Preventing Rows from being hidden based on cells not empty - excel

I am needing to prevent a range of rows from being hidden if any of the rows have text in cells in D column.
Private Sub Worksheet_Change(ByVal Target As Range)
Set rRng = Sheet1.Range("D35, D36, D37, D38, D39, D40")
If Target.Row >= 34 And Target.Row <= 40 Then
If IsEmpty("rRng.value") Then
Range("D35:D40").EntireRow.Hidden = False
Else: Range("D35:D40").EntireRow.Hidden = (Range("D34").Value = "")
End If
End If
End Sub

You might need to trigger your hide/unhide from the calculate event too so that any formulas/vba that changes the values also triggers and update. (Im not sure what the intended result is, so the code below isn't a dropin replacement)
Private Sub Worksheet_Calculate()
HideRows
End Sub
Private Sub Worksheet_Change(ByVal Target As Range)
HideRows
End Sub
Public Sub HideRows()
Dim R As Range: Set R = Sheet1.Range("D35:D40")
If Excel.WorksheetFunction.CountA(R) > 0 Then
R.EntireRow.Hidden = False
Else
R.EntireRow.Hidden = True
End If
End Sub
Sub SetAValue()
Sheet1.Range("D35").Value = "show"
End Sub

Combine VBA Codes to Hide Multiple Rows

I'd like to combine the two Hide Row Codes, please help!
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Sheets("Re-Hire Questionnaire").Protect Password:="Testing2022!", UserInterFaceOnly:=True
If Range("B12").Value = False Then
Rows("9:11").EntireRow.Hidden = True
Else
Rows("9:11").EntireRow.Hidden = False
End If
End Sub

Rows("16:16").EntireRow.Hidden = False
End If
End Sub
Tried to place them underneath each other but didn't work. I'm a novice btw lol
A Worksheet Selection Change: Hide Rows
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Target.Cells.CountLarge > 1 Then Exit Sub
Dim TargetCells: TargetCells = Array("B12", "B19")

Dim tCell As Range, hRows As Range, n As Long, WasSelected As Boolean
For n = LBound(TargetCells) To UBound(TargetCells)
Set tCell = Me.Range(TargetCells(n))
If Not Intersect(tCell, Target) Is Nothing Then
Set hRows = Me.Rows(HideRows(n))
hRows.EntireRow.Hidden = tCell.Value = False
WasSelected = True
End If
Next n
If WasSelected Then
Me.Parent.Sheets("Re-Hire Questionnaire").Protect _
Password:="Testing2022!", UserInterFaceOnly:=True

Copy Cell to another column on change

I need to copy the contents of a cell in a particular column to another corresponding column on change so the old value is moved. Only wants to work for a particular column.
Private sub Worksheet_Change(ByVal Target As Range)
if Target.Range("L:L") then
'set I cell value = to original L cell value
ActiveCell.Offset(0,-3).Value = ActiveCell.Value
End If
End Sub
This code should do what you want. Please take note of the comments which explain some limitations I have imposed on the action of this procedure. The rule to follow is to not give it more power than it needs to do the job you want it to do.
Private Sub Worksheet_Change(ByVal Target As Range)
' 027
Dim Rng As Range
' don't react if the changed cell is in row 1 or
' if it is more than 1 row below the end of column L
Set Rng = Range(Cells(2, "L"), Cells(Rows.Count, "L").End(xlUp).Offset(1))
If Not Application.Intersect(Target, Rng) Is Nothing Then
With Target
' skip if more than 1 cell was changed
' meaning, exclude paste actions
If .Cells.CountLarge = 1 Then
.Offset(0, -3).Value = .Value
End If
End With
End If
End Sub
This will save the previous value in column I:
Private Sub Worksheet_Change(ByVal Target As Range)
Dim v As Variant
If Target.Count > 1 Then Exit Sub
If Intersect(Range("L:L"), Target) Is Nothing Then Exit Sub
With Application
v = Target.Value
.EnableEvents = False
.Undo
Target.Offset(0, -3).Value = Target.Value
Target.Value = v
.EnableEvents = True
End With
End Sub
EDIT#1:
To update L without triggering the event, use something like:
Sub ScriptThatUpdatesColumn_L()
Application.EnableEvents = False
Range("L5").Value = "just me"
Application.EnableEvents = True
End Sub

Protect cell depending on other cell's value

I have an Excel spreadsheet where I want to protect cells in column I if the respective cell of column H <> "yes".
I found a code but it will protect all the cells of column I.
Option explicit
Sub unprotected
Me.unprotect password:= "abc"
End sub
Sub protect
Me.protect userinterfaceonly:= true ,password:= "abc"
End sub
Private Sub Worksheet_change(ByVal Target As Range)
Dim Crow as Long
Call Unprotected
xrow = Target.Row
If not (intersect(Target, range("H3:H1000")) is nothing then
Cells(xrow, "I").locked = (Ucase(trim(cells(xrow, "H").value))<>"yes")
End if
Call protect
End sub
Try this:
Option Explicit
Const PW As String = "abc" '<< use a constant for fixed/shared values
Private Sub Worksheet_change(ByVal Target As Range)
Dim rng As Range, c As Range
'find changed cells in range of interest
Set rng = Application.Intersect(Target, Me.Range("H3:H1000"))
If Not rng Is Nothing Then
UnprotectMe
'process each cell
For Each c In rng.Cells
Me.Cells.Cells(c.Row, "I").Locked = _
(UCase(Trim(Me.Cells(c.Row, "H").Value)) <> "YES")
Next c
ProtectMe
End If
End Sub
Sub UnprotectMe()
Me.Unprotect Password:=PW
End Sub
Sub ProtectMe()
Me.protect userinterfaceonly:=True, Password:=PW
End Sub

Limit macro to set a range for textbox

I am trying to link a range of cells to a text box, the only problem is if I edit the text box, it will write in any cell. I want to limit that ability to a specific range ("C4 to C11"). Here is my code:
Dim PreviousCell As Range
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Target.Column = 3 Then ActiveSheet.TextBox1.Text = Target
If Not PreviousCell Is Nothing Then
Debug.Print PreviousCell.Address
End If
Set PreviousCell = Target ' This needs to be the last line of code.
End Sub
Private Sub TextBox1_Change()
ActiveCell.Value = TextBox1
End Sub
Private Sub TextBox1_Change()
If ActiveCell.Column = 3 Then ActiveCell.Value = TextBox1
End Sub

How can I spread a sub to a multiple range of cells?

The purpose of this code is to update the date in a cell as a certain cell's contents are changed.
Since this was originally coded inside a sub, I now need to expand this code to a range of multiple cells. Ie. At this moment, the code only takes cell D4 and updates cell L4, I want to be able to drag this function down so it can reach a multiple range of cells; take D5 and update L5 etc.
Here's my code as the sub:
Dim oldValue
Public Sub Worksheet_SelectionChange(ByVal Target As Range)
oldValue = Target.Worksheet.Range("D4").Value
End Sub
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Target.Worksheet.Range("D4")) Is Nothing Then
If oldValue <> Target.Worksheet.Range("D4").Value Then
Target.Worksheet.Range("L4").Value = Date
End If
End If
End Sub
The problem here, is that I don't know how to properly expand my code to match a further selection of cells. Here's my attempt:
Dim oldValue
Public Sub Worksheet_SelectionChange(ByVal Target As Range)
oldValue = Target.Worksheet.Range("D4", "D21").Value
End Sub
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Target.Worksheet.Range("D4", "D21")) Is Nothing Then
If oldValue <> Target.Worksheet.Range("D4", "D21").Value Then
Target.Worksheet.Range("L4", "L21").Value = Date
End If
End If
End Sub
EDIT: The sub I have written only applies to one cell, I am trying to work out a way to have it spread out to a certain selection of cells. Ie. D4:D12 which updates the date in L4:L12 accordingly.
If anyone could help me, that would be greatly appreciated.
Try the following code:
Dim oldValue()
Public Sub Worksheet_SelectionChange(ByVal Target As Range)
oldValue = Me.Range("D4:D12").Value
End Sub
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Me.Range("D4:D12")) Is Nothing Then
Application.EnableEvents = False
Dim c As Range
For Each c In Intersect(Target, Me.Range("D4:D12"))
'Check value against what is stored in "oldValue" (row 4 is in position 1, row 5 in position 2, etc)
If oldValue(c.Row - 3, 1) <> c.Value Then
'Update value in column L (8 columns to the right of column D)
c.Offset(0, 8).Value = Date 'or possibly "= Now()" if you need the time of day that the cell was updated
End If
Next
Application.EnableEvents = True
End If
End Sub
Set up a hidden sheet to hold the old values.
Sub SetupMirrorValues()
With Worksheets.Add
.Name = "MirrorValues"
.visibilty = xlSheetVeryHidden
.Range("D4:D10,D12,D14:D20") = Worksheets("Sheet1").Range("D4:D10,D12,D14:D20")
End With
End Sub
In the Worksheet_Change event handler, you would check the Target cells that intersect with the range you want to monitor. If there are differences then you update the timestamp and the cell on the hidden sheet that corresponds to the changed cell.
Private Sub Worksheet_Change(ByVal Target As Range)
Application.EnableEvents = False
Application.ScreenUpdating = False
Dim cell As Range, DRange As Range
Set DRange = Range("D4:D10,D12,D14:D20")
If Not Intersect(DRange, Target) Is Nothing Then
For Each cell In Intersect(DRange, Target)
If cell.Value <> Worksheets("MirrorValues").Range(cell.Address) Then
cell.EntireRow.Cells(1, "L").Value = Now
Worksheets("MirrorValues").Range(cell.Address) = cell.Value
End If
Next
End If
Application.EnableEvents = True
Application.ScreenUpdating = False
End Sub
