Determining 64-bit vs. 32-bit Windows
提问by LeeMobile
I'd like to configure visual studio 2005 to copy .dll's based on whether the OS is 64-bit or 32-bit during a build.
我想根据操作系统是 64 位还是 32 位在构建过程中将 Visual Studio 2005 配置为复制 .dll。
I do not want to specify what the platform target is.
我不想指定平台目标是什么。
My first attempt was to use a batch file to lookup the Windows version, but some 32-bit and 64-bit versions of Windows share the same version number.
我的第一次尝试是使用批处理文件来查找 Windows 版本，但某些 32 位和 64 位版本的 Windows 共享相同的版本号。
Anyone know of any way to check this?
任何人都知道任何方法来检查这个？
Thanks!
谢谢！

Jon's link is a total hack because it relies upon no new processor architectures being added.
Jon 的链接完全是黑客攻击，因为它不依赖于添加新的处理器架构。
