I use the Query control to open *. Dbf accessed data, when the number of operations for a long time, about 90 times on the wrong, how to solve? Each operation has turned off Query. Error message: Capacility not supported. Too ; Open files, you may need to increase MAXFILEHANDLE limit in IDAPI configuration.

you is to first build a DataBase, then Query.DataBaseName settings as DataBase.DataBaseName?
I generally use DataBase control, and then DataBase control point BDE created AliseName, then Query, Table pointing DataBase, this should not occur too many open problems.
