In the code below, on the 2nd line of code where it says: Set oExcel =
GetObject(, "Excel.Application")
What does the "," in (, "Excel.Application") do? WHy is there a comma
there?

On Error Resume Next
Set oExcel = GetObject(, "Excel.Application")
On Error GoTo 0
If oExcel Is Nothing Then
'Excel wasn't open - open a new one
Set oExcel = GetObject("", "Excel.Application")
End If

Check the 'GetObject Function' (w/o the quotes) in XL VBA help.

It looks strange doesn't it.
GetObject has two optional arguments. The comma is just a quick way of
getting to the second argument.
You could just as easily write: Set oExcel =
GetObject(Class:="Excel.Application") but it's longer to type and read.

Todd,

This is because GetObject has two parameters, pathname and class. You can
use it by specifying the pathname of a file, or the application class, or
both. If you omit the form er, you must have the latter, a class.

By the way, GetObject is not late binding. You can use GetObject with late
or early binding. What makes it late or early is whether a reference to the
type library is set or not.
