Today I worked again on DTLoggedExec. I've been able to add the ability to log properties with DTS Expressions associated. This allows the log to show and report properties values in additions to the already present ablity to log variables values.
I'm sure you'll find this feature really helpful if you're using DTS Expression (as you should do) to add flexibility to your SSIS Packages.
The DTLoggedExec that will contain this new feature will be the version 0.1.1.0.
