   lib directory - x86 x64 ?
  I just installed the april 2005 sdk of directx and I useda previous one before, there's a difference in the lib directory -it has two directories inside of it - x86 and x64 - Ineed to know which of these directories to use   
  x86 = classic x86. 32-bit mode.x64 = the 64-bit extensions. Only use this if you're running a 64-bit version of Windows.   ;  x86 are libs for well, x86 class processors, well, it's for pretty much any processor, it's 32 bit. x64, is for 64 bit only.
