Creating a DLL

Is it possible to use JUCE to create a DLL?

Thank you!

Why not? JUCE is just library and i don't think using any library exclude compiling into dll. Besides JUSE is use to write some vst plugins so for sure you can get an dll. I'm just an beginner in c++ so i can't tell you exactly what to do, but generally you can set this in project>proerties>configuration properties>general>configuration type. :)
