Hi,
I have a form in which i want to disable the functionality for using CUT and PASTE using either by CTRL C and CTRL V or by MOUSE right click.
I tried using comapring event.controlkey and event.keyCode but it looks like in IE4 and above there is a different character code .
Can any one help me out where i can get this CONTROL KEY CODE List for IE4.

Thanks

Ask IE 4 --

Code: 
  var aK = new Array(2)
  aKClr()

function getKeyCode(state) {
  aK[state] = event.keyCode
}

function aKShow() {
  alert("keyDown "+aK[0]+"\nkeyPress "+aK[1]+"\nkeyUp "+aK[2])
  aKClr()
}

function aKClr() {
  for (var i = 0; i < aK.length; i++) {
    aK[i] = -1
    }
}

called by --

Code: 
<body onload=&quot;document.all.pcIn.focus();&quot;>
Type a key
<input type=&quot;text&quot; id=&quot;pcIn&quot; maxlength=&quot;1&quot; size=&quot;1&quot;
  onkeydown=&quot;getKeyCode(0);&quot; onkeypress=&quot;getKeyCode(1);&quot;
  onkeyup = &quot;getKeyCode(2);aKShow();this.value = '';&quot; />

CTL-C returns 67 for keydown/up, ignores keypress. CTL-V returns 86, ignores keypress (and pastes first char from clipboard). You may be asking too much of IE 4 as Cut/Paste functionality may be inherited from Windows, there whether you like it or not.

var aK = new Array(3);
aKClr();

function getKeyCode(state) {
aK[state] = event.keyCode
}

function aKShow(from) {

if((aK[0] == 65 && aK[1] == 97 && aK[2] == 17) || (aK[0] == 65 && aK[1] != -1 && aK[2] == 65)) {
aKClr();
}
if((aK[0] == 67 && aK[1] == -1 && aK[2] == 17) || (aK[0] == 67 && aK[1] !=-1 && aK[2] == 67)) {
aKClr();
}
if ((aK[0] == 86 && aK[1] == -1 && aK[2] == 17)) {
aKClr();
from.value=&quot;&quot;
}
return true;
}


function aKClr() {
for (var i = 0; i < aK.length; i++) {
aK = -1
}
aK[3]=-1
}


Hi,
I used your code and modify little bit. what happens here is when you to first time time CTRL A and CTRL C and CTRL V it is working . but next time the event is not firing . so i modify the same.
Secondly the counter should be made as -1 for 0,1 and 2nd array . now it is working
I am trying even Mouse right click but it is working if i keep alert message inside the condition . see this function

function rightClick() {

if (navigator.appName == 'Netscape' && (event.which == 3 || event.which == 2)) {alert(&quot;No&quot;);return false};
if (navigator.appName == 'Microsoft Internet Explorer' && (event.button == 2 || event.button == 3)) {alefrt(&quot;no&quot;);return false;}
}

If i delete the alert message it is not working. can you tell me why?

prudhivi,

make sure you only delete &quot;alert(&quot;No&quot;)&quot; and not &quot;alert(&quot;No&quot;);return false;&quot; ... the &quot;return false;&quot; part is what makes it work. ======================================

if (!succeed) try++
