We are trying to control child processes of our main process by

viewed using Process Explorer and looking at tyhe Process' properties -
it eithe rhas a Job tab or it does not.

Thats the background to the question, why is it assigning a job object
when I execute the app from a folder, but when executed from the
command line it does not get a job object?

According to Richter's Window's Via C++ book...

In Vista, Explorer will add processes which don't have a manifest to a
"PCA" prefixed job so that the Program Compatability Assistant can
jump in and 'help' if it crashes. To avoid having explorer add your
process to one of these jobs you need to define a manifest for the
application.

Thanks Len, I'd read that somewhere on the web too. But our exe has a
manifest! It can't run without one as it uses MSVCRT90.DLL which will not
work unless we use a manifest. There is something more to it than just the
manifest.

What was meant was probably not just "a manifest", but a manifest containing
the Vista trustInfo element, such as:

<trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
<security>
<requestedPrivileges>
<requestedExecutionLevel
level="asInvoker"/>
</requestedPrivileges>
</security>
</trustInfo>
