>When I issue command REQUERY() in a form in EXE module, it causes program error - 'view definition has been changed'. When I run it in VFP environment, it's OK. Where is the problem and what does it mean 'view definition'.

Make sure that you have not included your view and DBC in your project. If you did that and then changed the table or view, the exe will be looking at the version it has in the project.
