: : but how to connect to the database?i can show my file text into memo but i can't compare it to the database because i dont know the code
: That greatly depends on the database. If it is an SQL database, you'll need some SQL statement like this to get the value from the database:
: 'SELECT * FROM table WHERE value = "'+TextValue+'"';
: If it is an non-SQL database you need to either iterate through the record using a while-do loop or use the database search algorithms.
: If the database is a flat list of objects it might also support a search algorithm or you'll have to again write an iteration routine.
: As you can see, without knowing what kind of database it is, it is very difficult to give an answer.
