I am testing the connection string by opening it and then closing the connection which has been assigned the function of testing. The problem comes in when u open the connection and the server is not there. It stalls the whole system for 30 seconds (Default Time out). Try _conn.ConnectionString = ReconfigConnString() I am looking for an idea where the system can test the connection AND do the other functions that needs to be complete before the form close. In multi threading the connection thread will over power the other threads and will cause one of two things. Deadlocks or either full system stalling until time out.:cool: System complete...bug free? I'll find a bug. :zzz:
