Excel Opens Multiple Times

I open a spreadsheet I want to work with when my program loads using the code below. Each time i execute my code to perform some calculations on the spreadsheet a new instance of Excel is opened. How do i stop a new instance of Excel opening when I execute my code?

Thanks.

Code:

---

Private Sub Form_Load()
oXLApp.Workbooks.Open FileName:=App.Path & "" & "OSPREY.xls", Notify:=True
oXLApp.Sheets("LBOP-New Capital p.a" ).Select 
End Sub

When you want to open excel, you will need to check that
a) Excel is open - if not open it
b) that the workbook you want is open - if not open it

Then you can use the reference to the workbook (b) which will not reopen the workbook again.
