You can, but it's a little tricky.

Subject: [padnug] Windows Service question
Hi,
I am fairly new to dotnet and windows services so I apologize if this is
something you all have already discussed.
I need to start and stop Excel from a windows service. My service is
working
just fine reading/writing files and other basic tasks. However, when the
excel application is created, my service tries to install Excel when it
is
run as "LocalSystem". When I run it as a user with administrative
privileges
an error is returned (the error says that no error was returned but an
error
occurred). I am using C#, .NET 1.1 on windows 2000.
protected override void OnStart(string[] args)
{
Excel.Application xl = new Excel.Application (); // code stops
here,
excel application never created
// do something, exit excel, clean up
...
}
Is it not possible to start Excel from a Windows Service? I have tried
everything I can think of on the adminstration side, now I am trying to
solve this programmatically. I have this same code in another
application
and it works just fine. The UI doesn't come up and isn't needed. Has
anyone
encountered this problem or have any suggestions?
Thanks
