如何得到操作系统确切的版本信息？

[beizijing]

目前觉得有两种方法可行，可是都有相同地问题：
1.通过查注册表：在HKEY_LOCAL_MACHINE\software\microsoft\windows nt\currentversion键值下可以看到相关的信息。

问题：可是都是数字，我怎么可以确切地知道是那个版本，如可以判断是Windows 2000 Professional、Windows 2000 Server
、Windows 2000 Advanced Server或是Windows 2000 Datacenter Server？


2.通过windows函数GetVersionEx和OSVERSIONINFO结构可以得到，或是Environment可以得到版本地相关信息，可是也还是存在上述问题

以上两种方法，我只能知道是win2000，却不能知道是Professional、Server、Advanced Server还是Datacenter Server，

请问还有什办法可以知道详细地操作系统的版本的信息，请指教

楼上的，这个程序会出这个错误：error C2039: 'wProductType' : is not a member of '_OSVERSIONINFOEXA'
d:\microsoft visual studio\vc98\include\winbase.h(7998) : see declaration of '_OSVERSIONINFOEXA'
为什么？谢谢！

更新你的sdk

[mahatma_cn]

Windows NT/2000: Requires Windows 2000.
Windows 95/98: Unsupported.
Header: Declared in Winnt.h; include Windows.h.
Unicode: Declared as Unicode and ANSI structures.

[beizijing]

更新vc中的sdk，还是我操作系统的sdk？
可不可以说的详细一些？麻烦了

[mahatma_cn]

http://www.microsoft.com/msdownload/platformsdk/sdkupdate/

[beizijing]

我用是vc6.0，在它的msdn中定义的OSVERSIONINFOEX的结构为
typedef struct _OSVERSIONINFOEXA {
DWORD dwOSVersionInfoSize;
DWORD dwMajorVersion;
DWORD dwMinorVersion;
DWORD dwBuildNumber;
DWORD dwPlatformId;
TCHAR szCSDVersion[ 128 ];
WORD wServicePackMajor;
WORD wServicePackMinor;
WORD wReserved[2];
} OSVERSIONINFOEXA, *POSVERSIONINFOEXA, *LPOSVERSIONINFOEXA;

可是在其它的文件中，如.net中的定义为：
typedef struct _OSVERSIONINFOEX {
DWORD dwOSVersionInfoSize;
DWORD dwMajorVersion;
DWORD dwMinorVersion;
DWORD dwBuildNumber;
DWORD dwPlatformId;
TCHAR szCSDVersion[128];
WORD wServicePackMajor;
WORD wServicePackMinor;
WORD wSuiteMask;
BYTE wProductType;
BYTE wReserved;
} OSVERSIONINFOEX, *POSVERSIONINFOEX, *LPOSVERSIONINFOEX;

居然定义的结构不一样！我查了以前的一些帖子，也有人提出这样的问题，但没有解决，还希望各位指点

[mahatma_cn]

因为你的vc6默认的include文件是那个vc6.0自带的，去查查看你的ide中头文件设置里是否有指向你安装的sdk头文件目录。如果没有，编译器就去找那个winbase.h。其实那个结构定义在sdk目录的winnt.h中。
如果你的sdk安装在vc之前，可能要选择整合环境设置。

[shootingstars]

呵呵，你既然安装了VC.net，为什么不直接用VC.net编译？

如果你实在不想使用vc.net，你需要在你的vc6的include目录路径中加入最新的psdk的include目录（应该使用vc.net的include目录也可以。），并且一定保证这个最新的目录在路径的第一个。

to: mahatma_cn(鱼和胸罩不可兼得) ,我根据您的提示在微软网站下载了Core SDK来
更新，安装的时候说系统中已经有相关服务了！我想也应该是啊，因为我已经安装过
.net了，所以应该已经有更新的SDK了！这里有一个不明白的地方是:Platform SDK是
由操作系统的版本来决定的（如果没有更新过的话），还是由开发平台来决定的（如：
VC 6.0和VS.NET),如果是后者，我的系统中，不是有两个版本的SDK（VC6的和.NET的）？
请高手指点！
