New to writing code in VBA, and I need to add in a way to count/track how often a macro is used. I'm struggling to find any examples of a code that would perform this function. Requesting any examples there might be for this.
Excel VBA doesn't have any built-in storage that persists across sessions - when the application is closed, all variables are released. However you do have a readily available source of storage - the workbook itself. Here's one way to do it:
Make a worksheet called Counter (or something). Optionally, hide it so no one messes with it. Then, when your macro runs, increment the value of Cell(1,1), which will hold your counter value.
Dim runCount As Integer
Dim counterWS As Worksheet
Set counterWS = ThisWorkbook.Worksheets("Counter")
If counterWS.Cells(1,1) <> vbNullString And IsNumeric(counterWS.Cells(1,1)) Then
runCount = counterWS.Cells(1,1) + 1
Else
runCount = 1
End If
counterWS.Cells(1,1) = runCount
Use static when declaring your variable.
From "EXCEL" Ytics:
Can we declare a variable to retain its value from a previous run?
Static Declaration within a procedure limits the variable to that procedure – but helps retain values of variables from previous runs, until forcefully reinitialized by explicit declaration using ‘ReDim’ or value setting.
Sub MySub( )
Static Cnt As Integer
Dim Msg As String
Cnt = Cnt + 1
Msg = “You’ve run the procedure ” & Cnt & ” times”
MsgBox Msg
End Sub
This will build a table for you on a hidden sheet showing all historical uses of the macro up to the nth time the macro was used along with a time stamp so you know when the macro was used. With this, you can use equations to extract exact data that you want as well. If you want a cell to show usage count, just to "Countif("A:A","*")-1” ... (minus 1 to ignore the header in A1)
To Implement this macro:
Create a new sheet titled "MacroCount"
Set A1 = "Instance"
Set B1 = "Time Stamp"
I would personally make this the last thing the macro does so it will only count the instance once the macro completes all of its assigned duties.
Also, Remove the "Sub MacroCount()" & "End Sub" from the below code.
Sub MacroCount()
Dim WS As Worksheet
Set WS = ThisWorkbook.Sheets("MacroCount")
Application.Screenupdating = False
WS.Visible = True
Dim LRow As Long
LRow = WS.Range("A" & Rows.Count).End(xlUp).Offset(1).Row
WS.Range("A" & LRow).Value = LRow - 1
WS.Range("B" & LRow).Value = Now()
WS.Visible = False
Application.Screenupdating = True
End Sub

Beginner here and I managed to modify a code to extract data from a sheet and copy and paste them to other sheets. Problem is when I click run Macro or the button assigned to the Macro, it is duplicating rows again. Please help me to avoid the duplication.
TIA

When you find that your code isn't doing what you expect, try stepping through it line-by-line and see exactly where and when it goes wrong. You can do this by pressing F8 while your cursor is anywhere in your macro. I also recommend commenting out Application.ScreenUpdating = False until your code is working as expected. Otherwise, following the code's behavior can become difficult when the code is supposed to write things to worksheets.
You've found that your code is duplicating entries. Let's check all places in your macro that write data to the sheet. There is only one place: inside your For i = 2 to LastRow loop. Because you have set up a loop, you are expecting (or at least preparing) for this block of code to run more than once. The next question should be, why is the data not changing between two iterations like you're expecting?
Check that Else block of code. It seems like you copy the headers, add a new sheet, and then use the ActiveSheet to specify which sheet to write the data. Is ActiveSheet the sheet you think it is? (Very easy to verify with line-by-line debugging.) If you really want to use ActiveSheet, make sure the sheet you expect to be active is active with Worksheets(Worksheets.Count).Activate. This will activate the last worksheet, which is where you want to write your data.
Try stepping line-by-line through your code and see if this is correct before modifying your code.
With below code, no errors are displayed, the read file opens but it seems not data is copied.
I am trying to copy only a number of columns, but it seems nothing is been copied to current workbook.
Any help would be appreciated as I am very new with VBA
Sub ReadDataFromCloseFile()
On Error GoTo ErrHandler
'stop screen update
Application.ScreenUpdating = False
Dim src As Workbook
Dim sTheSourceFile As String
sTheSourceFile = "C:\Users\grmn\Desktop\testreadfile.xlsx"
Set src = Workbooks.Open(sTheSourceFile, True, True)
Dim iRowsCount As Long
'source of data
With src.Worksheets("Sheet1")
iRowsCount = .Range("A1:A" & .Cells(Rows.Count, "A").End(xlUp).Row).Rows.Count
End With
Dim iCnt As Long
'destination sheet thisWorkbook.sheet("rapport")
For iCnt = 1 To iRowsCount
Worksheets("rapport").Range("A" & iCnt).Formula = src.Worksheets("Sheet1").Range("A" & iCnt).Formula
Worksheets("rapport").Range("F" & iCnt).Formula = src.Worksheets("Sheet1").Range("B" & iCnt).Formula
Next iCnt
'close but not overide source file (src).
src.Close False
Set src = Nothing
ErrHandler:
Application.EnableEvents = True
Application.ScreenUpdating = True
End Sub
No worries being new, we all were at some point.
The first part of your code 'source of data doesn't work as intended. iRowsCount is an Integer and not an Array. To make use of an array, as you seemingly tried to do, you should use
Dim iRowsCount(8) As Long
With src.Worksheets("Sheet")
iRowsCount(1) = .Range("A1:A" & .Cells(Rows.Count, "A").End(xlUp).Row).Rows.Count
' ...
End With
' ...
If you use an Integer only the last row will be assigned. So if "AT", for some reason, has 5 rows, iRowsCount will be 5. Nothing else. Not accounting for "AQ" or "AS".
But in your case, Integer/Long would probably suffice if all rows have the exact same count. One assignment would be enough then.
Regarding .Formula - are you really trying to write formulas? Have you tried .value instead?
And, what may be the crux of the matter, try Worksheets("rapport").Save or Worksheets("rapport").SaveAs at the end of your function.
(Haven't tested it on my end so far.)
Additionally, please remember to set Exit Sub (or Exit Function respectively, if a Function) to avoid executing ErrHandler if no error occurs.
(Sorry, I'm new to Stackoverflow, so I can't write comments as of yet.)
(Edit: Thanks for the reminder, #FunThomas, Integer is only -32768 to 32767. Long is 8 bytes.)
How can I concatenate the word "Sheet" with a number (say, 2) to form a string that can be used as the code name of a sheet.
I've tried the following piece of code but it doesn't seem to work.
Sh = "Sheet" & 2
Range("A1") = Sh.index
If you want to refer the sheet just based on index you could try something like this as well ... hope it works for you
Sub trial()
i = 2
Sheets(i).Select
End Sub
I assume you want to check if a given ►string argument (CodeNameString) refers to a valid Code(Name) in the VBA project. *)
If so, the following function returns the worksheet to be set to memory; otherwise the second argument IsAvailable passed by reference will change to False and can be used for error checks (c.f. ExampleCall below).
Function SheetByCodename(ByVal CodeNameString As String, ByRef IsAvailable As Boolean) As Object
'check for same CodeName in Sheets collection
Dim ws As Object
For Each ws In ThisWorkbook.Sheets
If ws.CodeName = CodeNameString Then ' check for string identity
Set SheetByCodename = ws ' set sheet object to memory
IsAvailable = True ' assign true to 2nd argument passed ByRef
Exit For
End If
Next
End Function
Example call
Sub ExampleCall()
dim cnt As Long: cnt = 2 ' << change example counter
Dim okay As Boolean ' << needed variable passed as 2nd function argument
With SheetByCodename("Sheet" & cnt, okay)
If okay Then
Debug.Print _
"a) Worksheet Name: " & .Name & vbNewLine & _
"b) Sheet's Code(Name) in Project: " & .CodeName
Else
Debug.Print "Given string refers to no valid Code(Name)."
'do other stuff to handle the wrong input
End If
End With
End Sub
*) Take note of #RonRosenfeld 's important remarks in comment:
"Codename is assigned when the worksheet is created. It can be changed in the properties window. In order to change it programmatically, you need to enable Trust Access to the VBA object model. Otherwise, it's a read-only property. "
I am trying to get better coding practice and using generic function.
I am working with several workbooks from a master file.
For example if I want to get the last row I am using the following line of code.
LastRow=Range("A" & Rows.Count).End(xlUp).Row
To retrieve the value with a function I build the function:
-Function 1
Function GetLastRow() As Integer
GetLastRow = Range("A" & Rows.Count).End(xlUp).Row
End Function
Now from my Sub Main() I want to use GetLastRow() for different workbooks or worksheets. I think it is not a good thing to Activate the workbook before calling my function.
Then should I transmit each time the workbook name and worksheet number to my function and change my function to:
-Function 2
Function GetLastRowIn(sWb As String, iWs As Integer) As Integer
GetLastRowIn = Workbooks(sWb).Worksheets(iWs).Range("A" & Rows.Count).End(xlUp).Row
End Function
Or is there a better/simpler way to transmit the workbook and worksheet in which I want to apply the function while keeping it with no argument as in Function 1?
Thanks for your answers!
To make a function more generic you can allow for some flexibility,
but also impose some rulles for the function calls
Generic Function
Option Explicit
Public Function GetLastRow(ByRef ws As Worksheet, Optional ByVal fromCol As Long = 1) As Long
Dim invalidWS As Boolean, lastRow As Long
If Not ws Is Nothing Then 'check 1st param
On Error Resume Next 'check that ws reference is valid (delted WS invalidates ws)
invalidWS = Len(ws.Name) > 0
invalidWS = Err.Number <> 0 'No error if Err.Number = 0
On Error GoTo 0
If Not invalidWS Then
If fromCol > 0 And fromCol <= ws.Columns.Count Then 'validate 2nd param
lastRow = ws.Cells(ws.Rows.Count, fromCol).End(xlUp).Row
'check if WS.fromCol is empty
If lastRow = 1 And Len(ws.Cells(1, fromCol)) = 0 Then lastRow = 0
End If
End If
End If
GetLastRow = lastRow
End Function
Test Sub
Public Sub TestGetLastRow()
'show results in the Immediate Window (VBA Editor: Ctrl+G)
Debug.Print GetLastRow(Sheet1, 1) 'CodeName of WS
Debug.Print GetLastRow(Workbooks(1).Worksheets(1)) 'WS Index
Debug.Print GetLastRow(ActiveWorkbook.Worksheets("Sheet3"), 3) 'WS name (string)
Debug.Print GetLastRow(ThisWorkbook.Worksheets(1), 0) 'invalid column (or -3)
Dim ws As Worksheet
Set ws = Sheet3
Application.DisplayAlerts = False
ws.Delete 'invalidate ws variable
Application.DisplayAlerts = True
Debug.Print GetLastRow(ws, 1) 'function call with invalid ws object
End Sub
Always use Option Explicit to allow the compiler to catch spelling mistakes in variable names
Validate all input
The function call may not include a valid Worksheet, or column number
Allow the Worksheet to be specified by CodeName, WS Index, or WS Name (string)
Allow a default column ID by using Optional for the 2nd parameter
Impose the call to send only a Worksheet object as the first parameter
If you accept strings for it you need to first check that Worksheet("Invalid") exists
Impose the call to request column by Index
If you allow strings in column ID you need to check that the string is between "A" and "XFD"
String length between 1 and 3, and also not allow strings like "XYZ"
This would require a separate function that checks each letter in the string
Strings also create potential for more maintenance if MS decides to increase max columns
Make the function for one purpose (like you did) - don't include other functionality later on
The function should be self contained
Able to detect and handle all possible errors and unexpected input
And generate the most generic and usable output
By returning a 0 in this particular function, calls that expect a valid number will error out for row 0
So you may want to change it to return 1 even if the sheet is empty
and check the top cell if blank after the call returns
As a note:
several workbooks from a master file
A Workbook is a file
A Worksheet is a tab inside a file (a file can contain multiple sheets / tabs)
Always be explicit with all object
Range("A" & Rows.Count).End(xlUp).Row implicitly uses ActiveWorkbook.ActiveSheet
Translates to ActiveWorkbook.ActiveSheet.Range("A" & Rows.Count).End(xlUp).Row
If you need to work with several Workbooks and Worksheets, fully qualify your calls
`Workbooks("Book1").Worksheets("Sheet3").Range("A" & Rows.Count).End(xlUp).Row
`Workbooks("Book2").Worksheets("Sheet2").Range("A" & Rows.Count).End(xlUp).Row
so Excel can access the exact object you need to work with
If you use full references your code doesn't depend on active objects
- If a user activates a different Workbook, or Worksheet the code will continue to work without errors
Hope this helps
PS. When using row variables always declare them as Long to be able to handle more than the Integer maximum of 32,767 - currently Excel has a max of 1,048,576 rows (in the future this max can increase even higher)
It is very simple but yet I can't figure it out. Maybe because it cannot be done? Regardless here we go:
I would like to use a combobox that will, when selected, input cells with text values, functions and reference to external cells.
First line of the options would be to have the name populated.
Second line is a formula that would change from course to course.
Third line would provide a cell with a reference to another cell's content from another file. So if multiple course file are used I can have one master file that if I change the content of a cell the change will reflect on all the course file cells that are referring to it once updated.
This is in crude code form what I would like it to perform.
Private Sub ComboBox1_Change()
If Me.ComboBox1.Value = "ITCourse" Then
Worksheets("PARADE STATE").Range("I1").Value = "ITCourse"
Worksheets("Data Base").Range("C1").Value = IF(V9>70,"Prep Week",IF(V9>65,"Week 1",IF(V9>60,"Week 2",IF(V9>55,"Week 3",IF(V9>50,"Week 4",IF(V9>45,"Week 5",IF(V9>40,"Week 6",IF(V9>35,"Week 7",IF(V9>30,"Week 8",IF(V9>25,"Week 9",IF(V9>20,"Week 10",IF(V9>15,"Week 11",IF(V9>10,"Week 12",IF(V9>5,"Week 13",IF(V9>0,"Week 14")))))))))))))))
Worksheets("Week 1").Range("B2").Value = 'N:\ITcourse\00 - Data Base\[ITcourse.xlsx]Sheet'!$A$3
End If
If Me.ComboBox1.Value = "HRCourse" Then
Worksheets("PARADE STATE").Range("I1").Value = "HRCourse"
Worksheets("Data Base").Range("C1").Value = IF(V9>40,"Prep Week",IF(V9>35,"Week 1",IF(V9>30,"Week 2",IF(V9>25,"Week 3",IF(V9>20,"Week 4",IF(V9>15,"Week 5",IF(V9>10,"Week 6",IF(V9>5,"Week 7",IF(V9>5,"Week 8")))))))))
Worksheets("Week 1").Range("B2").Value = 'N:\ITcourse\00 - Data Base\[HRcourse.xlsx]Sheet'!$A$3
End If
End Sub
Thank you!
You need a function that returns the number of weeks for any given course name. This function should use a Dictionary to store the information, and the dictionary may be loaded from a dedicated worksheet.
Function WeeksPerCourse(courseName As String) As Long
Static dict As Scripting.Dictionary
If dict Is Nothing Then
' Fill the dictionary here. Note that it is better
' to load the values from a dedicated, hidden worksheet
Set dict = CreateObject("Scripting.Dictionary")
dict("ITCourse") = 14
dict("HRCourse") = 8
' Etc...
End If
WeeksPerCourse = dict(courseName)
End Function
With this function available, your procedure can be simplified like follows:
Private Sub ComboBox1_Change()
Dim course As Sting: course = Trim(ComboBox1.value)
Worksheets("PARADE STATE").Range("I1").value = course
'Dim nWeek As Long
'nWeek = WeeksPerCourse(course) - Worksheets("PARADE STATE").Range("V9").value / 5
'Worksheets("Data Base").Range("C1").value = IIf(nWeek < 1, "Prep Week", "Week " & nWeek)
Worksheets("Data Base").Range("C1").Formula = "= ""Week "" & INT((WeeksPerCourse('PARADE STATE'!I1) - 'PARADE STATE'!V9)/5)"
Worksheets("Week 1").Range("B2").Formula= "='N:\ITcourse\00 - Data Base\[" & course & ".xlsx]Sheet'!$A$3"
End Sub
