This article demonstrates how to programmatically save to disk an HTML page that has been loaded into Internet Explorer without prompting the user.
As a Web browser control host, or an application that is automating Internet Explorer, you may find it useful to be able to programmatically save the currently loaded document to disk without user intervention. The following code samples illustrate how to accomplish this in both Visual C++ and Visual Basic. While the Visual Basic solution also works in Visual C++, you cannot implement the Visual C++ solution in Visual Basic.
Visual Basic SolutionYou can use the Internet Explorer Document Object Model to capture all of the HTML sources into a string variable. The string variable can then be written out to a text file and saved to disk.
Visual C++ SolutionAccomplishing this task from a Visual C++ host is very straightforward. You can use an IWebBrowser2 interface to call the QueryInterface method for the IHTMLDocument2 interface. After you obtain a pointer to the document, then call QueryInterface for the IPersistFile interface. After you obtain this interface pointer, you can call the save method to save the file to disk.
