reference ms internet controls under project/references:

Dim IE As New InternetExplorer

IE.Navigate "www.google.com"

'wait for page to load
Do Until IE.ReadyState = READYSTATE_COMPLETE
   DoEvents
Loop

Dim strHtml as string
strHtml = IE.document.body.innerHTML

msgbox strHtml

Dim ff as integer

You can use the URLDownloadToFile API

Private Declare Function URLDownloadToFile Lib "urlmon" Alias _
"URLDownloadToFileA" (ByVal pCaller As Long, ByVal szURL As String, ByVal _
szFileName As String, ByVal dwReserved As Long, ByVal lpfnCB As Long) As Long

Use like this:

returnValue = URLDownloadToFile(0, "http://www.microsoft.com/ms.htm", "c:\ms.htm", 0, 0)
