Webbrowser control authenticate not working when access file folder

阅读更多关于 Webbrowser control authenticate not working when access file folder

I have a .Net 2.0 WinForm application, it has a WebBrowser control which is used to access a secured network drive, this network drive only granted access to a few special account and the application needs to impersonate one reader account to read the PDF file. I used the LogonUser and the application was able to impersonate the reader account to see the file names under the folder, but then when I use webBrowser1.Navigate(new Uri(filePath))m, I got access denied. So after research, I know that I must do the COM stuff which I have never used before. Ok, after many hours online and trial/error,

How to register own protocol using the WebBrowser control?

阅读更多关于 How to register own protocol using the WebBrowser control?

In a WP7 Silverlight application with a WebBrowser control I want to use an own protocol like "myttp://" to deliver some local content. I can't use Navigate() to an IsolatedStrorage because some content will by created on demand. For the same reason NavigateToString() is also not usable for me. I tried to register a WebRequestCreator descend for my MYTP protocol myCreator = new MyRequestCreator(); WebRequest.RegisterPrefix("mytp://", myCreator); but it isn't called from the browser control if I navigate to "mytp://test.html". If I create a WebRequest via code WebRequest request; request =

DEL and BACKSPACE keys get eaten from WebBrowser

阅读更多关于 DEL and BACKSPACE keys get eaten from WebBrowser

I have a custom task pane in a VSTO Outlook add-in which hosts a System.Windows.Forms.WebBrowser control. All works well but in web forms DEL and BACKSPACE keys do not work. As if something eats those keys before they get to the browser. Any pointers are appreciated. EDIT: It seems that clicking the WebBrowser does not activate the parent task pane. If I add a simple TextBox as a sibling to WebBrowser and then click TextBox with a mouse, task pane's title bar color changes indicating it got focus. Next if I click WebBrowser , Del and Backspace start working. If I remove focus from task pane

Suppress about:blank in Print Output of WinForms WebBrowser

阅读更多关于 Suppress about:blank in Print Output of WinForms WebBrowser

I'm updating a WinForms application that uses System.Windows.Forms.WebBrowser to output some HTML content generated by the program.

The client does not want to assume the presence of any third-party software such as Excel or even a PDF reader. public void ClearBrowserPrintHeaderAndFooter() { string path = "Software\\\\Microsoft\\\\Internet Explorer\\\

Removing border from WebBrowser control

阅读更多关于 Removing border from WebBrowser control

I've got a WebBrowser control sitting on a Form which has an irritating 2px inset-looking border around it. It's causing my content to be clipped by 4 px on the right and bottom, and I can't figure out how to get rid of it. The control itself doesn't have any BorderStyle properties -- how does one remove the border? See the red area in the screen shot: Make it stop! http://img229.imageshack.us/img229/8342/badbadwebbrowser.gif I want the WebBrowser to look like the blue area -- that is, to fill the Form and be flush against the Form's edges. IE draws that as part of the default style on the

I have a winform and a WebBrowser control and I am changing an option in select HTML control. webBrowser1.Document .GetElementsByTagName("select")[4] .GetElementsByTagName("option")[13] .SetAttribute("selected", "true"); Now it works and selects the required option, but it does not fire the onchange event.
