thnx david,

didn't know spt means sql pass through.

we do error handling afther 'spt' but the program doesn't seems to bug. Only the next time the user restarts the program than he gets the 'Appel non valide émis lors de l'exécution d'une séquence SQLMORERESULTS()' (french os). When i open the database and i check the connection settings then they are changed. And nowhere in the program we change these settings... AND this happends only with win98 os, the others like xp are working well.
