Starting and Quitting Excel

[George]

I've seen questions of how to check if Excel is already running.

If the user has already started Excel normally; call this Excel(User),
then vb.net code runs:
myXL = CreateObject("Excel.application")

Does this new instance of Excel(VB) work completely separate from the
Excel(User)? If yes, why is there a need to check if Excel is running?

When ending the Excel(VB), is there a way to quit this instance and
leave the Excel(User) instance if it's still active?

Thanks,
George

Did you have a look at the articles about Excel automation at the
Microsoft support site?
