I now think there are two ways,The first with a Clipboard. GetDataObject (), but this kind of method, can't get along with all the images and, and unable to get links to content (i.e. source code, htmlText),
The second use EnumWindows -- MSHTML. IHTMLDocument2, but this method can only obtain compatibility mode content, namely InternetExplorer, unable to get Chrorme speed mode?
Please everyone a great god can help me with a maze, refers to the way, thank you!
