Again, Thank you for your time and advice. I am still figuring out VS so that doesn't help. I believe I have done what you suggested. Here is the command line generated by VS. I couldn't find any reference to "_DEBUG" but added it with "SQLITE_DEBUG" for undefining in properties. I even created a brand new project and still encountered the same problem. Took a completely different project that works and replaced the file contents and still the same issue. Oddly enough I have another project that has started failing with weird errors that worked fine. Nothing to do with SQLite but just odd. Not sure what else to try. I never messed with any of this stuff because it worked fine as it was when I created the project and all the months since. Wish I knew why it popped up now??? Happy for any more suggestions but feel like I am taking up too much of your time. I guess I will just have to post DEBUG versions. Maybe it will start working again, correctly, like it stopped. Thanks again.
