I really can't get my File data uploaded into the database

My table called "file" have the following structure:

id..................tinyint(3) unsigned NOT NULL auto_increment
name............varchar(64) default '0'
content......... blob
date_added..varchar(10) default '0'
size...............int(6) unsigned default NULL
folder_id.......tinyint(2) unsigned

Everything works fine until the BinaryData is about to be inserted.

This is my code for adding a file:
    ' // Lägger till ny post i slutet med följande data
    rec("id") = NULL
    rec("name") = object.Filename
    object.FileToField rec.Fields("content")' // Line simply don't work!
    rec("date_added") = date
    rec("size") = object.Size
    rec("folder_id") = file.form("folder")
end if
...returns an error msg:

Microsoft OLE DB Provider for ODBC Drivers (0x80004005)
[Microsoft][ODBC Driver Manager] Ogiltig längd på sträng eller buffert

...and in english something like "Invalid length of string or buffer"

However, all other fields get inserted properly if i comment the error line (content)

I have also tried to manually inserted the data using
rec("content") = object.BinaryData
but that don't work either.

One said this has something to do with the ODBC Driver (I use 3.51) and that it works fine in Access, but i would REALLY don't like to swith to access.

Also if you need i use those properties:

con.Open conString
rec.ActiveConnection = con
rec.Source = sql
rec.CursorType = adOpenStatic
rec.LockType = adLockOptimistic

I would REALLY appreciate all help

Thanks in advance,
