Hi,
In CList , we can use variable of type POSITION to
GetAt(),SetAt(),etc. Now if we use it like this:

funtion1(POSITION currentpos, POSITION& previouspos)
{
};//in function1 return the value of previouspos

funtion1 returns the value of previouspos, can I use it to
GetAt(previouspos) the element in another function2:

function2()
{
...
mypoint=mysegment.mypointlist.GetAt(previouspos);
...
};
...
does it worked?

I mean , wether the position of CList is soly and fixed when the
CList
created?

Yes, the POSITION returned by function1 can be used by function2, provided
the list hasn't been altered.

The problem is that only on SOME Vista installations is there a problem.
Others are
working fine. And he's got at least one XP SP1 site that has a similar
problem. The
manifestation of the problem is that the WH_JOURNALPLAYBACK is not
working.

I've seen some discussion here, but in this case, because he has Win16
apps, manifests are
probably not going to be the answer.

He believes that all the Vista systems are "out of the box" but a couple
are from
different OEM vendors, and he conjectures that they are delivering a
not-quite-OOTB
configurations, but has no way to figure out what has gone wrong, or what
policies need to
be examined or edited to enable correct execution.

I don't even have a version of Vista installed, so I can't help him. Any
suggestions, or
pointers to appropriate articles, would be a big help.
