I am new to ASP.NET (only coded web pages in HTML in the past), and I'm
having some trouble: I have a form on which a visitor to my page can
fill out comments and send them to my E-mail box. The code works fine
when I test it on my local machine; but for the identical code deployed
to my web site (hosted on GoDaddy.com), when I click the "Submit" button
to send the E-mail, an exception is thrown containing the following
error:
Request for the permission of type 'System.Net.Mail.SmtpPermission,
System, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089' failed.
I don't have the slightest idea when this means. I'm using the Express
version of VS 2008, so I cannot remotely debug the code. Does anyone
have any idea what's wrong? Here are the relevant code snippets:
Contact.aspx
