sending email

What is the problem that you are facing?

When user get email  and click the link it is open in new tab without lblcode.text

So for that you need to place breakpoint where body is populated and check whether lblcode has value

get the mail in this form

 http://localhost:49509/point/activate.aspx?code= e185f

i want =e185f is also hyperlink.

use following

mm.Body ="Thanks for the Registration. To acctivate your account Please visit the link http://localhost:49509/point/activate.aspx?code="+ lblcode.Text
