What's the right way to do this? (threading/AppDomains)
Posted by Mountain Bikn' Guy at 11/4/2003 8:45:10 PM
I need some advice on this. I am working on a fairly complex calculator app (C#) with lots of functions (and these functions in turn use math functions from an unmanaged C DLL). A calculation takes a lot of time (up to hours), and should run on a separate thread from the one that the GUI uses. Th...more >>

performance counters as event sinks in Enterprise Instrumentation?
Posted by barnaby_morris NO[at]SPAM hotmail.com at 11/4/2003 4:23:25 PM
I have been investigating the Microsoft Enterprise Instrumentation Framework as a flexible logging solution for our software.

Sorting a Directory by Modified Date?
Posted by David Cardinal at 11/1/2003 10:13:45 PM
Every method I can think of for sorting a directory by file modified date is very slow, as it appears that the .NET libraries need to do an Open & GetInfo on every single file entry.
