Publish source code, new programs, analyze Web pages, take specified values, store, manipulate web pages, fill in values, simulate clicks, fault tolerance, and send.

To add more people in the circle of friends, I wrote this program, extracted the usernames in the member list, wrote them to dataview, and filled them in the textbox. The program automatically clicked "invite ". Webbrowser is used to analyze HTML and operate some controls on the webpage, such as clicking and buttons. Enter the content.

There are not many codes, so I can understand it at a glance and won't write more.

 

The source code is as follows:

 

Using System;
Using System. IO;
Using System. Net;
Using System. Collections. Generic;
Using System. ComponentModel;
Using System. Data;
Using System. Drawing;
Using System. Text;
Using System. Windows. Forms;
