What type of code version protection is National Instruments using? I want to protect the versions of codewriting I do in CVI, so incase I hose a program, I can always back up a verson or two. So MS Visual Source Save requirments are: "SCC-compliant" or "SourceSafe compliant." http://msdn.microsoft.com/ssafe/ >> http://msdn.microsoft.com/ssafe/technical/documentation.asp
