JavaScript method to open Hummingbird/OpenText eDocs files via Desktop Explorer

dms.js

// This script is used to open files and folders
// in Hummingbird/OpenText eDocs Document Management System.
// Not the most elegant method, but the native API does not seem
// recognize how to open folders in the DMS, so I had to get old
// school and use ActiveX. Of course, this script will only work
// with Internet Explorer, so you may have to adjust security settings.

// Note: I think I can use the API to define a launch method, such as ACROBAT,
// MS WORD or even FOLDER, but I don't know how to use the API to determine which method
// to use, so ActiveX tom-foolery it is.

var currtime = Math.abs(new Date().getTime());

function openDMS(docid, tmppath){
	// use a timestamp to keep .DRF files unique to this session.
	var docname = tmppath + currtime.toString() + ".DRF";
	createReference(docname, docid);
}

function createReference(docname, docid) {
	try {
	// create a temporary .DRF file
	    var fso = new ActiveXObject("Scripting.FileSystemObject");
	    fso.CreateTextFile(docname, true, true);
	    var f = fso.GetFile(docname);
	    var ts = f.OpenAsTextStream(2, -2);
	    ts.WriteLine("Document;DMS;" + docid + ";R");
	    ts.Close();
	    delete fso;
	    delete f;
	    delete ts;
	    openDocument(docname);
	} catch(e) {
		alert(e.message)
	}
}

function openDocument(doc) {
    window.onunload = function () {
	// when the page is closed, delete the temporary DRF file.
        var fso = new ActiveXObject("Scripting.FileSystemObject");
        fso.DeleteFile(doc);
        delete fso;
    }
	
    // open the DRF via the Shell
    var oShell = new ActiveXObject("WScript.Shell");
