I created a dropdown list like in this instruction. Now this cell needs to be triggered in my macro.
I already read some of the other entries to this topic, but in my VBA excel macro this code doesn't work:
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = "$B$2" Then
Call Macro1
End If
End Sub
Sub Macro1()
MsgBox "The value entered in Range B2 is " & Range("B2").Value
End Sub
If I change the value of the cell B2, this code doesn't get executed and no messagebox will be displayed.
I copied your code and put it into the sheet that I was editing and it works fine. If you try to put this code somewhere else, e.g. into ThisWorkbook, then it won't work because the eventhandler Worksheet_Change won't fire.
In addition to the above answer, if this is a merged cell and b2 isn't the first cell in the merge, this also won't work. However if that isn't the case and your code is in the right place, it's working fine
If you plan on changing any range values make sure and toggle EnableEvents. If you don't you risk recursively firing Worksheet_Change and crashing your project.
Here is a common design pattern
Turn off EnableEvents
Check if Target (cell that was changed) is in the range that you are validating
Pass Target as a parameter to another sub routine
Turn on EnableEvents
Private Sub Worksheet_Change(ByVal Target As Range)
Application.EnableEvents = False
If Not Intersect(Target, Range("B:B")) Is Nothing Then
Macro1 Target
End If
Application.EnableEvents = True
End Sub
Sub Macro1(Target As Range)
MsgBox "The value entered in Range " & Target.Address(True, True) & " is " & Target.value, vbInformation, "You Entered"
End Sub

I am having a problem with Excel crashing, when I run VBA code on an excel sheet.
I'm trying to add the following formula on worksheet change:
Private Sub Worksheet_Change(ByVal Target As Range)
Worksheets("testpage").Range("A1:A8").Formula = "=B1+C1"
End Sub
When this code is run i get a message saying "excel has encountered a problem and needs to close" and excel closes.
If I run the code in the Worksheet_Activate() procedure, it works fine and doesn't crash
Private Sub Worksheet_Activate()
Worksheets("testpage").Range("A1:A8").Formula = "=B1+C1"
End Sub
But I really need it to work in the Worksheet_Change() procedure.
Has anyone experienced similar crashes when using the Worksheet_Change() event and can anyone point in the right direction to fix this issue ?
I recommend this when using Worksheet_Change
You do not need the sheet name. In a Sheet Code Module, an unqualified Range reference refers to that sheet. That said, it is clearer to use the Me qualifier. If you are trying to use another sheet, then qualify the range reference with that sheet.
Whenever you are working with Worksheet_Change event, always switch Off events if you are writing data to any cell. This is required so that the code doesn't retrigger the Change event, and go into a possible endless loop
Whenever you are switching off events, use error handling to turn it back on, else if you get an error, the code will not run the next time.
Try this
Private Sub Worksheet_Change(ByVal Target As Range)
On Error GoTo Whoa
Application.EnableEvents = False
Me.Range("A1:A8").Formula = "=B1+C1"
Letscontinue:
Application.EnableEvents = True
Exit Sub
Whoa:
MsgBox Err.Description
Resume Letscontinue
End Sub
Few other things that you may want to know when working with this event.
If you want to ensure that the code doesn't run when more than one cell is changed then add a small check
Private Sub Worksheet_Change(ByVal Target As Range)
'~~> For Excel 2003
If Target.Cells.Count > 1 Then Exit Sub
'
'~~> Rest of code
'
End Sub
The CountLarge was introduced in Excel 2007 onward because Target.Cells.Count returns an Long value which can error out in Excel 2007 becuase of increased total cells count.
Private Sub Worksheet_Change(ByVal Target As Range)
'~~> For Excel 2007
If Target.Cells.CountLarge > 1 Then Exit Sub
'
'~~> Rest of code
'
End Sub
To work with all the cells that were changed use this code
Private Sub Worksheet_Change(ByVal Target As Range)
Dim aCell As Range
For Each aCell In Target.Cells
With aCell
'~~> Do Something
End With
Next
End Sub
To detect change in a particular cell, use Intersect. For example, if a change happens in Cell A1, then the below code will fire
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Me.Range("A1")) Is Nothing Then
MsgBox "Cell A1 was changed"
'~~> Your code here
End If
End Sub
To detect change in a particular set of range, use Intersect again. For example, if a change happens in range A1:A10, then the below code will fire
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Me.Range("A1:A10")) Is Nothing Then
MsgBox "one or more Cells in A1:A10 range was changed"
'~~> Your code here
End If
End Sub
Note: If you were getting an error earlier and you made the above changes and If your code is still not working then it is possible that the events have not been reset. In the Immediate Window, type Application.EnableEvents = True and press the ENTER key. This will reset it to True. If you do not see the Immediate Window, the press the shortcut key Ctl+G to launch the Immediate Window.
Excel was crashing, not the VBA function.
The events were not disabled and the call stack was filled by an infinite loop of OnChange events.
A little advice that helps finding this type of errors: set a breakpoint on the first line of the event, then execute it step by step pressing F8.
Also this solution is good:
Option Explicit
Private Busy As Boolean
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Busy Then
Busy = True
Range("A1:A8").Formula = "=B1+C1"
Busy = False
End If
End Sub

I want a msgbox to show up only once when formula result changes in my table range ("K2:K5"). Right now it shows twice.
In this range I have excel-formulas. Formula: H12*10
These formulas is refering to a dropdown-list (a list that I've created from "data validation" on the excel menu Data-tab).
The dropdown-list is located in cell H12.
The values in the dropdown is refering to range(D15:D17)
I've noticed though that the msgbox shows up once when I remove the dropdown and manualy type in values in H12.
Thankful for any help on this
Private Sub Worksheet_Calculate()
Dim Xrg As Range
Set Xrg = Range("K2:K5")
If Not Intersect(Xrg, Range("K2:K5")) Is Nothing Then
MsgBox "Hi"
End If
End Sub
I have also tried to add Application.enableEvents to the code but no success.
Private Sub Worksheet_Calculate()
Dim Xrg As Range
Set Xrg = Range("K2:K5")
Application.EnableEvents = False
If Not Intersect(Xrg, Range("K2:K5")) Is Nothing Then
MsgBox "Hi"
End If
Application.EnableEvents = True
End Sub
Your current code has no added value on a Worksheet_Calculate event due to comparing two exact same ranges and see if they intersect. That would always be the case. Your code would have the same effect as:
Private Sub Worksheet_Calculate()
MsgBox "Hi"
End Sub
Might you have more functions in your worksheet that could trigger this event unwanted outside range K2:K5, you should look into the Worksheet_Change event and return a messagebox when your referenced cell has changed value.
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = "$H$12" Then MsgBox "Hi"
End Sub
Choose either one, but don't use both cause you'll end up with two msgbox's
Is there a simple way to get Excel to automatically execute a macro whenever a cell is changed?
The cell in question would be in Worksheet("BigBoard").Range("D2")
What I thought would be a simple Google inquiry is proving to be more complicated - every sample involved intersects (whatever those are) or color formatting or any other number of things that appear to be irrelevant.
Yes, this is possible by using worksheet events:
In the Visual Basic Editor open the worksheet you're interested in (i.e. "BigBoard") by double clicking on the name of the worksheet in the tree at the top left. Place the following code in the module:
Private Sub Worksheet_Change(ByVal Target As Range)
If Intersect(Target, Me.Range("D2")) Is Nothing Then Exit Sub
Application.EnableEvents = False 'to prevent endless loop
On Error Goto Finalize 'to re-enable the events
MsgBox "You changed THE CELL!"
Finalize:
Application.EnableEvents = True
End Sub
Another option is
Private Sub Worksheet_Change(ByVal Target As Range)
IF Target.Address = "$D$2" Then
MsgBox("Cell D2 Has Changed.")
End If
End Sub
I believe this uses fewer resources than Intersect, which will be helpful if your worksheet changes a lot.
In an attempt to find a way to make the target cell for the intersect method a name table array, I stumbled across a simple way to run something when ANY cell or set of cells on a particular sheet changes. This code is placed in the worksheet module as well:
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Cells.Count > 0 Then
'mycode here
end if
end sub
In an attempt to spot a change somewhere in a particular column (here in "W", i.e. "23"), I modified Peter Alberts' answer to:
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Target.Column = 23 Then Exit Sub
Application.EnableEvents = False 'to prevent endless loop
On Error GoTo Finalize 'to re-enable the events
MsgBox "You changed a cell in column W, row " & Target.Row
MsgBox "You changed it to: " & Target.Value
Finalize:
Application.EnableEvents = True
End Sub
I was creating a form in which the user enters an email address used by another macro to email a specific cell group to the address entered. I patched together this simple code from several sites and my limited knowledge of VBA. This simply watches for one cell (In my case K22) to be updated and then kills any hyperlink in that cell.
Private Sub Worksheet_Change(ByVal Target As Range)
Dim KeyCells As Range
' The variable KeyCells contains the cells that will
' cause an alert when they are changed.
Set KeyCells = Range("K22")
If Not Application.Intersect(KeyCells, Range(Target.Address)) _
Is Nothing Then
Range("K22").Select
Selection.Hyperlinks.Delete
End If
End Sub
