Re: Scripting question...

["Bradley Gabe" <withanar(at)gmail.com>]

They both create the same collection object.

 

The main difference , I think, is instantiating the new ActiveXObject only works when you are inside the XSI scripting envrionment for jscript/vbscript. If you are writing an application using the MS scripting framework outside of XSI, such as a Netview or web interface for XSI, you'll need to access the XSI object factory to instantiate XSI specific collections.

Yeah, your right, I interpreted this from VBScript code in XSI docs. I
rarely use VBScript and I assumed that it was directly interchangable
with JSCript. This raises an interesting point though. I was unaware
that there are commands derived for specific languages as opposed to the
languages only changing the basic constructs and syntax. I see from the
man pages that these are accepted methods for creating an XSICollection.

VBScript
   Set oColl = CreateObject("XSI.Collection")
   set oColl = XSIFactory.CreateActiveXObject( "XSI.Collection " )

JScript
   var oColl = new ActiveXObject("XSI.Collection") ;

   var oColl = XSIFactory.CreateActiveXObject("XSI.Collection");

So I think the question I really meant to ask was what is the difference
between

   var oColl = new ActiveXObject(" XSI.Collection") ;
and
   var oColl = XSIFactory.CreateActiveXObject("XSI.Collection");

You've answered that in how it might relate to NetView, but if you are
not writing scripts to be used in NetView is it otherwise assumed that
they are identical commands? I've been using XSIFactory, I wasn't sure
if this was considered the norm or the exception.
