Wrote a little tool to add timestamps to files, meant to be used in scripting when processing tonnes of files to make them sortable and batch processing them or finding files with System.IO.Directory.Getfiles() with Sort set to true.

Software development
Created EventlogRT. A console app that dumps out Eventlog entries as they appear in either the System, Application or Security evenlog.

Requires administrative privileges to dump out Security log entries, System and Application entries does not require these privileges.

Demo tool, not open source. 64 bit binary, won't run on 32 bit systems.

So, i wrote NetEnum a while ago, can barely keep track of my smaller projects. Anyway, It logs network connections, states (SYN/FIN etc). Useful for doing standalone monitoring of processes etc... not very advanced but logs are quite detailed. This is an early test-bed version of a new project that I'm working on right now.
