I never actually did any DLL calls in the PDA module and I never tested it in .net (the only device I got my hands on so far had CE.net 4.1 and the EXE didn't run), but as far as I know, if you expose the functions correctly in the DLL, LV should be able to see them. One thing to note about working with the PDA module is that you need to have the source code for the DLL before you can build the application for the PDA. Try searching the site for more details about using the module with CE.net.
