update cell and paste it to another cell vba - vba

Question

I am quite new in excel vba and I would really appreciate if you can assist me.
The thing is that I have cell which updates each minute because it is linked with a function to Blomberg. The thing is that I want that each time cell updates excel copies it and pastes to another, new cell that i can observe the intra day changes.
I have come up with some codes but I can copy and paste only to one, similar cell.It looks like following:
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Cells.Count > 1 Then Exit Sub
If Not Intersect(Target, Range("E4")) Is Nothing Then
Range("E4").Copy
Range("E4").PasteSpecial xlPasteValues
End If
End Sub
Any help would be highly appreciated.

If I understand your problem correctly you want to copy the value to a new cell, for logging purposes? What I would do in this case is have another sheet for logging the values named "logger_sheet" I paste a value in cell a1 when the blomberg cell updates, copy the value into my logger_sheet cell a2 when it changes copy it to a3 then a4 etc.
Here is your updated code. It assumes you have a sheet named "logger_sheet" (if you dont have one, create it) to store all the previous values. When the blomberg cell updates, it copies the value and pastes it to the next avaliable logging_sheet cell. I have developed a function that finds the last used row in a specified sheet and column. Try it out
Also there is a line you can uncomment if you want to prevent excel from flashing, I labeled it in the code
Sub Worksheet_Change(ByVal Target As Range)
If Target.Cells.Count > 1 Then Exit Sub
target_cell = "E4"
col_to_log_data = "A"
logging_Sheet = "logger_sheet"
If Not Intersect(Target, Range("E4")) Is Nothing Then
'uncomment this line to stop the "flashing"
'Application.ScreenUpdating = False
'gets the name of the current sheet
data_sheet = Range(target_cell).Parent.Name
Range(target_cell).Select
Selection.Copy
'gets the next free row from column a of the logging sheet (the next free row is
'the last used row + 1)
next_free_row = GetLastRowByColumn(CStr(col_to_log_data), CStr(logging_Sheet)) + 1
'pastes the value
Sheets(logging_Sheet).Range(col_to_log_data & CStr(next_free_row)).PasteSpecial Paste:=xlPasteValues
Application.CutCopyMode = False
'switches back to the data sheet
Sheets(data_sheet).Select
'make sure you turn screen updating on (if it was never off it still works)
Application.ScreenUpdating = True
End If
End Sub
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
'this finds the last row in a specific column
'PARAMS: col_to_check, the clumn we want the last row of
' Opt: sheet_name, the sheet you want to check last row of
' default is current sheet if not specified
'RETURN: the last row number used in the sheet
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
Function GetLastRowByColumn(col_to_check As String, Optional sheet_name As String)
'gets current sheet name
the_current_sheet = ActiveSheet.Name
'if the user didnt' specify a sheet use the current one
If (Len(sheet_name) = 0) Then
sheet_name = the_current_sheet
End If
'gets last row
GetLastRowByColumn = Sheets(sheet_name).Range(col_to_check & "65536").End(xlUp).Row
'returns to original sheet
Sheets(the_current_sheet).Select
End Function

How about this? It will transfer E4 to Sheet2 in a new row each time E4 changes.
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Cells.Count > 1 Then Exit Sub
If Target.Address = "$E$4" Then Sheets("Sheet2").Cells(Rows.Count, "F").End(xlUp).Offset(1) = Target
End Sub

I'm making the assumption you want to log every change of values.
I would advise to keep a log in a separate sheet. Let's call it LogSheet.
Sub WriteLog(ByRef r As range)
Dim Lastrow as integer
With ThisWorkBook.WorkSheets("LogSheet")
LastRow = .Cells(.Rows.Count,"A").End(XlUp).Row
.Range("A" & LastRow + 1).Value = Now & " - " & r.Value
End With
End Sub
This sub will basically write all changes in column A of our log sheet with a timestamp!
Now, we need to make changes to your code in order to tell, to make logs whenever there is a change. To do so, we're going to make a call to our function and tell to copy the content of the range("E4") (The one that gets updated all the time)
If Not Intersect(Target, Range("E4")) Is Nothing Then
'add this line
WriteLog(ActiveSheet.Range("E4"))
Try it now.
