Please note that mlogger does not work (crashes on run start) starting with svn
rev 4858, fixed in svn 4862. If you have to use this busted version of mlogger,
the crash is fixed by update of history_midas.c to svn rev 4862 or set ODB

We had javascript ODBGet() and ODBSet() functions for some time now, permitting implementation of
"page-reload-free" "self-updating" web pages. I finally got around to put all the javascript bits together
to actually implement such a page. The main difference from a normal MIDAS "custom" page is the data

As of svn rev 4794, midas builds, runs and should be fully usable on MacOS 10.6.4. Previous revisions did
not compile due to assorted Linuxisms and did not run because of a sizeof() problem in ss_gettid(). Also
one of the system header files (mtio.h?) present in MacOS 10.5 vanished from 10.6.

As of svn rev 4807, src/system.c has an experimental implementation of POSIX shared memory. It is
similar to the already existing implementation of MMAP shared memory, but uses POSIX shm_open()
instead of directly mmapping the .xxx.SHM file.

09 Feb 2010, Stefan Ritt, Forum, custom page - flashing filled area
|
One possibility is to use small GIF images for each valve, which have several frames (called 'animated GIF'). Depending on the state you can use a static
GIF or the flashing GIF. An alternate approach is to use a static background image, and display a valve with different color on top of the background in
regular intervals using JavaScript. I tried that with the attached page. Just create a custom page
/Custom/Valve = valve.html
and put all three attachments |
