Hi, Richard:

Thanks a lot for your articles. I bought a few your tech books about
C++/ATL and COM in the past decade. Great works!

It is a great undertaking, but I can't find anything knew in there, that I
can't already find on MSDN.

On a more constructive note.

Event log section fails to mention that code must be running as a member of
Administrators group for it to create Event log source. This is especially
important for code like the following sample parts to work:

....
if (EventLog.SourceExists(sourceName))
{
EventLog.DeleteEventSource(sourceName);
EventLog.Delete(logName);
}
....
if (!EventLog.SourceExists(sourceName))
{
EventLog.CreateEventSource(sourceName, logName);
....

Administrator membership is also a reason for installer to create event log
sources and performance counters instead of doing it from the main
application.

Performance counters section is weak. A not so obvious problem of counting
time span is not covered at all and it is part of many performance counters.
AverageTimer32 example could be quite valuable.

Multi-instance performance counters can easily run out of memory.
Interesting topic...
