help.<o:p></o:p></SPAN></P>

<P class=MsoNormal><SPAN style="COLOR: #1f497d; FONT-SIZE: 12pt"
lang=EN-US>Since Vista came out I’ve been using a small program I wrote with a
manifest to give it elevated privileges, so I can write to the HKLM registry
when requested by any of my applications. I use a shared memory
component (memory mapped file with no file) to communicate between an app and
the small program which is loaded when required.<o:p></o:p></SPAN></P>
<P class=MsoNormal><SPAN style="COLOR: #1f497d; FONT-SIZE: 12pt"
lang=EN-US><o:p> </o:p></SPAN></P>
<P class=MsoNormal><SPAN style="COLOR: #1f497d; FONT-SIZE: 12pt"
lang=EN-US>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.<o:p></o:p></SPAN></P>
<P class=MsoNormal><SPAN style="COLOR: #1f497d; FONT-SIZE: 12pt"
lang=EN-US> <o:p></o:p></SPAN></P>
<P class=MsoNormal><SPAN style="COLOR: #1f497d; FONT-SIZE: 12pt" lang=EN-US>So
it appears I need an alternative method. I could use the elevated DLL
method, but this seems complicated. I’m not an advanced
programmer. It’s a bugger as I spent quite a bit of time getting this
working well when Vista first came out. I would prefer to continue using
the small app, but it appears I need some other method for sharing text
between 2 processes of different elevations. Does anyone know if this is
possible?<o:p></o:p></SPAN></P>

<P class=MsoNormal><SPAN style="COLOR: #1f497d; FONT-SIZE: 12pt"

elevated program does not work anymore.<o:p></o:p></SPAN></P>
