1 This applet can now crawl in the Web address field to enter the URL and crawl this page some QQ number.

Now to introduce its principle, in the Web address bar to enter the destination URL, click to grab the mailbox to request the Web page source code and through the written regular expression to traverse the matching mailbox address and through a for loop written to the lower textbox.

2 by crawling has already shown the email address in the right text box, click the mouse to select the email address you want to add (can choose multiple), click the Add button to display the recipient text box by the assignment (if single, select one, mass please select more than one).

When you click the "Add Recipient" button: Add the Web page to fetch the email address;

When you click the Add button: Add the email address entered in the Enter recipient address bar.

3 Click the "Add Attachment" button to send the selected file as a message attachment.

Filter out the file type by Openfiledialog1.filter and open the dialog box, define the variable to receive the Open dialog box, OK after defining a variable to receive the file path, and create a stream to convert the file path.

4 First enter the sender's e-mail address and password (in order to prevent the sending of spam, the general use of enterprise mailbox as the sending address, and in the mass when the processing of delayed delivery).

Click on the "Send button" will be based on the number of recipient address automatic single or mass (the recipient address is one time, for multiple when the mass), if the successful send prompt "send success", otherwise you will be prompted to get the error message.

Defines the mailbox transport protocol class, determines the port number of the mailbox server and server SMTP, determines how the send is sent to the SMTP server for the network, establishes the e-mail class, confirms the encoding, determines and sends.
