Hi,

Anyone know the code or how to parse through emails that a site gives you and click the links inside of them. Im using the dll OpenPop3 but so far have only figured out how to login.

Any help would be appreciated

  • Just download the emails with the POP3 connection, then you can use the following regex to match all the links.

    #(http|https|ftp)://([A-Z0-9][A-Z0-9_-]*(?:.[A-Z0-9][A-Z0-9_-]*)+):?(d+)?/?#i
  • Can I use OpenPop3 or do I use the built in support for POP3 that C# brings?
  • I checked out OpenPop3 on SourceForge but I don't see any files or examples so I can't tell you for sure. I imagine its just a helper library to communicate with the built in POP3 functions so I don't see why not, try reading the documentation.

    Also, I found another similar library called OpenPop OpenPop.NET | Free Communications software downloads at SourceForge.net which seems to actually have files to download and it says it supports all the common POP3 functions and email MIME types.
  • This is what I have so far:

    Code:
     Pop3Client client = new Pop3Client();
            client.Connect("pop3.live.com", 995, true);
            client.Authenticate("USER", "PASSWORD");
            label18.Text = client.GetMessageCount().ToString();
            int messageCount = client.GetMessageCount();


            for (int i = 1; i <= messageCount; i++)
            {
                // Download the header and check if the message is interesting
                // enough to download if with body
                MessageHeader header = client.GetMessageHeaders(i);
                if ("Wordpress".Contains(header.Subject))
                {
                    // The message is interesting - download it
                    OpenPop.Mime.Message message = client.GetMessage(i);

                    // Find the first part containing HTML
                    // null is returned if such part is not found
                    MessagePart html = message.FindFirstHtmlVersion();
                    if (html != null)
                    {
                        String htmlContained = html.GetBodyAsText();
                        // Do something with the html
                        // here showing it in a listbox
                        richTextBox1.Text = htmlContained;
                    }
                }
            }
            client.Disconnect();

    • You could looks for the characters "<a href", then split the strings up til you find the immediate next "</a>". Then add all those split strings into a generic list.

      Once they're in a generic list you can bind that list to a repeater, and dynamically create them as a page you could click the links on.

      Here's some info on generic lists: An Introduction to C# Generics
  • I know it looks like a bunch of gobbleygook, but you should really use the Regular Expression method that unnatural posted. C# has a great Regular Expression library and there is tons of free sample code out there. You can literally parse ALL LINKS out of an email in 3-4 lines of code.
