using Excel keeps adding books

while creating Excel files in vb.net, all is fine, except when I want to close my PC and there are many popups to save or delete "bookx.xls". How do I prevent these blank books from being made??

THanks,

Well that all depends on what your code is doing.

this is basically the code I use to create it, then as I create data, I open and add sheets to it and close again.. so how do I stop it from creating ghost books???

vb Code:

Public Sub Create_Excel_File(ByVal sPath As String, ByVal sName As String)
 
        Dim pExcel_App As Excel.Application
        Dim pExcel_Wkbook As Excel.Workbook
        Dim wkbSheet As Excel.Worksheet
 
        Try
 
            pExcel_App = New Excel.Application
            pExcel_Wkbook = pExcel_App.Workbooks.Add
            '== add worksheet to file
            wkbSheet = pExcel_Wkbook.Worksheets.Add
 
            Dim sOutExcelPath As String
            sOutExcelPath = sPath & "\" & sName
            pExcel_Wkbook.SaveAs(sOutExcelPath)
 
            pExcel_App.DisplayAlerts = False
            pExcel_App.ActiveWorkbook.Close(SaveChanges:=True, Filename:=sOutExcelPath)
            pExcel_App.Quit()
 
        Catch ex As Exception
            MsgBox("ERROR: " & m_Current_Address & " -  Create Excel log file for - " & mDistrictName & " - " & ex.Message)
        Finally
            pExcel_App = Nothing
            pExcel_Wkbook = Nothing
            wkbSheet = Nothing
        End Try
 
    End Sub
