For all you shellcoders out there; to make Windows API calling easier, you can use Stephen Fewer's block_api.asm in the Metasploit tree. http://www.metasploit.com/redmine/projects/framework/repository/revisions/8160/entry/external/source/shellcode/windows/x86/src/block/block_api.asm
But you need the function hashes, which if you don't have the DLL on your current OS, or the python file, or something like that can be annoying. So I posted a few that I calculated so you can just look them up.
