There is no way to do this from the command line. What you might be
able to do is create a 'starter' application that starts the first one
and install that on the client machine. Then you could use your pocket
pc to start the 'starter' application which would in turn start the
main application while simulating a depressed shift key. The code at
http://www.mvps.org/access/api/api0068.htm uses automation to run an
access app bypassing startup. Your 'starter' application could use
this code along with something like the following to invoke it:
Sub StartWithShift(strMyApp as String)
Static app As Access.Application
Set app = fGetRefNoAutoexec(strMyApp)
End Sub
With this approach, your application will start in a separate window
via automation as though you had depressed the shift key and will live
until you close it manually or until you close your 'starter'
application.
