    Thumbs up [RESOLVED] How to prevent/close multiple instances of Excel in VB6

    [[[[[[[[[[[[[[[[[[[ RESOLVED: SEE http://www.vbforums.com/showthread.php?t=618773 FOR MORE INFO ]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]

    Hi I'm writing a program that accesses an Excel file (just one worksheet!) and displays selected rows in a form for users to view/modify. My problem is that every time I access, use, and close the Excel file it still keeps an instance running so that when I've exited my own program I'm left with several, often INVISIBLE, instances of the worksheet that I'm unable to close without the Task Manager. Is there anyway to avoid this? Why doesn't it just close and stop running with my code? Also, I've seen where some programmers are declaring their Excel apps, worksheets, and workbooks as OBJECTS, rather than as I have, below. What's the difference?

    'declarations
    Dim xl As New Excel.Application
    Dim xlsheet As Excel.Worksheet
    Dim xlbook As Excel.Workbook

    'body of code

    'disconnect from & close worksheet, workbook, Excel application
    Set xlsheet = Nothing
    xlbook.Close savechanges:=False 'depending on what i'm doing, sometimes True
    Set xlbook = Nothing
    xl.Quit
    Set xl = Nothing

    Thank You!

    I take it that the Excel file is an existing Excel file, right ? How are you creating the Excel application object ??
