紧急通知:本站老域名全部失效，请用户记下新域名访问本站，拿笔记好。这篇文章中我们介绍了SWT中通过Automation访问IE的方式，但是只是简单的URL导航，没有自动填表单、自动提交等功能。我们对其进行了升级，采用了新的操作方式，充分利用了SWT对OLE的支持，裁减掉大量代码。现在可以实现自动填表单、自动提交等功能。不过暂时还无法响应IE的事件。
核心代码如下：

import org.eclipse.swt.internal.;
import org.eclipse.swt.internal.ole.win32.GUID;
import org.eclipse.swt.internal.ole.win32.IU
import org.eclipse.swt.ole.win32.OLE;

&&//等待加载完毕，正确的方式应该是在网页onComplete的时候继续执行，但是没弄明白OLE 的EventSink机制怎么搞到SWT中来

写得很好，不过我调试了，怎么有些问题，楼主能否把 源码发一份给我， 调试看看效果。 非常感谢

&re: SWT中通过Automatioin的方式访问IE（升级版）
科哥, 你的例子很好,但是请问一下怎样知道一个IE平时发出哪些事件,在哪里有得查,
client.addListener(new Listener()
public void handleEvent(Event event)
System.out.println(event.type);
System.out.println();
发出来的Type,有没有手册可以查
