There is a testcase available a Java Bean MyButton.class.

Here is the text from the readme.txt in the test case :-
    MyButton is just a button that fires a MessageEvent
    to a MessageListener via the showMessageBox(MessageEvent e)
    method.

    ReceiveEvent implements MessageListener and puts up
    a dialog with the message in MessageEvent when it gets
    the event from showMessageBox.

    This works wonderful in the java world. You can use the
    MyButtonTest.html in appletviewer to test this. It's a
    blow and go demo, you shouldn't need to do anything but
    load the html file unless I screwed up something.

    HERE'S THE PROBLEM:

    When running this as an ActiveX control in VB5, the
    dialog will be displayed, but only half painted, and
    then VB and the dialog will hang.

    I think the problem is this: ReceiveEvent.showMessageBox
    displays a modal dialog. Modal means Dialog.show doesn't
    return until the user hits OK. But the user can't hit OK
    because the dialog hangs. Is it hanging because it's locked
    out the main UI thread ?
