' Name: clsTimer
' Description:This code keeps a count in milliseconds of how long it takes between calls of StartTimer and StopTimer or Elapsed.
' By: John Lambert (from psc cd)
'
' Inputs:None.
'
' Returns:.Elapsed returns the number of milliseconds between calls to .StartTimer and .StopTimer. If .StopTimer hasn't been called, it returns the number of milliseconds since .StartTimer was called.
'
' Assumes:Make a class called clsTimer and paste this in there.
Call order is something like:
Dim t1 as new clsTimer
t1.StartTimer
'do something that takes a while
Debug.Print "Right now, current elapsed = " & t2.Elapsed
'do something else?
t2.StopTimer
Debug.Print "Total elapsed = " & t2.Elapsed
'
' Side Effects:No side effects.
'**************************************

' in clsTimer...
Dim start, finish
Public Sub StopTimer()
finish = GetTickCount()
End Sub
Public Sub StartTimer()
start = GetTickCount()
finish = 0
End Sub
Public Sub DebugTrace(v)
Debug.Print v & " " & Elapsed()
End Sub
Public Property Get Elapsed()
If finish = 0 Then
Elapsed = GetTickCount() - start
Else
Elapsed = finish - start
End If
End Property
