关于在Winfrom中获取IE页面按钮事件的问题求教

Question

本人新手，这段时间在做一个后台打印程序，流程是这样的，打开程序 －自动登陆网页－网页上点击“打印”按钮—获取网页表格数据－打印

打印按钮的源码如下

<div class="tbBtn">
                 <input type="image" name="ctl00$CP1$cmdPrint" id="ctl00_CP1_cmdPrint" src="../../Images/Public/plane/print.gif" onclick="return cmdPrint_onclick();" style="border-width:0px;" />
             </div>

现在登陆网页、获取数据，打印的程序都可以用了，就是这个打印按钮事件的事情一直处理不掉，请高手帮忙。

本人用vb.net谢谢

你好：

尝试一下给Document对象注册鼠标点击事件，以下代码可以执行：

private void Form1_Load(object sender, EventArgs e)
        {
            webBrowser1.DocumentCompleted += webBrowser1_DocumentCompleted;
            webBrowser1.Navigate("http://www.microsoft.com");
        }

        private void webBrowser1_DocumentCompleted(Object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            webBrowser1.Document.Body.MouseDown += new HtmlElementEventHandler(Body_MouseDown);
        }

        void Body_MouseDown(Object sender, HtmlElementEventArgs e)
        {
            switch(e.MouseButtonsPressed)
            {
                case MouseButtons.Left:
                    HtmlElement element = webBrowser1.Document.GetElementFromPoint(e.ClientMousePosition);
                    if(element != null)
                    {
                        MessageBox.Show(element.TagName);
                    }
                break;
            }
        }

或者使用这篇文章中的方法，给需要注册点击事件的html元素逐个注册事件：

WebBrowser Element Events and Values

我用的是C#代码，VB.NET代码没有什么差别。

在VB.net中，你的代码

 webBrowser1.DocumentCompleted += webBrowser1_DocumentCompleted;
            webBrowser1.Navigate(http://www.microsoft.com);

不能被支持……
