如何在Excel中停止当前正在运行的计时器？

Question

我想在Excel中停止当前正在运行的计时器。到目前为止，我已经使用下面的代码在excel中启动计时器，但是我想放置一个按钮，该按钮可以通过VBA在excel表格中停止当前正在运行的计时器。

Dim xRng As Range
Dim oDict As Object

Sub StartTimer() 
    Set xRng = Application.ActiveSheet.Range("D2")
    Set oDict = CreateObject("Scripting.Dictionary")    
    Call PopDict 
    Call Timer 
End Sub

Sub Timer()
    Dim gCount As Date gCount = Now + TimeValue("00:00:01")
    Application.OnTime gCount, "ResetTime"
End Sub

Sub ResetTime() 
    If xRng.Value > 0 Then 
        xRng.Value = xRng.Value - TimeSerial(0, 0, 1) 
    End If 

    xRng.Value <= 0 Then 
        xRng.EntireRow.Interior.ColorIndex = 43 

        If xRng.Row =oDict(xRng.Offset(, -2).Value) Then 
            MsgBox xRng.Offset(, -2).Value & " Committed time is over" 
        End If

        Set xRng = xRng.Offset(1) 'Move to next cell in colum 

        If xRng.Value = vbNullString Then 
            MsgBox "All tasks are Over and CR is ready for the deployment" 
            Exit Sub 
        End If 
    End If 

    Call Timer 
End Sub

Sub PopDict() 
    Dim lRow As Long 

    lRow = 2 
    Do Until ActiveSheet.Cells(lRow, 2).Value = vbNullString
        oDict(ActiveSheet.Cells(lRow, 2).Value) = lRow 
        lRow = lRow + 1 
    Loop 
End Sub
