I don't know what Rich said because it appears not to have been posted
to the list. My only guess is that your database is having problems
with binary data? What database are you using?

Joseph and Rich:
In the previous code I obviated the "len" initialization, but it was
initialized; and I used what Rich said. The application did not
crashed, but I got this error:
error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag
I've not found any documentation about this error.
Any help again?
Best regards,
Herbert
