   32/64 DLL question
  Hey all!Is it possible to build a 64bit DLL using visual studio 2003 on a 32bit windows xp box? if yes, how?   
  You can do it by cross-compiling. I don't think Visual Studio 2003 has a 64-bit compiler, but you can download the platform SDK, which does have one.   ;Quote:Original post by NDIRHey all!Is it possible to build a 64bit DLL using visual studio 2003 on a 32bit windows xp box? if yes, how?Short answer. No.  64-bit support started with VS 2005, then VS 2008, etc....See here:http://en.wikipedia.org/wiki/Microsoft_Visual_StudioIf you want to invest into something, I would recommend getting VS 2008.
