本文讨论如何对外部程序进行控制，实现操作自动化的各种方法。在实际工作中，经常会遇到需要对现有的其它人编写好的程序窗口中的文本框、按钮等各种控件进行输入、点击等控制，从而实现操作自动化。由于这类程序是由别人编写的，自己没有原程序，无法通过修改程序，实现对程序的控制，所以我们只能另想办法。在现实中，可以把程序窗口分成两类，一类是标准的windows窗口，另外一类是网页式窗口，对于这两类窗口中的控件，其控制方法是不同的，下面分别进行介绍。-In this paper, we discuss how to control the external program and realize the automation of the operation. In the practical work, we often encounter the need for the other people to write the program window in the text box, buttons and other controls to input, click control, so as to realize the automation of the operation. Because this kind of program is written by others, they do not have the original program, can not modify the program to achieve the control of the program, so we can only think of another way. In reality, the program window is divided into two categories, one is the standard Windows window, another kind is the　window, for these two types of window controls, the control method is different, the following were introduced.
