由 白昼怎懂夜的黑 提交于 2019-11-26 11:35:28
问题 I have a WebBrowser control in WinForms whose URL property is set to an external webpage. I also have an event handler for the DocumentCompleted event. Inside this handler, I\'m trying to get specific elements, but wb.Document.Body seems to capture the HTML before onload is executed. {System.Windows.Forms.HtmlElement} All: {System.Windows.Forms.HtmlElementCollection} CanHaveChildren: true Children: {System.Windows.Forms.HtmlElementCollection} ClientRectangle: {X = 0 Y = 0 Width = 1200 Height

Calling a Javascript function in the C# webBrowser control

由 被刻印的时光 ゝ 提交于 2019-11-26 11:21:02
问题 I am using the webBrowser control in C# to load a webpage and need to call a JavaScript function that returns a string value. I got a solution to use the InvokeScript method, and I tried a lot, but everything has failed. 回答1: Can you specify what failed? My sample below consists of a form with a WebBrowser and a Button. The object called y in the end has the sentence "i did it!". So with me it works. public partial class Form1 : Form { public Form1() { InitializeComponent(); webBrowser1

问题 Using VS2013 I created a very simple web browser Control application that navigates to http://demos.dojotoolkit.org/demos/calendar/demo.html When no FEATURE_BROWSER_EMULATION is set for this application in the registry the site functions correctly, When adding the application to this registry key (under HKLM) it is working till IE9 emulation but fails with IE10 and IE11 values (i have IE11 on my machine). example: FEATURE_BROWSER_EMULATION myApp=9999 - works myApp=10001 - doesn\'t work doesn\

Webbrowser Control Limitations

由 眉间皱痕 提交于 2019-11-26 11:19:08
问题 I am using the WebBrowser control in a windows form C# project and wanted to know if there are any limitations of how many instances of such application you can have running at the same time. (in other words does MSFT enforce any limitations other than physical machine limits - CPU/memory etc) 回答1: There are no artificial limitations on the WebBrowser control. However, it uses IE's rendering engine (whatever version is installed on the end-user's computer), so it uses a fair bit of memory.

Implement IDispatch::Invoke to be called by a WebBrowser control

问题 I\'m trying to do what they explain on this article in the Controlling Download and Execution section. I understand the Web Browser Control in that context is not .NET\'s WebBrowser . What I\'m trying to do is to gain control over what the WebBrowser control downloads. I\'ve been searching for this a lot and always en up in the csEXWB , which has a huge code that I just cannot decipher. What I\'ve done so far is inherit .NET\'s WebBrowser , make my inherited class com visible by using the

Use cookies from CookieContainer in WebBrowser

由 亡梦爱人 提交于 2019-11-26 11:04:19
问题 Is there any way that I can actually use the cookies from a cookie container (taken from a WebRequest previously) and use them in a WebBrowser control? If so, how would I do this? This is for a Winforms application in C#. 回答1: You need to make use of InternetSetCookie. Here is a sample... public partial class WebBrowserControl : Form { private String url; [DllImport("wininet.dll", CharSet = CharSet.Auto, SetLastError = true)] public static extern bool InternetSetCookie(string lpszUrlName,

Zoom in on a web page using WebBrowser .NET control

由 你离开我真会死。 提交于 2019-11-26 10:59:01
问题 In IE7 there\'s a \"zoom\" feature built-in (show in the status bar), allowing you to zoom in up to 400%. I\'m using the WebBrowser .NET control in a demo/simulation app, and need to zoom in on a web page. Is this at all possible? (I don\'t want to simply take a picture of the page and enlarge it, as I need to use the links and buttons on the page). I\'m using .NET 2.0 if it matters. 回答1: There appears to be a solution at IE Zoom that involves overriding AttachInterfaces and DetachInterfaces

Use local images in Webbrowser control

由 自古美人都是妖i 提交于 2019-11-26 10:03:13
问题 I\'m using a Webbrowser Control in my Wp7 app, but I can\'t seem to put images that are in the App directory, in the webbrowser. I\'ve put some images in a folder in the same directory as the .cs and .xaml files. Now I try to put them in the webbrowser control, but I can\'t seem to get this to work. <img src=\"images/photo.jpg\"/> <img src=\"/images/photo.jpg\"/> The two above obviously don\'t work, my guess is that it should be something like this: <img src=\"/SilverlightApplication

Is there a possibility to address elements on a website which have no ID?

由 感情迁移 提交于 2019-11-26 10:02:50
问题 In Vb.net, with a Webbrowser, I normally use GetElementById to address for example a button. I know that there is GetElementFromPoint , which I find extremly laborious. Is there a better, simpler way when the ID is unknown? 回答1: You will need to use some type of selector. The GetElementByID method works best because if the HTML file is formatted correctly then there should only be one element with that unique ID. The GetElementFromPoint will return an element based on the X,Y coordinate of
