Excel workbook closed through vba code still running in the process

[pallopammy]

Through excel VBA i'm opening the workbook and closing, thus quitting the excel application. But it is still running in the Task manager, which prevents my addin to work properly. part of the code is as follows

   Sheets("Sheet1").Select
  
    Finalrow = Cells(Rows.count, 1).End(xlUp).row


    
LastCol = Cells(1, Columns.count).End(xlToLeft).Column


   
   
   
   '__________________________________________________
   
   
 'Dim oExcel As Excel.Application
   'Dim oBook As Workbook
   'Dim oSheet As Object
  
   
   Set oExcel = New Excel.Application
  


   Set oBook = oExcel.Workbooks.Open(ADDIN_PATH & "\" & "hello.xls")


   Set oSheet = oBook.Worksheets(1)
   


   


   


sCellName = "--Select--"
   
   oSheet.Range("A3").Value = "Name"
   
    If (ComboBox1.Value = "--Select--" Or ComboBox1.Value = "") Then
    MsgBox "Please Map the name field"
    'Else
    'oSheet.Range("B2").Value = ComboBox1.Value
      Exit Sub
   End If
   
   
    'oSheet.Range("B2").Value = ComboBox1.Value
 
   
 
   


   
   
   
   oSheet.Range("B2").Value = ComboBox1.Value
   
      If (ComboBox2.Value = "") Then ComboBox2.Value = sCellName
   


oBook.SaveAs ADDIN_PATH & "\" & "hello.xls"
oBook.Close
oExcel.Quit
Set oExcel = Nothing


   
   
   MsgBox "Your current setting has been saved"
   SettingForm.Hide
End Sub
