Get finished download in CefSharp

阅读更多关于 Get finished download in CefSharp

问题 I try do make a small downloader-tool for a website with CefSharp. For downloading files, I use the pretty well example DownloadHandler from CefSharp. Now, I want to do some things after the download is finished. I know the " downloadItem " has a " IsComplete " value. But if I put something like this in the " OnDownloadUpdated " method, stuff will never be executed if (downloadItem.IsComplete) { //do stuff } So, my question is, where I have to check if my downloaded item is completed? EDIT:

CEFSharp Resource loaded event

阅读更多关于 CEFSharp Resource loaded event

问题 I am looking for something to intercept the response of a resource loaded. For example an image. I am aware the OnResourceResponse method in the CefSharp.IRequestHandler is not available. See this link: https://github.com/cefsharp/CefSharp/blob/master/CefSharp/IRequestHandler.cs#L37 Is there any other way I can intercept a resource loaded? I only need to know if the request is ready, and what URL it contains. I do not mind about the content. 来源： https://stackoverflow.com/questions/26959731

Background process on the native function at Chromium Embedded Framework

阅读更多关于 Background process on the native function at Chromium Embedded Framework

问题 I'm testing a CEF3 program on Visual Studio 2013(C++) and Windows 8.1. I want to process the native function called from JavaScript. However, while the native function is executing, a browser freezes. PostTask is not effective, either. In the case of a thread is made with CreateThread(Win32 API), it occurs an error when getting CefV8Value in the other thread. Isn't there any good way of processing a function asynchronously? CefSettings settings; settings.single_process = true; void App:

阅读更多关于 CEFSharp (Chromium Embedded Framework) in Interop User Control

问题 I am trying to use the CefSharp CLR bindings for the Chromium Embedded Framework to create an alternative web browser control that we can embed into an application that only supports legacy ActiveX controls (WonderWare InTouch HMI) in an attempt to gain some HTML5 support for some reeaaallly old machines. So far, I've created an Interop User Control using the Microsoft InteropForms Toolkit and embedded a CefSharp.WinForms WebView onto the control in a pretty bare-bones manner, i.e. Private

How to restrict CefSharp Browser to given domain

阅读更多关于 How to restrict CefSharp Browser to given domain

问题 I would like to prevent my application to display web pages other than from a certain domain (i.e. example.com). My initial idea was to check the request URL in the OnBeforeBrowse event handler. public bool OnBeforeBrowse(IWebBrowser browser, IRequest request, bool isRedirect) { return !IsPageAllowed(request.Url); } This looks doable, except for the fact that all embedded resources on a allowed page are also triggering this event. For example, i have a YouTube video embedded on my page there

CEF3 single process mode in production

阅读更多关于 CEF3 single process mode in production

问题 Are there any real pitfalls in using single process mode in production? The official statement seems to discourage this, but so far the application has been stable. CEF1 seems to have been abandoned, and if CEF3 single process is used for dev, then the latter should be at the very least be part of the test suite, and therefore stable. Or is that not true? Also, is CEF3 single process not equivalent to CEF1? The new Battle.net launcher is using CEFl (1453). I wonder if that was for legacy

CefSharp Accessing Encrypted HTML/JS/CSS Files

阅读更多关于 CefSharp Accessing Encrypted HTML/JS/CSS Files

问题 I have been building a Windows desktop application in WPF and it has an embedded browser (CefSharp) that load local HTML/JS/CSS files. These files do not come readily with the application. They will be downloaded from a server each time the program is started. These files are kept in user's application data folder. My concern is that these files, although hidden in the application data folder, user could still find them, open them and read their content. These files actually play the biggest

问题 I am using CefSharp v55.0 in my WinForm project. After the page is loaded, I want to get HTML code from it. And for that I am using this: private void WebBrowserFrameLoadEnded(object sender, FrameLoadEndEventArgs e) { if (e.Frame.IsMain) { test.ViewSource(); test.GetSourceAsync().ContinueWith(code => { var html = code.Result; }); } } And for the crosscheck, I am also calling test.ViewSource() method, to see that if GetSourceAsync method is getting the whole code or not. Unfortunetely, codes
