Hi, If you see a dll on your system, how do you discover what it is capable of doing? Here's a related question. If you are using VisualBasic or some environment and you tell the environment to include a library, are you connecting your project to a dll? Related to that, if you are using PHP, and you uncomment one of the extension lines in php.ini, assuming that doing that makes it connect to a dll, what actually is happening behind the scenes? If you answer, can you please phrase the answer in plain language? Thanks.
