Let's say I have an html form with 20 or 30 fields in it. The form
submits the fields via POST to a php page which updates a table in a
database with the $_POST vars. Which makes more sense?
1) simply UPDATING the values for all fields in the table, whether or
not any particular field has actually changed
2) running a second SELECT statement and comparing the $_POST vars to
the returned values, and only UPDATING those that have...

Hi,
Is it possible to verify, using js, if ANY item in a form has changed?
For example: I have a <form> with multiple items (<input>, <select>,
<textarea>, etc). I need to track if one (or more) of this items has
changed by a user.
One option, is to put a onChange event in each one of these fields
and, if the event occurs, I will update a hidden input to indicate

I have a problem that I figured would be relatively common, but have

I created a database which my company has used for over 2 years at now
over 30 locations. Just today, one of the locations called and was
having problems with their program. The database is A97 runtime with
split front/back ends. They sent me their back end file, and 2 of the
columns in their Events table, all were somehow changed. One of the
values changed all changed to 0's, and the other all changed to 1's.

I would like for when a tab page changes, that my controls on the previous
tab page would receive a visiblechanged event or some other event so they
are aware of that. We have db locks in some of our controls when they're
visible and so if a tab page is changed, I would like for the control to
know it's no longer visible and release that lock. Currently that doesn't
happen. Does anybody have any suggestions and/or is this a bug?

Hi everyone,
How do you detect that a form element has been changed? This thread:
http://groups.google.com/group/comp.lang.javascript/browse_thread/thread/9ae1c9d419264380/125a82c9be127790?lnk=st&q=checking+html+form++(updated+OR+edited+OR+changed)&rnum=28&hl=en#125a82c9be127790
suggests that you attach onChange event handlers to every form element,
and when the handler fires you update a global 'isChanged' variable.
This technique...

Hello,
I have a form where I want to only enable a save button when something has
changed in the dataset. Currently I'm checking current values against
original values everytime a value is changed to enable/disable the save
button. Is there a way of telling if a dataset has been changed (ds
property?) other than using this method?
Any help greatly appreciated!
Thanks in advance

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
