You need to use a Transactionscope[^]

VB

try
 using Trans as new transactionScope()
  'Do database work here

  Trans.commit()
 end using
catch ex as TransactionAbortedException
 messagebox.show ex.message
end catch

queries are not commited to the database until the commit is called. If an error is trapped then the queries are rolled back.
