问题 I want to execute JavaScript code by using CefSharp in Windows Forms, but it does not work. The code is as following, and the message test is not shown. Did I miss something? var browser = new ChromiumWebBrowser("http://localhost:50056/simple.aspx"); browser.Name = "Simple Page"; browser.Dock = DockStyle.Fill; this.Controls.Add(browser); browser.ExecuteScriptAsync("alert('test');"); 回答1: You must wait for the browser to have sufficiently loaded before executing JavaScript. It's tempting to

Error when using CefSharp WinForms

由 六眼飞鱼酱① 提交于 2020-01-06 23:44:44
问题 I'm currently using CefSharp in order to embed an Asp.Net website inside a Windows Form. When running on Visual Studio everything works fine, but when I build the application and then I deploy it to the client (User Pc) I get an error that says "Could not load file or assembly 'CefSharp.Core.dll' or one of its dependencies". The main application is built in x86, thus we're using CefSharp in x86. I've updated the .Net Framework, I even copied icutdtl.dat but nothing gets solved. Currently it

由 走远了吗. 提交于 2020-01-06 20:14:55
问题 i need to use web pages on my wpf project and i tried to use wpf web browser control and Chromium CefSharp. my problem is web browser control does not support css transparency and Chromium CefSharp does not support html video tag with mp4 video format. Anyone know of an alternative control? 回答1: You can try with GeckoFx, it's Windows Form Control so you should use a WindowsFormsHost as a container: https://bitbucket.org/geckofx/ 回答2: Cefsharp doesn't support propietary codecs like mp4 and mp3

CefSharp : Html from local resource loading, JS,Images not loading

由 自古美人都是妖i 提交于 2020-01-06 17:58:39
问题 I am working on a CefSharp application in which we are trying to load content locally. It's partially working for me, as it's only loading HTML. Any type of CSS, JS, images are not loaded. I have tried adding multiple paths, even tried directly adding it in the same resources folder, but it doesn't work. What am I doing wrong? Code : namespace OurApp { public partial class OurApp : Form { public ChromiumWebBrowser chromiumBrowser; FileResourceHandlerFactory fileResourceHandlerFactory = new

使用CefSharp在.Net程序中嵌入Chrome浏览器（一）——简介

有的时候，我们需要在程序中嵌入Web浏览器，其实.Net Framework中本身就提供了WebBrowser控件，本身这个是最简单易用的方案，但不知道是什么原因，这个控件在浏览网页的时候有些莫名的卡顿，有的时候甚至能达到好几秒，严重影响体验。 这个时候，我们可以考虑使用第三方浏览器来代替系统的WebBrowser，常见的方案是使用版本帝Chrome，Chrome本身提供了供第三方程序嵌入的方案 Chromium Embedded Framework (CEF) ，但这个是C++的接口，在.Net程序中使用还是有一定的工作量的。不过目前已经有一些开源的项目完成了这一封装，其中的一个佼佼者就是 CefSharp ，WPF和WinForm的封装都实现了，本文就简单的介绍一下如何在WPF程序中使用CefSharp来嵌入Chrome浏览器。 安装： 安装的过程非常简单，只要使用NuGet安装 CefSharp.Wpf 即可。 PM> Install-Package CefSharp.Wpf 安装过程本身比较常规，不过值得一提的是，这个包非常大，由于集成了x86和x64的版本，整个包（加上几个依赖的包）达到了200多mb，基于众所周知的原因，和Nuget的访问一直不大通畅，有时还抽风整个过程非常漫长，一定要有足够的耐心以及人品。 修改编译选项： 由于Chrome是原生程序

CefSharp - Get Value of HTML Element

由 江枫思渺然 提交于 2020-01-02 05:35:09
问题 How can I get the value of an HTML element with CefSharp? I know how to do with this default WebBrowser Control: Dim Elem As HtmlElement = WebBrowser1.Document.GetElementByID("id") But I didn't find anything similar for CefSharp. The main reason I am using CefSharp is because part of the website is using iframes to store the source and default WebBrowser doesn't support it. Also, does CefSharp have an option to InvokeMember or similar call? I'm using the latest release of CefSharp by the way.

C# Winform 运行异常 CefSharp.core.dll 找不到指定的模块

由 谁都会走 提交于 2019-12-27 21:42:48
C# Winform开发中使用了CefSharp，之前在VS2012中运行很正常，今天换了一台Windows XP 打开 VS2010 运行时，发生异常：System.IO.FileNotFoundException；Coloud not load file or assembly ‘CefSharp.core.dll’ or one of its dependencies,找不到指定的模块。 File name:’ CefSharp.Core.dll ‘。 由于XP系统的VS只安装了 C# 开发模块，以为是没有装VC++环境，于是找到 VS2010 的安装包又重新安装了VC++，再次启动 VS2010 运行程序依然报异常。 后来发现必须安装 VC++ 2013 Redist ，这个文件在CefSharp中的Readme.txt文件中有提及，原以为 VS2010 中的C++安装会自带，看来是没有，只能单独安装了。 Visual C++ Redistributable Packages for Visual Studio 2013下载地址：https://www.microsoft.com/zh-cn/download/confirmation.aspx?id=40784 安装 VC++ 2013 Redist 后，程序运行恢复正常。 来源： https://www.cnblogs
