Hi, i would need help to access data from Betrieve files.

Persasive ODBC driver need a DDF file that define the "schema" for each table, my problem is that DDF file not exist.

The QBasic code that i should migrate to C#, make a substring functions and "cast" for every data type. If i can undestand the syntax, i could create the needed files.

I had used the DDF Builder of PSQLv11, but the aplication send an error "Invalid collating sequence"

Someone can upload an example with BTR and DDF files to know if it works with odbc?

Here is the code and DB: arc01.zip
