Showing HTML Content over Flash Movie - quick and dirty way!

I had faced a nasty problem few days ago. I was to show user a modal-popup (in html page) for Terms and Conditions for registration on a site. Popup was coming okay, but There was a flash movie at top of the page which was hidding upper portion of the dialog. The tested and widely used method is to put an Iframe at place where you want to show your content and absolute position your content and IFrame. For example, if you want to show a div above a flash movie, then place a IFrame like follows:
        <iframe style="position:absolute;top:250;left:150;"></iframe>
Then position the div exactly above this iframe like:
        <div style="position:absolute;top:250;left:150;"></div>

I was using jquery on the page to show dialog using ui.dialog plugin.
After fooling around sometime I devised following simple solution.

1)  put id attribute on movie element to uniquely identify the movie object. Like,

<object id="movie1"></object>

2)  before showing the dialog (or other content for that matter) call a javascript function to hide the movie. Like,

$("#movie1").css("display","none");

3)  now show dialog. Like,

$("#dialog").dialog("open");

4)  after closing the dialog, show the movie again. Like,

     $("#dialog").dialog("close");

$("#movie1").css("display","inline"); 

that's all folks, Happy Coding

Working with Anthem.NET and AJAXControlToolkit CalendarExtender

I've wasted almost complete day to debug what now seems very trivial. I'm using Anthem.NET in my project. I almost exclusively use Anthem.NET in my ASP.Net applications for AJAX. Almost because I've to rely on AjaxControlToolkit for some capabilities, like Calendar and ListSearchExtender.
I'm using Anthem ListBox box, and some textboxes on a page. Listbox generates a callback and textboxes are populated async'ly. One of the textboxes is for date input. I've used CalendarExtender control to show dropdown (I just love it for this thing) calendar. When page first loads calendar shows nicely, but as soon as callback is generated, it stops working.
After looking at generated page, I found code responsible for creating client side calendar. It is this one:
Sys.Application.add_init(function() {
$create(AjaxControlToolkit.CalendarBehavior, {"format":"dd/MMM/yyyy","id":"MyCal"}, null, null, $get("ctl00_ContentPlaceHolder1_txtPurchaseDate"));

So, it seemed very simple register a PostCallback function for ListBox, with $create method in it, to recreate calendar everytime a callback occured.

So far so good, but it cropped up control with duplicate id problem. I tried $dispose method from ajax.net library, but it told me that element I'm looking for is unavailable. Then I tried prototype to remove the said element from the DOM tree, but it was also not able to find element.

Then after googling many times for many things (in the meantime reading scripts in AjaxControlToolkit source code, using reflector to go through System.Web.Extensions.dll and using firebug extensively) I got to Ajax.NET reference on asp.net (now, don't laugh at me that it is not in my delicious, as I've been relying mostly on Anthem.NET).

There I found the whole story at page for Sys class [here]. I used $find method to get my element and used removeComponent to remove previous instance before creating new one.
Sys.Application.removeComponent($find("MyCal"));
