You can't. A For Each loop direction can't be controlled. What you can do is replace it with a for loop:

'' Note: Option infer should be set to ON for this line!
Dim elements = WebBrowser1.Document.GetElementsByTagName("div")
For i as Integer = elements.Length To 0 Step -1
    Dim subele As HtmlElement = elements(i)
Next

If you only need the last element returned from GetElementsByTagName you can simply do this:

Dim elements = WebBrowser1.Document.GetElementsByTagName("div")
Dim subele As HtmlElement = elements(elements.Length-1) ' or perhaps Count, I'm not sure if this method returns an array, a list, or simply an IEnumerable...

The only way I am aware of is by reverse iterating the index like above – Jimmy Smith Dec 13 '17 at 21:13
