You could try creating it in a TRY/CATCH

TRY
   loTest=CREATEOBJECT("idauto.barcode")
   llRegistered=.T.
CATCH
   llRegistered=.F.
ENDTRY
IF not llRegistered
   .....
ENDIF

It is generally advised not to use general fields. But since I don't know what idauto.barcode does, it is not possible to comment if a general field is the best way to go about it or not. If possible, try to find an alternative to the general field, otherwise always perform the above test before using it.
