Norberto,

TData inherits the skipper() method from TDatabase (it doesn't have one of it's own), so any changes would have been in TDatabase. I haven't use TWBrowse in years so I haven't noticed your problem.

Do you know what version your app was previously compiled with when it was working?

Here is some ListBox code I used before xBrowse and ADO ... and not tData .. I don't know if this code will help you ?? I have included the Skipper function as well.

Norberto,

Try using your database with fwh\samples\testbrw.prg and see if that is working.

Possibly your program is working but showing an unexpected result, i.e. there is a filter that filters out all the data.

Let us know what you find.

Regards,
James
