Private Sub Worksheet_Change(ByVal Target As Range)
'Hvis du på noget tidspunkt tilføjer flere rows, så sig til.
Application.EnableEvents = False
If Not Intersect(Range("B27:B33"), Target) Is Nothing Then
Target.Offset(, 1).Formula = "=UDF_Now()"
End If
Application.EnableEvents = True
End Sub
I am using the following VBA code to execute my user defined function whenever a cell value in the Range("B27:B33") changes.
This works fine, as long as I am changing the cell values in the range manually. The issue is now that I want this macro to work for a given range that is made up by formulas. Whenever I change any of the precedents, a cell value of the range changes, but my macro does not execute.
I want this to work with formulas, so that the macro gets executed whenever I change a precedent and thus change the values of the cells within the range.
I hope this is useful explanation.
The Change Event code doesn't get triggered when the cell content is changed due to a formula.
If you want to trigger a event when the value is being changed by a formula, you may consider Worksheet_Calculate also along with change event code if that is also required.
I have a sheet where I daily change the stats of some rows and I have to know when the stats changed. To make my life easier, I found on the internet this VBA code:
Private Sub Worksheet_Change(ByVal Target As Range)
If Intersect(Target, Range("R1:R2000")) Is Nothing Then Exit Sub
Target.Offset(0, 1) = Date
End Sub
The code works wonderfully. Everytime I change de stats on column R, it update the date on column S.
The problem is that I change this stat in a table linked to an outside source (Oracle Database) and if I try to refresh the table, it change the entire content of the table to different dates. What I have to do now is, everytime I have to refresh the table, I just comment the entire VBA Code.
Is there anything I can change on the code so it doesn't update when I refresh the table?
Edit 1:
Sub RefreshOracleTable()
Application.EnableEvents = False
If Intersect(Target, Range("R1:R200000")) Is Nothing Then Exit Sub
Target.Offset(0, 1) = Date
ThisWorkbook.Sheets("wsTables").ListObjects("OracleTable").QueryTable.Refresh BackgroundQuery:=Application.EnableEvents = True
End Sub
Disable events, then refresh table
You can write a Sub, which you will use for refreshing the table. Before refresh you will disable excel events. Like so:
Sub RefreshOracleTable
Application.EnableEvents = False
'the refresh itself code something like
Thisworkbook.Sheets("wsTables").ListObjects("OracleTable").QueryTable.Refresh BackgroundQuery:=False
Application.EnableEvents = TRUE
End Sub

Consider using a Keyboard shortcut to manualy enter the current date. CTRL + ;
Explanation of current situation and proposed solution
I have been trying to work this out myself for the last few days and caught myself in a bit of a one step forward three steps back cycle. I've been reluctant to bother you thinking this would have been answered somewhere else before now.
The idea is that I have a spreadsheet that has criteria in rows with separate entries in rows; in row 6 it is the status of each column entry, which when changed to "Completed" I would like the column to be hidden.
I've been floundering around with Worksheet_Change and been able to hide specific columns, but not the active column.
Any help offered would be much appreciated and I'm sorry if this has been covered elsewhere, but I've not been able to successfully apply any examples out there.
Thanks.
Whenever you have to work with worksheet_change events, you have to consider a cycle for it, due to user may delete multiple data at the same time or do a copy paste, if you only consider "Target" It would give a debugger error.
Private Sub Worksheet_Change(ByVal Target As Range)
Dim ItemMultipleData As Range
For Each ItemMultipleData In Target 'handles multiple cells, paste, del, etc
'your code (instead of using "Target" change to ItemMultipleData. IE:
'If ItemMultipleData.Value = "Completed" Then
Next ItemMultipleData
End Sub
Here is a starting point. It only checks row # 6:
Private Sub Worksheet_Change(ByVal Target As Range)
Dim rng As Range
Set rng = Range("6:6")
If Intersect(Target, rng) Is Nothing Then Exit Sub
If Target.Count <> 1 Then Exit Sub
If Target.Value = "Completed" Then
Application.EnableEvents = False
Target.EntireColumn.Hidden = True
Application.EnableEvents = True
End If
End Sub
EDIT#1:
This approach assumes that only one cell at a time is being changed........that makes it easy to "find the active cell"
I am trying to detect if there are changes in a cell value, not particularly the cell contents. I have found multiple solutions to find out if a cell contents has changed, but it does not work when a cell is equal to another cell.
For example, I have cell A1 set to equal B1 and then B1 has a formula that calls in multiple other cells, so I am not able to go back to the beginning and determine whether the cell has changed from that. It needs to come directly from A1.
This is one of the examples I found on this site, but does not determine if the value of A1 has changed, just whether the contents has changed.
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Column = 1 Then
Cells(Target.Row, 3).Value = Date
End If
End Sub
The function application.volatile TRUE at the top of your sub will make your sub calculate each time any value in Excel changes. So then you need a global variable which stores the last-known value of your specified range, and any time the sub runs, start with an
If new_cell_value <> stored_global_variable then...
and close with
stored_global_variable = new_cell value'
End If

Is there a way to catch a click on a cell in VBA with Excel? I am not referring to the Worksheet_SelectionChange event, as that will not trigger multiple times if the cell is clicked multiple times. BeforeDoubleClick does not solve my problem either, as I do not want to require the user to double click that frequently.
My current solution does work with the SelectionChange event, but it appears to require the use of global variables and other suboptimal coding practices. It also seems prone to error.
Clearly, there is no perfect answer. However, if you want to allow the user to
select certain cells
allow them to change those cells,
and
trap each click,even repeated clicks
on the same cell,
then the easiest way seems to be to move the focus off the selected cell, so that clicking it will trigger a Select event.
One option is to move the focus as I suggested above, but this prevents cell editing. Another option is to extend the selection by one cell (left/right/up/down),because this permits editing of the original cell, but will trigger a Select event if that cell is clicked again on its own.
If you only wanted to trap selection of a single column of cells, you could insert a hidden column to the right, extend the selection to include the hidden cell to the right when the user clicked,and this gives you an editable cell which can be trapped every time it is clicked. The code is as follows
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
'prevent Select event triggering again when we extend the selection below
Application.EnableEvents = False
Target.Resize(1, 2).Select
Application.EnableEvents = True
End Sub
In order to trap repeated clicks on the same cell, you need to move the focus to a different cell, so that each time you click, you are in fact moving the selection.
The code below will select the top left cell visible on the screen, when you click on any cell. Obviously, it has the flaw that it won't trap a click on the top left cell, but that can be managed (eg by selecting the top right cell if the activecell is the top left).
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
'put your code here to process the selection, then..
ActiveWindow.VisibleRange.Cells(1, 1).Select
End Sub
SelectionChange is the event built into the Excel Object model for this. It should do exactly as you want, firing any time the user clicks anywhere...
I'm not sure that I understand your objections to global variables here, you would only need 1 if you use the Application.SelectionChange event. However, you wouldn't need any if you utilize the Workbook class code behind (to trap the Workbook.SelectionChange event) or the Worksheet class code behind (to trap the Worksheet.SelectionChange) event. (Unless your issue is the "global variable reset" problem in VBA, for which there is only one solution: error handling everywhere. Do not allow any unhandled errors, instead log them and/or "soft-report" an error as a message box to the user.)
You might also need to trap the Worksheet.Activate() and Worksheet.Deactivate() events (or the equivalent in the Workbook class) and/or the Workbook.Activate and Workbook.Deactivate() events so that you know when the user has switched worksheets and/or workbooks. The Window activate and deactivate events should make this approach complete. They could all call the same exact procedure, however, they all denote the same thing: the user changed the "focus", if you will.
If you don't like VBA, btw, you can do the same using VB.NET or C#.
[Edit: Dbb makes a very good point about the SelectionChange event not picking up a click when the user clicks within the currently selected cell. If you need to pick that up, then you would need to use subclassing.]
I don't think so. But you can create a shape object ( or wordart or something similiar ) hook Click event and place the object to position of the specified cell.
This has worked for me.....
Private Sub Worksheet_Change(ByVal Target As Range)
If Mid(Target.Address, 3, 1) = "$" And Mid(Target.Address, 2, 1) < "E" Then
' The logic in the if condition will filter for a specific cell or block of cells
Application.ScreenUpdating = False
'MsgBox "You just changed " & Target.Address
'all conditions are true .... DO THE FUNCTION NEEDED
Application.ScreenUpdating = True
End If
' if clicked cell is not in the range then do nothing (if condttion is not run)
End Sub
NOTE: this function in actual use recalculated a pivot table if a user added a item in a data range of A4 to D500. The there were protected and unprotected sections in the sheet so the actual check for the click is if the column is less that "E" The logic can get as complex as you want to include or exclude any number of areas
block1 = row > 3 and row < 5 and column column >"b" and < "d"
block2 = row > 7 and row < 12 and column column >"b" and < "d"
block3 = row > 10 and row < 15 and column column >"e" and < "g"
If block1 or block2 or block 3 then
do function .....
end if
I had a similar issue, and I fixed by running the macro "onTime", and by using some global variables to only run once the user has stopped clicking.
Public macroIsOnQueue As Boolean
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
macroIsOnQueue = False
Application.OnTime (Now() + TimeValue("00:00:02")), "addBordersOnRow"
macroIsOnQueue = True
End sub
Sub addBordersOnRow()
If macroIsOnQueue Then
macroIsOnQueue = False
' add code here
End if
End sub
This way, whenever the user changes selection within 2 seconds, the macroIsOnQueue variable is set to false, but the last time selection is changed, macroIsOnQueue is set to true, and the macro will run.
Hope this helps,
Have fun with VBA !!
Just a follow-up to dbb's accepted answer: Rather than adding the immediate cell on the right to the selection, why not select a cell way off the working range (i.e. a dummy cell that you know the user will never need). In the following code cell ZZ1 is the dummy cell
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Application.EnableEvents = False
Union(Target, Me.Range("ZZ1")).Select
Application.EnableEvents = True
' Respond to click/selection-change here
End Sub
