Different web browser's don't change the content of a website.

It's only a
one time fee for the commercial license, which is only $30 where buying DBPro costs more than twice as much ($70).
Quote: "gdk can use other stuff (can't remember what it's called) but DBPro can only use plugins."
It's not DarkGDK that's using anything, it's your Visual C++ projects that will use the DarkGDK library. Along with that, you can use most of the DarkBasic Pro plugins as C++ libraries for Visual C++ alongside DarkGDK. Plus all the many, many other libraries that can be used with Visual C++.
Basically, I'd say, to get the hang of DarkBasic's syntax and how it works, spend as much time as you can with the Free Trial of DBP and follow as many tutorials as you can. Then, start learning C++ with Visual C++ 2008 Express Edition and follow beginner's tutorials to learn the basics of C++. Then, just buy DarkGDK and you'll be able to use it with no problem.
