As with all of the VSFlex and other ComponentOne controls, this baby just rocks! I spent a full day trying to get another competitor's product working and couldn't. In just over 5 hours, I had the full-featured demo up and running against my real-time data. This tool is NOT for amateurs or beginners. It requires a good deal of study to learn, but it has a great feature set. The documentation is light and could most definitely be better - more examples are needed. It does include a number of really excellent VB and other code samples you can use to get started. This is my next purchase.
