Open PDF in WebBrowser Control VB.NET VisualStudio 2012

Handling the Navigating event solves the problems described in the last section. Here I don't get binary data, but just the fully qualified file name s that come in as the document's navigation Uri.

With this I can capture the files and based on what types of files I'm dealing with either open the files text files or embed images directly into the document image embedding. Start by hooking up a Navigating handler: WebBrowser. ToLower ; if url.

Contains "editor. Contains "editorsimple.

GetExtension file. StartsWith "..

FileName, docPath ; File. OpenTab e. In my case I only allow my Editor to load so there are two allowable pages - Editor. The first thing is to cancel the navigation - we don't want to actually open a new document in the browser.

If the file s dropped is an image, I want to embed the image as an image link. If the image is in a non-relative path I offer to save it locally otherwise the image is just linked directly. If the dropped file is a text file in one of the supported formats I simply open it in a new tab in the editor.

When it's all said in done, I can now drag images into the editor like this: The same works with text files which open rather than embedding a link. Debugging the Web Browser Control with Firebug Lite Summary Cool - I've been noodling with how to make this work for a while and I was looking in all the wrong places figuring I'd have to deal with Drop events.

Drag and Drop in Windows is always a pain, but with this approach in the Navigating handler I get to bypass that completely. Not obvious, but that's what this post is for. 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 snippet.

Setting WebBrowser.

Url to a valid Uri object. Document property. We simply set WebBrowser.

This, is clearly not what we want. Open, FileAccess. Read ; browser. The WebBrowser control will load the data from the Stream and again, render it into an HtmlDocument object.

The Hurdle What we need to do at this point should be clear: we need to some how modify the HtmlDocument prior to the WebBrowser control rendering it on the screen. I figured there would be an event exposed for this, seemingly obvious, desire. I looked into the following events, hoping for a quick solution: WebBrowser.

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. 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 I can check to see if the file being downloaded is an image, and if so, simply cancel the download. No, that won't work because the FileDownload event simply takes an "EventArgs" 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. As most developers do, I scanned the net to find out if this problem had already been cracked.

I didn't find an exact solution, but I did find something that helped at least spark my imagination. I point you now to the blog of Jim Holmes. I kind of know Jim a little from when I lived in Ohio and went to a few Dayton.

Now, Jim is a very smart guy in fact he has a great O'Reilly Book out right now so I'm not sure what happened, but in his article I think he makes a few mistakes about how the WebBrowser control works and I will point those out when we come to them.

To make our example more simplistic let's just say we don't want images to load at all. My solution, for. NET 3.

You can see the prototype for the ProcessRequest extension about. It takes two parameters a Stream object that contains the "source" of the page and a delegate that takes an HtmlDocument and returns a modified HtmlDocument.

Also, we could have performed all of the operations in this method using the WebBrowser control we were given, but the drawback to that is the control would fire any registered event handlers. We want our manipulation of the HtmlDocument to be as seamless as possible, and thus we operate on a temporary WebBrowser control.

The above chunk of code also performs the mundane task of reading the entire Stream into a string and propagating any exceptions up the stack. Navigate "about: blank" ; Now, the above code contains something that Jim tells us to do which is navigate our browser to "about: blank". As Jim states, correctly, this causes the HtmlDocument object to be created and initially empty.Check your devices documentation or install their PCL print driver and print to file to the tray you want it to output to and you can see what number they use.
