I have a range of values in a column which I am targeting.
Once any of the values in that range changes, it is supposed to call a macro.
The macro I am calling works but my change event is not getting recognized. Is there something wrong with my code?
My change even macro is located on the sheet where the change event is happening:
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = "$H$5:$H$32" Then
Call SetAxes
End If
End Sub
Do I need to be more specific with the range address?
Target.Address = "$H$5:$H$32" will only be True if that entire range changes at once.
To trap changes to one or more cells within that range, use Application.Intersect like this:
If Not Application.Intersect(Target, Range("$H$5:$H$32")) Is Nothing Then
I simply used worksheet_calculate and called the function when anything changes on the worksheet.
All the macro it is calling does is set the axes, so I don't mind if it runs repeatedly.
Private Sub Worksheet_Calculate()
Call SetAxes
End Sub
as a workaround, you could add a function:
Function FakeChange() As Integer
SetAxes
FakeChange = 0
End Function
and add behind your formulas in "$H$5:$H$32" +Fakechange()
like: ='your formula'+ FakeChange()
This function will be triggered when the results of your formulas are changed

How can I automatically execute an Excel macro each time a value in a particular cell changes?
Right now, my working code is:
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Range("H5")) Is Nothing Then Macro
End Sub
where "H5" is the particular cell being monitored and Macro is the name of the macro.
Is there a better way?
Your code looks pretty good.
Be careful, however, for your call to Range("H5") is a shortcut command to Application.Range("H5"), which is equivalent to Application.ActiveSheet.Range("H5"). This could be fine, if the only changes are user-changes -- which is the most typical -- but it is possible for the worksheet's cell values to change when it is not the active sheet via programmatic changes, e.g. VBA.
With this in mind, I would utilize Target.Worksheet.Range("H5"):
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Target.Worksheet.Range("H5")) Is Nothing Then Macro
End Sub
Or you can use Me.Range("H5"), if the event handler is on the code page for the worksheet in question (it usually is):
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Me.Range("H5")) Is Nothing Then Macro
End Sub
I spent a lot of time researching this and learning how it all works, after really messing up the event triggers. Since there was so much scattered info I decided to share what I have found to work all in one place, step by step as follows:
1) Open VBA Editor, under VBA Project (YourWorkBookName.xlsm) open Microsoft Excel Object and select the Sheet to which the change event will pertain.
2) The default code view is "General." From the drop-down list at the top middle, select "Worksheet."
3) Private Sub Worksheet_SelectionChange is already there as it should be, leave it alone. Copy/Paste Mike Rosenblum's code from above and change the .Range reference to the cell for which you are watching for a change (B3, in my case). Do not place your Macro yet, however (I removed the word "Macro" after "Then"):
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Me.Range("H5")) Is Nothing Then
End Sub
or from the drop-down list at the top left, select "Change" and in the space between Private Sub and End Sub, paste If Not Intersect(Target, Me.Range("H5")) Is Nothing Then
4) On the line after "Then" turn off events so that when you call your macro, it does not trigger events and try to run this Worksheet_Change again in a never ending cycle that crashes Excel and/or otherwise messes everything up:
Application.EnableEvents = False
5) Call your macro
Call YourMacroName
6) Turn events back on so the next change (and any/all other events) trigger:
Application.EnableEvents = True
7) End the If block and the Sub:
End If
End Sub
The entire code:
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Me.Range("B3")) Is Nothing Then
Application.EnableEvents = False
Call UpdateAndViewOnly
Application.EnableEvents = True
End If
End Sub
This takes turning events on/off out of the Modules which creates problems and simply lets the change trigger, turns off events, runs your macro and turns events back on.
Handle the Worksheet_Change event or the Workbook_SheetChange event.
The event handlers take an argument "Target As Range", so you can check if the range that's changing includes the cell you're interested in.
I prefer this way, not using a cell but a range
Dim cell_to_test As Range, cells_changed As Range
Set cells_changed = Target(1, 1)
Set cell_to_test = Range( RANGE_OF_CELLS_TO_DETECT )
If Not Intersect(cells_changed, cell_to_test) Is Nothing Then
Macro
End If
I have a cell which is linked to online stock database and updated frequently. I want to trigger a macro whenever the cell value is updated.
I believe this is similar to cell value change by a program or any external data update but above examples somehow do not work for me. I think the problem is because excel internal events are not triggered, but thats my guess.
I did the following,
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Target.Worksheets("Symbols").Range("$C$3")) Is Nothing Then
'Run Macro
End Sub

I did the following,
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Target.Worksheets("Symbols").Range("$C$3")) Is Nothing Then
'Run Macro
End Sub
I am trying to activate a macro by clicking in a cell.
Option Explicit
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Selection.Count = 1 Then
If Not Intersect(Target, Range("B37")) Is Nothing Then
Worksheets("DaysEditor").Activate
Sheets("DaysEditor").Columns("C:LY").Hidden = False
Sheets("DaysEditor").Columns("C:EX").Hidden = True
Sheets("DaysEditor").Range("A1").Select
End If
End If
End Sub
This code works on a cell that doesn't have a formula but will not work on cells with a formula in them.
A few minor tweaks I would change with your code. Firstly, if you are going to make multiple calls to a worksheet, I suggest that you either make a variable of it or use it within a With <obj> statement.
Worksheets() is essentially a function. Every time you use it it has to get the function's "value" - hence not the most efficient way of doing things.
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Target.Address = "$B$37:$C$37" Then
With Worksheets("DaysEditor")
.Columns("C:LY").Hidden = False
.Columns("C:EX").Hidden = True
.Activate
.Range("A1").Select
End With
End If
End Sub
Generally I advise against using the Activate method. But since you appear to actually want to be on the worksheet when the code runs then it's not a big deal here. Just remember that Activate is not necessary for the remainder of your code to function.
One last tweak is that I moved your Activate method after you hide/unhide the columns. Probably not a big deal either, but no need to watch the screen redraw unnecessarily.
Thanks to #K.Davis he helped me figure out that the problem was the that cell I was attaching this to was a merged cell and that was the problem. I changed the Selection.Count = 1 to Selection.Count = 2 and the code works perfectly!
I have the following worksheet function saved in the Sheet1 (DataInput) module of VBA
Sub worksheet_change(ByVal target As Range)
Set target = Range("F67")
If target.Value = "YES" Then
Call ThisWorkbook.Red_Macro_Text
End If
End Sub
This code calls the following code in ThisWorkbook
Public Sub Red_Macro_Text()
ThisWorkbook.Worksheets("DataInput").Range("B68").Value2 = ThisWorkbook.Worksheets("Text").Range("B3").Value2
End Sub
The purpose of the code is as follows:
The code uses an event trigger to watch for changes to worksheet ‘datainput’ cell F67.
Whenever the user selects ‘YES’ from a drop down menu in cell F67 it calls the subroutine in ThisWorkbook.
The code uses the range function to assign the value of 'text' worksheet B3 into 'datainput' worksheet B68 cell.
The trigger event does call the code and the content of B3 does get transferred to B68 however following this I then get the error message:
Run-time error ‘-2147417848 (80010108)’: Automation error The object
invoked has disconnected from its clients.
Please note I do not want to use an IF statement in excel to achieve this as I am trying to automate the process in VBA.
I have been searching for a solution to this problem for some time without success.
Does anyone know how to solve this problem as I have reached the limit of my understanding!
All help is appreciated
It doesn't make sense to Set target = Range("F67") because it is already retrieved as parameter ByVal target As Range
If you want to run the code only if F67 changes use the following instead:
Sub worksheet_change(ByVal Target As Range)
If Not Intersect(Target, Target.Parent.Range("F67")) Is Nothing Then
If Target.Parent.Range("F67").Value = "YES" Then
ThisWorkbook.Red_Macro_Text
End If
End If
End Sub
Note that Call is not needed to call a macro.
Try
Sub worksheet_change(ByVal Target As Range)
If Target.Address = Range("F67").Address Then
If Target.Value = "YES" Then
Call ThisWorkbook.Red_Macro_Text
End If
End If
End Sub
My purpose is to run a macro automatically on some 20 cells across my active worksheet whenever these are edited. Instead of having the same macro in place for every cell individually (makes the code very long and clumsy), I want to create a for loop which goes something like this:
for i="A10","A21","C3" ... etc
if target.address = "i" then
'execute macro
end if
I'm not quite sure how to do this... maybe another way would be a better option?
I'd really appreciate your help in the matter - thank you very much indeed.
You can use the Worksheet_Change event. Below is sample code. You need to put the code on the sheet code section
Private Sub Worksheet_Change(ByVal Target As Range)
Application.EnableEvents = False
Dim rng As Range
Set rng = Range("A1:B5")
' If there is change in this range
If Not Intersect(rng, Target) Is Nothing Then
MsgBox Target.Address & " range is edited"
' you can do manipulation here
End If
Application.EnableEvents = True
End Sub
You can use the Worksheet_Change event to capture the edits. See http://msdn.microsoft.com/en-us/library/office/ff839775.aspx.
The event body receives a Range object that represents the modified cells. You can then use Application.Intersect to determine if one of your target cells is in the modified range.
