由 青春壹個敷衍的年華 提交于 2019-11-27 16:33:18
问题 I would like to create a .NET application that utilizes multiple instances of the WebBrowser control. The catch is that I'd like each web browser control to be running it's own session. IOW, I have a requirement that the collection of session cookies, javascript global namespace, etc. is separate for each instance and that all instances appear within the same window. AFAIK, this is going to require me to run each web browser control in a separate process. A few questions: Is my assumption

问题 This question already has an answer here: How to inject Javascript in WebBrowser control? 15 answers I want to apply some styling commands to specific website inside WebBrowser control. The best way to do it is to invoke javascript (I want that style to be editable, with javascript it's easy). I know I can do it with webBrowser1.Navigate("javascript: alert('hi'); void(0);"); but maximum url length that webBrowser accepts is 502. How to execute longer scripts? Or maybe there is a way to append

How do I get a C# WebBrowser control to show jpeg files (raw)?

由 时间秒杀一切 提交于 2019-11-27 14:53:15
Does anyone know in .Net 2.0 - .Net 3.5 how to load a jpeg into a System.Windows.Forms.WebControl as a byte-array and with the right mimetypes set so it will show? Something like: webBrowser1.DocumentStream = new MemoryStream(File.ReadAllBytes("mypic.jpg")); webBrowser1.DocumentType = "application/jpeg"; The webBrowser1.DocumentType seems to be read only, so I do not know how to do this. In general I want to be able to load any kind of filesource with a mimetype defined into the browser to show it. Solutions with writing temp files are not good ones. Currently I have solved it with having a

Interaction between WebBrowser Control and Windows Forms

I am managing various contact information - phone, address, email, IM, other and I want it to look good and save real estate, so I want to display it in a WebBrowser control. I can create the markup and content dynamically into a stream and display it with any format with colors and font size easily adjusted. I can also put buttons <input> for Add, Edit, and Delete. I like this method, because it seems easier and better looking than a RichTextBox (correct me if you think otherwise.) The question is about responding to those buttons. If one is selected, I want to hide the WebBrowser and unhide

WebBrowser control and JavaScript errors

由 断了今生、忘了曾经 提交于 2019-11-27 13:35:52
When I access the page with the browser (ie9), the browser is rendering ok. When I use the WebBrowser control I have JavaScript errors. I know I can suppress the scripts errors, but I want them to run correctly, because they affect the rendering and the functionality of the page. How can I solve this problem ? Can I integrate IE9 directly in the Windows Form and use similar methods like with the WebBrowser control (navigate,get id, invoke click) ? Thanks. What I would do is assign an object to webbrowser.ObjectForScripting and then inject a javascript function that assigns windown.onerror to a
