Hi i am very new to C#. I downloaded somebody's project from some site. he had made enhanced glass buttons. the project also includes a dll file. I need to know how to add this file to my project and run the project on any pc without adding it everytime!

Add reference of dll files in ur project and right click on added dll and set property copy = true. this help to preserve copy of dll in project so not need to again copy dll file externally
