External Directx Source (C++)

Anyone have an external directx source i can look at? Just looking for one that is really straight forward and easy to read. Like a simple external crosshair source or something. I looked at the well coded esp source that gtaplayer released but theres a lot going on there, and i'm just trying to learn how to initialize directx in a simple way. Thanks guys.

EDIT:
Would have posted this in c++ forum but i figured a lot of csgo guys would have experience with this. Source code does not have to be from counterstrike i just want something simple and external if at all possible.

Here's an external crosshair, http://www.mpgh.net/forum/showthread.php?t=1046468

Will edit if i find this old dx post.
