The windows message problem appears only on windows Vista.
So as the Pc are working under XP i don't have the problem.
Invoking Rasdial i get rid of all windows messages which on the contrary appear if i use dialinternet() function.
I also had the problem of trying to call different numbers to check whis is the good one.
I also solved this problem doing nothing :)
Windows Phonebook gives you the opportunity of storing more than one number in a single connection setup and also remember and use as the first one, the last one whiche succeded in connection.
thANK YOU all anyway
