Scripting IE to use dropdown box in VB.Net using SHDocVw

I am trying to write a little program to download some stock prices.  This is an example of the webpage I am trying to hit:

http://www.nasdaq.com/symbol/aapl/historical

In the middle of the page you can see there is a dropdown that says "Select the Timeframe: ".  I would like to change this to 2 years with the program.  This is the code I am using:

Dim wbBrowser As New SHDocVw.InternetExplorer
        wbBrowser.Visible = True
        wbBrowser.Navigate("http://www.nasdaq.com/symbol/drys/historical", Nothing, Nothing, Nothing, Nothing)
        Do
        Loop Until Not wbBrowser.Busy

 Dim HTMLDoc As mshtml.HTMLDocument

HTMLDoc = wbBrowser.Document

 Dim iHTMLCol As IHTMLElementCollection
        Dim iHTMLEle As IHTMLElement
        Dim str As String

iHTMLCol = HTMLDoc.getElementsByTagName("input")

 If Not iHTMLEle.getAttribute("name") Is Nothing Then

     iHTMLEle.click()


 End if

Select allOpen in new window

I was really just using that to try to go through the page elements and find the dropdown, but I can't even find it.  Any ideas on how to interact with the dropdown?
