I use this procedure to compare timings.

The important bits for youo are the call to GetTickCount and the line
calculating milliseconds.

Option Explicit
Declare Function GetTickCount Lib "kernel32" () As Long


Public Sub subCompareSpeed()
' Compare the speed of two procs.
' The overhead of the calls should not matter because
' this is a compare and not trying to measure absolutes.

' Add whatever but leave em here

Dim lnglCounter As Long
Dim lnglMax As Long
Dim lnglTime1 As Long
Dim lnglTime2 As Long
Dim lnglTime3 As Long
Dim strlLineA As String
Dim strlLine As String
Dim strlFirstItemsList As String
Dim blnFound As Boolean

lnglMax = 1000

MsgBox strlLineA
lnglCounter = 0
strlLine = strlLineA
lnglTime1 = GetTickCount()
Do
' subStripTextChrs strlLine
lnglCounter = lnglCounter + 1
Loop Until lnglCounter >= lnglMax
lnglTime2 = GetTickCount() - lnglTime1
MsgBox "Instr took " & lnglTime2 & " ms to finish'"
MsgBox strlLine
lnglCounter = 0
strlLine = strlLineA
lnglTime1 = GetTickCount()
Do
' subStripText strlLine
lnglCounter = lnglCounter + 1
Loop Until lnglCounter >= lnglMax
lnglTime2 = GetTickCount() - lnglTime1
MsgBox "Chrs took " & lnglTime2 & " ms to finish'"
MsgBox strlLine
MsgBox "Done"
End Sub
