Hi At the moment I'm on one side of the planet (New Zealand) and VB 4.0 compiler is on the other side (Brazil) so I can't prepare a sample project. I suspect that anything in VB that tries to open an MSJet database file would cause this problem. However, I can send you both the source and a zip of the application itself, which is a Bible concordance program, with both English and Portuguese versions. A zip file of the object code with all necessary databases can be found here: (14 megabytes) http://www.avivamentoja.org/download/verbo17.zip I'll gladly send source code or anything else that would help, just let me know where to send it to. Regards Paul
