Hello:
Put the below code under a command button called cmdExcel: This will open Excel and open the file stated in the procedure. If you want to pick a file from an Access list box, set strXls to the selected listbox entry. Be sure to include full path name to the file. Also, in Access be sure your references are set to The Microsoft Excel 10.0 Object Library or whatever version your using.
'
Private Sub cmdExcel_Click()
'Launch Excel
Dim appExcel As Excel.Application, strXls As String
Set appExcel = CreateObject("Excel.Application")
MsgBox "Excel is running"
appExcel.Visible = True
'
'Open files here
strXls ="Your Filename complete with path goes here in quotes"
appExcel.Workbooks.Open (strXls)
Set appExcel = Nothing
End Sub
Regards
Mark
