    I have written a script that gets trigered by IE's toolbar button. In
    this script I would like to asign an event handler to an element of the
    document currently open in IE. The way one access the document object
    from a toolbar button script is:

    var doc = external.menuArguments.document;

    Now assuming the document has an element called TextArea1, the logical
    thing to do would be:

    parentwin.document.all('TextArea1').onkeypress = new

    Which goes compiles and runs, except the event handler does not get

    Another trick i tried is as follows:

    var s = parentwin.document.createElement('script');
    s.text = 'window.alert(\'asdf\')';
    s.htmlFor = 'TextArea1';
    s.event = 'onclick';
    parentwin.document.scripts[0] = s;

    Same result.

    I would appreciate any suggestions you might have.

    Shouldn't that be "doc"?
    I would try it this way (untested quickhack):

    var myWindow, myDocument, myElement;
    if ((myWindow = external.menuArguments)
    && (myDocument = myWindow.document)
    && (myElement = myDocument.all('TextArea1'))
    ) {
    myElement.onkeypress = function() {

    ciao, dhgm
