>Is it Visual FoxPro can open the clipper *.dbf with *.ntx?

There a two solutions available to do it; not native VFP;
1) Buy the codebase library and use it in VFP to update DBF's with .NTX
2) Several clipper ODBC drivers are available; you can use a view and
keep the table looking like a native VFP table and have it update clipper NTX's
