Sorry for the late reply... Well, I can not use the SQLite 64bit DLL in a 64bit environment with a 32bit application. So, this answer your questions, at least as SQLite DLL is concerned. What I am trying to find out is the speed difference from both 32bit and 64bit environment. I will have to look deeper, but, there are definitely differences. I will come back later and let you know the outcome, if I can find it. Thanks for your support. jos?
