利用WebBorwser和MSHTML.tlb做广告过滤器完全源码公开
程序组成:
两个引用对象:Microsoft HTML Object Library,Microsoft Internet Object
两个窗体: frmAbout.frm frmMenu.frm
两个*.bas: APIs.bas,mSysTray.bas
两个Class: MyIE.cls, windows.cls(其中windows.cls是collection对象的扩展,放MyIE.cls)
下面公开这两个主要类的代码(如要全部代码请留email,要看演示上www.jjsoft.cn,版权归作者,要用于商业目的请和作者联系fazhu@163.net)
