I save different data in Excel-files from my VB-application.
I access Excel through the following object variable:

Dim xlApp as Excel.Application
Set xlApp = CreateObject("Excel.Application")

Is there a way to determine whether xlApp is instantiated or how many instances have been created?

Unfortunately IF xlApp = Nothing Then ... doesn't work.

I want to make sure, that I can close all the Excel-instances in case of an error.
