I rearranged your code slightly and I don't get excel process still running
when I do it this way:
Private ExcelApp As Excel.Application
Private oBooks As Excel.Workbook

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As _
System.EventArgs) Handles Button1.Click
ExcelApp = New Excel.Application
ExcelApp.Visible = True
oBooks = ExcelApp.Workbooks.Open("C:\Book1.xls")

End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As _
System.EventArgs) Handles Button2.Click

ExcelApp.Workbooks.Close() '(or Wb.Close)
ExcelApp.Quit()

End Sub

HTH,

is still running. Can someone help?

Private ExcelApp As Excel.Application
Private oBooks As Excel.Workbook

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
CreateObject("Excel.Application")
Wb = ExcelApp.Workbooks.Open("C:\Book1.xls")

ExcelApp.Workbooks.Close() '(or Wb.Close)
ExcelApp.Quit

End Sub

I don't get why even after ExcelApp.Quit, Excel.exe still appears in task
manager...
