Message Logger

The IW Software Message Logger arose from our frequent requirements to be able to monitor deployed applications in an unobtrusive way.

The Message Logger is a light weight native Windows application which resides in the notification area of the Taskbar, and receives and displays messages from applications. It is extremely easy to use from most scripting and compiled programming languages.

Very useful during development *and* unobtrusively collecting information after deployment on your customers’ sites.
