Use Excel VBA to fill out and submit Google Docs form

Question

I'm trying to do something like this post but with Excel VBA. I would like to submit a response on a google docs form each time a button is pressed on an Excel add-in. The addin will be an XLA file and written in VBA.

I want to be able to collect what features the users are using. If someone has a better solution, I'm open.

---Edit---

This is the form I am trying to write to (excerpt of the code for one of the fields.)

<div class="errorbox-good">
    <div class="ss-item ss-item-required ss-text">
        <div class="ss-form-entry">
            <label for="entry_0" class="ss-q-title">
                UserName
                <span class="ss-required-asterisk">*</span>
            </label>
            <label for="entry_0" class="ss-q-help"></label>
            <input type="text" 
                   id="entry_0" 
                   class="ss-q-short" 
                   value="" 
                   name="entry.0.single">
        </div>
    </div>
</div>

--EDIT 2-- This is what I've tried so far, but it is still not working. I am getting an error on the line that says ".UserName.Value = Environ("username")" I suspect it is because it is not finding the item .username.

Answer 1

The best solution I could find was to use sendkeys. I know it is less than ideal, but without any other feedback here, and with my limited knowledge it is best I could come up with. I have accepted this answer, and because of the bounty request I can't undo the acceptance, but if there is a better idea post here and and I will upvote and leave a comment stating it is the answer.

Sub FillOutGoogleForm()
    Application.ScreenUpdating = False
    Dim IE As Object
    Dim uname       As String
    Dim ukey        As String

    uname = Environ("username")
    ukey = "00000-123kd-34kdkf-slkf"

    Set IE = CreateObject("InternetExplorer.Application")
    IE.Visible = True

    While IE.busy
        DoEvents
    Wend

    IE.navigate "http://spreadsheets.google.com/viewform?hl=en&pli=1&formkey=dHFTMzkwR2RpY2tzSUNnbVhIcDN3WWc6MA"

    While IE.busy
        DoEvents
    Wend

    SendKeys uname
    While IE.busy
        DoEvents
    Wend
    SendKeys "{TAB}", True
    SendKeys ukey
    While IE.busy
        DoEvents
    Wend
    SendKeys "{TAB}", True
    SendKeys "{ENTER}", True
    SendKeys "%{F4}"
    Application.ScreenUpdating = True
End Sub
