Version: Visual DataFlex Personal 12.0.91.8
Cons: It's a bit of an obscure programming lanuage, a mix of "styles". The data access language is very primitive, the database structure hardcoded into your program. Its native "database" is nothing more than a set of indexed files and it's slow and unreliable. In order to connecting to a real database takes a so-called "connectivity kit". For these connectivity kits, as well as for every copy of your program you sell, you need to pay license fees to the manufacturer. You can use COM-objects if you're lucky, but .Net is not supported and it doesn't look like it will be supported any time soon. Please be very careful before you invest thousands of hours of development time and choose a language with a decent licensing scheme and with a future. Just get your free copy of VB.Net

Version: Visual DataFlex Personal 12.0.91.8
Pros: I'm always open to new languages, and Visual DataFlex seems intuitive and easy to use. The IDE seems very stable and easy to work with. There are a lot of wizards and automatic code generation tools that really help speed application development along.
The automatic database connectivity is nice, but it's nothing out of the ordinary now, since other languages have had that ability for quite some time. Also, field validation is nice since it's set up once and available anywhere a field is available on screen. However, this has been available with other languages like .Net, for a while.
Cons: Unfortunately, the free edition is limited to 5 concurrent users, which is a problem with any database application, unless it's single user. If it's single user, you might as well use Access with VBA.
If you happen to purchase the full version, in order to use the application on any other machines, you need to pay runtime license fees. Not good. This really limits who you can sell the product too.
Using COM/ActiveX components seems to work, except when you get into really complex ones. Out of the 5 I tried, I could only get 2 to work well without errors.
The IDE looks nice, but the developed applications look like any other run of the mill software, which isn't necessarily a problem, but it is a drawback when you can't change much of that, especially with the grids.
On a whole, it's not very reassuring that the language is a few steps behind a lot of the mainstream languages. They just recently added the ability to use structures and proper arrays. And by recently, I mean a year or two. When mainstream languages have supported this for the last 10 years, it's not a good thing to see Visual DataFlex just now catching up.
Before sinking a lot of money into this environment, investigate other languages like C# or VB.Net. Application development time is about the same, but you won't have to deal with language restrictions or runtime licensing.

Version: Visual DataFlex Personal 12.0.91.8
"Easy to find in even for rookies - great to work with!"
Pros: If you have an idea of what database programming is about you wont have difficulties to work with this software. Great possibilities and very reliable in use. And database driven webservice development is even easier than with Visual Studio.
