I have simple macros for clearing cells on "Sheet1", which have drop down lists.
Sub reset1()
Range("D20:E21").ClearContents
Range("D8:E9").ClearContents
Range("D6:E7").ClearContents
End Sub
Sub reset2()
Range("D20:E21").ClearContents
Range("D8:E9").ClearContents
End Sub
Then I call these macros on "Sheet1" if the cell values change
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = "$D$4" Then
Call reset1
End If
If Target.Address = "$D$6" Then
Call reset2
End If
End Sub
This code is written on the "Sheet1".
Normally it works but sometimes reset1() doesn't work.
I should then save and reopen the excel or run the macro manually.
Should I better modify some codes?
First problem is that with Range("D20:E21") it is not clear in which worksheet that range should be. Always specify the worksheet like Worksheets("Sheet1").Range("D20:E21").
Second problem is that if you .ClearContents in a Worksheet_Change event this is a cell change and triggers another Worksheet_Change event and so on. So it is recommended to disable events Application.EnableEvents = False before changing cells in Worksheet_Change event.
Third problem is that if you test Target.Address = "$D$4" and you copy paste a range where D4 is included your code will not run even if your cell D4 changed. Therefore you always need to work with Intersect.

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
