I have a few cells in my excel workbook which are available for a client to put his own values. I wanted the workbook to initialize those cells with default values. In order to do so I have a worksheet "Arkusz do makr", where I store the values.
In a module "GM" I declare a variable to reference my worksheet easier like this:
Public M As Worksheet
Then I initialize this variable and set my default values like this (in ThisWorkbook):
Private Sub Workbook_Open()
Set M = Worksheets("Arkusz do makr")
Worksheets("Values").Range("Value1") = M.Range("Value1")
Worksheets("Values").Range("Value2") = M.Range("Value2")
Worksheets("Values").Range("Value3") = M.Range("Value3") `etc
End Sub
Now sometimes this works like a charm, and sometimes, when I open the workbook I get a
Run-time error '91': Object variable or With block variable not set.
Could someone please explain this behaviour to me? Additionally I would like to ask if my approach makes sense, since I have a hard time grasping the order of events in excel as well as the range of its objects.
EDIT: Additionally I should mention that the Debug function highlights the first Worksheets... line in my code. In specific worksheets I reference the M object as well, though I thought it changes anything here...
Try to change the code of this Sub like below.
I have added a simple error handling - if there is no worksheet "Arkusze do makr" or "Values" in your workbook, warning message is displayed and default values are not copied.
You can find more comments in code.
Private Sub Workbook_Open()
Dim macrosSheet As Excel.Worksheet
Dim valuesSheet As Excel.Worksheet
'------------------------------------------------------------------
With ThisWorkbook
'This command is added to prevent VBA from throwing
'error if worksheet is not found. In such case variable
'will have Nothing as its value. Later on, we check
'the values assigned to those variables and only if both
'of them are different than Nothing the code will continue.
On Error Resume Next
Set macrosSheet = .Worksheets("Arkusz do makr")
Set valuesSheet = .Worksheets("Values")
On Error GoTo 0 'Restore default error behaviour.
End With
'Check if sheets [Values] and [Arkusz do makr] have been found.
'If any of them has not been found, a proper error message is shown.
'In such case default values are not set.
If valuesSheet Is Nothing Then
Call VBA.MsgBox("Sheet [Values] not found")
ElseIf macrosSheet Is Nothing Then
Call VBA.MsgBox("Sheet [Arkusz do makr] not found")
Else
'If both sheets are found, default values are copied
'from [Arkusz do makr] to [Values].
'Note that if there is no Range named "Value1" (or "Value2" etc.)
'in any of this worksheet, another error will be thrown.
'You can add error-handling for this case, similarly as above.
With valuesSheet
.Range("Value1") = macrosSheet.Range("Value1")
.Range("Value2") = macrosSheet.Range("Value2")
.Range("Value3") = macrosSheet.Range("Value3")
End With
End If
End Sub

Heya this is probably simple but I cannot figure out what is wrong.
I am trying to do .find for a specific date and change that selection to a user input date.
I have a userform to select a date from a combobox (date1_cbo). The combobox source is linked to dates on a worksheet (Backend). There is a textbox below for writing the new date to change it to (date1_txt). I keep getting an error
object variable or with block variable not set.
I have tried a few options without any luck here is my code:
Dim selection As Range
Dim check As Boolean
'input box validation
check = IsDate(date1_txt.Value)
If check = True Then
'find cell matching combobox
With Worksheets("Backend").Range("A1:A500")
Set selection = .Find(date1_cbo.Value) 'this is the problem
selection.Value = date1_txt.Value
End With
Else
End If
Interestingly .Find returns the range or Nothing. however because the combobox is linked to the cells I am searching through this should never return nothing... I dont understand why the error is occurring.
a variable named as 'selection' is bad coding practice but totally legal. Don't use such names for the sake of clarity.
Error 91 is caused when you are trying to read a property( .value) from null object. your selection variable is null cause date formats on the sheet and combobox are different.
Just convert to date before attempting to find it in sheet.
Set selection = .Find(CDate(date1_cbo.Value)) '/ once again, selection is valid but bad name for variable.
You are using a variable named Selection. VBA uses it as well. Rename your variable to anything else, rewrite your code and it should work. Even Selection1 is quite ok:
Public Sub TestMe()
Dim selection1 As Range
With Worksheets(1).Range("A1:A500")
Set selection1 = .Find("vi")
End With
If Not selection Is Nothing Then
selection1.Value = "some other value"
End If
End Sub
To change multiple values with Find() as here - A1:A10, then some possibility is to do it like this:
Public Sub TestMe()
Dim myRng As Range
With Worksheets(1).Range("A1:A500")
.Range("A1:A10") = "vi"
Set myRng = .Find("vi")
If Not myRng Is Nothing Then
Do Until myRng Is Nothing
myRng.Value = "New value"
Set myRng = .Find("vi")
Loop
End If
End With
End Sub
It is a bit slow, as far as it loops every time and it can be improved, if the range is united and replaced at once.
I have a macro (Excel 2010) and a textbox with name CSVExport in the sheet. Here is the code:
Option Explicit
Sub Export()
Dim exportRangeStr As String
Dim currSheet As Worksheet
Set currSheet = Worksheets("Skill Experience")
exportRangeStr = currSheet.CSVExportRange.Value
Debug.Print 1
When I try to run it I get an error "Compile error: Method or data member not found" with .CSVExportRange highlighted. But when I comment that line out and set a breakpoint in the last line I see in the watch window that currSheet has the CSVExportRange field and all its data properly stored. What am I doing wrong?
The generic Worksheet class does not have a CSVExportRange member. You either need to declare your currSheet variable as an Object, or using the specific code name for the worksheet in question (or the relevant interface if you've set one up).
In an attempt to retrieve constants from each worksheet in some reporting workbooks I use, three years ago I wrote some code that gets included in each worksheet. Here's an example of the code:
Option Explicit
' Determine the type of worksheet
Private Const shtType As String = "CR"
Public Function GetShtType()
GetShtType = shtType
End Function
In other code that gets the values from the worksheets for processing, the following section of code is used, where 'wksToCheck' is the worksheet in question. This code is stored in a personal macro workbook, not in the workbook with the worksheet code:
' Get the sheet 'type' if it has one
On Error Resume Next
shtType = wksToCheck.GetShtType()
If Err.Number <> 0 Then
' We do not have a type
shtType = "Unknown"
Err.Clear
End If ' Err.Number...
On Error GoTo Error_BuildTemplateWbk
My problem is, I use the code above to process workbooks several times a week, and I have for the past three years. Now, I am trying to write some new code with the above block to process the report workbooks in a different way. However, when I run code with the above block now, I get a 'Method or Data Member Not Found' error on the '.GetShtType()' portion of the code. I cannot compile the code and of course, consequently, the code doesn't work. I have tried adding the worksheet code to a worksheet in the macro workbook to see if that would fix the problem. It hasn't. Does anyone have any ideas? I am running Excel 2013 on a Windows 7 PC. Any ideas?

Using late-binding, should avoid the error, Dim wksToCheck As Object, but you'll lose the intellisense.
If you're open to alternatives, you may have better luck simply using the CallByName function, or using worksheet's CustomProperties.
Using CallByName preserves backwards compatibility with your older workbooks if needed:
shtType = CallByName(wksToCheck, "GetShtType", VbMethod)
Or, using CustomProperties instead of a custom method, in your worksheets:
Private Sub Worksheet_Activate()
Const PropName$ = "ShtType"
Const ShtType$ = "CR"
On Error Resume Next
Me.CustomProperties(PropName) = ShtType$
If Err.Number = 13 Then
Me.CustomProperties.Add "PropName", ShtType
End If
End Sub
Then,
' Get the sheet 'type' if it has one
On Error Resume Next
shtType = wksToCheck.CustomProperties("ShtType")
If Err.Number = 13 Then
' We do not have a type
shtType = "Unknown"
Err.Clear
End If ' Err.Number...

I have to run a set of code related to worksheet "wins", but only if that worksheet exist.
Please share a code to check the availability of sheet "wins". If worksheet "wins" exist, then only I want to run that set of code, else I want to skip executing that set of code and move to next line of code.
You could use On Error Resume Next to skip the errror which occurs if you try access a not existing worksheet and assigning it to a object variable. So if the worksheet does not exist, no error occurs but the variable is Nothing. If the worksheet exists, then the variable is not Nothing.
Example:
Sub test()
Dim wsWins As Worksheet
On Error Resume Next
Set wsWins = ActiveWorkbook.Worksheets("wins")
On Error GoTo 0
If Not wsWins Is Nothing Then
MsgBox "Worksheet wins exists."
Else
MsgBox "Worksheet wins does not exist."
End If
End Sub
Axel's answer will work nicely. Some people prefer not to use error throwing to test if something exists. If you're one of them then I use the following quite a lot in a Utility module. It'll work for Worksheets, Charts, etc. (basically anything that's a collection with a 'Name' property):
Public Function ExcelObjectExists(testName As String, excelCollection As Object) As Boolean
Dim item As Object
On Error GoTo InvalidObject
For Each item In excelCollection
If item.Name = testName Then
ExcelObjectExists = True
Exit Function
End If
Next
ExcelObjectExists = False
Exit Function
InvalidObject:
MsgBox "Developer error: invalid collection object passed in ExcelObjectExists."
ExcelObjectExists = False
End Function
You can call it like this:
If ExcelObjectExists("wins", ThisWorkbook.Worksheets) Then
What I want to achieve:
I want to assign copy of a worksheet to variable, for later use.
What I tried and results
First : The code below works fine. Something like this I would like to achieve, but using worksheet.copy.
Sub DuplicateSheetRenameFirst()
Dim wsDuplicate As Worksheet
Set wsDuplicate = Worksheets.Add
wsDuplicate.Name = "Duplicate"
End Sub
Second : Using the copy method, creates a worksheet in current workbook, but generates a Runtime error 424 - Object required.
Sub DuplicateSheetRenameSecond()
Dim wsDuplicate As Worksheet
Set wsDuplicate = Worksheets("Sheet1").Copy(after:=Worksheets(Worksheets.Count))
'above line : runtime error 424 object required, but the sheet is created
wsDuplicate.Name = "Duplicate"
End Sub
Third : Creates a worksheet in new workbook (so creates book, then sheet), but still generates the same Runtime error 424 - Object required.
Sub DuplicateSheetRenameThird()
Dim wsDuplicate As Worksheet
Set wsDuplicate = Worksheets("Sheet1").Copy
'above line : runtime error 424 object required, but the sheet is created in new workbook
wsDuplicate.Name = "Duplicate"
End Sub
Workaround : I can modify any of the second or third way to at first copy the sheet and then set the variable to activesheet, but I was wandering if there is a one step way of doing this. I'm not sure if this would work all the time, since the activesheet may not be the one just copied, maybe.
The Question:
Is there a simple (one step) way to store the copy of a worksheet in a variable? Preferably without errors or without filtering the error with error handler.
This is maybe ok?
Sub copySheet()
Dim ws As Excel.Worksheet
Excel.ThisWorkbook.Sheets("Sheet1").Copy After:=Sheets(1)
Set ws = Excel.ThisWorkbook.ActiveSheet
End Sub
It is unfortunate that in this case you need to use an Active... object. Generally it is good practice to avoid Active... objects.
You cannot do this though as the method .copy is not returning an object of the worksheet class:
Sub copySheet()
Dim ws As Excel.Worksheet
Set ws = Excel.ThisWorkbook.Sheets("Sheet1").Copy(After:=Sheets(1))
End Sub
Some further explanation is in this previous post:
Why does Worksheet.Copy not return a reference to the new workbook created
In MSDN it is not altogether obvious that the method returns nothing:
https://msdn.microsoft.com/EN-US/library/office/ff837784.aspx
...but in your friend Excel's Object Explorer it is more obvious. If it returned a worksheet object then by the arrow would read:
Sub Copy([Before], [After]) as Worksheet
