IsElevated

[Mark Williams 15]

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 :

// -----------------------------------------------------------------------------
//
//              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.

RunElevatedSupport.pas is what I use.

Call IsElevated (Boolean) thats all you need to do.

Also offers to elevate code pieces.

 

I love it.

You might love the ease of use aswell.

Never had any kind of problems so far.

 

Only limitation is when you execute elevated code. That depend on your code. To write files or registry data it worked flawless for me so far.

 

Enjoy it 🙂
