timer set timer(0) job.do(please) set timer(jobPostponed) end case Thinking after, there is surely more events to consider (On click, double clic, menu, etc.) -- Arnaud de Montard ** 4D Internet Users Group (4D iNUG) Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **
RE: Set Time question
Kirk, You can create an independent process that is hidden to user which simply wakes up, does the calculation, and then calls the process. It you use IP variables you can have them auto-update based on the call to the process. We do this for projects that require this type of updatingno real interruption to the user. Just one thought..
