Clipper NTX files are not structural and therefore not updated unless explicitly open when the table is updated. It has been so long, I think I am remembering this correctly.

three years ago i used an odbc driver made by a company called 'intersolv' to successfully update clipper indexes during writes inside a VFP program...

I do not believe intersolve exists any longer ... the product is now sold by 'Merant'

check out

for more thorough information on this subject....

i think the product listed at the above URL is identical to what i used from intersolve...
