在使用别人的程序时，我们常发现一些好的功能，想通过自己的程序来重复调用。可偏偏这个程序没有留可编程接口，无法通过API、DLL、COM等方式实现调用。早些年与同仁们讨论时，常对此深表遗憾。最近，通过研究Windows API的使用方法，终于从理论上解决了这一问题，即可通WinAPI中SendMessage、EnumChildWindows等，从模拟操作的角度来调用指定程序的指定功能。
使用这种方法，我写个程序多开器，主要实现启动多个实例，能给EDIT框付值，能定时调用其中按钮。
In the use of someone else s program, we often find some good features, would like to adopt its own procedures to repeat the call. Unfortunately, this procedure can not stay in the programmable interface, not through the API, DLL, COM, etc. call realize. Early years of discussions with colleagues, and often regret this very much. Recently, by studying the use of Windows API methods, and finally from the theory solves this problem, you can pass WinAPI of SendMessage, EnumChildWindows and so on, from the perspective of simulation calls the specified procedure designated function. Using this method, I write a program to open, and the main start multiple instances, can EDIT box to pay the value of which can regularly call button. (2008-04-14, C#, 11KB, 下载32次)
