IsElevated

Is there a simple way to check if my app is running elevated?

 

I can see a few oldish posts on this on Google, but nothing recent. I was just wondering if newer Delphi has introduced a simple function for it, although I couldn't find anything in help or likely units. Or  perhaps there is a new Windows API procedure?

The ones you found probably does something like this, so I guess that's oldish too :classic_rolleyes::

// -----------------------------------------------------------------------------
//
//              RunningAsAdmin
//
// -----------------------------------------------------------------------------
// Detect if we're running at an elevated security level.
// -----------------------------------------------------------------------------
function RunningAsAdmin: boolean;
var
  hToken, hProcess: THandle;
  pTokenInformation: pointer;
  ReturnLength: DWord;
  TokenInformation: TTokenElevation;
begin
  Result := False;
  hProcess := GetCurrentProcess;
  try
    if OpenProcessToken(hProcess, TOKEN_QUERY, hToken) then
      try
        FillChar(TokenInformation, SizeOf(TokenInformation), 0);
        pTokenInformation := @TokenInformation;
        GetTokenInformation(hToken, TokenElevation, pTokenInformation, SizeOf(TokenInformation), ReturnLength);
        Result := (TokenInformation.TokenIsElevated <> 0);
      finally
        CloseHandle(hToken);
      end;
  except
    // Ignore error - although none of the above should throw an exception...
  end;
end;

If you want it to always run elevated, you can specify that in the manifest.

No. I just need to know if user has run my app in elevated mode.  My App launches Outlook and if one is running elevated and the other isn't then you get an OLE error. I just want to be able to advise user which is doing which so they can correct.
