SwapImage with Set cookie - Get Cookie , Optimizing for internet explorer ?

Question

Hello
I have a soon- to -be -published website. The homepage, index has quite a lot of session - cookies on it, which are connected to swapimage behaviour. They work fine in firefox, opera, Safari and chrome, but in Internet explorer the swapping of the images takes a looooooot of time.....
Also, when  I reload the page, some of the cookies are not retrieved, which only happens in Internet Explorer.
This is the inline javascript for the page:
<script type="text/javascript">
function MM_swapImgRestore() { //v3.0
  var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc;
function MM_preloadImages() { //v3.0
  var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
    var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
    if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
function MM_findObj(n, d) { //v4.01
  var p,i,x;  if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
    d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
  if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
  for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
  if(!x && d.getElementById) x=d.getElementById(n); return x;
function MM_swapImage() { //v3.0
  var i,j=0,x,a=MM_swapImage.arguments; document.MM_sr=new Array; for(i=0;i<(a.length-2);i+=3)
   if ((x=MM_findObj(a[i]))!=null){document.MM_sr[j++]=x; if(!x.oSrc) x.oSrc=x.src; x.src=a[i+2];}

As you can see there are a lot of function calls with getElementById, and I'm thinking there has to be a more efficient way of doing this....... I am using an external cookieScript for setting and getting the cookies, but the swapImage is standard Dreamweaver.
I would be very happy if anybody could help me with this.. I know it is probably easy when you know how, but I don't, unfortunately :-(

Hi JMH_NG,
Thanks for the post and I hope your well today. I noticed you've not received any support so far.
It is possible in LabVIEW to access the ActiveX event callbacks
for the WebBrowser object. The "ActiveX Event Callback for IE.vi" is a
good example found in the Example Finder that demonstrates this
capability. The ability to poll whether the download is complete will
be completely dependent on the DWebBrowserEvents that the WebBrowser supports. FileDownload will notify when a download file download begins. From Microsoft's MSDN page,
"When the WebBrowser control is about to begin a download operation, it
fires the DWebBrowserEvents2:: DownloadBegin event." A DownloadComplete
event is also fired when the download operation finishes. From the
information I've found, it sounds like these events (and
ProgressChange) are only for page downloads and not for file downloads,
but they are your best bet. I would suggest inquiring on the MSDN Forum for more information on these events.
I hope this helps,
Kind Regards,
James.
