Calling a dll from a new menu item in Bridge. Idiot help needed

Question

Hi,
I'm trying to what I believe is a fairly simple script.  I'm coming from a hobbiest Delphi background, and to be honest I'm finding JavaScript a little bit hard to understand.  My requirements are simple - add a new menu item to Bridge which executes a call to a custom dll.  Note I'm not expecting the dll to return anything here.. 
Looking at the samples provided even I can add the menu item - but getting it to successfully call the dll is a bit of a mystery. 
The script compiles and adds the menu item, however the menu action doesn't call the dll.  I believe it should be a fairly simple task and was hoping somebody here could steer me right.  Here's my code (as you'll see a clear cut and paste job from the examples ;o)
Header 1
function SnpAddMenuItem()
  this.requiredContext = "\tAdobe Bridge must be running.\n\tExecute against Bridge CS6 as the target.\n";
  this.menuID = "snpmyMenu";
  this.menuCommandID1 = "snpAddMenuItemSub1";
  $.level = 1; // Debugging level
SnpAddMenuItem.prototype.run = function()
  var retval = true;
  if(!this.canRun()) {
  retval = false;
  return retval;
  // Create the menu element
  var newMenu = new MenuElement( "menu", "myMenu", "before Help", this.menuID );
  // Create the menu item
  var alertCommand1 = new MenuElement( "command", "Load Stuff", "at the end of " + this.menuID, this.menuCommandID1);
  alertCommand1.onSelect = function (m1)
        ExternalObject.myDll = new ExternalObject('lib:/C/temp/apmDLL.dll');
        myDll.sendtoACRPM(1);
//      return retval;
SnpAddMenuItem.prototype.canRun = function()
  // Must run in Bridge
  if(BridgeTalk.appName == "bridge") {
  // Stop the menu element from being added again if the snippet has already run
  if((MenuElement.find(this.menuID)) && (MenuElement.find(this.menuCommandID)))
// $.writeln("Error:Menu element already exists!\nRestart Bridge to run this snippet again.");
// return false;
            MenuElement.remove(this.menuID);
  return true;
  $.writeln("ERROR:: Cannot run SnpAddMenuItem");
  $.writeln(this.requiredContext);
  return false;
if(typeof(SnpAddMenuItem_unitTest ) == "undefined") {
  new SnpAddMenuItem().run();

The dll needs to be compatable with the criteria set in the JavaScript Tools Guide. There is an example in the Bridge SDK that can be downloaded from http://www.adobe.com/devnet/bridge.html
But it need someone who is knowledgeable with c++
It would be great if someone could write a wrapper to access other external objects.
