ActiveXObject versus CreatObject

[Michael Arbel]

Hi,

Could you please tell me why :

<script language="VBScript"><!--
On Error Resume Next
set control = CreateObject("ACTIVESURFER.ActiveSurferCtrl")
if err.Number then
isSurferInstalled = false
else
isSurferInstalled = true
set control = NULL
end if

Work Perfect!

while this:
<script language="JavaScript"><!--
function ActiveSurferError(msg,url,lno)
{
isSurferInstalled = false;
return true;
}
window.onerror = ActiveSurferError;
var control = new ActiveXObject("ACTIVESURFER.ActiveSurferCtrl");
alert(control);
control = null;

cause the IE5 to shut down.

Thank you very much
Michael A.

You might want to ask this in a newsgroup about Javascript, instead of one
about Java.

The difference is simply in the language. VBScript has an intrensic function
call "CreateObject" which creates a new instance of an ActiveXServer or Components
in the browser. However, JavaScripts equivilent is ActiveXObject. I am
sure this comes from the fact that ActiveX is a Microsoft specific technology
and javascript has evloved to support it.
