Is there a question about Nasm in there somewhere??? If all else fails, you might try the Friendly Manual... (Nasm manual or Fasm manual, depending on which you're actually using)

Best,
Frank

Okay... parameters to a Windows API are almost always dword... "push dword [100]" will attempt to push the contents of memory at "100", which will probably cause an access violation - you probably want just "push dword 100"...

I would suggest joining the Yahoo "win32-nasm-users" group - http://groups.yahoo.com/group/win32-nasm-users (http://groups.yahoo.com/group/win32-nasm-users) - in the "files" section, you'll find a number of examples, ranging from simple to more complex... and can get questions answered, too. I personally don't know much Windows programming (*my* examples are the "simple" ones :)

Best,
Frank
