I am creating a spreadsheet that a user will fill in specific cells with data/text.
the whole sheet will be locked to prevent one from changing things.
i want as the first cell B4 to always be unlocked and has data entered in, this then unlocks cell B5 for data entry. this will continue on for many more cells.
here is what i have done so far.....
Private Sub Worksheet_Change(ByVal Target As Range)
If IsNumeric(Range("B4:F4")) = True Then
Range("B5").Locked = False
End If
End Sub
So... I made an attempt to help you.
Private Sub Worksheet_Change(ByVal target As Range)
Const inputrange As String = "B4:F4"
Const lockrange As String = "B5:F5"
Const lockedworksheet As String = "Tabelle2"
Set insect = Application.Intersect(target, Range(lockrange))
If Not (insect Is Nothing) Then Exit Sub
Worksheets(lockedworksheet).Unprotect
Range(inputrange).Locked = False
Range(lockrange).Locked = True
For Each cell In Range(inputrange)
If IsNumeric(cell.Value) And cell.Value <> 0 Then _
Cells(cell.Row + 1, cell.Column).Locked = False Else _
Cells(cell.Row + 1, cell.Column).Value = ""
Next cell
Worksheets(lockedworksheet).Protect
End Sub
If you need an explanation, just ask.

I need to ensure that the user types in an integer with length (blank) in any cell of a certain column. If the user inputs a number that is not length (blank), the Excel freezes the user at that cell and prompts to re-enter until integer length (blank) has been inputted or cancel is hit.
I currently have most of the things I request working. However, my issue is that Excel doesn't recognize length errors until I move away from the cell and come back to it.
For example (using 3 as desired length):
If i am currently on Cell B12 and type in 15646, which is not length 3, I can still click enter and it will move to Cell B13, which I want to prevent. But if I move up to B12 again from B13, the length error is seen and Excel prompts me to input integer with correct length until its fixed.
For now, the length error is only being recognized when I come back to cell. I need it to recognize as soon as I hit enter and prevent from moving on to next cell.
Sub InputNum()
row = ActiveCell.row
col = ActiveCell.Column
If col = 2 And ActiveCell.Value <> "" Then
Dim lotTextLen As Integer
lotTextLen = Len(ActiveCell.Value)
'checks to ensure the number put in is 3 characters long
'requests an input number to be put in
If lotTextLen <> 3 Then
lotData = InputBox("Invalid Entry Length. Scan in Lot #")
If Len(lotData) <> 3 Then
'error message
Result = MsgBox("Invalid Lot # Inputed. Must be 3 Characters. Try Again?", vbOKCancel)
'if cancel is clicked, input number is made blank and sub is exited
If Result <> vbOK Then
ActiveCell.Value = ""
'if ok is clicked to try again, recurses to beginning of code again
Else
InputNum
End If
Else
ActiveCell.Value = lotData
End If
End If
End If
End Sub
InputNum is being called in the Sheet1
Public Sub Worksheet_SelectionChange(ByVal Target As Range)
If Not Application.Intersect(Target, Range("B:C")) Is Nothing Then
InputNum
End If
End Sub
In the sheet object place the following
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Me.Columns(2)) Is Nothing Then
Application.EnableEvents = False
InputNum Target
Application.EnableEvents = True
End If
End Sub
Then use this in a standard module
Public Sub InputNum(Target As Range)
Dim IoTData As String
Dim Result As String
Dim isCancel As Boolean
Do While Len(Target.Value2) <> 3
IoTData = InputBox("Invalid Entry Length. Scan in Lot #")
If Len(IoTData) = 3 Then
Target.Value2 = IoTData
Else
If IoTData <> vbNullString Then
' error message
Result = MsgBox("Invalid Lot # Inputed. Must be 3 Characters. Try Again?", vbOKCancel)
If Result <> vbOK Then isCancel = True
Else
isCancel = True
End If
End If
If isCancel Then
Target.Value2 = vbNullString
Exit Do
End If
Loop
End Sub
By placing your code in a loop it will keep pestering the user for the right length until either they enter the right format or they press cancel in which instance the cell will be cleared of it's input.
You can also add And IsNumeric(IoTData) to your If statement to test that a number has been entered.
Replace
If Len(IoTData) = 3 Then
With
If Len(IoTData) = 3 And IsNumeric(IoTData) Then
Option Explicit
Dim add As String
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Range("B:C")) Is Nothing And Target.Count = 1 Then
If Len(Target.Value) <> 3 Then
MsgBox "Invalid entry in cell with address " & add
Application.EnableEvents = False
Target.Activate
'Enter more code
Application.EnableEvents = True
End If
End If
End Sub
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Not Intersect(Target, Range("B:C")) Is Nothing And Target.Count = 1 Then
add = Target.Address
End If
End Sub
I have a large workbook and am trying to increase performance.
Is it possible/viable to store my formulas in some sort of list contained within the code rather than in the cells on the spreadsheet?
Variable SelectedRow = the currently selected row
For example:
ColumnBFormula = A(SelectedRow) + 1
ColumnCFormula = A(SelectedRow) + 2
If the user enters 4 in cell A3, then the macro writes formulas above ONLY in empty cells B3 and C3, then converts to values. The rest of the spreadsheet remains unchanged (should only have values everywhere).
Then the user enters a 6 in cell A4 and the spreadsheet writes the formulas to empty cells B4 and C4, calculates then converts to values.
Thanks
Try:
Private Sub Worksheet_Change(ByVal Target As Range)
Dim Lastrow As Long
'Refer to Sheet1
With ThisWorkbook.Worksheets("Sheet1")
'Check if Column A affected
If Not Intersect(Target, Range("A:A")) Is Nothing And IsNumeric(Target) Then
'Disable event to avoid event trigger
Application.EnableEvents = False
Target.Offset(0, 1).Value = Target + 1
Target.Offset(0, 2).Value = Target + 2
'Enable event
Application.EnableEvents = True
End If
End With
End Sub
Instructions:
Enable Events:
Given you know what you want the code to do, you could do this without entering formulas.
In the VBA editor, add this code into the "ThisWorkbook" object ...
Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Target As Range)
Dim objCell As Range
Application.EnableEvents = False
For Each objCell In Target.Cells
If objCell.Column = 1 Then
If objCell.Value = "" Then
objCell.Offset(0, 1) = ""
objCell.Offset(0, 2) = ""
Else
objCell.Offset(0, 1) = objCell.Value + 1
objCell.Offset(0, 2) = objCell.Value + 2
End If
End If
Next
Application.EnableEvents = True
End Sub
Hopefully that works for you.
FYI - You'll need to add the relevant error checking for values if not numeric etc, it will need to be improved.
I found the attached when looking for how to due an event change to correct user data based on the values in two columns. I'm not a programmer, so I may have butchered the code as I combined two different solutions together.
Right now, it's working exactly as I want it to. Changing the offset cell value forces Excel to replace the target value with what I've specified. What I'm looking to achieve (and am not sure is possible), is to reverse the code. Basically, I want to change the offset cell, if the values are entered in the opposite order. The code will change the cell value to "Beta" if a user enters "Bravo" in column A, and then "Gamma" in column C.
What I'm trying to achieve is that if the user enters "Bravo" in column A second, that Excel still sees the combination of these cells and still replaces the value with "Beta". I know this is additional code, but I couldn't find anything to support replacing cell when the target cell isn't the value being updated.
Thanks in advance!
Dim oldCellAddress As String
Dim oldCellValue As String
Private Sub Worksheet_Change(ByVal Target As Range)
oldCellValue = "Bravo"
If Target = "Bravo" And Target.Offset(0, -2) = "Gamma" Then
Target.Value = "Beta"
Application.EnableEvents = True
End If
End Sub
This may meet your needs:
Private Sub Worksheet_Change(ByVal Target As Range)
Dim colnum As Long, v As Variant
colnum = Target.Column
v = Target.Value
If colnum = 1 Then
If v = "Bravo" And Target.Offset(0, 2) = "Gamma" Then
Application.EnableEvents = False
Target.Value = "Beta"
Application.EnableEvents = True
End If
Exit Sub
End If
If colnum = 3 And v = "Gamma" And Target.Offset(0, -2) = "Bravo" Then
Application.EnableEvents = False
Target.Offset(0, -2).Value = "Beta"
Application.EnableEvents = True
End If
End Sub
For example if the user puts Bravo in cell A1 and C1 already contained Gamma, the code puts Beta in A1 (the code corrects the A1 entry).If the user puts Gamma in cell C1 and cell A1 already contained Bravo, the code corrects A1.
There are two possible scenarios like below...
Scenario 1:
If ANY CELL on the sheet is changed, the following code will check the content of column A and C in the corresponding row and change the content of the Target Cell.
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.CountLarge > 1 Then Exit Sub
Dim r As Long
r = Target.Row
On Error GoTo Skip:
Application.EnableEvents = False
If Cells(r, "A") = "Bravo" And Cells(r, "C") = "Gamma" Then
Target.Value = "Beta"
End If
Skip:
Application.EnableEvents = True
End Sub
Scenario 1:
If a cell in column D is changed, the change event will be triggered and check the content in column A and C in the corresponding row and change the Target Cell in Column D.
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.CountLarge > 1 Then Exit Sub
Dim r As Long
On Error GoTo Skip:
'The below line ensures that the sheet change event will be triggered when a cell in colunm D is changed
'Change it as per your requirement.
If Not Intersect(Target, Range("D:D")) Is Nothing Then
Application.EnableEvents = False
r = Target.Row
If Cells(r, "A") = "Bravo" And Cells(r, "C") = "Gamma" Then
Target.Value = "Beta"
End If
End If
Skip:
Application.EnableEvents = True
End Sub
I am currently trying to add a script into excel. excuse my terminology, I am not that hot with programming!
I do all of my accounting on excel 2003, and I would like to be able to add the value of say cells f6 to f27 to the cells e6 to e27, respectively. The thing is, I want the value of the "f" column to reset every time.
So far I have found this code, which works if I copy and paste it into VBA. but it only allows me to use it on one row:
Private Sub Worksheet_Change(ByVal Target As Range)
Application.EnableEvents = False
If Target.Address = Range("f7").Address Then
Range("e7") = Range("e7") + Range("f7")
Range("f7").ClearContents
End If
Application.EnableEvents = True
End Sub
would somebody be kind enough to explain how I can edit this to do the same through all of my desired cells? I have tried adding Range("f7",[f8],[f9] etc.. but i am really beyond my knowledge.
First, you need to define the range which is supposed to be "caught"; that is, define the range you want to track for changes. I found an example here. Then, simply add the values to the other cell:
Private Sub Worksheet_Change(ByVal Target as Range)
Dim r as Range ' The range you'll track for changes
Set r = Range("F2:F27")
' If the changed cell is not in the tracked range, then exit the procedure
' (in other words, if the intersection between target and r is empty)
If Intersect(Target, r) Is Nothing Then
Exit Sub
Else
' Now, if the changed cell is in the range, then update the required value:
Cells(Target.Row, 5).Value = Cells(Target.Row, 5).Value + Target.Value
' ----------------^
' Column 5 =
' column "E"
' Clear the changed cell
Target.ClearContents
End if
End Sub
Hope this helps
Try this
Private Sub Worksheet_Change(ByVal Target As Range)
On Error GoTo ErrHandler
Application.ScreenUpdating = False
Application.EnableEvents = False
If Intersect(Target, Range("B1:B5,F6:F27")) Then 'U can define any other range
Target.Offset(0, -1) = Target.Offset(0, -1).Value + Target.Value ' Target.Offset(0,-1) refer to cell one column before the changed cell column.
'OR: Cells(Target.row, 5) = Cells(Target.row, 5).Value + Target.Value ' Where the 5 refer to column E
Target.ClearContents
End If
ErrHandler:
Application.EnableEvents = True
Application.ScreenUpdating = True
End Sub
How can I run a VBA function each time a cell gets its value changed by a formula?
I've managed to run code when a cell gets its value changed by the user, but it doesn't work when the value is changed due to a formula referencing another cell.
If I have a formula in cell A1 (e.g. = B1 * C1) and I want to run some VBA code each time A1 changes due to updates to either cell B1 or C1 then I can use the following:
Private Sub Worksheet_Calculate()
Dim target As Range
Set target = Range("A1")
If Not Intersect(target, Range("A1")) Is Nothing Then
//Run my VBA code
End If
End Sub
Update
As far as I know the problem with Worksheet_Calculate is that it fires for all cells containing formulae on the spreadsheet and you cannot determine which cell has been re-calculated (i.e. Worksheet_Calculate does not provide a Target object)
To get around this, if you have a bunch of formulas in column A and you want to identify which one has updated and add a comment to that specific cell then I think the following code will achieve that:
Private Sub Worksheet_Change(ByVal Target As Range)
Dim updatedCell As Range
Set updatedCell = Range(Target.Dependents.Address)
If Not Intersect(updatedCell, Range("A:A")) Is Nothing Then
updatedCell.AddComment ("My Comments")
End If
End Sub
To explain, for a formula to update, one of the input cells into that formula must change e.g. if formula in A1 is =B1 * C1 then either B1 or C1 must change to update A1.
We can use the Worksheet_Change event to detect a cell change on the s/sheet and then use Excel's auditing functionality to trace the dependents e.g. cell A1 is dependent on both B1 and C1 and, in this instance, the code Target.Dependents.Address would return $A$1 for any change to B1 or C1.
Given this, all we now need to do is to check if the dependent address is in column A (using Intersect). If it is in Column A we can then add comments to the appropriate cell.
Note that this only works for adding comments once only into a cell. If you want to continue to overwrite comments in the same cell you would need to modify the code to check for the existance of comments first and then delete as required.
The code you used does not work because the cell changing is not the cell with the formula but the cell... being changed :)
Here is what you should add to the worksheet's module:
(Updated: The line "Set rDependents = Target.Dependents" will raise an Error if there are no dependents. This update takes care of this.)
Private Sub Worksheet_Change(ByVal Target As Range)
Dim rDependents As Range
On Error Resume Next
Set rDependents = Target.Dependents
If Err.Number > 0 Then
Exit Sub
End If
' If the cell with the formula is "F160", for example...
If Not Application.Intersect(rDependents, Range("F160")) Is Nothing Then
Call abc
End If
End Sub
Private Sub abc()
MsgBox """abc()"" is running now"
End Sub
You can expand this if there are many dependent cells by setting up an array of cell addresses in question. Then you would test for each address in the array (you can use any looping structure for this) and run a desired subroutine corresponding to the changed cell (use SELECT CASE...) for this.
Here is another way using classes. The class can store cell Initial value and cell address. On calculate event it will compare the address current value with the stored initial value. Example below is made to listen to one cell only ("A2"), but you can initiate listening to more cells in the module or change the class to work with wider ranges.
Class module called "Class1":
Public WithEvents MySheet As Worksheet
Public MyRange As Range
Public MyIniVal As Variant
Public Sub Initialize_MySheet(Sh As Worksheet, Ran As Range)
Set MySheet = Sh
Set MyRange = Ran
MyIniVal = Ran.Value
End Sub
Private Sub MySheet_Calculate()
If MyRange.Value <> MyIniVal Then
Debug.Print MyRange.Address & " was changed from " & MyIniVal & " to " & MyRange.Value
StartClass
End If
End Sub
Initialize the class in normall module.
Dim MyClass As Class1
Sub StartClass()
Set MyClass = Nothing
Set MyClass = New Class1
MyClass.Initialize_MySheet ActiveSheet, Range("A2")
End Sub
Here is my code:
I know it looks terrible, but it works!
Of course there are solutions which are much better.
Description of the code:
When the Workbook opens, the value of the cells B15 till N15 are saved in the variable PrevValb till PrevValn. If a Worksheet_Calculate() event occurs, the previous values are compared with the actual values of the cells. If there is a change of the value, the cell is marked with red color. This code could be written with functions, so that he is much shorter and easier to read.
There's a color-reset-button (Seenchanges), which resets the color to the previous color.
Workbook:
Private Sub Workbook_Open()
PrevValb = Tabelle1.Range("B15").Value
PrevValc = Tabelle1.Range("C15").Value
PrevVald = Tabelle1.Range("D15").Value
PrevVale = Tabelle1.Range("E15").Value
PrevValf = Tabelle1.Range("F15").Value
PrevValg = Tabelle1.Range("G15").Value
PrevValh = Tabelle1.Range("H15").Value
