Send user Confirmation email after Registration.

Question

Hello everyone,

 

I am trying to implement Email confirmation after user registration. Then, I can find the answer from this link http://www.aspsnippets.com/Articles/Send-user-Confirmation-email-after-Registration-with-Activation-Link-in-ASPNet.aspx

 

After using this code, I got an error  

Unable to read data from the transport connection: net_io_connectionclosed.

How can I solve this? 

Please help me.

 

Advance thanks.
