Based on the process outlined here, http://www.codeproject.com/Articles/28917/Setting-a-file-to-upload-inside-the-WebBrowser-com, I'm looking for help incorporating this into my vb.net project.

Let's start by converting to VB.NET:

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            HtmlDocument doc = webBrowser1.Document;
            for (int i = 0; i < doc.Forms.Count; i++)
            {
                HtmlElement form = doc.Forms[i]; // must be declared inside the loop because there's a closure
                if (form.GetAttribute("enctype").ToLower() != "multipart/form-data") { continue; }
                
                form.AttachEventHandler("onsubmit", delegate(object o, EventArgs arg)
                    {
                        FormToMultipartPostData postData = new FormToMultipartPostData(webBrowser1, form);
                        postData.SetFile("file", @"C:\windows\win.ini");
                        postData.Submit();
                    });
                form.SetAttribute("hasBrowserHandler", "1"); // expose that we have a handler to JS
            }
        }

To simplify your code, you should remove the Namespace FormToMultipartPostData...End Namespace lines.  C# code had namespace, but it is not needed in VB.NET.

Ok, as-is, it doesn't seem to be applying the file path.  Fortunately with the appliance it will always be the same file.
(removing the namespace corrected the problem from above).

Since I don't quite understand the code, I'm not sure what I should be looking for.  Could it be that the SetFile method is looking for "file" and it's actually labeled something different on the page?  Or am I looking in the wrong direction?

I'm wondering if the problem is that the box where the file name ends up, is greyed out - and you cannot type in it - you must choose the browse button to upload.
Still possible with this code?

There is a problem with the VB.NET conversion here:

form.AttachEventHandler("onsubmit", delegate(object o, EventArgs arg)
{
     FormToMultipartPostData postData = new FormToMultipartPostData(webBrowser1, form);
     postData.SetFile("file", @"C:\windows\win.ini");
     postData.Submit();
});

The delegate function is known as an anonymous function.  It attaches new code to the onsubmit event handler.

Ok, that makes it a little bit clearer for me, thanks.
But (a) does that eliminate the need for me to locate the browse button and 'click' it?  and (b) I've tried it both ways and neither route seems to be doing anything.

Yes, there is a link to download the current config (it has never really worked when I tried it), but we just append to an existing external config file sitting on a share.

The way I'm interpretting this is that we've setup an event hanlder for when the page attempts to submit the file, but there doesn't seem to be a way to actually submit the file, or is that what clicking the browse button should trigger?  Because that seems to move away from the scope of the page and generate a popup dialogue that's no longer associated with the web page.  Should this event handler be able to manipulate that dialogue?

Could it be that the event handler is named incorrectly?
Is the "hasBrowserHandler" attribute still applicable (I'm not sure what the benefit is for that)?
I did try putting a breakpoint at OnSubmit, but it doesn't hit it.  I also adjusted the code to set the handler before clicking the browse button:

I just noticed something in the code that you posted:

This means if the enctype attribute is not "multipart/form-data", then skip.

The form enctype is here:

enctype="application/x-www-form-urlencoded"

It never hit the input, file case element.

It seems to loop through the doccompleted sub multiple times after I click the save button.
No script errors this time, but about the 3rd time it hits the completed sub, it doesn't find the browse button, so errors on the missing object.  And the page now looks like it didn't completely load.
I let the sub finish out and tried a refresh, but it's still not uploading  the file.
I know when it has new config data, because there's a section on the header that states an update to all nodes is needed...

1) The "target" attribute is not specified, and that's OK, since you don't need it (target frame).

            Case "FILE"

First pass to GetValuesFromForm,
child.TagName = "A" so it skips, next it's "INPUT" but "type" attribute is 'hidden',
so it hits the case else and adds "hidden" with a value of '1'
Third time it's "INPUT" with 'hidden' and a value of a really long string of seemingly random characters.
It doesn't return after this.

According to the sample project, you need to attach an event handler to the "onsubmit" event:

When the event doesn't get raised, it is because there is no submit.  That should happen on the <input type="file"> element, which we are having a problem finding.

I think this is why it's not making sense to me...
The only 'event' that I see in the source is when the save button is clicked.  There is no action shown for the browse button.  Are we assuming we can technically skip that procedure and just ensure that the file value gets populated correctly and then submit via the save button?  Or should I focus on actually clicking the browse button and that somehow is inserting the file into the popup dialogue?

This is pretty complex, so let's review:

1) Attach an event handler to the "onsubmit" event.

2) The <Save> anchor, when clicked, raises the "submit" event.

3) Find an <input type="file"> HTML element.

4) When the "onsubmit" event is raised, handle it.

5) Let JavaScript know that the client-side event was handled by external handler:
form.SetAttribute("hasBrowserHandler", "1")

6) The FormToMultipartPostData.Submit method uses a POST to get the file bytes, and upload to the server.

All these steps need to work correctly, or the upload will not occur.

That is never a silly question when working with C# and Javascript, but as a VB.NET programmer it makes sense that you think it is silly.  Case does matter in most cases.

This line will submit the page:
form.submit()

If you have attached to the correct handler, then the event should be handled by the VB.NET code.

Yes, you should be focused on that, since it calls the oamSubmitForm, which in turn calls the form.submit(), which raises the "onsubmit" event, which is handled by the code.

Ok, so backing up to your outline above...only step #1 is definitely completed/working.
I'm unsure that the save anchor being clicked is raising the submit event.  Based on what I'm seeing, it is not, or at least it's throwing a script error first that may or may not be interfering.  Suppressing the script errors doesn't seem to do anything.

I'm going to step through the forms.count loop and see if I can determine any uniqueness there.
I also moved the form.raiseevent("submit") within this loop, after the hasBrowserHandler is set.

Within there, I see the INPUT file type:
<INPUT id=zdmSummaryDetailsSubview:relContentViewpc1:tabZDM
Service:tabZDMServiceSettings:zdmDetailsForm:msglockfileupload class=formField size=40 type=file name=zdmSummaryDetailsSubview:relContentViewpc1:tabZDMService:tabZDMServiceSettings:zdmDetailsForm:msglockfileupload>

and I also see the save anchor element:
<A id=zdmSummaryDetailsSubview:relContentViewpc1:tabZDMService:tabZDMServiceSettings:zdmDetailsForm:saveZDMSessionConfig class=ButtonLeft onclick="return oamSubmitForm('zdmSummaryDetailsSubview:relContentViewpc1:tabZDMService:tabZDMServiceSettings:zdmDetailsForm','zdmSummaryDetailsSubview:relContentViewpc1:tabZDMService:tabZDMServiceSettings:zdmDetailsForm:saveZDMSessionConfig');" href="#">

So since I'm clicking the anchor element, I need to somehow associate the INPUT file type to reference the external file, correct?

In the form loop, it hits i=6, as expected, attaches the event handler to "onsubmit", sets the attribute "hasBrowserHandler" to 1, and that's where I attempt the form.RaiseEvent("submit").  Hitting that line throws an ArgumentException was unhandled by user code: Value does not fall within the expected range.

<sigh> - It was all so 'easy' compared to this... :\

Took a step even further back, just to see if I could get 'any' success clicking an anchor.
So, immediately after logon, I grab the anchor for the Service tab and try to click, but it's coming up as 'nothing' when choosing HTMLAnchorElement.  Could it be that these should be defined as something besides an anchor? :\

Don't know why I had such trouble locating the Service tab, but once I did, by stepping throuh to the GetHtmlElementById, I was able to locate it.  Once clicked, however, and this is only changing tabs, it barfed on the window.external script error again.  Looks like that's expecting a value each time that function is called.

I'm guessing this part of the function is ensuring it's not a mobile device, and attempting to enable autocomplete?  Though I don't know why, or how to disable that, it appears to be the only source of this window.external in the source.

You need to pass the correct User Agent string in the headers, that includes "msie" in the request headers, since it really is Internet Explorer, which is why it barfs on the AutoCompleteSaveForm.

Although I'm seeing a lot more in fiddler now, I'm not sure how to implement it.
The user agent method above indicates to use .navigate to pass the user agent, but if I'm grabbing an anchor reference, I don't have .navigate.

However, I did get a successful "service tab" click/navigate using:

WebBrowser1.Navigate(Site.Uri.ToString, "_self", Nothing, "User-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; InfoPath.3; .NET4.0C; .NET4.0E; MS-RTC LM 8)")

Would I just replace the .click method with a navigate to the href="#"?  So long as I can locate and modify the file= attribute?

Would that be the first time that you navigate to a URL?  I would think that you need to send it on every navigate.  Another possibility might be to create a custom WebBrowser class, and in the BeforeNavigate, set the user agent.

public class ExtendedWebBrowser : WebBrowser
{
    bool renavigating = false;

    public string UserAgent { get; set; }

    public ExtendedWebBrowser()
    {
        DocumentCompleted += SetupBrowser;

        //this will cause SetupBrowser to run (we need a document object)
        Navigate("about:blank");
    }

    void SetupBrowser(object sender, WebBrowserDocumentCompletedEventArgs e)
    {
        DocumentCompleted -= SetupBrowser;
        SHDocVw.WebBrowser xBrowser = (SHDocVw.WebBrowser)ActiveXInstance;
        xBrowser.BeforeNavigate2 += BeforeNavigate;
        DocumentCompleted += PageLoaded;
    }

    void PageLoaded(object sender, WebBrowserDocumentCompletedEventArgs e)
    {

    }

    void BeforeNavigate(object pDisp, ref object url, ref object flags, ref object targetFrameName,
        ref object postData, ref object headers, ref bool cancel)
    {
        if (!string.IsNullOrEmpty(UserAgent))
        {
            if (!renavigating)
            {
                headers += string.Format("User-Agent: {0}\r\n", UserAgent);
                renavigating = true;
                cancel = true;
                Navigate((string)url, (string)targetFrameName, (byte[])postData, (string)headers);

Which edition of Visual Studio 2010 do you have?  Do you have the ability to record Coded UI tests?

How to: Create a Coded UI Test
http://msdn.microsoft.com/en-us/library/dd286681(v=vs.100).aspx

Using Visual Studio Premium or Visual Studio Ultimate, you can create a coded UI test that can test that the user interface for an application functions correctly

Well apparently 'permission' will be very hard to come by. :(
Nonetheless, I'm still testing.  I'm going to run through fiddler once more and try to build a new project from the ground up using what I find there.  Hopefully the new/fresh perspective will help.

I was curious what edition you were using after some out-of-the-box thinking.  With Coded UI unit tests, you can record a test, generate some code, and play it back with different arguments, which might get you what you need.

I've walked through recreating the entire thing from scratch...though I didn't use mshtml this time.
Everything works up until that point. :(

In Fiddler, I can see that it's setting the input, type=file, value to the path of the csv.
Yet, when I try to use setattribute against that, it remains blank.  I'm guessing because that field is essentially 'locked' unless using the browse button, so I'm wondering if I'm back to trying to track down the handle of the file dialogue...

Yep, once I programmatically clicked the browse button and selected the file, it's holding the "value" attribute... ugh.

Can you explain what you mean by that?  

You can't set the value attribute for the <input type="file">, since it is a security violation.  This whole exercise has been detecting the submit, and posting the file.  I am lost why that didn't work as expected.

I think I know why - I had previously been focused on grabbing the button ID.
Re-reading that site I've modified that to grabbing the correct form ID and now it's working through the loop and located the FILE element...stay tuned.

I don't know if I'm more hard-headed or more ignorant, but I think much of this is starting to make more sense to me...

So, here's what I'm seeing now:
Still throws the script error (window.external) on the button click, but I don't know how the useragent can be added to a click event (like we had with the navigate method).

It runs through the GetValusFromForm - it does locate the "FILE" element, but obviously it's blank.
But it includes several of the other settings that it's passing.
It returns to the event handler, and sets the file (I changed this to "filename" since it's actually showing in fiddler as filename).

Right before postData.Submit(), I examine the data.
I have 8 values (the aforementioned settings) listed in PostData.values (count=8).
I have a files (count=1) property as well.
For PostData.Files(0) I have
name:"zdmSummaryDetailsSubview:relContentViewpc1:tabZDMService:tabZDMServiceSettings:zdmDetailsForm:msglockfileupload"
value: ""

I would have expected that to be the path of the file... :(

As it continues through to GetEncodedPostData(),
headerTemplate is equal to
"Content-Disposition: form-data; name="{0}"; filename="{1}"  Content-Type: application/octet-stream    "

Since the file path was empty, I forced it in that same routine, and it got to the point where it read the file and added it to the memStream, but I couldn't tell once it hit the navigate if it worked. (Hope that makes sense)

Tried hard coding it in there, but it didn't seem to take the file.
I'll run through again after I grab a bite and turn fiddler back on to try to see if I can find the difference.

Meanwhile, do you know of a way to have the .Click() procedure include the UserAgent?  Not sure if that sorts it, or if I need to ensure that it's added in this additional class...just thinking outloud.

There are two indications that I could think of:

2) The file didn't upload

I'm finding the reference for hasBrowserHandler to be hasBrowserHandlers and instead of a value of 1, examples show a value of "true".
I'm not sure if setting attributes for both versions is a bad idea or not...so I've been flip-flopping them.

Not sure if that's eliminated my script error, or my change to
form.RaiseEvent("onsubmit")...  
But, running fiddler again, it almost seems like it's only pushing part of the file.  The details of that field don't scroll all the way down as if it's been truncated.  I'm thinking maybe it has something to do with that error I'm seeing repeatedly about Content-length mismatch...

Looking through the working session vs non-working session today.
I see the definition passed for content-type was application/octet-stream, but the
working session shows it as "vnd.ms-excel", so I've changed that in the code.

These other things, I'm unsure of, but pointing out what I see as far as differences:
Obviously these lines are different, but I think they're unique per session:
------------------------------8d183179e024d12
However, I did see the automated version had one additional hyphen, so I shortened that in the code.

The non working session has an empty/line feed at the top.

Both have 'form-data' for defaultDomain, msgFormat, sessionTimeout, identityTimeoutPolicy,
identityTimeout, and identityTimeoutUnit - values all correct.

Removing that, they both have
Content-Disposition: form-data; name="zdmSummaryDetailsSubview:relContentViewpc1:tabZDMService:tabZDMServiceSettings:zdmDetailsForm_SUBMIT"; (value of 1)

but these are in different places within the session data (not sure if that matters?)

The working session has one additional form-data info, that I don't see in the non-working session:

Content-Disposition: form-data; name="zdmSummaryDetailsSubview:relContentViewpc1:tabZDMService:tabZDMServiceSettings:zdmDetailsForm:_idcl"

zdmSummaryDetailsSubview:relContentViewpc1:tabZDMService:tabZDMServiceSettings:zdmDetailsForm:saveZDMSessionConfig
-----------------------------7de1684362508--


Finally, this may be nit-picking, but the working session shows this line:
Content-Disposition: form-data; name="javax.faces.ViewState"
The non-working has a trailing semi-colon (;).
