Dear Jimmy,

Not in FWH yet (included for next build). Two distinct things:

Is admin = user belongs to Administrators group
Is elevated = process token currently has admin rights (UAC split token)

Most apps want elevated. Cleanest: GetTokenInformation with TokenElevation (Vista+).

Quick PRG check using shell32.IsUserAnAdmin (deprecated but works XP→Win11):

Code: Select all Collapse

  DLL32 FUNCTION IsUserAnAdmin() AS BOOL PASCAL FROM "IsUserAnAdmin" LIB "shell32.dll"

  function Main()
     if IsUserAnAdmin()
        MsgInfo( "Running elevated" )
     else
        MsgInfo( "Not elevated" )
     endif
  return nil

Proper way (TokenElevation, Vista+, no deprecation): C helper.

Code: Select all Collapse

  #include <hbapi.h>
  #include <windows.h>

  HB_FUNC( ISELEVATED )
  {
     HANDLE hToken = NULL;
     TOKEN_ELEVATION te;
     DWORD dwSize = 0;
     BOOL bElevated = FALSE;

 if( OpenProcessToken( GetCurrentProcess(), TOKEN_QUERY, &hToken ) )
 {
    if( GetTokenInformation( hToken, TokenElevation, &te, sizeof( te ), &dwSize ) )
       bElevated = te.TokenIsElevated;
    CloseHandle( hToken );
 }
 hb_retl( bElevated );
  }

Run elevated programmatically if user clicks "run as admin" button:

ShellExecute( 0, "runas", "myapp.exe", "", "", 1 ) // UAC prompt
