Dim FN As String = Server.MapPath("\esmp\temp\" & Session.SessionID & ".xls") Dim xl As New Excel.Application Dim wk As Excel.Workbook = xl.Workbooks.Add() xl.Cells(2, 2) = "its ok" wk.Close(SaveChanges:=True, FileName:=FN) wk = Nothing xl.Quit() xl = Nothing ------------------------------- that was the coding I wrote in the button click event. It does work fine...but it is creating a separate process every time, the event is fired...and the process from task manager could not get deleted automatically. If I click on button 5 times....5 processes named as "EXCEL.EXE" are staying in the processes of TaskManager. So, How to make the process to close byitself after the completion of its work.
