I saved a table in an ascii file with the separator character "," or ";" but I would like to protect this file and create a particular and personalized format that no one could reopen but me with my little program

of course I need the save function and to load the file and once saved

Perhaps can be a good idea!!

Then the method returns CsvText.

Code (fw): Select all Collapse

cCsvText := oBrw:ToCSV( NIL, , .f., , , "," ) 
cCsvText := ENCRYPT( cCsvText, cKey )
HB_MEMOWRIT( cFile, cCsvText )

No need to modify the classes of xbrowse.

Dear Silvio,

You should use Harbour's HB_BLOWFISHENCRYPT() if you want the max security

FWH Encrypt() and Decrypt() are quite simple, enough for many people, but an expert could break it

I Wish create a new file format but i not knor how make It

to start I can settle for the encript /decriot functions, but I wanted to save all the information I need in a single file: in reality they are matrices for creating betting systems for the lotto scheme title, rows, columns, guarantee, points and then the whole scheme that could have up to a maximum of ten columns but infinite rows depending on the numbers that are played if they are placed in doubles or triplets or quadruplets, five, sextuplets, sevenths, eights, novines and tens.
