Excel won't release database

[Honsolo]

Can someone look at this code and tell me why it won't release the database after it fills the flexgrid and I close excel. I have tried everything.

Dim xapp    As Excel.Application
Dim xsheet As Excel.Worksheet
Dim xlWB        As Excel.Workbook
       
    Set xapp = New Excel.Application
    Set xlWB = xapp.Workbooks.Open("C:\Program Files\Denali\Databases\Databasesloc.xls")
    Excel.Application.Visible = False
    Clipboard.Clear
    Set xsheet = xapp.Worksheets(1)
    
    With xsheet
    .UsedRange.Copy 
    End With
       
    With MSFlexGrid1
        .Redraw = False     
        .row = 0            
        .Col = 0
        .RowSel = .Rows - 1 
        .ColSel = .cols - 1
        .clip = Replace(Clipboard.GetText, vbNewLine, vbCr) 
        .Col = 1           
        .Redraw = True         
    End With
 
       xapp.DisplayAlerts = False 
       Clipboard.Clear
       MSFlexGrid1.Rows =xapp.ActiveWorkbook.ActiveSheet.UsedRange.Rows.count + 1
 
   'Trying to close Excel here
 
   Set xsheet = Nothing
   xlWB.Close SaveChanges:=False
   Set xlWB = Nothing
    xapp.Quit
    Set xapp = Nothing
    Excel.Application.Quit
