Attached (now in the WIKI) is a VB6 wrapper that is a bit different to most in that it binds to the sqlite DLL at runtime.
Consequently, all you need to do is put this in your path along with the sqlite3.dll (or sqlite.dll if you want to use 2.8.x) and it sorts out the calls at runtime. The DLL also contains a Java JNI implementation that does the same thing. As with the VB6, you can call it from Java without having to worry about re-creating the DLL for each new release of sqlite. The zip contains VB6 and Java examples. As with sqlite, it's free and if you want the source code for the DLL I'll send it anyone that's interested.
