我是个新手菜鸟，请大神位，帮教导一下。

    设计了一个简单的浏览器，使用WebBrowse 控件的 event 对象，可以捕获 WebBrowser 众多的鼠标和键盘事件，如鼠标坐标、按下了键盘哪个键，以及键盘 Ctrl、Alt、Shift 键的状态、当前网页元素的ID、索引等等。接收到的 WebBrowse 事件最终汇集到 Form1 的 PageEvents 过程中，修改此过程代码，可以获取不同的页面信息。如果将 Cancel 设置为 True，可以拦截页面某些事件，如 Click、DblClick、KeyPress，可实现到禁止网页跳转、禁止输入等功能。
实现的功能：
　　一.自动将浏览过的网页地址添加到地址栏列表框中
　　二.按下 Alt 键在页面中单击，可将鼠标处的网页元素、鼠标位置等信息复制到剪贴板中。
　　三.在“转到”按钮上单击鼠标左键：跳转到指定网站。 单击右键：显示或隐藏内嵌网页列表
　　四.单击内嵌网页列表某条目，可用新窗口打开这个内嵌网页。
　　五.单击窗口下面的状态栏文字上单击，可切换信息显示方式：详细信息或简单信息。
缺点：
    1、打开如PHP内链接。显示空白页。不知为什么？
    可以调试通过，包含两个窗体：Form1 和 Form2，一个模块：Module1
' ' '在“工程/部件”对话框中勾选：Microsoft Internet Controls
' ' '在“工程/引用”对话框中勾选：Microsoft HTML Object Library
'然后在窗体放置 5 个控件：WebBrowser1、Label1、Command1、Combo1、Combo2
