How do I make value static in last row value? - vba

Question

Here is the code below:
Public n as Long ' <--above sub procedure
With Sheets("Sheet1").Range("A6").Offset(n, 0)
If n = 0 Then
.Value = 1
Else
.Value = .Parent.Range(.Address).Offset(-1, 0) + 1
End If
n = n + 1
End With
(See pic below) If I delete 4 then click command button again it just reset back to 1. I want to make it static so even I deleted the last value of row it still continue increment from the last value.
Store number
1
2
3
4

Answer 1

Try this:
Sub Test()
Dim trow As Long
With Sheets("Sheet1") '~~> change to suit
trow = .Range("A:A").Find(vbNullString, [A5]).Row
With .Range("A" & trow)
If trow = 6 Then .Value = 1 _
Else .Value = .Offset(-1, 0).Value + 1
End With
End With
End Sub
Above code finds the first blank cells. If it is A6 it assigns a value of 1.
Otherwise it assigns previous cell value plus 1. Is this what you're trying?
Edit1: Explanation
trow = .Range("A:A").Find(vbNullString, [A5]).Row
This finds the first empty row in Column A starting A5.
[A5] is used to return Range("A5") object. So it can also be written as:
trow = .Range("A:A").Find(vbNullString, .Range("A5")).Row
We used a VBA vbNullString constant as What argument in Range Object Find Method.
Find Method returns a Range Object so above can be written also like this:
Sub Test()
Dim r As Range
With Sheets("Sheet1") '~~> change to suit
Set r = .Range("A:A").Find(vbNullString, [A5])
With r
If .Row = 6 Then .Value = 1 _
Else .Value = .Offset(-1, 0).Value + 1
End With
End With
End Sub

What your asking for, a button with memory doesn't sound neatly solvable using just VBA.
You could potentially have a list on a hidden sheet that gets a value added to it each time the commandButton is pressed and it writes the max of the list values back to the target cell?
Alternatively you could investigate using a scrollbar from the form control section of the developer tab with a link to your target cell. I often use this technique for interactive sheets.
Named Range Method
Public sub btnPress
dim val as long
val = Range("PreviousCellValue")
set Range("PreviousCellValue") = val+1
Sheets("Sheet1").Range("A6").Offset(n, 0).value = Range("PreviousCellValue")
End sub btnPress
