我一直在使用这样的代码成功地为年内执行单点登录,以提示用户输入其用户名/密码/域的应用程序。唯一要注意的是你需要知道你所针对的对话框的控制结构,但这很容易用Spy ++完成,而且很少改变。当然,你需要修改这个代码来控制窗口的控制结构。

您是否考虑过使用UI自动化框架(如White)来隐藏处理Windows消息的复杂性? (http://code.google.com/p/white-project/)你可以在这里找到一个例子:http://scip.be/index.php?Page=ArticlesNET19&Lang=NL –
我try.I得到例外。尝试投射时无法从Castle.Proxies.Win32ComboBoxProxy投射。 –
