Bad luck, someone has responded just before me, by the way, here is my response :

Use the following function, to view an HTM file with its associated default browser :

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

Public Function ExecuteWithAssociate(ByVal hwnd As Long, sExecute As String, Optional Param As Variant, Optional windowstyle As Variant) As Boolean

   i = ShellExecute(hwnd, vbNullString, sExecute, IIf(IsMissing(Param) Or (Param = ""), vbNullString, CStr(Param)), GetPath(sExecute), CLng(windowstyle))
   If i > 32 Then
      ExecuteWithAssociate = True

      GetPath = ""
   Else
      GetPath = Left$(s, J)
   End If

End Function
