以下是与IE浏览器通信的类,调用系统API,查找窗口,获取IHTMLDocument对象(相当于网页中的document对象),其它操作可通过javascript实现. 添加MSHTML引用

示例代码IHTMLDocument2 doc = Win32API.GetHtmlDocument("IE窗口标题");
doc.parentWindow.execScript("要点击的按钮.click()", "javascript");

Answer 2

你用       WebBrowser            HtmlDocument hb = wb.Document;
            hb.GetElementById();//得到那个按钮然后写事件
处理一下点击，当然还要显示出验证码,手工填写.
           

Answer 3

我就是想知道如何处理点击，楼上的2位讲的还不是很清楚，另外doc.parentWindow.execScript("要点击的按钮.click()", "javascript");
这个 要点击的按钮.click()能这样写吗？按钮没有名字的啊，获得的id也是引用，难道能变成字符串？
