Setting a cookie in a WebBrowser control

心已入冬 提交于 2019-11-27 04:23:34
I am loading a website using a WebBrowser's Navigate function, and I want the browser to load the page with a cookie I've given it. The following code doesn't work: wb.Navigate(url, null, null, "Cookie: " + cookie + "\n"); What am I doing wrong? Will I have to use InternetSetCookie ? This doesn't seem like the best solution. Kiran Madipally Looks like there is a better way: Import the InternetSetCookie function: [DllImport("wininet.dll", CharSet = CharSet.Auto, SetLastError = true)] static extern bool InternetSetCookie(string lpszUrlName, string lpszCookieName, string lpszCookieData); Create

Add new Microsoft Edge to web browser control?

女生的网名这么多〃 提交于 2019-11-27 04:11:17
The new Windows 10 with Microsoft Edge has arrived. I want to ask you, how can I add it to my web browser control? I need it because the actual web browser control doesn't allow JavaScript and CSS3. I used to also add Chrome browser with the projects WebKit and Awesomium but they didn't remember the login credentials (I need them for my app) so I have to use I.E. unfortunately. UPDATE May 2018: FINALLY Microsoft has made it easy. https://blogs.windows.com/msedgedev/2018/05/09/modern-webview-winforms-wpf-apps/ For now, the new control is in the Windows Community Toolkit 3.0 and contained in

Use cookies from CookieContainer in WebBrowser

烂漫一生 提交于 2019-11-27 04:07:48
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#. 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, string lbszCookieName, string lpszCookieData); public WebBrowserControl(String path) { this.url = path;

Zoom in on a web page using WebBrowser .NET control

筅森魡賤 提交于 2019-11-27 03:59:35
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. There appears to be a solution at IE Zoom that involves overriding AttachInterfaces and DetachInterfaces in the WebBrowser to get a IWebBrowser2 interface, and then calling ExecWB with OLECMDID_OPTICAL_ZOOM . I've tried

WebBrowserSite: how to call a private COM interface method in a derived class?

孤人 提交于 2019-11-27 03:30:01
问题 Here is the challenge. I'm deriving from the Framework's WebBrowserSite class. An instance of my derived class, ImprovedWebBrowserSite , is returned via WebBrowser.CreateWebBrowserSiteBase, which I override in my derived version of the WebBrowser class - specifically to provide a custom site object. The Framework's WebBrowser implementation further passes it to down to the underlying unmanaged WebBrowser ActiveX control. So far, I've managed to override IDocHostUIHandler in my

Masking floating point exceptions with Set8087CW, SetMXCSR and TWebBrowser

若如初见. 提交于 2019-11-27 03:27:23
问题 As I am receiving "Floating point division by zero" exception when using TWebBrowser and TEmbeddedWB from time to time, I discovered that I need to mask division by zero exceptions Set8087CW or SetMXCSR. Q1: What would be the best approach to do this: to mask such exceptions early in the application startup and never touch them again (the app is multithreaded)? to use OnBeforeNavigate and OnDocumentComplete events to mask / unmask exceptions? (is there a chance that exception could occur

WebBrowser control keyboard and focus behavior

拟墨画扇 提交于 2019-11-27 02:37:56
问题 Apparently, there are some serious keyboard and focus issues with WPF WebBrowser control. I've put together a trivial WPF app, just a WebBrowser and two buttons. The app loads a very basic editable HTML markup ( <body contentEditable='true'>some text</body> ) and demonstrates the following: Tabbing is misbehaving. User needs to hit Tab twice to see the caret (text cursor) inside WebBrowser and be able to type. When user switches away from the app (e.g., with Alt-Tab), then goes back, the
