In Microsoft Excel, you run a macro that copies worksheets and then places the worksheets into the same workbook from which they originated. When you do this, you may receive an error message that resembles one of the following error messages:
Run-time error '1004': Copy Method of Worksheet Class failed
Run-time error '1004': Application-defined or object-defined error

This problem can occur when you give the workbook a defined name and then copy the worksheet several times without first saving and closing the workbook, as in the following sample code:
Sub CopySheetTest()
Dim iTemp As Integer
Dim oBook As Workbook
Dim iCounter As Integer
' Create a new blank workbook:
iTemp = Application.SheetsInNewWorkbook
Application.SheetsInNewWorkbook = 1
Set oBook = Application.Workbooks.Add
Application.SheetsInNewWorkbook = iTemp
' Add a defined name to the workbook
' that RefersTo a range:
oBook.Names.Add Name:="tempRange", _
RefersTo:="=Sheet1!$A$1"
' Save the workbook:
oBook.SaveAs "c:\test2.xls"
' Copy the sheet in a loop. Eventually,
' you get error 1004: Copy Method of
' Worksheet class failed.
For iCounter = 1 To 275
oBook.Worksheets(1).Copy After:=oBook.Worksheets(1)
Next
End Sub
To resolve this problem, save and close the workbook periodically while the copy process is occurring, as in the following sample code:
Sub CopySheetTest()
Dim iTemp As Integer
Dim oBook As Workbook
Dim iCounter As Integer
' Create a new blank workbook:
iTemp = Application.SheetsInNewWorkbook
Application.SheetsInNewWorkbook = 1
Set oBook = Application.Workbooks.Add
Application.SheetsInNewWorkbook = iTemp
' Add a defined name to the workbook
' that RefersTo a range:
oBook.Names.Add Name:="tempRange", _
RefersTo:="=Sheet1!$A$1"
' Save the workbook:
oBook.SaveAs "c:\test2.xls"
' Copy the sheet in a loop. Eventually,
' you get error 1004: Copy Method of
' Worksheet class failed.
For iCounter = 1 To 275
oBook.Worksheets(1).Copy After:=oBook.Worksheets(1)
'Uncomment this code for the workaround:
'Save, close, and reopen after every 100 iterations:
If iCounter Mod 100 = 0 Then
oBook.Close SaveChanges:=True
Set oBook = Nothing
Set oBook = Application.Workbooks.Open("c:\test2.xls")
End If
Next
End Sub
Note The number of times you can copy a worksheet before you must save the workbook varies with the size of the worksheet.
To work around this problem, insert a new worksheet from a template instead of copying an existing worksheet. To do this, follow these steps, as appropriate for the version of Excel that you are running.
