build C++ COM for 64-bit platform
I am developing C++ COM native code (unmanaged C++) using Visual Studio 2005. I do not take any new features of 64-bit platform, and currently my code runs fine on 32-bit platform (e.g. Windows XP SP2).
Now I am researching how to build my code for 64-bit platform (e.g. Windows 2003 Server 64-bit R2)? Any options I need to specify in Visual Studio 2005? The best solution to me is to make a single build for both 32-bit and 64-bit platforms, is that possible?
thanks in advance,
