SolidWorks API Sample Projects

I've been reading the API help to try and automate somefunctions we do and I was looking through the API sample projectsand downloaded some of them but I'm not sue how to use them??

The macro's i understand, but the addin's are the ones I'm confusedabout. When I unzip the zip file there is about 10 files in there.

Has anyone used these and if so, what do I need to do to use them?

Thanks for the help once again.SolidworksApi macros
