create a countdown timer in excel 2010 using VBA (excel) - excel

I'm using Excel 2010, and want to create a countdown timer in excel. The code will be started and stopped by using buttons with macros attached to them. The problem occurs when the "start" button is pushed. The code above is utilizing Cell "B1" as the input spot, because I was just trying to get it to work, but every time I tried, it would always say:
"Cannot run the macro . The macro may not be available in this workbook or all macros may be disabled".
Yes I enabled all macros before putting this here. I want to be able to take user input, and to make that the time that the timer starts at instead of just using cell "B1".
'Macro for Starting the timer (attached to the start button)
Sub startTimer()
Application.OnTime Now + TimeValue("00:00:01"), "nextTick"
End Sub
'Macro for next second
Sub nextTick()
Sheet1.Range("B1").Value = Sheet1.Range("B1").Value - TimeValue("00:00:01")
startTimer
End Sub
'Macro for stopping the timer (attached to the end button)
Sub stopTimer()
Application.OnTime Now - TimeValue("00:00:01"), "nextTick", , False
End Sub

I modified your code very slightly and put it in a standard module:
Public Future As Double
Sub StartTimer()
Future = Now + TimeSerial(0, 0, 1)
Application.OnTime earliestTime:=Future, procedure:="nextTime", _
schedule:=True
End Sub
Sub nextTime()
Sheet1.Range("B1").Value = Sheet1.Range("B1").Value - TimeValue("00:00:01")
StartTimer
End Sub
Sub StopTimer()
On Error Resume Next
Application.OnTime earliestTime:=Future, _
procedure:="nextTime", schedule:=False
End Sub
Both StartTimer() and StopTimer() run just fine.

Workbook, which contains a clock, automatically reopens

I've got three Subs in Module: runClock, startClock and stopClock.
runClock is showing a clock that is updated every 5 seconds.
startClock is used to start the clock and is called from Sub Workbook_Open.
stopClock - is used to stop the clock and is called from Sub Workbook_BeforeClose.
However, when ever I close the workbook, it reopens automatically and the clock continues to run. I've checked the value of ClockOn and it's set to FALSE after the Workbook_BeforeClose is executed. I think that that issue has to do with Application.OnTime, but don't know how to fix it.
This Code is in Module:
Global ClockOn As Boolean
Sub runClock()
With Range("A1")
.Value = Now()
.NumberFormat = "hh:mm:ss"
If ClockOn = True Then
Application.OnTime Now + TimeSerial(0, 0, 5), "runClock"
End If
End With
End Sub
Sub startClock()
ClockOn = True
runClock
End Sub
Sub stopClock()
ClockOn = False
End Sub
This Code is in ThisWorkbook:
Private Sub Workbook_BeforeClose(Cancel As Boolean)
stopClock
ActiveWorkbook.Save
End Sub
Private Sub Workbook_Open()
startClock
End Sub
This seems to be happening because the times resulting from Application.OnTime are not the same. The initial call time should be saved as a variable and then referenced in the subs. See this solution.
https://www.ozgrid.com/forum/forum/help-forums/excel-general/131658-timer-reopens-workbook-when-closed
Found a solution in http://www.cpearson.com/excel/OnTime.aspx
I've changed my sub stopClock so now it includes the following code:
RunWhen = Now + timeserial(0, 0, 5)
Application.OnTime earliestTime:=RunWhen, Procedure:="startClock", Schedule:=False
This stops the clock from running and the workbook from reopening.
I don't know what caused it to reopen under the previous code, but at least now it's fine.

Clearing Excel AutoFilter using VBA

I am using this VBA code to refresh my entire workbook at specific time intervals. (thanks to this thread)
As you can see, it is currently set to refresh every 60 minutes.
Public RunWhen As Double
Public Const cRunIntervalMinutes = 60
Public Const cRunWhat = "Workbook_RefreshAll"
Sub StartTimer()
RunWhen = Now + TimeSerial(0, cRunIntervalMinutes, 0)
Application.OnTime earliesttime:=RunWhen, procedure:=cRunWhat, _
schedule:=True
End Sub
Sub StopTimer()
On Error Resume Next
Application.OnTime earliesttime:=RunWhen, _
procedure:=cRunWhat, schedule:=False
End Sub
Sub Workbook_RefreshAll()
Application.CalculateFullRebuild
ActiveWorkbook.RefreshAll
Call StartTimer
End Sub
The code works great, however there’s one thing I wish it could also do:
Any time the sheet is opened, and/or
Any time this VBA code executes the sheet refresh process
I would like the AutoFilter to be "Cleared" (not disabled or turned off) as in the screen grab below:
AutoFilter Clear
Thanks in advance for any assistance.
Cheers
This should do the trick. You may of course do it for one Sheet only, if you wish.
Sub Workbook_RefreshAll()
Dim sh As Worksheet
Application.CalculateFullRebuild
ActiveWorkbook.RefreshAll
For Each sh In ActiveWorkbook.Worksheets
If Not (sh.AutoFilter Is Nothing) Then sh.AutoFilter.ShowAllData
Next sh
Call StartTimer
End Sub

Type mis-match error in VBA for Excel countdown timer

I'm trying to create a simple timer in Excel using VBA code. However, I'm receiving a run-time error type mismatch in one of the applications.
Included in the timer are stop and start buttons. All code below.
The error occurs in this line:
Sheet1.Range("B1").Value = Sheet1.Range("B1").Value - TimeValue("00:00:01")
The error is type mismatch variant\string vs variant\integer.
The code is exactly what is shown on an youtube video. In the video it worked just fine.
https://www.youtube.com/watch?v=sbJeGG_Xv8M
Here is the code for the buttons and the routines.
Can someone please advise a fix? I'd be very appreciative.
Thanks!
Private Sub CommandButton1_Click()
starttimer
End Sub
Private Sub CommandButton2_Click()
stoptimer
End Sub
Sub starttimer()
Application.OnTime Now + TimeValue("00:00:01"), "nexttick"
End Sub
Sub nexttick()
Sheet1.Range("B1").Value = Sheet1.Range("B1").Value - TimeValue("00:00:01")
starttimer
End Sub
Sub stoptimer()
Application.OnTime Now + TimeValue("00:00:01"), "nexttick", , False
End Sub
Sheet1.Range("B1").Value
Is returning a value that's most probably a string. You need to change the Format of the cell to the custom format at the beggining of the video.
Click the cell, press Ctrl + 1 -> Custom Format -> write "m:ss"

Excel Randbetween - Refresh without Shift-F9

I'm looking to have an excel worksheet automatically calculate a rand between function without having to hit shift f9 or calculate the workbook/worksheet.
I'm looking to do this in order to create some animated conditional formatting, but the rand between function won't update automatically even when auto calculate is turned on.
Place the following code in a standard module:
Public RunWhen As Double
Public Const cRunIntervalSeconds = 1
Public Const cRunWhat = "The_Sub"
Sub StartTimer()
RunWhen = Now + TimeSerial(0, 0, cRunIntervalSeconds)
Application.OnTime earliesttime:=RunWhen, procedure:=cRunWhat, _
schedule:=True
End Sub
Sub The_Sub()
Application.CalculateFullRebuild
StartTimer
End Sub
Sub StopTimer()
On Error Resume Next
Application.OnTime earliesttime:=RunWhen, _
procedure:=cRunWhat, schedule:=False
End Sub
This implements 1 second auto-re-calculation:
to begin, run StartTimer
to stop, run StopTimer
Adapted from Chip Pearson
So I ended up doing a VB script to automatically do something to the spreadsheet using this example:
VBA Macro On Timer style to run code every set number of seconds, i.e. 120 seconds
This basically made all of the formulas update without the user doing anything (entering data or calculating).

How to make a timer like digital watch?

I was trying to make digital watch in excel. So, when I will open a workbook then in a cell, lets say in E3 cell will show time and it will continue in every second so that it looks like a digital watch. I can do it in Access as access Form has On Timer event where I can write code to show time in a Textbox. Is there any alternative way in excel. I have tried below codes. But the codes need to click manually on Button1. Can I make it automatic to run the Button1_Click() sub in every second?
Sub Button1_Click()
Application.OnTime Now(), "RunningTime"
End Sub
Sub RunningTime()
Range("E3") = Format(Now(), "hh:mm:ss")
End Sub
I have also tried Workbook_Open() method but it runs once when I open the file.
Private Sub Workbook_Open()
Application.OnTime Now(), "RunningTime"
End Sub
There is no direct way to achieve it but you can apply some tricks to do that. First put below codes to a Module.
Public Times As Boolean
Sub TimerRun()
If Not Times Then Exit Sub
Application.OnTime Now() + TimeValue("00:00:01"), "TimerRun"
Range("E3").Value = Range("E3").Value + TimeValue("00:00:01")
End Sub
Sub TimerStop()
Times = False
End Sub
Then copy below codes and paste in Workbook_Open() event.
Private Sub Workbook_Open()
Range("E3").Value = Format(Now(), "HH:MM:SS")
Times = True
TimerRun
End Sub
If you want to make start or stop button so that you can start/stop timer manually by clicking on a button then put a form control command button and then assign TimerRun sub to start and assign TimerStop to stop timer.
