NOw I have already tried the following three methods to no effect:

Method 1:
1.      Click Start, and then click Run.
2.      In the Open box, type Regsvr32 urlmon.dll, and then click OK.

'aDDEventListener' is spelt rather oddly - is it a problem with case sensitivity?
RGuillermoProject ManagerAuthor Commented:
I honestly can't tell,
is there any sort of test that I can do?
Thank you

Check if it is spelt correctly with the case of letters.  (eg. With case sensitivity Add and aDD are two different things).

"Simplest" probably doesn't support JavaScript does it? If not, you'd be out of luck with most pages on the Internet these days

But its not my website, I am browsing that site.. so even if I modify the code the next time will come the same
RGuillermoProject ManagerAuthor Commented:
I see, how can I verify if it supports JS
please ?
The simplest thing is to use a JS tester page. Use a different browser to find one
RGuillermoProject ManagerAuthor Commented:
yes, JS is working on IE and Chrome
is it possible to make it work in my c# project ?.
I don't know, since i don't know if your components support it. You need to check
