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

Open 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?

The HTML for that element:

<select id="ddlTimeFrame" name="ddlTimeFrame" onchange="getQuotes(false)">
            <option value="5d">5 Days</option>
            <option value="1m">1 Month</option>
            <option value="3m" selected="selected">3 Months</option>
            <option value="6m">6 Months</option>
            <option value="1y">1 Year</option>
            <option value="18m">18 Months</option>
            <option value="2y">2 Years</option>
            <option value="3y">3 Years</option>
            <option value="4y">4 Years</option>
            <option value="5y">5 Years</option>
            <option value="6y">6 Years</option>
            <option value="7y">7 Years</option>
            <option value="8y">8 Years</option>
            <option value="9y">9 Years</option>
            <option value="10y">10 Years</option>
        </select>

Open in new window


You should be able to use getElementByID("ddlTimeFrame") to get the HTML element.  You can cast that element to mshtml.HTMLSelectElement.  You should be able to loop through the HTMLOptionElementCollection (options), and find the HTMLOptionElement that you would like to select.  With the correct index for the option, you should be able to set the selectedIndex property for the HTMLSelectElement.
