Why is the Webbrowser control DocumentComplete event fired for top level frame first?

由 一笑奈何 提交于 2019-12-07 13:32:06
问题 Based on this article on MSDN: How To Determine When a Page Is Done Loading in WebBrowser Control, and from past discussions on StackOverflow, I would assume that in case of a document with multiple frames, the DocumentComplete event would fire multiple times, and the last time would be for the top level frame. However, using the exact sample code from the above-mentioned MSDN link, I find that if there are multiple DocumentComplete events when doing a Navigate to a URL, the condition is

问题 Is there anyway to call a JavaScript function from .NET Compact Framework through the WebBrowser control? 回答1: It works with the Navigate() Method.

For example: webBrowser1.DocumentText = @"<html><head> <script type='text/javascript'> function doIt() { alert('hello again'); return 'i did it!'; } </script> </head><body>hello!</body></html>"; webBrowser1.Navigate(new Uri("javascript:doIt()")); 来源： https://stackoverflow.com

Save WebBrowser Control Content to HTML

由 烂漫一生 提交于 2019-12-07 09:18:23
问题 I have a WebBrowser Control and have called the Navigate(url) function of it for a given file. Then I have manipulated the DOM tree by giving new Id's to some of the tags. Now I want to save the result in an HTML file. I have tried to use the webBrowser.DocumentStream, but it seems that this stream won't change after manipulating the DOM tree. Please keep in mind that the encoding in WebBrowser.Document.Encoding must be used to encode the result. 回答1: Like this: File.WriteAllText(path,

问题 I am currently hosting an IE Browser control in a .NET (2.0) Form and using it to load Office files such as Excel and Word thusly: _ieCtrl.Navigate("C:\\test.xls", False); The hosting and loading works well except whenever I navigate to a file I am presented with a dialog that asks whether I want to save or open the file. (This is standard IE file-download behavior.) I always want to open it of course and I do not want the dialog to show. Another issue is that when I close the window that

问题 Does Gecko expose an API for working directly with its DOM? I'm looking for a class like HtmlElement that can be used to build/traverse trees of HTML content.

Thanks! 回答1: Yes, virtually all of the classes relating to the DOM are exposed through XPCOM. In fact, I believe the entire functionality of Gecko is exposed this way. 回答2: greyfade: whilst your answer
