如何判断当前登录用户是否属于Adminitrators组，也就是判断其是否有管理员的权限？

【判断是否为超级用户】
function IsAdmin: Boolean;
var
hAccessToken: THandle;
ptgGroups: PTokenGroups;
dwInfoBufferSize: DWORD;
psidAdministrators: PSID;
x: Integer;
bSuccess: BOOL;
begin
Result := False;
bSuccess := OpenThreadToken(GetCurrentThread, TOKEN_QUERY, True,
hAccessToken);
if not bSuccess then
begin
if GetLastError = ERROR_NO_TOKEN then
bSuccess := OpenProcessToken(GetCurrentProcess, TOKEN_QUERY,
hAccessToken);
end;
if bSuccess then
begin
GetMem(ptgGroups, 1024);
bSuccess := GetTokenInformation(hAccessToken, TokenGroups,
ptgGroups, 1024, dwInfoBufferSize);
CloseHandle(hAccessToken);
if bSuccess then
begin
AllocateAndInitializeSid(SECURITY_NT_AUTHORITY, 2,
SECURITY_BUILTIN_DOMAIN_RID, DOMAIN_ALIAS_RID_ADMINS,
0, 0, 0, 0, 0, 0, psidAdministrators);
{$R-}
for x := 0 to ptgGroups.GroupCount - 1 do
if EqualSid(psidAdministrators, ptgGroups.Groups[x].Sid) then
begin
Result := True;
Break;
end;
{$R+}
FreeSid(psidAdministrators);
end;
FreeMem(ptgGroups);
end;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
if isAdmin then
begin
ShowMessage('Logged in as Administrator');
end;

再小声问一句
编译时显示“SECURITY_NT_AUTHORITY”等未定义，好象是在Winnt.h中定义的，在Delphi中应该如何处理？uses哪个文件？

《Kingron's超级猛料》 中有的

你的第二个问题
--------------------------
const
SECURITY_BUILTIN_DOMAIN_RID = $20;
DOMAIN_ALIAS_RID_ADMINS = $220;
SECURITY_NT_AUTHORITY:TSIDIDENTIFIERAUTHORITY=(Value:(0,0,0,0,0,5));

不能沉了，在线等待

看看用IS能不能有所帮助！

谢谢各位，问题已很好解决！
