在MSN 6 以后，对话框中已经不使EDIT控件了 用Spy++看看，已经不对了。 解决方法两种： MSN 提供了API 用法和COM一样，所以可以使用，我已经证实可以使用在5.0--6.0以上的版本 但是好像不在提供下载了 如果你用过VB，可以在引用中看到 VC的方法类似 再有就是需要钩子技术了，但是很复杂。 As you may know, MSN Messenger before 5.0 (inclusive) uses a "RichEdit" common control as the chat input area and chat contents area, the "Send" button is a genuine "BUTTON" windows control. To interact with it, your program uses a hook or whatever remote injection ways to penetrate into MSN Messenger process space, and conduct button-pushing and text-reading just the same as doing this in a dialog-based GUI program we all have been writing. But, in MSN Messenger 6.0, when you use SPY++ to check its windows layout, there is only a "DirectUIHWND" window. "DirectUIHWND" is a widely used wrapper windows class since the emergence of Windows XP, according to my observation. If you are using WinXP/2003, you can modify Mr. Keith Brown's tool CmdRunAs in Feb 2000, MSJ or Mr. Martyn 'Ginner' Brown's tool Start a Command As Any User in www.codeguru.com 2001, or if you are a lazy typist, use my GUI-based "RunAs" directly to launch SPY++ under "LocalSystem" account to your logon desktop(WinSta0\Winlogon). 我也在开发这方面的东西，基本完成了功能，欢迎探讨

他使用COM与text services object进行交互,所以,要得到数据就必须截获msn到text services object的函数调用.
www.codeproject.com上有一篇介绍hook com interface的文章

什么功能都有了(我这里有一个,可以传给你)
看来目前方法有两个，
一是用msn提供的API，结合抓获句柄来实现
二是用hook技术，具体如何实现还得查资料啊，还有谁可以补充得吗？没有得话，我就揭帖了。
再次感谢！
