Capture Cell Value on left mouse single click in Excel VBA - vba

I need help in capturing the cell value on left mouse click. So when a user has done a single left mouse click in a particular cell then I need to capture that particular cell value (Value written in that cell) in the VBA code.
This value will then be passed on to the VBA code and the output will be different for click in different cells. I hope I was able to explain the purpose.
I have total of 10 cells where the left mouse click value is to be captured.

This code will check to see if multiple cells are selected at once then it checks to see if the cell is empty. If it is empty then it exits otherwise it stores the value is cell N1. You can change which cell the value gets stores at. If N1 has a value it goes to the next empty cell in column N.
Dim oval
Dim N As Long
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Target.Cells.Count < 2 Then
If Target = Empty Then
Exit Sub
End If
oval = Target.Value
MsgBox "The value saved is " + oval + "."
If Range("N1").Value = "" Then
N = 1
Else
N = Cells(Rows.Count, "N").End(xlUp).Row + 1
End If
Cells(N, "N").Value = oval
End If
End Sub

If you would settle for a double mouse click, you could try something like
Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)
MsgBox Target.Value
Cancel = True
End Sub

How about this? Just wrote it, it will not register a mouse click if you click where you could have reached with the keyboard
Enter Under Worksheet Code:
XXXXXXX
Option Explicit
Private prevTarget As Range
Private Sub Worksheet_Activate()
Set prevTarget = Selection
End Sub
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Dim wasMouseClick As Boolean
Dim ch1, ch2, ch3, ch4, ch5, ch6, ch7, ch8, ch9 As String
On Error Resume Next
ch1 = prevTarget.Offset(1, 0).Address
ch2 = prevTarget.Offset(-1, 0).Address
ch3 = prevTarget.Offset(0, 1).Address
ch4 = prevTarget.Offset(0, -1).Address
ch5 = prevTarget.End(xlDown).Address
ch6 = prevTarget.End(xlToLeft).Address
ch7 = prevTarget.End(xlToRight).Address
ch8 = prevTarget.End(xlUp).Address
On Error GoTo error_noPreTarget
If Not (Target.Address = ch1 Or _
Target.Address = ch2 Or _
Target.Address = ch3 Or _
Target.Address = ch4 Or _
Target.Address = ch5 Or _
Target.Address = ch6 Or _
Target.Address = ch7 Or _
Target.Address = ch8) Then
wasMouseClick = True
End If
Set prevTarget = ActiveCell
If wasMouseClick Then
Debug.Print wasMouseClick ' replace with what you want when wasMouseClick = True
End If
Exit Sub
error_noPreTarget:
Set prevTarget = Selection
End Sub

Ensure Cell Value Follows a Specified Character & Number Combination

Im new to vba I have a requirement where in I have restrict input to column A of a worksheet where user can only enter string in following format
'BATCH00_00' numbers can range from 0-99 I tried the below code but it does not work
Private Sub Worksheet_Change(ByVal Target As Range)
'PURPOSE: Checks a specific column and validates that value follow a specified pattern (numbers or letter combinations)
Dim cell As Range, rng As Range
Dim InvalidCount As Long, x As Long
x = 3 'Column to Validate
Set rng = ActiveSheet.UsedRange.Columns(x).Offset(1).Resize(ActiveSheet.UsedRange.Rows.Count - 1, 1)
For Each cell In rng.Cells
If Not UCase(cell.Value) Like "BATCH##_##Then
'Highlight Invalid Cell Yellow
msg "invalid entry please enter In following format BATCH00_00"
Next cell
End Sub
ALSO I have a another code on sheet which checks in column A there should not be any duplicate entries
Private Sub Worksheet_Change(ByVal Target As Range)
Dim rng As Range, r As Range, msg As String, x As Range
Set rng = Intersect(Columns(1), Target)
If Not rng Is Nothing Then
Application.EnableEvents = False
For Each r In rng
If Not IsEmpty(r.Value) Then
If Application.CountIf(Columns(1), r.Value) > 1 Then
msg = msg & vbLf & r.Address(0, 0) & vbTab & r.Value
If x Is Nothing Then
r.activate
Set x = r
Else
Set x = Union(x, r)
End If
End If
End If
Next
If Len(msg) Then
MsgBox "Duplicate values not allowed Invalid Entry" & msg
x.ClearContents
x.Select
End If
Set rng = Nothing
Set x = Nothing
Application.EnableEvents = True
End If
End Sub
how do I make the 1st code working & combine both to have one Private Sub Worksheet_Change
Try this (coments in code)
Private Sub Worksheet_Change(ByVal Target As Range)
Dim validationError Boolean
validationError = False
'if changed cell was not in A column, then exit sub
If Target.Column <> 1 Then Exit Sub
'check if format is valid BATCH00_00
If Not Target.Value Like "BATCH[0-9][0-9]_[0-9][0-9]" Then
MsgBox "Invalid format!"
validationError = True
Exit Sub
End If
'check for uniqueness in A column
If Application.WorksheetFunction.CountIf(Range("A:A"), Target.Value) > 1 Then
MsgBox "Values must be unique in A column!"
validationError = True
End If
If validationError Then
Application.EnableEvents = False
Target.Value = ""
Application.EnableEvents = True
End If
End Sub

VBA Macro triggering too often

My worksheet is set up with data validation dropdowns and I am wanting a macro to ONLY trigger when the value of the cell is changed from another value in the dropdown, not from the default "empty" value.
Here is what I am trying to use:
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Column = 5 Then
If IsEmpty(Target.Value) = True Then
MsgBox "Test1"
Else
MsgBox "Test2"
End If
End If
exitHandler:
Application.EnableEvents = True
Exit Sub
End Sub
My problem is that this "IsEmpty" command is reading the cell AFTER the selection not before. I want it to read what the cells value was BEFORE the selection not after.
How can I do this?
Example approach:
Const COL_CHECK As Long = 5
Private oldVal
Private Sub Worksheet_Change(ByVal Target As Range)
Dim c As Range
Set c = Target.Cells(1) '<< in case multiple cells are changed...
If c.Column = COL_CHECK Then
If oldVal <> "" Then
Debug.Print "changed from non-blank"
Else
Debug.Print "changed from blank"
End If
End If
exitHandler:
Application.EnableEvents = True
Exit Sub
End Sub
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Dim c As Range
Set c = Target.Cells(1)
oldVal = IIf(c.Column = COL_CHECK, c.Value, "")
Debug.Print "oldVal=" & oldVal
End Sub
Another approach:
This will need one cell per validation-dropdown:
Function ValChange(Cell2Follow As Range) As String
ValChange = ""
If Len(Application.Caller.Text) = 0 Then Exit Function
If Application.Caller.Text = Cell2Follow.Text Then Exit Function
MsgBox "value of the cell is changed from another value in the dropdown" & vbLf & "not from the default 'empty' value"
End Function
in a different cell, assumed the dropdown is in E6:
=E6&ValChange(E6)
application.caller.text will be the old value
(calculation must be automatic)

Private Sub Worksheet_SelectionChange/Worksheet_Change

Good day, I need to create 2 private macros in one workbook - one which stores content of cell after clicking on it and second one which will store the new value of cell and send and email with body of old text in cell and new text in cell.
Truth to be told, I'm not sure if this is the right way to do it (or if it's even possible) but I don't work with private macros often so I will appreciate any help. Thanks a lot!
That is what i got so far:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Target.Cells.Count > 1 Then Exit Sub
OldCellValue = ActiveCell.text
old_value = OldCellValue
End Sub
Private Sub Worksheet_Change(ByVal Target As Range)
Dim Area As Range
Dim OutlApp As Object
Dim IsCreated As Boolean
Dim cell As String
Dim old_value As String
Dim new_value As String
Set Area = Range("A1:E20")
If Target.Cells.Count > 1 Then Exit Sub
If Not Intersect(Target, Area) Is Nothing Then
cell = ActiveCell.Address
new_value = ActiveCell.text
On Error Resume Next
Set OutlApp = GetObject(, "Outlook.Application")
If Err Then
Set OutlApp = CreateObject("Outlook.Application")
IsCreated = True
End If
OutlApp.Visible = True
On Error GoTo 0
With OutlApp.CreateItem(0)
.Subject = "Change in table"
.to = "someones email"
.HTMLBody = "Change in cell " & "<B>" & cell & "</B><br>" _
& "Old value: " & old_value & "New value: " & new_value
On Error Resume Next
.Send
Application.Visible = True
On Error GoTo 0
End With
If IsCreated Then OutlApp.Quit
Set OutlApp = Nothing
End With
End If
End Sub
Not re-writing all your code, but in essence you have to do this to store the value when the cell is selected and then after it is changed. You don't need the newcellvalue variable as Target captures that.
Dim OldCellValue
Private Sub Worksheet_Change(ByVal Target As Range)
Dim newcellvalue
newcellvalue = Target.Value
MsgBox "Old " & OldCellValue & ", New " & newcellvalue
End Sub
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
OldCellValue = Target.Value
End Sub
I think you're on the right track. I would use a global variable to track the current/old value so you can compare it in the Worksheet_Change event.
Something like this:
Private old_value As String
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Target.Cells.Count > 1 Then Exit Sub
old_value = Target.Text
'Debug to check the old_value
'Debug.Print "old_value = " + old_value
End Sub
Private Sub Worksheet_Change(ByVal Target As Range)
Dim Area As Range
Dim OutlApp As Object
Dim IsCreated As Boolean
Dim cell As String
Dim new_value As String
Set Area = Range("A1:E20")
If Target.Cells.Count > 1 Then Exit Sub
If Not Intersect(Target, Area) Is Nothing Then
new_value = Target.Text
'Debug to compare values
'Debug.Print "new_value = " + new_value
'Debug.Print "old_value = " + old_value
If new_value <> old_value Then
'Debug to compare
'Debug.Print "new_value and old_value are different"
End If
End If
End Sub
Keep in mind that the Worksheet_SelectionChange event is going to fire every time you navigate between cells. So, if you change the value of a cell and press the Enter key, the value of old_value is going to change because you are resetting the value in the Worksheet_SelectionChange event. You need to perform the comparison and send the email before the selection changes.
Also, you'll probably want to use .Value for the cell instead of .Text. See this post for the differences: What is the difference between .text, .value, and .value2?

VBA - Change color of modified text

I have this code that changes the color of the text in a cell if it is modified. However I was looking into something that only changes the color of modified text inside the cell. For example I have in cell A1 = "This cell" and when I change it to "This cell - this is new text" I would like just to change the color of "- this is new text"
Option Explicit
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Range("A1:A100")) Is Nothing Then
If Target.Font.ColorIndex = 3 Then
Target.Font.ColorIndex = 5
Else
Target.Font.ColorIndex = 3
End If
End If
End Sub
Thanks
Here's what I put together:
Dim oldString$, newString$
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Range("A1:A100")) Is Nothing Then
newString = Target.Value
If Target.Font.ColorIndex = 3 Then
Target.Font.ColorIndex = 5
Else
Target.Font.ColorIndex = 3
End If
End If
Debug.Print "New text: " & newString
color_New_Text oldString, newString, Target
End Sub
Private Sub Worksheet_SelectionChange(ByVal Target As Excel.Range)
If Not Intersect(Target, Range("A1:A100")) Is Nothing Then
oldString$ = Target.Value
Debug.Print "Original text: " & oldString$
End If
End Sub
Sub color_New_Text(ByVal oldString As String, ByVal newString As String, ByVal theCell As Range)
Dim oldLen&, newLen&, i&, k&
oldLen = Len(oldString)
newLen = Len(newString)
Debug.Print newString & ", " & oldString
For i = 1 To newLen
If Mid(newString, i, 1) <> Mid(oldString, i, 1) Then
Debug.Print "different"
Debug.Print theCell.Characters(i, 1).Text
If theCell.Characters(i, 1).Font.ColorIndex = 3 Then
theCell.Characters(i, 1).Font.ColorIndex = 5
Else
theCell.Characters(i, 1).Font.ColorIndex = 3
End If
End If
Next i
End Sub
It's two global variables, a Worksheet_SelectionChangeand Worksheet_Changeto get the strings.
It is laborious:
detect that a cell has changed in the range of interest
use UnDo to get the original contents
use ReDo to get the new contents
compare them to get the changed characters
use the Characters property of the cell to format the new characters
I would use UnDo to avoid keeping a static copy of each of the 100 cells.
using the tip from Gary's Student, I retain the old value of cell and compare with the new value. Then use the lenght to get the 'difference' and color the 'characters'. Here's the modification:
Option Explicit
Public oldValue As Variant
Public Sub Worksheet_SelectionChange(ByVal Target As Range)
oldValue = Target.Value
End Sub
Private Sub Worksheet_Change(ByVal Target As Range)
Dim oldColor
If Not Intersect(Target, Range("A1:A100")) Is Nothing Then
If Target.Value <> oldValue Then
oldColor = Target.Font.ColorIndex
Target.Characters(Len(oldValue) + 1, Len(Target) - Len(oldValue)).Font.ColorIndex = IIf(oldColor = 3, 5, 3)
End If
End If
End Sub
P.S. Sorry my english
This will change the font, but it's not perfect. Seems if you have different font colours in the same cell then Target.Font.ColorIndex returns NULL so it only works on the first change.
Option Explicit
Dim sOldValue As String
Private Sub Worksheet_Change(ByVal Target As Range)
Dim sNewValue As String
Dim sDifference As String
Dim lStart As Long
Dim lLength As Long
Dim lColorIndex As Long
On Error GoTo ERROR_HANDLER
If Not Intersect(Target, Range("A1:A100")) Is Nothing Then
sNewValue = Target.Value
sDifference = Replace(sNewValue, sOldValue, "")
lStart = InStr(sNewValue, sDifference)
lLength = Len(sDifference)
If Target.Font.ColorIndex = 3 Then
lColorIndex = 5
Else
lColorIndex = 3
End If
Target.Characters(Start:=lStart, Length:=lLength).Font.ColorIndex = lColorIndex
End If
On Error GoTo 0
Exit Sub
ERROR_HANDLER:
Select Case Err.Number
'I haven't added error handling - trap any errors here.
Case Else
MsgBox "Error " & Err.Number & vbCr & _
" (" & Err.Description & ") in procedure Sheet1.Worksheet_Change."
End Select
End Sub
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Not Intersect(Target, Range("A1:A100")) Is Nothing Then
sOldValue = Target.Value
End If
End Sub
Edit: It will only work with a continuous string. Maybe can change to look at each character in sOldValue and sNewValue and change colour as required.
Try with below
Private Sub Worksheet_Change(ByVal Target As Range)
Dim newvalue As String
Dim olvalue As String
Dim content
Application.EnableEvents = False
If Not Intersect(Target, Range("A1:A100")) Is Nothing Then
If Target.Font.ColorIndex <> -4105 Or IsNull(Target.Font.ColorIndex) = True Then
newvalue = Target.Value
Application.Undo
oldvalue = Target.Value
Content = InStr(newvalue, Replace(newvalue, oldvalue, ""))
Target.Value = newvalue
With Target.Characters(Start:=Content, Length:=Len(newvalue)).Font
.Color = 5
End With
Else
Target.Font.ColorIndex = 3
End If
End If
Application.EnableEvents = True
End Sub

Excel VBA, How to Loop a Msgbox when text in cell changes to "News" to answer of Msgbox in next column

I'm trying to create a MsgBox that automatically pops up with a prompt of "Yes or No" when a cell in a column changes from blank to "News", and to put the answer into the next column.
I will be continuing to add to rows over time so it has to automatically pop up when the cell changes from blank to "news" and input the answer into the newly added cell to the right.
I'm pretty sure I need the For each loop, but honestly I'm a little lost and get a mismatch error during debug at the If Intersect line.
Private Sub Worksheet_Change(ByVal Target As Range)
Dim myRange As Range
Set myRange = Range("G2:G1000")
If Intersect(myRange, Target) Then
If Range("G2").Value = "News" Then Answer = MsgBox("Good?", vbYesNo)
Answer = ActiveCell.Offset(0, 1) = 1 'not sure if this is right, or is it Range.Offset?
Dim cel As Range
For Each cel In Range("G2:G1000")
If cel.Value = "News" Then Answer = MsgBox("Good?", vbYesNo)
Answer = ActiveCell.Offset(0, 1) = 1 'not sure if this is right, or is it Range.Offset?
Exit For
Next
End If
End Sub
Here you go:
Private Sub Worksheet_Change(ByVal Target As Range)
On Error Resume Next
If Target.Column = 7 Then
If Target.Count = 1 Then
If LCase$(Target) = "news" Then
Application.EnableEvents = False
Target(, 2) = Array("Yes", "No")(MsgBox("Good?", vbYesNo) - 6)
End If
End If
End If
Application.EnableEvents = True
End Sub
