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. Ross.

Paul ----- Original Message ----- From: Ross Levis <mailto:[email protected]> To: [email protected] Sent: Saturday, May 01, 2010 4:49 AM Subject: [DUG] UAC control 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.
