VBA Word Create class module object from normal.dotm - vba

Question

I set up my own library with functions and subs for VBA (Word) and wanted to create a new class module. But I can't figure out how to use this new class with other files.
StopWatch Example (Normal.dotm, Class module: Global_StopWatch)
Private mlngStart As Long
Private Declare PtrSafe Function GetTickCount Lib "kernel32" () As Long
Public Sub StartTimer()
mlngStart = GetTickCount
End Sub
Public Function EndTimer() As Long
EndTimer = (GetTickCount - mlngStart)
End Function
StopWatch call (Document.dotm, module: Test)
Sub swTest()
Dim gSW As Global_StopWatch
Set gSW = New Global_StopWatch
gSW.StartTimer
Debug.Print "That took " & gSW.EndTimer & " ms."
End Sub
Can someone help with this?

Answer 1

Normal.dotm - clsStopWatch (Instancing = PublicNotCreatable)
Option Explicit
Private mlngStart As Long
Private Declare PtrSafe Function GetTickCount Lib "kernel32" () As Long
Public Sub StartTimer()
mlngStart = GetTickCount
End Sub
Public Function EndTimer() As Long
EndTimer = (GetTickCount - mlngStart)
End Function
Normal.dotm - Module1
Public Function StopWatch() As clsStopWatch
Set StopWatch = New clsStopWatch
End Function
Document1 - Module1
Sub Tester()
Dim sw As normal.clsStopWatch, i As Long
Set sw = normal.stopwatch
sw.StartTimer
For i = 1 To 10000000#
'
Next i
Debug.Print sw.endtimer
End Sub
