Hi Jim,


I believe I found your problem.


You create a Stream containing a string not a RVF file and then you use

RichView2.InsertRVFFromStream method that EXPECTS an RVF format not a

string.


I hope this help you

   StringStream := TStringStream.Create('This is the first line');

   StringStream.Position := 0;

   RichEdit1.Lines.LoadFromStream( StringStream); // load stream

contents into memorich


   Result.LoadFromStream(StringStream);


   //TBlobField(Table1.FieldByName('Data')).SaveToStream(Result);

   Result.Position := 0;

   RichView2.Clear;

   RichView2.InsertRVFFromStream(Result, 0); // inserting will merge styles;

     // RichView1 and RichView2 have the same collections of styles
