Convert Display Item to LOV

Question

We have an application made with Developper 2000. In a block
associated to a view I have 4 display items. When leaving the
result of a query (made with a previous block) they leave me too
many registrations for what takes a long time a lot to arrive to
the registrations of the end when using the scroll bar. As I can
convert one of the items (is a Display Item) in a LOV to get
directly to the selected registration?

Answer 1

I am working on a solution that consists to send an image from a BLOB column to a Java Bean through Forms via the Set_Custom_Property().
Unfortunately, I encounter a strange problem. 5 characters are bad interpreted, so the final image is totaly ugly.
I get the chunk of image like this:
FUNCTION Get_Chunk RETURN VARCHAR2
  IS
    LN$amt  NUMBER := GN$Chunk ;
    LR$raw  RAW(32000);
  BEGIN
    LN$amt := GN$Chunk ;
    -- Read the BLOB
    dbms_lob.READ(GL$Blob, LN$amt, GN$Pos, LR$raw);
    GN$Pos := GN$Pos + LN$amt;
    LN$amt := GN$Chunk;
    RETURN utl_raw.cast_to_varchar2(LR$raw) ;
  EXCEPTION
    WHEN OTHERS THEN
        RETURN NULL ;
  END Get_Chunk ;The chunks are sent to the bean that rebuild the binary image with the getBytes() methods.
For an unknown reason, 5 characters are misunterpreted:
129
141
143
144
157
