In the VBA, a simple second timer is easy to write and include in the source code. The VBA comes with a full-featured timer which can be used whenever required. However, it is not compulsory to use the timer provided with the VBA. Timer control in the VBA can be done through a manual timer too. It is not a complicated task to create a manual timer function in the VBA. One needs to write the code to create a timer in a public module. With the VBA, a simple second timer can be created to enhance and customize the Office software especially for Excel worksheets.
In VBA there is Timer feature available, but you can also create one very easily.
In a module sheet:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
'For example: Start / Stop the timer every time the cell.
'but may also be placed on a button or another ...
TimeOnOFF = Not TimeOnOFF
If TimeOnOFF Then Timer
In a public module:
Public TimeOnOFF As Boolean
Dim S As Integer
While TimeOnOFF = True
If Second(Now) > S Or Second(Now) = 0 Then
' Run code
Sheets("shee1").Range("A1").Value = Time
S = Second(Now)
