Recording the time in Excel

Hi, everyone!

I would like to have a small timer in the background of my Excel application. Whenever the user changes a value in any cell in Sheet1, in the same cell in Sheet2 should be written how much seconds it took the user between two changes - that is, e.g., the user writes a value in B4 and then, 12 seconds later, another value in C15. Then, in Sheet2, in cell C15 would stand simply "12". It doesn't really matter, if the programme writes seconds or the standart time format.
I'm looking for a complete solution, that's why I am giving away the maximum points!

hi luchko,

right click your sheet tab
View Code
paste the sub below

Public startt

Private Sub Worksheet_Change(ByVal Target As Range)
Sheets(2).Range(Target.Address) = Timer - startt
startt = Timer
End Sub


Cheers

Dave

a bit tidier on the formatting

Public StartT As Double
Private Sub Worksheet_Change(ByVal Target As Range)
Sheets(2).Range(Target.Address) = Format(Timer - StartT, "##0.0 /secs")
StartT = Timer
End Sub

Hi luchko,
Create a module in your workbook, and paste in the following:

Dim StartTime As Date
Sub ChangeTime()
    StartTime = Now()
End Sub
Sub ChangeCell()
    MsgBox (ActiveCell.AddressLocal)
    Set mc = Worksheets("Sheet2").Range(ActiveCell.AddressLocal)
    mc.Value = Now() - StartTime
    ChangeTime
End Sub

In the Workbook open event (to initialise the value):

Private Sub Workbook_Open()
    ChangeTime
End Sub

And in the Worksheet change event:

Private Sub Worksheet_Change(ByVal Target As Range)
    ChangeCell
End Sub

Now, Sheet2 will contain times from opening the wokbook to entering the first cell, and the interval between cell changes.

luchko,
You don't really need a timer, the interval between one cell change and the next seems to be what you're looking for.

Thank you a great lot! Could you also please tell me if I could somehow use the usual format xx:xx:xx as well?
DaveCommented:
sure, try

Public StartT As Double
Private Sub Worksheet_Change(ByVal Target As Range)
Sheets(2).Range(Target.Address) = Format(Now() - StartT, "hh:mm:ss")
StartT = Now()
End Sub

Cheers
