It seems a normal question and I have searched and tried many suggestions here but the error persists. I want to copy a "case1" sheet from current workbook to an existing workbook(file name is "workbook2.xlsx", it has a worksheet named "case2"), then save the workbook and close it. Sometimes it works well, but most of the time I kept getting the same error. In fact I did not change any code so I don't know where went wrong.
The error shows "The object invoked has disconnected from its clients". It always breaks in the same place:
ThisWorkbook.Sheets("case1").Copy Before:=ActiveWorkbook.Sheets("Case2")
Sub CopySheet()
Application.ScreenUpdating = False
Application.DisplayAlerts = False
'open existing "workbook2.xlsx"
Workbooks.Open filename:="c:\workbook2.xlsx"
'copy a sheet named "case1" from current workbook to "workbook2.xlsx" which already has a sheet named "case2"
ThisWorkbook.Sheets("case1").Copy Before:=ActiveWorkbook.Sheets("Case2")
'close "workbook2.xlsx"
Workbooks("workbook2.xlsx").Activate
ActiveWorkbook.Close SaveChanges:=True
Application.ScreenUpdating = True
Application.DisplayAlerts = True
End Sub
