According to THIS CIN is no longer support in LabVIEW you can use Call Library Function Node.

If you still are going to use old CIN instead of standard DLL you may take a look at this post: http://forums.ni.com/t5/Discussions-au-sujet-de-NI/Ins%C3%A9rer-du-code-C-dans-un-VI-LabView/m-p/314... There I have explained the steps to get CIN technology working in new LabVIEW versions.
