说明：  VB代码与WebBrowser控制中的HTML代码，互相控制的例子。 点VB中的按钮，改变网页的显示样式或内容。点网页中的按钮，修改VB中控件的属性，或调用VB中的函数。这只是一个如何实现的示例，没有什么强大功能，代码有中文说明。
(VB code and WebBrowser control HTML code, mutual control example. Click the button in VB to change the display style or content of the web page. Click the button in the web page to modify the properties of the control in VB, or call the function in VB. This is just an example of how to implement it. There is no powerful function, and the code has Chinese instructions.)
