VBA-计时器功能，可逐步捕获经过的时间

Question

I was looking for a timer function that easily can be embedded in my coeds to show me how many seconds each step is taking. I am doing this with a regular debug.print and several variables which made my code busy and also hard to do subtracting new timer from last recorded step was redundant as well. I am looking for a function to capture the time takes for each step and also finding out the total elapsed time from the first step.

Answer 1

Here is what I developed for that purpose. You have to declare a public object of "Scripting.Dictionary" type and also a long variable as ti.

Late Binding:

Public d As Object, ti as long

and in one you your procedures, prior to calling the function:

Set d = CreateObject("Scripting.Dictionary")

Early Binding

You can use early binding if you have Microsoft Scripting Runtime already added to your library. Your declaration would be like below:

Dim d As New Scripting.Dictionary, ti as long

anyway here is the:

Function

Title is a string as a reminder or tag of the stage/step in the code.
Newstart should set TRUE, for the first instance of the function.
NeedTotal should set true if you want total elapsed time up until that stage.

Public Function gettimer(Optional ByVal Title As String, _
                     Optional ByVal Newstart As Boolean, _
                     Optional ByVal NeedTotal As Boolean)
If Newstart = True Or ti = 0 Then
    ti = 0
    d("T0") = Timer
    gettimer = ti & vbTab & vbTab & "0.00" & vbTab & vbTab & "Start @ " _
    & Format(Time, "h:mm:ss") & vbTab & Title
Else
    gettimer = ti & vbTab & vbTab & Format(Round(Timer - d("T" & ti - 1), 2), "0.00") _
    & vbTab & vbTab & Title
    d("T" & ti) = Timer
End If
If NeedTotal Then
    gettimer = gettimer & vbTab & vbTab & vbTab & "Time elapsed from the start = " _
    & vbTab & Round(d("T" & ti) - d("T0"), 4)
End If
ti = ti + 1
Debug.Print gettimer
End Function
