Function foo1(FilePath As String) As Workbook
For Each x In Workbooks
If x.FullName = FilePath Then Set foo1 = x: Exit For
Next
If foo1 Is Nothing Then Set foo1 = Workbooks.Open(FilePath)
End Function

Function foo2(WS As Workbook, SheetName As String) As Worksheet
For Each x In WS.Worksheets
If x.Name Like SheetName Then Set foo2 = x: Exit For
Next
If Not foo2 Is Nothing Then foo2.AutoFilterMode = False
End Function
