You create a LabVIEW DLL with the application builder. It is an add-on for U$995 or comes as part of the Professional version of LabVIEW. A DLL will be a bit smaller though you can accomplish about the same thing by saving copies of your VIs without diagrams. Make sure you save a COPY because once a VI is saved without a diagram, the daigram is permanently gone and you'll nver be able to edit it again. You might notice a slight difference in speed but all VIs are compiled and not just DLLs and EXEs.
