Coding for external components...

As I read through the posts in this section I notice that some of these intruments are "powered" by a couple lines of code.
My question for those who may know, what kind of code is used to do it? Visual studio dot net? C+, C++, C#, JAVA, etc?
Just asking...
I've been learning lots of different languages in school and just thought I might be able to use this stuff I'm learning at a later date for a more practical purpose..
