Change from Early to Late Binding

Could someone assist me in converting from early to late binding.  My attempts at changing the delcarations and set statements have given me a runtime error '420' ActiveX component can't create object.  This was working fine using early binding, however the situation requires a late binding solution.  I have simplified the Code somewhat to make it readable.  

Public Function GetMap(strValue As String)
'need shdocvw.dll - Microsoft Internet Controls
Dim strUrl As String
Dim shlShellWindows As Object
Dim expExplorer As Object
Set shlShellWindows = CreateObject("SHDocVw.ShellWindows")
strUrl = "www.google.com"

On Error Resume Next
'Build the url string
strUrl = strUrl & strValue
'Check and see if there are any open map windows to reuse
For Each expExplorer In shlShellWindows
  If Left(expExplorer.LocationName, 7) = "Mapping" Then
    expExplorer.Navigate strUrl
    Exit Function
  End If
Next
'Open browser window and launch map
Dim ie As Object
Set ie = CreateObject("SHDocVw.InternetExplorer")
ie.Navigate strUrl
ie.Visible = True
Set expExplorer = Nothing

End Function

Guys, I need to stick to the Microsoft Internet Controls dll if possible.  In code Im checking all internet explorer windows currently open to see if they are already at the site I need them to be.  If they are, I grab that window and change the LocationName.  If none of those windows are of the specified website, I open a new internet explorer window and navigate to a url.

This is the offending line:
Set shlShellWindows = CreateObject("SHDocVw.ShellWindows")

Don't think you can call

Set shlShellWindows = CreateObject("SHDocVw.ShellWindows")

because it is hidden and must be go through the object to create.

I try this one

Set shlShellWindows = CreateObject("Shell.Application")

but has no luck

The other one should be

Set ie = CreateObject("InternetExplorer.Application")

Ok, heres what worked finally:
Public Function GetMap(strValue As String)
Dim strUrl As String
Dim shlShellWindows As Object
Dim expExplorer As Object
Set shlShellWindows = CreateObject("Shell.Application")
strUrl = "www.google.com"

'Build the url string
strUrl = strUrl & strValue
'Check and see if there are any open map windows to reuse
For Each expExplorer In shlShellWindows.Windows
  If Left(expExplorer.LocationName, 7) = "Google" Then
    expExplorer.Navigate strUrl
    Exit Function
  End If
Next
'Open browser window and launch map
Dim ie As Object
Set ie = CreateObject("InternetExplorer.Application")
ie.Navigate strUrl
ie.Visible = True
End Function
