As Star Trek's Mr. Scott used to say, "The right tool for the right job." In this case I think you would be better served using Visual C++ as your development language. Your primary concern here is taking temperatures in real-time and saving the results. You aren't really doing any data manipulation, so VFP's power won't be of any use. What will be of benefit to your application, however, will be the faster speed and a smaller footprint that VC++ can provide.
