String To DataBase BLOB Field.....

Help.....

I have a string of upto 4000 characters, I then wish to store this into a
Blob field in my database.....

But I havn't had much luck..........

The field ( name : Buffer ) is set as a Memo field, but this is where I get
lost - how can I place a string into this field and then  view it ???

Any pointers are much appreciated
