Me tarde un buen buscando pero ya esta aqui la solucion
En un boton pones :
Private Sub Command1_Click()
hInst = GetWindowLong(Me.hwnd, GWL_HINSTANCE)
Thread = GetCurrentThreadId()
hHook = SetWindowsHookEx(WH_CBT, AddressOf Manipulate, hInst, Thread)
Resultado = InputBox("Intenta escribir letras", "Solo numeros")
End Sub
Insertas un Modulo y pones :
