He all I need help writing an If statement that will run a macro every time the value in cell D8 is over one. No idea where to start
Here you go...
Private Sub Worksheet_Change(ByVal Target As Range)
If Intersect(Target, Range("D1")) Is Nothing Then Exit Sub
If Not Range("D1").Value > 1 Then Exit Sub
MsgBox "D1 > 0"
End Sub
For more info on the _Change event:
http://msdn.microsoft.com/en-us/library/office/ff839775.aspx
It is a simple if statement.
If Range("D8").Value > 1 Then
'~~> Your code here
End If
You can put that in the Worksheet_Change event. I would also recommend reading this link which talks about Worksheet_Change
If the value in Range("D8") is changing because of a formula then you might have to use the _Calculate event. See this link for an example.

I read a lot of pages saying that, but none of them put the solution if the value change by an "if function" not by hand.
The code I get is that:
Private Sub Worksheet_Change(ByVal Target As Range)
If Intersect(Target, Me.Range("A18:A30")) Is Nothing Then Exit Sub
Application.EnableEvents = False 'to prevent endless loop
On Error GoTo Finalize 'to re-enable the events
MsgBox "You changed THE CELL!"
Finalize:
Application.EnableEvents = True
End Sub
It only works if I change the value by hand.
Thank you in advance.
Another solution; instead of triggering your function every time when your worksheet recalculates, add a function in a module:
Function DetectChange() As Integer
MsgBox "You changed THE CELL!"
DetectChange = 0
End Function
Assuming the outcome of your formula is numeric:(otherwise outcome of function must be a empty string and the "+" must be "&")
Add to your IF-formula at the end ...+Detectchange()
Now there will be a msgbox only when your formula is recalculated
Edit by Darren Bartrup-Cook:
I found this code gave worked when the formula recalculated. It didn't fire if I changed a cell that doesn't affect the cell it's entered to and it didn't fire using Calculate Now or Calculate Sheet.
It did occasionally fire for all formula that I used the function in, but that seemed to be when I was debugging - maybe further investigation needed.
Public Function DetectChange()
MsgBox "You changed cell " & Application.Caller.Address
End Function
e.g.:
=IF(A1=1,A2,A3) & DetectChange() entered in cell A4 displays the message "You changed cell $A$4" if cells A1, A2 or A3 is changed.
Write this in Sheet1 and run the TestMe sub:
Private Sub Worksheet_Change(ByVal Target As Range)
If Intersect(Target, Me.Range("A1:A30")) Is Nothing Then Exit Sub
Application.EnableEvents = False
On Error GoTo Finalize
MsgBox "You changed THE CELL!"
Finalize:
Application.EnableEvents = True
End Sub
Sub TestMe()
Range("A1") = 34
End Sub
It has worked quite ok on my PC.
If the cell is changed by a built-in Excel function, then the comment of #Vincent G states the correct answer:
Worksheet_Change event occurs when cells on the worksheet are changed by the user or by an external link. and This event does not occur when cells change during a recalculation. Use the Calculate event to trap a sheet recalculation.
If you want to track the calclulation event based on some changes at Range(A18:A30) this is a working solution:
Add a new Worksheet to your Workbook (Sheet2);
In the current Worksheet write the Calculate event:
Private Sub Worksheet_Calculate()
Dim cell As Range
For Each cell In Sheet2.Range("A18:A30")
If cell <> Sheet1.Range(cell.Address) Then
cell = Sheet1.Range(cell.Address)
End If
Next cell
End Sub
In the Sheet2 write an event, catching the changes.
As simple as #Vincent G says.
Private Sub Worksheet_Calculate()
Call YourFunction
End Sub
I have a problem with Worksheet_Change. When I target the cell Excel doesn't react at all even if I put an error in the code. I put the Worksheet_Change on the right sheet, so that's not the reason.
I simplified my code as much as I could and there is still no reaction.
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = "$c$2" Then
MsgBox "hi"
End If
End Sub
I think the event listener that you want to trigger is Worksheet_SelectionChange.
For Worksheet_Change to work, you need to type something in cell C3
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Me.Range("C2"), Target) Is Nothing Then
MsgBox "Great! Target is within the chosen range!"
End If
End Sub
This works. I always use the above structure.
Is there an object and/or function that can detect or represent a general change on a worksheet? Something similar to (for example) ComboBox1_Change() but could be applied to a whole worksheet. Almost something like Worksheet1_Change(). Any suggestions are welcome. Thanks.
The simplest would be to use the worksheet change event:
Private Sub Worksheet_Change(ByVal Target As Range)
MsgBox "Change Detected!"
End Sub
There are instances will this will throw you in to an infinite loop. Consider this code:
Private Sub Worksheet_Change(ByVal Target As Range)
Range("A1").Value = "Change"
End Sub
Set a breakpoint on the Range("A1") code and make a change somewhere else on the sheet and count how many time that breakpoint gets hit. When you get tired of hitting F5, stop the code and try this:
Private Sub Worksheet_Change(ByVal Target As Range)
Application.EnableEvents = False
Range("A1").Value = "Change"
Application.EnableEvents = True
End Sub
You'll see that the code only fires once. Which is probably what you're after.
It's very important that you have the Application.EnableEvents = True line in there, or else you'll get the appearance that your code isn't working (by default EnableEvents does not revert back to True at the end of the code).
I am working with Excel VBA and I have a macro that is fired everytime a specific cell is changed. That macro affects the value and properties of many cells on the worksheet, so I used
Private Sub Worksheet_Change(ByVal Target As Range)
Application.EnableEvents = False
[...] 'mycode
Application.EnableEvents = True
End Sub
At the beginning and end of the macro. Otherwise whenever I change the cell that fires the macro, the macro changes cell and thus fires itself over and over again.
I would like for the macro to be fired if I manually change a cell (without having to insert a command button that fires the macro or something similar)
Is that possible?
Thanks for the help
Private Sub Worksheet_Change(ByVal Target As Range)
If (Target.Column =4) Then
MsgBox ("mycell changed")
End If
End Sub
This basically says if the column change occurs in Index 4 (D) then msgbox.
if you didn't have the if statement the messgbox would occur anytime a change occurs to any cell in the worksheet.
I am trying to call a macro named "RE_environmental" when the cell named "RE_1" is changed (i.e. they mark a X in the cell). I've tried several different variations of codes including these two and nothing is happening:
[The first code does work if I use the exact cell location and not the named cell. --> $E$62]
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = "RE_1" Then
Call RE_environmental
End If
End Sub
AND
Private Sub Worksheet_Change(ByVal Target As Range)
If Range("Name").Select = "RE_1" Then
Call RE_environmental
End If
End Sub
--Thanks in Advanced and please let me know if you need more information.
Use your first answer but make this small change:
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = Range("RE_1").Address Then
Call RE_environmental
End If
End Sub
Simple syntax mistake!
Edit: To stop RE_environmental from running once the cell is empty, put the code from RE_environmental inside a do-while (not isempty(Range("RE_1"))) as long as RE_environmental is emptying "RE_1". The user won't be able to edit cells while RE_environmental is running.
If Target is always single-cell range, you can use this one:
If Target.Address = Range("RE_1").Address Then
Call RE_environmental
End If
If Target can be multicell range use this one:
If Not Intersect(Target, Range("RE_1")) Is Nothing Then
Call RE_environmental
End If
