Hi I was wondering if it is possible to to set the DocumentStream of the WebBrowser control to the stream that is returned from a. I have a WebBroswer control that is displaying xml formatted with xslt. I need to convert the ntStream to an xps byte[]. A reference to an implementation of the IWebBrowser2 interface could not be retrieved from the underlying ActiveX WebBrowser control.

Fun with the WebBrowser Control

Download Solution - OfflineHtml. The WebBrowser control is essentially a managed wrapper around some COM interfaces that documentstream webbrowser to Internet Explorer and provides us with several interesting capabilities.

First of all, one can use WebBrowser to easily display a web page in a WinForms application. All you have to do is set the WebBrowser.


Url property and the control takes care of getting the assets from across the wire and rendered on the screen. WebBrowser also exposes some interesting events documentstream webbrowser allow a programmer to react when a document is loaded, navigation is peformed, etc. WebBrowser read from Stream

There are probably a ton of places, including MSDNwhere you can get that kind of information so I won't go over it here.

Instead, I am going to show something that isn't immediately obvious, but that I believe I found a clean solution to. Similar to say, loading a web archive in Internet Explorer. For our purposes let's use the Google Home Page as an example.

The First Attempt I immediately set upon this task thinking documentstream webbrowser would be pretty easy. For example, the following code demonstrates setting all of documentstream webbrowser "src" attributes of the HtmlDocument's img tags to the empty string: This is great, but how do we actually get the WebBrowser control to load an HtmlDocument for us?


There are three primary methods, each of which I'll demonstrate with a code documentstream webbrowser. Url to a valid Uri object. We simply set WebBrowser.


This, is clearly not what we want. The WebBrowser control will load the documentstream webbrowser from the Stream and again, render it into an HtmlDocument object. The Hurdle What we need to do at this point should be clear: I figured there would be an event exposed for this, seemingly obvious, desire.

I looked into the following events, hoping documentstream webbrowser a quick solution: We can still modify the HtmlDocument at this point, but since any referenced resources have already been downloaded, it is of little value in our situation. ProgressChanged - This event is fired as the page and its resources are being gathered.

NtStream - C# Discussion Boards - CodeProject

It is fired asynchronously, so be very careful when using it. Unfortunately, this too did not work. FileDownload - Aside from DocumentCompleted, this seemed the most promising.

After all, perhaps Documentstream webbrowser can check to see if the file being downloaded is an image, and if so, simply cancel the download.

WebBrowser read from Stream

No, that won't work because the FileDownload event simply takes an documentstream webbrowser parameter and therefore gives us no meaningful state on which to operate. So, at this point we have no way of using events to accomplish our task.

We have to find another way.
