How can I display a .mht file on a webBrwoser control?

The title says it!

Your help would be greatly appreciated.

It looks to me like you're out of luck for now. Until Microsoft lets us set the MIME type of the document, you may have to do something like this:

            //get the bytes of the MHT file from the resources of this application
            byte[] mht = global::MyNamespace.Properties.Resources.Testing;
            string filename = Environment.GetEnvironmentVariable("TEMP") + @"\tmp.mht";
            //save the bytes back to a file
            File.WriteAllBytes(filename, mht);
            //load the file in the browser
            webBrowser1.Url = new Uri(filename);

I cannot come up with a way to tell the web browser control what MIME type it is suppose to be using to open the memory stream. Bob, have you had any luck?

Thanks.

Ok, I've got to ask: did you mean .htm?

I'm wondering if the issue is the file or how to display it.

Thanks.

I believe that the title is correct--.mht and not .htm.  mht is a single-file type that has a structure that doesn't require external files, like images.  What happens if you navigate to the .mht file?

Thanks Bob.

AngryC,

You should be able to set the .Url property of the WebBrowser control to the uri (translate: path) of the file. So, if for example, the .MHT file (test.mht) was on your desktop, the code would be:

webBrowser1.Url = new Uri(Environment.GetFolderPath(Environment.SpecialFolder.Desktop) + @"\test.mht");

Thanks.

Thanks for your follow-ups.

I acually know it's possible to load a file if it's saved. But what I'm trying to do is to load the mht file from resource as follow:

webBrowser1.Document.Body.InnerHtml = global::WindowsApplication1.Resource1.MyMhtFileName;

What I am getting is a page that looks like it was opened with notepad not with IE!!!

Please help.

1) >>opened with notepad
What does that mean?  Are you losing the HTML formatting?

2) What is WindowsApplication1.Resource1.MyMhtFileName returning?

3) What encoding are you using?

1) Yes. I'm losing the HTML formatting.

2) The file source (string).

3) I'm not specifying any but I'm sure it's not a matter of encoding. I think I should change the MIME type the webBrowser control. But I don't know how...

1) This is header from an .mht file:

From: <Saved by Microsoft Internet Explorer 5>
Subject: Online Account Services
Date: Mon, 19 Dec 2005 08:41:51 -0500
MIME-Version: 1.0
Content-Type: multipart/related;
      type="text/html";
      boundary="----=_NextPart_000_0000_01C60478.0E7B3520"
X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2900.2180

This is a multi-part message in MIME format.

2) How did you embed the value for MyMhtFileName?

There's no problem with my mht file, it's working when I'm doing this:

webBrowser1.Url = new Uri(Environment.GetFolderPath(Environment.SpecialFolder.Desktop) + @"\test.mht");

I'm also getting the exact content file the file from the resource without any problem, the problem is how can I send it to the webBrowser control?

Is saving the contents back to a file an option? If so, you could write the resource back to a file in the temp folder and then give the browser control its path. Just a thought.

I didn't say that there was a problem with .mht.  It looks like you are trying to extract the file as an embedded resource from the assembly, so I am trying to figure out how it is getting mangled.

I want to load it directly from the resource. I don't want to save the file on desk before using it.

Yes, but when you are loading it from the resource, then it doesn't look correct, so I am trying to figure out why.
