EntireColumn.Hidden in Worksheet_Change() - excel

Using Excel 2010 I am editing an existing unprotected workbook and have created EntireColumn.Hidden and EntireRow.Hidden in commands in the Worksheet_Change() event to fire when a Data Validation cell is changed, but they don't work.
Private Sub Worksheet_Change(ByVal Target As Range)
With Application
.ScreenUpdating = False
.EnableEvents = False
End With
If Not Intersect(Target, Range("$C$2")) Is Nothing Then
Select Case Target.Value
Case "NO"
MsgBox "You just changed to HIDE" '<= Proves it fires
Range("$C$3").Value = "Invisible" '<= Does change cell
Columns("N:O").EntireColumn.Hidden = True '<= Doesn't hide
Case "YES"
MsgBox "You just changed to UNHIDE" '<= Proves it fires
Range("$C$3").Value = "Visible" '<= Does change cell
Columns("N:O").EntireColumn.Hidden = False '<= Doesn't unhide
End Select
End If
With Application
.ScreenUpdating = True
.EnableEvents = True
End With
End Sub
The event is firing as I have MsgBoxes to prove it. I can change cell values etc., but not the hiding/unhiding of the column/row.
I've copied my code to a new book and it works. So I copied it back into the original book but as a fresh, blank sheet and it works. It still doesn't work in the original, sizable sheet.
When I copied this into a simple macro it does work as required, hiding the correct columns, but at the push of a button:
Sub HideThem()
Columns("N:O").EntireColumn.Hidden = True '<= DOES work
End Sub
I need this to update automatically based on the value of a single cell. I've even tried to call this mini Sub from within the Worksheet_Change() event but that didn't work either.
Are there any known conflicts with other commands/events, on-sheet buttons, images, merged cells etc. that could be preventing the columns/rows from hiding?
I tried to use a CheckBox instead of a YES/NO Data Validation cell to fire the code (as that could be acceptable) but when I try to insert an ActiveX CheckBox it says Cannot insert object, even in a brand new blank book. Could this be a related problem?

I suppose you have a drop-down list in cell C3 with two items, viz "Visible" and "Invisible".
The following code will hide Columns N and O when you change the value of Range C3 from blank / "Visible" to "Invisible". Prior to this action, you will have to read the message and click OK. Changing from "Invisible" to "Visible" will present you with a message box. Click OK and see the hidden columns reveal themselves.
Private Sub Worksheet_Change(ByVal Target As Range)
If Range("C3") = "Invisible" Then
MsgBox ("You just changed to HIDE")
Columns(14).Hidden = True
Columns(15).Hidden = True
Else
If Range("C3") = "Visible" Then
MsgBox ("You just changed to UNHIDE")
Columns(14).Hidden = False
Columns(15).Hidden = False
End If
End If
End Sub

Multiple VBA targets for data validation on a single sheet

There are similar posts relating to my question, but I have struggled to adapt them to my problem. I currently have the following code which works just fine:
Option Explicit
Private Sub Worksheet_Change(ByVal Target As Range)
Application.EnableEvents = False
Application.ScreenUpdating = True
Set Target = Range("B4")
If Target.Value = "Yes" Then
Call DropDownListOn
Else
Call DropDownListOff
End If
Application.EnableEvents = True
End Sub
and the macros that are being called are:
Option Explicit
Sub DropDownListOn()
Sheet1.Activate
Sheet1.Range("A5").Value = "Plot default probability"
Sheet1.Range("B5").Validation.Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, Formula1:="Yes, No"
End Sub
and
Option Explicit
Sub DropDownListOff()
Sheet1.Range("A5").Value = ""
Sheet1.Range("B5").Validation.Delete
End Sub
Essentially what it does is as follows: Cell B4 is dropdown list. If "Yes" is chosen, then by calling the macro "DropDownListOn", it generates a new dropdown list in cell B5. This part works just fine; but, say, that once the dropdown list in cell B5 appears, I want to call another macro if B5 is chosen to be "Yes" (e.g., generating another dropdown list in cell B6). Given that only one target can be assigned to each sheet, this does not seem to be very straightforward. There seem to be suggestions for ways around this obstacle on Stackoverflow, but I struggle to adopt these to my own case. Any help and/or sample code will very much be appreciated.
Please, try the next updated event:
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address(0, 0) = "B4" Then
If Target.Value = "Yes" Then
Call DropDownListOn 'it let it creating the drop-down in "B5", TRIGGERING the change event
'but delete the charts ONE BY ONE!
Else
Application.EnableEvents = False
Call DropDownListOff 'the event is not triggered here.
'if you want to also clear "B6", you should place such a code line in the above Sub...
Application.EnableEvents = True
End If
ElseIf Target.Address(0, 0) = "B5" Then
Application.EnableEvents = False
'Place here the sub able to create the drop-down validation in "B6"
'it let it creating something else, but without triggering the event
Application.EnableEvents = Trud
End If
End Sub

In Excel, updating a formula seems to trigger an unrelated private sub on the same worksheet. How can I get this to stop?

I've created a drop down menu through data validation for workbook navigation. The following is a snippet of code I have for the drop down box to change worksheets in the workbook:
Private Sub Worksheet_Change(ByVal Target As Range)
On Error Resume Next
If Not (Application.Intersect(Range("J4"), Target) Is Nothing) Then _
ThisWorkbook.Sheets("Home").Visible = False
ThisWorkbook.Sheets(Target.Value).Activate
ThisWorkbook.Sheets(Target.Value).Visible = True
ThisWorkbook.Sheets("Imported Data").Visible = False
End Sub
The code is meant to hide all other worksheets that are accessible by the drop down list besides the one selected. I have about 10 tabs and this code has worked perfectly to achieve the basic goal of navigation. However, some pages have formulas and when you update data in the cells meant for calculations the workbook jumps to a random worksheet in the workbook that is not at all referenced in this sub.
Is there some way to have my worksheets not try to do anything with this sub unless the dropdown menu itself is changed?
Bonus (less important) Question: is there a way to make the drop box default to (blank) unless the menu itself is accessed?
Then _
The space followed by an underscore _ means that the current statement isn't finished yet but continues on the next line. Right now the last 3 lines will run whenever there is a change in the worksheet. Put the entire code in If-Endif.
Also avoid unnecessary use of On Error Resume Next. Use proper error handling.
You need to make the sheet visible before you activate it and not vice versa.
Try this
Private Sub Worksheet_Change(ByVal Target As Range)
On Error GoTo Whoa
If Not (Application.Intersect(Range("J4"), Target) Is Nothing) Then
ThisWorkbook.Sheets("Home").Visible = False
ThisWorkbook.Sheets(Target.Value).Visible = True
ThisWorkbook.Sheets(Target.Value).Activate
ThisWorkbook.Sheets("Imported Data").Visible = False
End If
Letscontinue:
Exit Sub
Whoa:
MsgBox Err.Description
Resume Letscontinue
End Sub
is there a way to make the drop box default to (blank) unless the menu itself is accessed?
If you have created it with Data Valdation then insert a blank value in the list.

Excel Determine if user hides/unhides columns

I've got worksheets that users will be hiding/unhiding columns on for printing purposes. Within those columns are certain cells which need to be copied to a visible area when those columns are hidden and the process reversed when they are not. The function works fine to detect the columns' visible status when the worksheet is activated. However it does not update at the time the column statuses are changed. I understand that the worksheet_calculate sub will detect changes in row visibility, but not columns, nor does it work in worksheet_change. Worksheet_SelectionChange seems buggy (selects more than selected even without code). Suggestions?
Public Function Copy_Hidden_ChargeCode_Descriptions(ByRef sht As String)
On Error GoTo ErrorHandler
Application.EnableEvents = False
If Worksheets(sht).Columns("C:G").Hidden = False Then
If Not IsEmpty(Worksheets(sht).Range("H4")) Then
Worksheets(sht).Range("H1").Cut Worksheets(sht).Range("C1")
Worksheets(sht).Range("H4:N9").Cut Worksheets(sht).Range("C4:H9")
End If
Else
If IsEmpty(Worksheets(sht).Range("H4")) Then
Worksheets(sht).Range("C1").Cut Worksheets(sht).Range("H1")
Worksheets(sht).Range("C4:H9").Cut Worksheets(sht).Range("H4:N9")
End If
End If
Application.EnableEvents = True
Exit Function
ErrorHandler:
Debug.Print Err.Number, Err.Description
End Function

disable editing in cells without protecting worksheet vba

I want to disable cell editing (direct typing into cell) but want to update that cell through code without protecting worksheet
Does anyone have any idea?
In the worksheet's code module:
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Range("A1:A10"), Target) Is Nothing Then
Application.EnableEvents = False
Target.ClearContents '// Assuming you want to keep it blank
Application.EnableEvents = True
End If
End Sub
Then in your code whenever you want to change a value, just disable events before hand:
'// Will be deleted
Range("A5").Value = "TEST"
'// Will not be deleted
Application.EnableEvents = False
Range("A5").Value = "TEST AGAIN"
Application.EnableEvents = True
I had a similar issue and found a workaround. For whatever reason I couldn't get my macros to run correctly with the sheets protected so what I did is as a code to Pop up a message box for any cells that I didn't want the user to change. Then I added "Application.DisplayAlerts = False" to the beginning of any codes that needed to modify those cells and reset the alerts back to True at the end of those codes.

Embeding Checkbox to a specific cells

I'm current working with VBA which is quite new for me. I'am trying to embeeded my checkbox into it specific cells so that each time the cells (row) is hidden, the checkbox will be hidden also with the cell.
below is the code I'm currently using to insert the Checkbox
ActiveSheet.CheckBoxes.Add(Cells(lRow, "A").Left, _
Cells(lRow, "A").Top, _
72, 17.25).Select
With Selection
.Caption = ""
.Value = xlOff
.LinkedCell = "C" & i
.Display3DShading = False
End With
Thanks.
AFAIK, I don't think so.
There's also no known Event to trap hiding and un-hiding of rows (again AFAIK).
The closest I can give is something like:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
On Error GoTo halt
Application.EnableEvents = False
Dim cb As CheckBox
Set cb = Me.Shapes("Check Box 1").OLEFormat.Object
cb.Top = Me.Range("cbrange").Top
cb.Visible = IIf(Me.Range("cbrange").Height = 0, False, True)
forward:
Application.EnableEvents = True
Exit Sub
halt:
MsgBox Err.Description
Resume forward
End Sub
This doesn't automatically hides the Checkbox, not until you select another range.
Take note that we used a named range which is the range that contains your Checkbox.
This is to make sure that the Checkbox stays with that cell even if the you insert rows. HTH somehow.
