webbrowser-control

问题 Is it possible to get a screenshot of a control in winforms without actually displaying it on the screen? How about a webBrowser component? 回答1: Yes. This can be done. I whipped up a sample program to do it. Forgive my naming conventions and code organization, this was whipped up very quickly. You can modify it to better fit your needs, but this shows the basics. I have a single form with three controls: button1: Button with the default settings. button2: Button with the Visible property set

问题 I have a textBox and a webBrowser control in my Windows Forms application. Whenever a user enters a HTML code in textBox, the webBrowser control shows its compiled form. The code for this: private void textBox2_TextChanged(object sender, EventArgs e) { webBrowser1.DocumentText = textBox2.Text; } But whenever I click a link in the webBrowser control, it opens it in the same webBrowser control. What I want is that it should open in default web browser of the system. So is there any event for

问题 I am trying to load a PDF document inside a .NET web browser control. In versions of Adobe Reader prior to v10 (aka "X"), the PDF loaded without the toolbar displayed—you would just see the PDF document. In the newly-released Reader v10, there is a toolbar that I do not wish to see. I am wondering if anyone knows how to hide this toolbar. I'm thinking that the answer may lie in the Registry, as there is no direct code that I am using to access Reader. Everything is handled by mime types

问题 My software handles navigation to target=_new through this function Private Sub Web1_NewWindow(...) Handles Web1.NewWindow Web1.Navigate(Web1.StatusText) e.Cancel = True End Sub Which allows me to open any new windows inside the same webbrowser control. However, when navigating to a "javascript:" link that creates a new popup, I get the following message because it is trying to navigate to that page: The requested resource is in use. (Exception from HRESULT: 0x800700AA) How can I make it open

问题 I'm working on a WinForms application that is implementing a C# WebBrowser control. This application is deploying to a Windows 7 SP1 Panasonic touch screen device. Many times, the user will be browsing a page containing a very large image. In order to see parts of this image, they will need to scroll horizontally. While the vertical scrolling via finger is fine, horizontal scrolling is very uncooperative. I see we have ScrollViewer.SetPanningMode, but do we have something similar for the

问题 Here is my code: type TForm1 = class(TForm) WebBrowser1: TWebBrowser; Button1: TButton; Button2: TButton; procedure Button1Click(Sender: TObject); procedure Button2Click(Sender: TObject); end; implementation uses ActiveX; procedure TForm1.Button1Click(Sender: TObject); // method 1 var HtmlFile: string; begin HtmlFile := ExtractFilePath(Application.ExeName) + 'test.html'; WebBrowser1.Navigate(HtmlFile); end; procedure LoadHtml(wb: TWebBrowser; HTMLStr: string); var aStream: TMemoryStream;

问题 I have a need to run some automation tasks in a web browser control but I seem to be facing a few limitations/unknowns that I'm not 100% sure how to resolve. The application I'm running is not for public release, so I can enforce a prerequisite that IE8 is installed. GeckoFX (http://geckofx.org) would be great except it does not offer me an acceptable way to manipulate the DOM as I would using the WebBrowser's InvokeMember method on HtmlElement objects. WebKit.net would be even better but it

问题 I have my main gui class with some subclassess. There are +- 3 threads that are collecting data from various internet sources and API gateways etc. Now, out of one of these threads, I want to run a webbrowser control, so I can add some autobrowsing functionality to my program. Each of the sub threads should be capable of opening a webbrowser on its own. So I created a second c# windows form, which contains only the webbrowsing control. I already use the ApartmentState.STA setting on this new

问题 I am trying to automate Webbrowser with .NET C#. The issue is that the control or should I say IE browser behaves strange on different computers. For example, I am clickin on link and fillup a Ajax popup form on 1st computer like this, without any error: private void btn_Start_Click(object sender, RoutedEventArgs e) { webbrowserIE.Navigate("http://www.test.com/"); webbrowserIE.DocumentCompleted += fillup_LoadCompleted; } void fillup_LoadCompleted(object sender, System.Windows.Forms
