问题 My main purpose is get my current geolocation. I've tried to do it with standart control "WebBrowser" but geolocation is not supported by it.

问题 I have a WPF System.Windows.Controls.WebBrowser control in a Window. A user can enter information and hit a submit button into the webpage displayed by the WebBrowser. After the page posts back it uses a scripting object to communicate with my application. I need to make sure that once the submit button has been pressed, the form doesn't close or otherwise stop waiting for the web page to post back. It would be great if I could check the state of the WebBrowser or its document via a property

问题 I'm creating an application that will heavily use PDF file viewing. Is there a difference/advantage in using WindowsFormsHost over WebBrowser? WebBrowser is just a line of code versus WindowsFormsHost setup. So, I'm curious if there are any advantages of using WindowsFormsHost? 回答1: WPF WebBrowser control runs in IE protected mode by default, and Adobe PDF Reader plugin is known to have issues with that. Check this question. I'd go with WindowsFormsHost and host PDF Reader ActiveX directly,

问题 I am using the System.Windows.Controls.WebBrowser control, and I need to get the height of the rendered html document. (Not the height of the control, the height of the content) The only height value I've found is WebBrowser.Document.body.offsetheight. However, this is the same value as the control's height. I know the height of the page must be stored someplace since the scroll bar knows the value. Everything I find in my searching has been about the Windows.Forms.WebBrowser. 回答1: Add COM

问题 I realize this question isn't exactly up to SO's standards but I'm hoping someone can tell me I'm wasting my time or point me in the correct direction. I'm wondering if there was a low level API for manipulating a web page loaded in Edge. I'm working on an automation project that needs to be able to parse the DOM, inject elements, get / set input values from a separate process in real time. I have not been able to find ANYTHING online that suggests this is possible but I'm worried I might not

问题 What I'm trying to do is get this to print in landscape mode without showing the dialog box. This is what I have so far: ((mshtml.IHTMLDocument2)Browser.Document.DomDocument).execCommand("Print", true, 0); I know that the instruction to print in landscape mode needs to be sent through the third argument, but I don't know how to construct the third argument to do this.
