I know how to handle database .......
my problem is that when the connection is not success then my class file should be display appropriate message...........so i would like to know the different exception in open() function .........

No one knows all the exceptions, the best will be to inherit the exception class. But at will also be a waste you can just try/catch/finally the connection and all the exceptions will be caught.

-----so i would like to know the different exception in open() function .........

System.InvalidOperationExecption
System.Data.SqlClient.SqlException
System.ArgumentException
