How to save a report FR4 into a firebird blob field?

At Fr2.5 was a function 'savetoblobfield' a it was very easy to save the report in a blob field in the firebird database.
At Fr4 I have not found a function to do this . Can anyone tell me how to implement a 'savetoblod' in Fr4 because I cannot upgrade my reports from 2,5 to 4 since I cannot save them in blob

Thanks

    At Fr4 you can use function SaveToStream.

    To save:
    var 
  f: TFileStream;
begin
  f := TFileStream.Create(fileName, fmOpenRead);
  ...
  ParamByName('YOUR_BLOB_FIELD').LoadFromStream(f);
  ExecSQL;
  ...
  f.Free;
end;

    To load:
    var 
  report_blob: TBlobField;
  report_stream: TStream;
begin
  //After querying
  ...
  //In case you use TClientDataSet
  report_blob := yourClientDataSet.FieldByName('YOUR_BLOB_FIELD') as TBlobField;

  report_stream := TStream.Create;
  report_stream := yourClientDataSet.CreateBlobStream(report_blob, bmRead);
  
  frxReport.LoadFromStream(report_stream);
  ...  
end;

    It works fine for me.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
