Removing HtmlElement objects programmatically using C#

人盡茶涼 提交于 2019-12-04 06:11:58
In a WebBrowser control, how do I remove HtmlElement objects? There are no methods in the HtmlElement class to accomplish this. As a workaround, I can create a "dummy" HtmlElement (without inserting it into the HtmlDocument ), into which I then insert (via AppendChild ) the HtmlElement objects to be removed. This feels like a hack. Is there a better way to do this? P.S. I want to retain the HtmlElement in memory to be used later, not simply destroy it (which is what setting its parent's innerHtml to an empty string would do) Look at this WebControl Heritance, with loads of feature: http://www

WebBrowser and javascript

断了今生、忘了曾经 提交于 2019-12-04 05:18:41
问题 I am working with a website that has javascript that does some changes on the page load. However, when I load the page and handle the DocumentCompleted event, this change isn't there. If I then continue paste the DocumentCompleted event, I can see the change happen. However I need this change to happen during DocumentCompleted so I can check some things. Is there an other event I can subscribe to, or a way to cause the webBrowser to do all the javscript on page? Edit: This is what I am

问题 I have a loop that goes through a number of values. With every value iterated, a page is loaded in a webbrowser control (with the value passed as a parameter) and when the page is loaded and read, the loop should go to the next value in the list and continue until all values are processed. I need a way to pause the procedure while the website is loading asynchronously and then resume once the page loading/reading process is complete. The way I am doing is by using something like this, where

℡╲_俬逩灬. 提交于 2019-12-04 04:07:50
问题 Is there a class/API in .NET 4.5+ allowing to expose an instance of C# anonymous class as as late-bound object to COM? E.g. I want do this: webBrowser.Document.InvokeScript("TestMethod", new object[] { new { helloProperty = "Hello!", byeProperty = "Bye!" } }); and use it in JavaScript: function TestMethod(obj) { alert(obj.helloProperty + ", " + obj.byeProperty); } It should not be a problem to create a helper class to wrap the anonymous object and expose its properties via IReflect, but
