You may need to use the code timer SetTimer and KillTimer API function.

Code:
'Code under Basic Module File
Option Explicit
Public Declare Function SetTimer Lib "user32" (ByVal hwnd As Long, ByVal nIDEvent As Long, ByVal uElapse As Long, ByVal lpTimerFunc As Long) As Long
Public Declare Function KillTimer Lib "user32" (ByVal hwnd As Long, ByVal nIDEvent As Long) As Long

Sub TimerProc(ByVal hwnd As Long, ByVal nIDEvent As Long, ByVal uElapse As Long, ByVal lpTimerFunc As Long)
   MsgBox "Time UP!"
End Sub

Private Sub Form_load()
    '1 second = 1000ms
    '1 min 5 sec = 65000ms
    "Create a Code Timer
    SetTimer Me.hwnd, 0, 65000, AddressOf TimerProc
End Sub

Private Subn Form_QueryUnload()
    'Kill the Code Timer
    KillTimer Me.hwnd, 0
End Sub
