Simon,

>Does anybody know how I can return a logical value from a command to see if the currently logged on user has full adminstration rights, i.e. to install a printer (PDF) from my application. I know you can detect this type of thing, but haven't come across any command to do this?

I've found the following code in another forum. I haven't tested it and I haven't looked through it, to see if this is going to do exactly what you need. But maybe it helps.

#define ADS_SECURE_AUTHENTICATION 1 
 
LOCAL loAd,loProvider,loWinNT,loUser,loGroup 
 
loAd = GETOBJECT("ADs:") 
FOR EACH loProvider IN loAd 
  IF loProvider.Name == "WinNT:" 
    loWinNT = loProvider 
    EXIT 
  ENDIF 
ENDFOR 
loUser = loWinNT.OpenDSObject("WinNT://"+ALLTRIM(STRTRAN(SYS(0)," # ","/")),"Administrator","",ADS_SECURE_AUTHENTICATION) 
FOR EACH loGroup IN loUser.Groups 
  ? loGroup.Name
