Uploading a photo to a dropzone web page programmatically.

This is the line that I am after.

<input id="html5_7956" type="file" accept="image/jpeg,image/gif,image/png,image/bmp" multiple="">

My question is this. How do I take the type "file" and replace that with the path from my computer as the input request?

I can do this in PHP, but not a clue of the syntax of which class to follow to get this done in vb.net and PHP doesn't help cause I didn't write the other PHP file to receive the post information from.

Code:

---

            If (WebBrowser1.Document IsNot Nothing) Then
                Dim Elems As HtmlElementCollection = WebBrowser1.Document.GetElementsByTagName("input")

                For Each elem As HtmlElement In Elems
                    Dim AttStr As String = elem.GetAttribute("type")
                    If AttStr = "file" Then
                            'What goes here?
                    End if
                Next

---

End If
