mshtml

问题 I faced that simply iterating through MSHTML elements using C# is horribly slow. Here is small example of iteration through document.all collection three times. We have blank WPF application and WebBrowser control named Browser: public partial class MainWindow { public MainWindow() { InitializeComponent(); Browser.LoadCompleted += DocumentLoaded; Browser.Navigate("http://google.com"); } private IHTMLElementCollection _items; private void DocumentLoaded(object sender, NavigationEventArgs e) {

问题 I've been looking hard for this but still have not found any solution. I'm using native win32 c++ (no MFC, ATL or .NET) I'm loading an html document with IHTMLDocument2->write().

问题 I saw a lot of examples in MSDN on how to use MSHTML in VS. Have anyone known if and how we can use MSHTML and VBA to open web pages?

问题 I am using slightly modified IDocHostUIHandler from https://stackoverflow.com/a/21699086/592212 in simple one main window test application with only WPF WebBrowser component in that Window. The initialization code is as follows: public MainWindow() { InitializeComponent(); _wbHostHandler = new WebBrowserHostUIHandler(PART_WebBrowser); _wbHostHandler.Flags |= HostUIFlags.DpiAware; PART_WebBrowser.Navigate("SOME_URL"); } There is really nothing else going on in the Application. Still, after

问题 Using the .NET WebBrowser control, it is fairly simple to execute a member of an HtmlElement. Assuming there is a JavaScript object called "player" with a member called "getLastSongPlayed"; calling this from the .NET WebBrowser control would go something like this: HtmlElement elem = webBrowser1.Document.getElementById("player"); elem.InvokeMember("getLastSongPlayed"); Now my question is: How do I accomplish that using mshtml ? Thanks in advance, Aldin EDIT: I got it up and running, see my

问题 I am planning to develop web crawler, which would extract coordinates of html elements from web pages. I have found out that it is possible to get html element coordinates by using "mshtml" assembly. Right now I would like to know if it is possible and how to get only necessary information (html,css) from web page, and then by using appropriate mshtml classes get correct coordinates of all html elements? Thank you! 回答1: I use these c# functions to determine element positions. You need to pass
