Let me prefix with, I've done many VB6 and ASP applications that read
from/write to Excel and have never had a problem. I'm not a beginner at
this...

I have created my first .NET Windows application that reads from Excel 2000
and writes to a tab file. I am using the code below and when stepping
through the appExcel.Quit() is executed. However, the EXCEL.EXE process
still runs and will run until I close the .NET application I've built. This
happens in both DEBUG and RELEASE compilations.

Try
appExcel = New Excel.Application()
... coding tasks ...

Catch ex As Exception
... error tasks ...

Finally
appExcel.Quit()

Any ideas why Excel is not being released after the quit? I even tried
adding GC.Collect() to see if it helps to force the Garbage Collection to
release appExcel.

Thanks, in advance.
