Re: ShellExcute for non EXE files

OK, there are several issues here.  First, the question is how to send commands to a
command window.  This is going to depend on the interface you are using.  For example,
when we used a product called Reflection, which is philosophically similar to the idea of
a 3270 emulator (in fact, it can be a 3270 emulator as one of its many emulator modes),
the vendor supplied a DLL that accepted text strings that were sent as commands, and a
callback mechanism from that DLL that send received text to our app.  

So if you are calling ShellExecute, you shouldn't be invoking a service, but should be
invoking a GUI app running in your own login session.  If that has to start a service and
send and receive information from the service, then it might do so.  Note that starting a
process in a different account (thus limiting its rights to the rights possessed by that
account) is not at all the same as starting a service.  So what you should be looking for
is whatever you need as part of that WinHLLAPI library you refer to.  

Are you really sure this is starting in a different desktop?  While it might be, it is
also possible that it is simply Just Another App.  Where are there specifications about
this component that we can read about?
