Measuring A Program’s Speed

Measuring A Program’s Speed

The simplest way to measure the performance of a block of code (or an entire program) is to obtain the elapsed time. This tip shows you how.

'At the top of the form:Private Declare Function timeGetTime Lib "winmm.dll" () As Long'At the top of the current sub:Dim z As Long'Start measuring the timez = TimeGetTime()'Debug.Print Mid$("abc", 2, 1)'Stop measuring the timez = TimeGetTime() - z'MsgBox "That took " & z & " ms!"
