ActiveX event capture question


I'm confused why I can capture an event fired by an ActiveX object when
it's loaded via an <object> tag, but not when loaded using "new

Here's a basic example:
vb ActiveX object:
Private Declare Sub Sleep Lib "kernel32" (ByVal dwmilliseconds As Long)

Public MyProp As Integer

Public Event doPop()

Public Sub FireEvent()
Sleep (2000)
RaiseEvent doPop
MyProp = 3
End Sub

Private Sub Class_Initializ e()
MyProp = 1
End Sub
javascript using the script to load the object:
(This way loads the object - I can get property values.
I just can't capture the event).


<script type="text/javascript">

var VBxSignaler
function loadTheObject()
try {
VBxSignaler = new ActiveXObject(' TestControl.VBx Signaler')
} catch (e) { alert( "oops" ); }

function doAlert() { alert( "It caught the event" ); }
function fireTheAlert() { VBxSignaler.Fir eEvent(); }
function getProp() { alert( VBxSignaler.MyP rop ); }

<script type="text/javascript" for="VBxSignale r" event="doPop">

<body onload="javascr ipt:loadTheObje ct();">

<input type=button id=button1
onclick="javasc ript:VBxSignale r.FireEvent();" value="Fire" /><p>

<p><input type=button id=button2 onclick="javasc ript:getProp(); "
value="Get new Val" /><p>

This is using the <object> tag.
This way allows me to capture the event.
Any help would really be appreciated.


<div style="display: none">
id="VBxSignaler "
classid="CLSID: B84143D2-3ADB-48E1-9716-05B77BB982B5"
style="display: none;">

<script type="text/javascript" for="VBxSignale r" event="doPop">
alert( "I just caught the event!" );

<b>This contains the "object" tag</b><br>
<input type=button onclick="VBxSig naler.FireEvent ();" value="Fire"

You might want to ask the experts in the MS scripting newsgroups but
ActiveXObject does not provide event binding as you have found out.
For instance when you use JScript in WSH (Windows Script Host) scripts
you do not use ActiveXObject to have events bound but you need to use
WScript.CreateO bject.

Thanks Martin. Good thought... also always nice to find out I'm not
just losing my mind.

I know this question has been asked a million times but I still can't get an event from an embedded ActiveX Exe to be caught in javascript.

Hi I need to capture a mouse click event when inside a visual third party ActiveX which unfortunately comes without published events. In Win32 I used to manage such problems on Application level with WM_ messages, but almost beginner in .NET & C# environment, I don't see the solution, which is probably trivial for experienced people. Any help?
