[DUG] UAC control

Sat May 1 23:17:48 NZST 2010

Named pipes won't be blocked by a firewall, I'm just concerned about the
Vista and Win7 security system which blocks memory sharing between elevated
and non-elevated programs.

I was thinking of simply using a text file to send data back and forward if
that is the only other option.

I'll investigate named pipes.  Hopefully I can send a fixed record structure
this way.

If you can get it working using sockets, then this should work also.

I've never seen named pipes blocked by a firewall

Can this work when one app is elevated and another is not?  I had problems
with memory sharing via a virtual memory mapped file not working because of
this.

A listening socket is normally blocked by firewalls and virus scanners.

Use named pipes instead.

I'm back to this subject again.

I released a new version of my software using the TCP server/client method
to communicate with a separate elevated app where I do my HKLM writing etc.
But this is turning out to be a nightmare with firewalls.

The proper method is to write a DLL which does something to trigger elevated
privileges.  I'm hoping someone could send me example DLL code I can use to
do this, and the code to call it from my app.  I'm not experienced writing
and using DLL's.

Many thanks,

Ross.
