Podes usar la función ShellExecute de la API de Windows, aca tenes un ejemplo:

Private 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

Const SW_SHOWNORMAL = 1
Private Sub Form_Load()
ShellExecute Me.hwnd, vbNullString, "f:\archivo.html", vbNullString, "f:\", SW_SHOWNORMAL
End Sub
