[DUG] IPC with an elevated program

[Conor Boyd]

I went down the elevated COM DLL route that you mention about 6 months
ago, and it works very well.
 
There's a post on StackOverflow here
(http://stackoverflow.com/questions/923350/delphi-prompt-for-uac-elevati
on-when-needed/923551#923551) that I contributed to that should have the
info you need.
 
There's a link to a PDF there that was helpful along with the link that
I posted.
 
I'm busy in training this week, but have a look at the links, and if
you're still having trouble, drop me a line, and I'll see if I can find
a few mins here and there to help.
 
C.

I don't really want global shared memory.  The reason for the small app
is to have the UAC prompt appear when I need to make changes to the HKLM
registry, which is very rare.  There is a standard way to do this but it
sounds difficult.  Some sort of DLL needs to be created I believe.

If you want to to use shared memory in Vista and above its best to write
a service to create global shared memory that all users can access. The
key here is global shared memory and with the right security bits set.
Best to Google global shared memory for more info.

 

heres one link I found that maybe helpful

 >> But since Vista SP1 or SP2, Microsoft appears to be preventing
shared memory access between an app with standard privileges and one
with elevated.  I've been   wondering why some users have been reporting
odd problems and this appears to be it.
