取得 WinNT/2000 下的用户名

取得 WinNT/2000 下的用户名

// 取得当前用户的 TokenHANDLE hToken = NULL;OpenProcessToken(GetCurrentProcess(), TOKEN_QUERY, &hToken);// 获取 Token InformationDWORD dwReturned = 0;GetTokenInformation(hToken, TokenOwner, NULL, 0, &dwReturned);LPVOID pvOwner = new BYTE[dwReturned];GetTokenInformation(hToken, TokenOwner, pvOwner, dwReturned, &dwReturned);PTOKEN_OWNER pTokenOwner = (PTOKEN_OWNER)pvOwner;// 查找 Token 对应的用户名SID_NAME_USE snu;TCHAR tszName[256], tszDomain[256];DWORD cbName = 256, cbDomain = 256;LookupAccountSid(NULL/* Local system */,     pTokenOwner->Owner, tszName, &cbName, tszDomain, &cbDomain, &snu))// 输出用户名和 Domaincout << _T("User = ") << tszName << endl;cout << _T("Domain = ") << tszDomain << endl;delete[] pvOwner;

取 Groups 和比较是否为 Administrators

// 获取 Token InformationGetTokenInformation(hToken, TokenGroups, NULL, 0, &dwReturned);LPVOID pvGroups = new BYTE[dwReturned];  GetTokenInformation(hToken, TokenGroups, pvGroups, dwReturned, &dwReturned);PTOKEN_GROUPS pTokenGroups = (PTOKEN_GROUPS)pvGroups;// 获取 Administrators 的 SIDPSID pSIDAdmin = NULL;SID_IDENTIFIER_AUTHORITY SIDAuth = SECURITY_NT_AUTHORITY;AllocateAndInitializeSid(&SIDAuth, 2, SECURITY_BUILTIN_DOMAIN_RID,     DOMAIN_ALIAS_RID_ADMINS, 0, 0, 0, 0, 0, 0, &pSIDAdmin);// 查找 Token 是否属于 Administrators 组SID_NAME_USE snu;TCHAR tszName[256], tszDomain[256];DWORD cbName = 256, cbDomain = 256;for (int i = 0; i < pTokenGroups->GroupCount; i ++){    LookupAccountSid(NULL/* Local system */,         pTokenGroups->Groups[i].Sid, tszName, &cbName, tszDomain, &cbDomain, &snu);    if (EqualSid(pSIDAdmin, pTokenGroups->Groups[i].Sid))        cout << " Administrators:" << endl;    cout << _T("Group = ") << tszName << endl;    cout << _T("Domain = ") << tszDomain << endl;}FreeSid(pSIDAdmin);delete[] pvGroups;

上述代码在 Windows 2000/XP 下测试通过。
