Hi all,
I'm developing a RIA in Flash and i need to disable the input of CTRL key in the browser.
Someone know how to do it (I think using javascript)?

Thanks

Thanks Anik, I'm using it now but it doesn't work in IE7...

The script is this one:

Code:

<script language="JavaScript">
function disableCtrlKeyCombination(e)
{
        //list all CTRL + key combinations you want to disable
        var forbiddenKeys = new Array(‘a’, ‘n’, ‘c’, ‘x’, ‘v’, ‘j’);
        var key;
        var isCtrl;

        if(window.event)
        {
                key = window.event.keyCode;     //IE
                if(window.event.ctrlKey)
                        isCtrl = true;
                else
                        isCtrl = false;
        }
        else
        {
                key = e.which;     //firefox
                if(e.ctrlKey)
                        isCtrl = true;
                else
                        isCtrl = false;
        }

        //if ctrl is pressed check if other key is in forbidenKeys array
        if(isCtrl)
        {
                for(i=0; i<forbiddenkeys .length; i++)
                {
                        //case-insensitive comparation
                        if(forbiddenKeys[i].toLowerCase() == String.fromCharCode(key).toLowerCase())
                        {
                                alert(‘Key combination CTRL + ‘
                                        +String.fromCharCode(key)
                                        +‘ has been disabled.’);
                                return false;
                        }
                }
        }
        return true;
}
</script>

And I'm using it like this:

Code:

<body onkeypress="return disableCtrlKeyCombination(event);" onkeydown="return disableCtrlKeyCombination(event);" leftMargin="0" topMargin="0">

Any idea?

Thanks
