I want to create a screen recorder in WPF. I tried using Background Worker but it's not working.
I understand that i need to capture the screen and the do it in a loop but if i want to present it in a gui or save it in video format i can't.
If anyone has a general idea or an example it would be great.

Set up a camera on a tripod and snap a picture every time the screen changes.

It's pretty simple, but there are a few easy steps to take:
1) Learn to read.
2) Learn to take notice of what you are doing. Look at the top of this page. See the line:
Technical discussions are encouraged, but click here to ask your programming question. It's so important, we put half of it in red so nobody could miss it! But you did. Why? Because you couldn't be bothered with the little details.
And it's probably the same with your code. Your description of the problem certainly implies as much: "it's not working". What kind of help is that when it comes to fixing your problem, huh?
It a user emailed you and said "it's not working" and nothing else, I'm pretty sure you would have a long list of questions for him, or delete the email. So why do you assume that we should be any different?
Take it here: http://www.codeproject.com/Questions/ask.aspx[^] - but...ask a question that people can help with. Think about the poor sod on this side of t'interwebs and try to help him. Show what you have tried - relevant bits only - and explain what you have done to try and sort it.
But a general "tell me how to do it" - even posted in the right place - is not going to get you much help.
And learn to look before you post!

So, I did a quick google search for "delphi tpair" because I couldn't remember what unit it was in off the top of my head. Google returned the page I was looking for as the first result, but I was greeted by this description under the link:
"A description for this result is not available because of this site's <a href="http://docwiki.embarcadero.com/robots.txt">robots.txt</a> – learn more."
Why in the hell would Embarcadero not want webcrawlers (i.e. Google) reading through their wiki? That makes absolutely no sense to me...

For those who don't know, a "float" is a scoop or more of ice cream (usually vanilla), in a glass, then some flavored soda (aka "pop" ...think Coke but don't stop there) is poured over it.
A float, aka an ice cream float, was one of my favorite childhood summertime treats. Last night we topped all I've ever had before.
We started with a supreme ice cream[^], one that is so good a writer for the New York Times said it was worth the trip to Cincinnati. That's like a Parisian saying some food in Dover was worth the trip in January.
One of my favorite flavors for the soda is something called "root beer". [^] Normal root beer is basically a tea made from bark and roots of trees.
Well...my favorite daughter favorite boyfriend brought over some Not Your Father's Root Beer...[^]
Yum!

Ah memories! As a kid, Vernors over vanilla ice cream.
It's a Detroit thing. You wouldn't understand.

We made ours with Cream Soda[^] instead of root beer and it was called an "Ice Cream Soda".
I remember my grand parents had anodized aluminum glasses that were only used for that (eaten outside around the pool)
I'd rather be phishing!

Interesting - I had never considered it before.
Ice cream in a glass of soda was called an ice cream soda.
Yet, there was, indeed, an item specifically called a root-beer-float.
Like any rational person, in times of great personal trauma, I turned to Wikipedia.
Looking up Root Beer Float I ended up on the Ice Cream Soda page.
So, as a brad is a nail, and a palomino is a horse, so to we have our confusion assuaged.

Don't even get me started on Graeters... I might have to make the extremely strenuous 5 minute walk there tonight...
As far as floats go, vanilla ice cream with orange soda is pretty darn good. Also, I did Dr. Pepper with chocolate ice cream once, which was quite tasty.

Picked up 3 pints for under $15 last weekend. Would have done 4 but when I did that last year I ended up in the hospital for "gas" (Cardiologist has a different opinion, the punk kid!). My hospital room was ground level. Across the way, the sign on a Graeter's shop mocked me for 4 days.

Can you say "Dreamsicle/Creamsicle"?

Exactly. I once had some orange cream soda that tasted exactly like that, but when I made the float, I only had normal orange soda.

IMHO, the only way to eat icecream is with a spoon.

No reason you can't have a root beer float with a spoon. 
How about an ice-cream sandwich? Ice cream between 2 homemade chocolate chips cookies. 
There are only 10 types of people in the world, those who understand binary and those who don't.

The only thing I want in my sandwich is ham. Ham, beautiful ham... and salami. Mmmm...
