WebBrowser control as User Interface

阅读更多关于 WebBrowser control as User Interface

问题 First a few definitions to keep things clear. User: A live person, using the software Client: A company that is paying for a customized version of our software for their users. We currently have a few applications that are going to require significant changes in the user interface based on which client the user belongs to. We currently have a separate build for each client, but as the number of clients increase, it's becoming more of a pain to manage all of those separate releases. My goal is

WPF rendering problem with HWND children in the way

阅读更多关于 WPF rendering problem with HWND children in the way

I suppose it is safe to say that WPF renders its contents as a window background. There are no child windows in a traditional HWND sense. So, when one introduces something HWND based in a WPF app, like a WebBrowser, things start to go wrong way it terms of visual appearance. Consider a Window having a Grid with two children, WebBrowser and something else, e.g. TextBox. If WebBrowser were a red circle instead, the TextBox would render on top of it. In case of WebBrowser, no TextBox is to be found anywhere. This is because TextBox is rendered as main window's background and WebBrowser is

Detecting external content with TEmbeddedWB or TWebBrowser

阅读更多关于 Detecting external content with TEmbeddedWB or TWebBrowser

I am trying to block anything external loaded by TEmbeddedWB or TWebBrowser (or TCppWebBrowser). I would like to block anything that is loaded from Internet including images, javascript, external CSS, external [embed] or [object] or [applet] or [frame] or [iframe], executing JavaScript that can load external content etc. This problem consists of 2 parts: putting web browser into "restrict all" (except basic HTML without images) and detecting if such content exists if external content is not present ok, if it is, showing a "download bar" which after click puts web browser into "download all"

Disable scrolling in browser control for WP7?

阅读更多关于 Disable scrolling in browser control for WP7?

Is it possible to disable the scrolling in a web browser control in Windows Phone 7.1? I have seen quite a few questions ask around it (Windows Phone 7.0, Silverlight) but an answer has yet to come up. Any ideas? There is a blog post here explaining how to suppress the zoom and scroll functionality of the WebBrowser control. Quote from that post: The visual tree is quite simple, composed of a few grids and borders. The significant parts are the TileHost, which is the native IE9 component, and the PanZoomContainer. The TileHost does not handle the mouse manipulation events, these are instead

WPF WebBrowser control doesn't enter design mode when the document property is changed

阅读更多关于 WPF WebBrowser control doesn't enter design mode when the document property is changed

I have a frustrating problem. Here's a simplified version of what I'm doing: A UserControl in c# contains a toolbar and an embedded WebBrowser object. The toolbar contains an "Edit" button, which when clicked sets the webbrowser control in design mode. Another button, "Cancel", turns off design mode. Pseudocode (very simplified): public void SetDesignMode(bool dm) { IHTMLDocument2 doc = webBrowser.Document as IHTMLDocument2; if (dm) doc.designMode = "On"; else doc.designMode = "Off"; _designMode = dm; ReloadDocument(); // setting designmode clears the document element, so it must be reloaded }

WebBrowser Control download file in session

阅读更多关于 WebBrowser Control download file in session

I'm using WebBrowser control to navigate through a login page and download a file. Since I can't find a way to manage the download automatically with the control I'm using the WebClient class to try and achieve this. Problem is that since the WebClient isn't in the same context/session as the browser all i'm downloading is the Security Error screen. Any ideas on how I can pass the context of the WebBrowser session to the WebClient ? Laramie It should be simply a matter of emulating the cookies and headers in the WebBrowser session and re-using them to impersonate the session in WebClient, but

I want to call the javascript function 'Goto' like this : javascript:Goto('DM_NEW_OBJECT.ASPX?DM_CAT_ID=2063&DM_PARENT_ID=2217&INPUTSELECTION=&DM_OBJECT_ID=0&PACK_ID=0&CASE_ID=0&mode=0&SITE=Default'); the function is located in the DefaultGeneral.aspx page, and i need to call it from within a WebBrowser control webBrowser1.Navigate("http://mySite/DefaultGeneral.aspx"); Do you have any idea ? Thank you. Since you are using a WebBrowser object, I will assume that this is actually a Windows forms question and not an asp.net question. You should look at the InvokeScript function of the web browser

问题 I am using Microsoft Visual Studio 2010 C# .net 4.0 I have a webbrowser element. What i want to do is navigating via Webbrowser element with using proxy. How can i do that ? thank you. 回答1: The browser control is just an instance of IE - it will use IE's proxy settings. You can set these by playing with registry keys if you must do it in code. string key = "Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings"; string serverName = "";//your proxy server name; string port = ""; /
