code in driver

hello there,
I'm a newbie in the world of writing drivers. I noticed that it is a whole different way of programming then when you develop an application.
My question now was if it is possible to use code I use to create an application in the code from my driver.
I need to develop a screen capture driver. My driver needs to see the desktop as a camera source so Flash can grab it and stream it to other users.
