OpenGL Superbible Chapter 13 issues

Okay so im having issues trying to the get wglChoosePixelFormatARB functions to work properly. For some reason it cannot find any suitable pixel format... I have a decent graphics card (NVIDIA GeForce GTS 250) and have updated the drivers, I dont see why its having an issue. There are no issues with glew as far as i know. I dont understand why i'm having this issue. I've inluded the code, its taken straight from the google code project superbible 5th edition source. This is a screenshot of my console showing the error messages the code produces: http://imgur.com/G0bAA Any ideas as to what could be causing the issue?

wow awesome! I still get only a black screen using the fixed code, but i got my window! I swapped in other openGL code and have that running using thta as a window though! Thanks a bunch! I really appretiate it!
