请教vc中如何判断操作系统是win9x还是win2000

[xxtliu]

好象用函数GetOSVersion()吧,具体怎么写的记不清楚了,你看一下MSDN吧
对了,好象还有一个宏可以判断,可惜也记不清楚了

Platform SDK: Windows System Information
GetVersion
The GetVersion function returns the current version number of the operating system.

Note This function has been superseded by GetVersionEx. New applications should use GetVersionEx or VerifyVersionInfo.

DWORD GetVersion(VOID);
Parameters
This function has no parameters.

Return Values
If the function succeeds, the return value is a DWORD value that contains the major and minor version numbers of the operating system in the low order word, and information about the operating system platform in the high order word.

For all platforms, the low order word contains the version number of the operating system. The low-order byte of this word specifies the major version number, in hexadecimal notation. The high-order byte specifies the minor version (revision) number, in hexadecimal notation.

To distinguish between operating system platforms, use the high order bit and the low order byte, as shown in the following table:

Platform High-order bit Next 7 bits Low-order byte
Windows NT 3.51 0 Build number 3
Windows NT 4.0 0 Build number 4
Windows 2000 or Whistler 0 Build number 5
Windows 95, Windows 98, or Windows Me 1 Reserved 4
Win32s with Windows 3.1 1 Build number 3


Remarks
The GetVersionEx function was developed because many existing applications err when examining the packed DWORD value returned by GetVersion, transposing the major and minor version numbers. GetVersionEx forces applications to explicitly examine each element of version information. VerifyVersionInfo eliminates further potential for error by comparing the required system version with the current system version for you.

The following code fragment illustrates how to extract information from the GetVersion return value:

dwVersion = GetVersion();

// Get the Windows version.

dwWindowsMajorVersion = (DWORD)(LOBYTE(LOWORD(dwVersion)));
dwWindowsMinorVersion = (DWORD)(HIBYTE(LOWORD(dwVersion)));

// Get the build number.

if (dwVersion < 0x80000000) // Windows NT/2000, Whistler
dwBuild = (DWORD)(HIWORD(dwVersion));
else if (dwWindowsMajorVersion < 4) // Win32s
dwBuild = (DWORD)(HIWORD(dwVersion) & ~0x8000);
else // Windows 95/98/Me
dwBuild = 0;

可以通过Windows API函数GetVersionEx来获得

[qiwei]

GetVersion 与 GetVersionEx 都可以!

[jakieliu]

给分了!

[我不是大明]

yeah!
