How to serialize fingerprinter Digital Persona in Delphi

Question

Hi, I need to save a Template.Serialize in a Blob Field, How do it?

var s : string; .... s := Templ.Serialize; --- > size less that 1632 bytes Whay?

Answer 1

This may depend on the field type in your database (not your fielddefs). Which database system are you using and what is the field type in that database table? Some database systems have several blob types which support different sizes.

What is the size (not length) of variable s before writing to the blob field? If that is less than 1632, then your problem is in serialization, not a problem writing to the blob field.

Which data access controls are you using? DBX, ADO, BDE? Post as much information as you can for a question like this.
