Explicit ActiveXObject deletion

Question

Hi,

I'm writing a JScript that opens an xml document using an ActiveXObject Microsoft.XMLDOM. And as I understand it, JScript uses auto-garbage collection, so that all dynamically allocated objects are deleted on script exit. The thing is, I am running this JScript from the Windows Speech Recognition Macros (WSR Macros) application environment.

My code runs fine the first time, but when I rerun the WSR macro, it either tells me "The process cannot access the file because it is being used by another process", or if I run with a different request, the dom document keeps the previous request data.

I am thinking that this might be because WSR Macros application might not interface with the .NET JScript parser/engine correctly (I have a very limited understanding of the .NET framework). Possibly because it does not handle script exiting particularly well?

My question is, is there a way to explicitly delete (or reinitialise to null/empty) an ActiveXObject (dom object) in JScript.

<script language="JScript">

<![CDATA[

           

      // Variables

      var guard_xml_doc;

      var load_ok;                 

                 

      Application.Speak("One moment");

      // Create dom document, load and parse xml

      guard_xml_doc = new ActiveXObject("Microsoft.XMLDOM");

      guard_xml_doc.async = false;

      load_ok = guard_xml_doc.load("C:\\Users\\Dr Mac\\Documents\\My

                                           Apps\\guard_fp_tagout.xml");

      if (load_ok != true)

      {

            Application.Speak("Load Failed");

            Command.Exit();

      }

]]>

</script>

Any help would be greatly appreciated, thnx, Bruce.
