Ciao, non ho capito bene cosa intendi, comunque se vuoi aprire una pagina web con il browser predefinito sul PC dell'utente usa questo codice:

------Nel form:------------------

Public Sub Naviga(Form As Form, ByVal WebPageURL As String)
Dim hBrowse As Long
On Error Resume Next
hBrowse = ShellExecute(Form.hWnd, "open", WebPageURL, "", "", SW_SHOW)
On Error GoTo 0
End Sub

Private Sub cmdApripagina_Click()
Call Naviga(Me, "http://www.xxxxxxxxxxx.com/")
End Sub

------In un modulo:----------------

Public Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hWnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long
Public Const SW_SHOW = 1


Spero di esserti stato d'aiuto!
Ciaoo
