DBAdvRichEditor not posting changes back to table

VCL TMS VCL UI Pack

Hi Bruno!

I'm not sure I get the solution... I'm loading a rtf file to a MS-SQL field of type varbinary(max)

var
  Blob, fs : TStream;
begin

    blob := FDQuery1.CreateBlobStream(FDQuery1.FieldByName('Document'), bmWrite);
    try
      blob.Seek(0, soFromBeginning);
      fs := TFileStream.Create(eFileName.Text, fmOpenRead or fmShareDenyWrite);
      try
        blob.CopyFrom(fs, fs.Size);
      finally
        fs.Free
      end;
    finally
      blob.Free
    end;
end;
In the form to edit, I set DataSource and FieldName properties in a TDBAdvRichEditorRTFIO component connected to a TDBAdvRichEditor because if I only use a TDBAdvRichEditor editor I receive Invalid stream format error.
Can you post some seudo-code to explain your solution?
