Hi,

I need to read a binary file into memory and insert it into my DB (via ADO). (I have never done IO in Delphi before.) Can anyone give me a piece of code to read a binary file into memory (efficiently) and also show me the best way to insert it into the DB...

Thanks a lot,
Marius

-define a blob-field in your table
use
Dataset.edit; //or insert
TBlobField(Dataset.FieldByName('YourFieldNameHere')).LoadFromFile('YourFileNameHere');
Dataset.Post;

if you need to load into memory

var
  ms : TMemoryStream;
begin
  ms := TMemoryStream.Create;
  try
    ms.LoadFromFile('YourFileNameHere');
    //maybe some processing with the in memory content
    ms.Position := 0; //spool back
    Dataset.edit; //or insert
    TBlobField(Dataset.FieldByName('YourFieldNameHere')).LoadFromStream(ms);
    Dataset.Post;
  finally
    ms.free;
  end;
end;

hope this helps
