I have an <input> box and i want to disable the apostrophe ( ' ) key, so
when you press it, no character appears in the input box. All other keys
should work ok.
I can trap the keypress event using "onkeypress=myK eypressHandler( )" but,
beyond that, I'm stuck. I forget how to detect what key was pressed or how
to "null it out".
I'm using IE6 and users will be IE5.0 upward ONLY (trust me on this, suffice
to say it's not a website but an intranet application).
Any ideas please?
Thanks!

<input type="text"
onkeypress="ret urn event.keyCode != '\''.charCodeAt ();">
But note that the right arrow key -> has the same keyCode as the '
character so you will cancel that key too.

Not overhere, here the arrow gives no event.keycode at all.
<input type="text"
onkeypress="win dow.status=even t.keyCode;

<form>
<input type="text" name="yourInput " onkeypress="ret urn

<script type="text/javascript">

var k;
if (e && e.which) { // NS
k = e.which;

Although your users may wonder if there is something wrong with their keyboard
when they hit an apostrophe and nothing appears.

Right, I forgot that IE has its very own way of firing the different key
events for such keys, it fires no keypress but only a keydown for the
arrow keys so an onkeypress handler doesn't fire for arrow keys and
therefore doesn't run the risk of cancelling those.

I thought I would update an old page on which I had used a
<INPUT TYPE=image ...>
with a
<BUTTON><IMG SRC=...></BUTTON>
The problem is that <BUTTON> always provides a shadow/emboss effect.
Can I get rid of that? If the old <INPUT> button has been deprecated in
favor of <BUTTON>, have all it's button functions been duplicated?
Thanks for any help,

When the form is submitted, it is redirected back to itself, where it checks

If the default values are set, this is the visitor's first time to access

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.
