箭头蓝色右泡 在Excel中插入倒数计时器


在Excel中,它不能倒计时,但你可以复制后面的VBA代码来帮助倒计时。

1。 选择一个单元格并将其格式化为时间格式,方法是右键单击单元格并选择 单元格格式,然后在对话框中单击 时间 并选择 13:30:55类型 列表,最后点击 OK 退出这个对话框。 看截图:

DOC-倒计时定时器1
DOC箭头
DOC-倒计时定时器2

2。 输入你想倒数到格式化单元格的时间。 看截图:

DOC-倒计时定时器5

3。 按 Alt + F11键 键打开 Microsoft Visual Basic for Applications 窗口。

4。 点击 插页 > 模块 然后将下面的VBA复制到新窗口中。

VBA:倒数计时器。

Dim gCount As Date
'Updateby20140925
Sub Timer()
    gCount = Now + TimeValue("00:00:01")
    Application.OnTime gCount, "ResetTime"
End Sub
Sub ResetTime()
Dim xRng As Range
Set xRng = Application.ActiveSheet.Range("E1")
xRng.Value = xRng.Value - TimeSerial(0, 0, 1)
If xRng.Value <= 0 Then
    MsgBox "Countdown complete."
    Exit Sub
End If
Call Timer
End Sub

小技巧:上述代码中的E1表示您在步骤2中键入的时间单元格。

5。 点击 按钮或按下 F5 运行倒数计时器。 现在时间倒计时了。

6。 倒计时完成后,弹出的对话框会提醒你。

    To stop the timer when you enter values into certain cells, you would use "Worksheet_Change", just include the range you want to listen to, you'll also need to create a global boolean so when you change anything within a cell range, it would set this boolean to false, so the next time it jumps into the "Time" sub procedure, it would instead check to see if the boolean is false, if you add "If TimerActive = False Then Exit Sub", at the beginning of the "Timer" sub, it will exit if that boolean returns false.




    Then inside "Worksheet_Change" you will want to add "TimerActive = True" at the beginning of the code, and something like the following code anywhere.

    If Not Intersect(Target, Range("B2:C57")) Is Nothing Then
    TimerActive = False
    End If

    This did not explain how the timer starts, does it start as soon as you open the sheet? I am looking to see if when I add a value of 100 to say cell "A1" a countdown timer will start on cell "G2"(maybe blink or turn red the last 30seconds to show urgency) and I want it to stop when I enter a value in a range of cells (B2:C57) or if not of no value was entered in those cells stop it by clicking on cell "A1" again or clicking right on the count down on cell "G2", I would also like to get the results on how long it took to enter a value on the range cells B2:C57 using the difference between the start time and the stop time on a cell collating to the range cells, like D2. Not sure if this all make sense but I would really like some help with it. The idea is when someone takes a call the mark down on the sheet the amount on the account and a countdown starts so they know how long they are on the call. If they take a payment on the amount on the account they would add it to another cell and the sheet will then add how long it took them to get that payment in yet another cell and the process will go down the line every time they take a new call. But only one cell would start the process every time.

    I already have an VBA that enters the users name and when the sheet is full they can click on a send button and it will email it to me with a subject and date and delete all the entires so they can start again the next day. I would love to just add the above right into this existing VBA if possible, that way I don't have to add another module. Can someone Help me with this, walk me step by step? My VBA or any program skills are very limited.

      You need to call the Sub procedure "Timer", this is usually done by calling it within another Sub/Function if you want the countdown to begin after you enter a value into cell "A1" and stop when you enter data into another range, then you need to listen for a change to those cells and create a boolean for the Timer sub procedure, so it knows when to stop, to do this create a "Worksheet_Change" sub procedure, this will listen to the worksheet for any changes, we then create a whitelist of ranges that will run our code.


      Sub Worksheet_Change(ByVal Target As Range)

      'Boolean default value
      Dim TimerActive As Boolean: TimerActive = True

      'This is where we call the Timer and get our value set in G2
      If Not Intersect(Target, Range("A1")) Is Nothing Then

      If IsEmpty(Target) Then TimerActive = False: Exit Sub

      On Error GoTo Errr:

      Dim i As Integer: i = Target

      Me.Range("G2").Value = i

      Call Timer

      ElseIf Not Intersect(Target, Range("B2:C57")) Is Nothing Then

      TimerActive = False

      If IsEmpty(Target) Then Exit Sub

      'Add more code here if needed

      End If

      'Error processing
      Exit Sub
      Errr:
      MsgBox "A1 Must be integer"

      End Sub

      I also included the ability to delete the value in A1, which will also stop the countdown, now, in the "Timer" sub procedure, at the beginning create an if statement to check whether or not our boolean "TimerActive" equals False, if it does then we need to Exit Sub. To change the Timers colour when counting down, you need to edit the "ResetTimer" sub procedure, and add an if statement, similar to the one that already exists, "If xRng <= 30", within that statement we add the colour we want to use "xRng.Font.Color = vbRed" you can also change the colour using "xRng.Font.Color = RGB(0,0,0)", do the same in the "Timer" procedure to reset the colour, do this before the boolean if statement, so that the colour always reverts back to its default, even when manually stopped.

      Hello Jose, I noticed the author did not respond to your comment, I've just recently discovered his post and thought I'd help you if you still need it. To trigger the timer, you need to call the sub procedure, so let us assume you have a sub in your worksheet that checks for any changes to cell A1, example:


      ########
      Sub Worksheet_Change(ByVal Target As Range)


      Dim rInt As Range: Set rInt = Intersect(Target, Range("A1"))


      If Not rInt Is Nothing Then


      On Error GoTo Err:
      Dim i As Integer: i = Me.Range("A1").Value


      If not IsEmpty(vCell) Then
      Call Timer <<< This is where you call the timer
      End If


      End If
      Exit Sub
      Err:
      MsgBox "Integer Only"
      End Sub
      ########


      The "Timer" Sub procedure is used to set the event, we basically want this to run every 1 second in the future which is why we use now + TimeValue("00:00:01"), if you wanted to update the timer in your cell every two seconds or every minute, you adjust the TimeValue accordingly.


      The "ResetTime" sub procedure is where we do all the heavy lifting, in this sub procedure, if you want to change the colour of the timer to red, once it reaches 30 seconds, you can do this by adding a simple if statement, just like the one that already exists within the procedure.


      If xRng.Value <= 30 Then
      xRng.Font.Color = vbRed
      End If
