VBA - Open a msgbox when cell value = 1 - vba

I need help with a very basic vba macro. When the value in A6 is equal 1 a msgbox needs to appear in the workstation. I developed the below code but the problem is that when I add any other information in the spreadsheet (for example, if I write "i love pizza" in B6) the msgbox will prompt again and I need it to prompt just one time, just when I set the value of A6 = 1. Could you please help me?
Private Sub Worksheet_Change(ByVal Target As Range)
If Range("A6").Value = 1 Then
MsgBox "THIS IS A MSGBOX."
End If
End Sub
#edit
I forgot one very important thing... the value "1" is getted with a VLOOKUP so its not insert manually by the user, i'm sorry about this. I tried the codes you people answered and it worked just when I put the vlue manually and as I said in the edit start, the value is set with a VLOOKUP. Any other tips, please?

You need to check if the change is due to the cell A6 being changed, rather than a different cell.
Try this:
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Column = 1 And Target.Row = 6 Then
If Target.Value = 1 Then
MsgBox "THIS IS A MSGBOX."
End If
End If
End Sub

You can use this code instead of the previous one
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = Me.Range("A6").Address And Me.Range("A6").Value = 1 Then
MsgBox "THIS IS A MSGBOX."
End If
End Sub
Target is the changed cell in Excel. so for every change event, I check if the target is Range("A6").

Pertaining to the statment : and I need it to prompt just one time, you need to save the oldvalue. So the prompt is displayed only once, when you set the value to 1. If A6 is already 1 and then you type 1 again, no prompt.
Option Explicit
Dim oldVal
Private Sub Worksheet_Change(ByVal Target As Range)
If (Target.Address = "$A$6") Then
If Target.Value = 1 And Target.Value <> oldVal Then
oldVal = Target.Value
MsgBox "Test"
End If
End If
End Sub

You need to check inside the Worksheet_Change event, that only if Cell "A6" is pressed, then continue. And afterwards, check if the value of the cell equals 1.
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Range("A6")) Is Nothing Then
If Target.Value = 1 Then MsgBox "THIS IS A MSGBOX."
End If
End Sub

Try this:
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = "$A$6" Then
If Target.Value = 1 Then
MsgBox "THIS IS A MSGBOX."
End If
End If
End Sub

Select specific cell after Inputting values In previous cells

so I have an input sheet and want to move the activated cell to another cell after data has been typed in/chosen.
So far I've got this:
Private Sub Worksheet_Change(ByVal Target As Excel.Range)
If Range("F11").Value <> "" Then
Range("F13").Select
End If
End Sub
But the problem is this does not seem to work with more cells and ranges for some reason. So for example if then F13 is selected I want to move to F16. If F16 is selected I want to move to F17. So no rule here like always 2 rows down. How can I solve this?

This is a simply type of a boilerplate, which can be increased further, following a specific business logic.
If you want to Add Range("D5") with 3 rows, then add it to the Union in this line: If Intersect(Target, Union(Range("F16"), Range("F13"))) and then make a Case Range("D5").
Private Sub Worksheet_Change(ByVal Target As Excel.Range)
If Target.Cells.Count > 1 Then Exit Sub
If Target.Row > Rows.Count - 2 Then Exit Sub
If Target = vbNullString Then Exit Sub
If Intersect(Target, Union(Range("F16"), Range("F13"))) Is Nothing Then Exit Sub
Select Case Target
Case Range("F16")
Target.Offset(1).Select
Case Range("F13")
Target.Offset(2).Select
End Select
End Sub

Excel Macro to update Cells automatically based on User selection

I am trying to write a Macro that updates 4 Cell if the User select "Mailing" From Cell A1. If the User selects "Mailing" in A1, then Automatically update A2,A3,A4, and A5 to Value in B1. If the User selects something other than "Mailing", Then all four cells should be blank and the user should be able to type in any value. Any help is appreciated. Thanks
I have gotten this far, but VBA is not my thing:
Sub test()
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = "$A$1" And Target.Value = "Mailing" Then
Range("A2:A4").Value = "B1"
End If
End Sub
As the others have mentioned, you just need to put it to Sub Worksheet_Change. Note that if you are "typing" the word into cell A1, you will actually be in A2 after the "Enter".
Private Sub Worksheet_Change(ByVal Target As Range)
If Range("A1").Value = "Mailing" Then
Range("A2:A4").Value = "B1"
End If
End Sub
The problem is you are trying to change the value of some of the cells in your code, so the code should run itself. You need to turn off events before changing the cell values and then turn it back on:
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = "$A$1" And Target.Value = "Mailing" Then
Application.EnableEvents = False
Range("A2:A4").Value = "B1"
Application.EnableEvents = True
End If
End Sub

VBA - Open a UserForm by clicking anywhere in a specific column

I would like to build a makro in VBA which opens a UserForm when I click in a cell in a specific column, for more details look here.
With this code (from Mr.Burns):
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Selection.Count = 1 Then
If Not Intersect(Target, Range("A1")) Is Nothing Then
'name of userform .Show
End If
End If
End Sub
I was able to open the UserForm by clicking in the cell A1, but not by clicking in any cell inside the column A.
I tried to solve this problem with this code:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Selection.Count = 1 Then
Dim check As Boolean
check = True
If check Then
Dim i As Long
For i = 1 To 100000
If Not Intersect(Target, Range("A" & i)) Is Nothing Then
UserForm1.Show
check = False
End If
Next
End If
End If
End Sub
It actually works fine, but it is very slow, is there any better possibility to solve this?
To display the form when a cell is selected in column A:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
' if target is one cell and in column A
If Target.Columns.count = 1 And Target.Rows.count = 1 And Target.Column = 1 Then
UserForm1.Show
End If
End Sub
You can use .count and .column property together with AND and it will become so much simple and fast. Following code triggers pop-up if u click in column A on active-sheet
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
On Error GoTo errorhandler
If Target.Count = 1 And Target.Column = 1 Then '.count to check if only one cell is selected and .column to check if it is a first column
'UserForm1.Show
'Do whatever you want to do here like opening User form
MsgBox "You clicked in column A"
End If
errorhandler:
End Sub

Retrieve the cell you used a macro in

I want to find the exact cell where my macro is if I press it
For example, all of these pictures are the same macro. Somehow I need to find the cell where I pressed on.
I find this quite hard to explain so not sure if you will understand what I mean but it would be great if someone could help me.
Thank you in advance
Look at the Worksheet_SelectionChange event.
The Target is a range that you can access the properties of and work with.
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
'You can access the row and column of the target itself
With ActiveWindow
.ScrollRow = Target.Row
.ScrollColumn = Target.Column
End With
End Sub
If you have a value in the cells with the pictures you can access that.
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Dim str as String
str = Target.Value
msgbox (str)
End Sub

excel vba on cell change error

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Range = Range("A1") Then
If Range("A1").Value <> Range("A2").Value Then
Range("C1").Value = Range("C1").Value + 1
Range("A2").Value = Range("A1").Value
End If
End If
End Sub
that's the code however when i copy paste a set off cell, let's say 2 columns and 3 rows
it produce runtime error 13 type mismatch on line
If Target.Range = Range("A1") Then
why?
i simply wants the vba to do something everytime cell A1 changes
the value of A1 itself is an excel sum formula
You get type-missmatch error, becase you're trying to compare range (containing many cells) with single cell. If you want to do something every time cell A1 changed, use this one instead:
Private Sub Worksheet_Change(ByVal Target As Range)
Application.EnableEvents = False
On Error GoTo ErrHandler
If Not Intersect(Target, Range("A1")) Is Nothing Then
If Range("A1").Value <> Range("A2").Value Then
Range("C1").Value = Range("C1").Value + 1
Range("A2").Value = Range("A1").Value
End If
End If
ExitHere:
Application.EnableEvents = True
Exit Sub
ErrHandler:
Resume ExitHere
End Sub
also note that I'm using Application.EnableEvents = False - it's a good habbit for Worksheet_Change event to use it. It prevents code from infinity firing itself each time you change any cell in event handler code.
UPD:
Btw, the value of A1 itself is an excel sum formula - you can't track changes of formula using above approach. I covered in details how you can do it in this question: Using Worksheet_Calculate event for tracking changes of formula
Simoco's answer should work for you. Another way (the one I usually use, though only out of habit) is to compare the addresses:
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = Range("A1").Address Then
If Range("A1").Value <> Range("A2").Value Then
Range("C1").Value = Range("C1").Value + 1
Range("A2").Value = Range("A1").Value
End If
End If
End Sub
You are getting an error because Target.Range is not defined. You should either just refer to Target (a Range Object) or Target.Address (the address of the Range Object). Secondly, depending on the context, Range("A1") refers to either the cell A1 itself (a Range Object) or the value in cell A1 (a literal value). You need to carefully think what you want to compare to what.
If, as you said, you want the comparison done whenever the value in Range("A1") changes then you should follow Simoco's suggestion.
