ambience,
thankyou for the quick response.
 

 how to get the values from the record set,

In VB it is like this,

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.
