Hello
I am a 18 year old Indian Engineering student
I have learnt various web programming languages like HTML- DHTML- XHTML- Javascript - CSS
And also languges like C++ and CoreJava

But all of them through the internet so there is no certificate of a legal document to prove that i know all these perfectly

So can anyone tell me if there is an international degree for which i can apply and give examinations just to prove that i know all these languages very well on paper ?

And how do i apply ?

Please tell me - I really need to get this done
Thanks in advance

It happen since last nite- when ever i play a youtube video it will show this:
"Hello- you either have JavaScript turned off or an old version of Adobe s Flash Player. Get the latest Flash player. "

I then tried using opera and firefox- both didnt show this error msg but it load quite slow. while for other website like metacafe works perfectly well.

so i dont think its my java/flash problem.
any1 know wats the problem??

Response.Write("...

while(Item == TestVal2)
