DDE Package refusing to take more than 265 CHAR

Question

Dear all,
i'm using Oracle 9i, i'm using the DDE package to get data from Excell
this is my code
     DECLARE
     CONVID PLS_INTEGER;
     AppId PLS_INTEGER;
     BUFFER VARCHAR2(5000);
     LEN NUMBER;
BEGIN
AppId := Dde.App_Begin('C:\Program Files\Microsoft Office\OFFICE11\Excel.exe C:\abc.xls' , DDE.APP_MODE_MAXIMIZED );
CONVID := DDE.INITIATE('EXCEL','C:\abc.xls');
DDE.REQUEST(CONVID,'R7C6',BUFFER,DDE.CF_TEXT,10000);
:DATA:= BUFFER;
DDE.TERMINATE(CONVID);
DDE.APP_END(APPID);
END;
the R7C6 cell contain a text of 270 character. in the buffere it is returning only 265 character.
if anyone please can tell me what cuase this.

If changing the data type to CLOB is NOT a option at the moment then you can work around using DBMS_SQL to get the LENGTH of the LONG column.
Something Like what I have below (Not tested) –
In this Function, I am passing the “Id” <Key> of the record to search and check the length of the LONG column. You can chose to pass ROWID instead.
Declare
lRtnLen Number := 0;
FUNCTION fn_len_long_str ( p_RecId In Number )
RETURN number As
mycursor Integer default DBMS_SQL.open_cursor;
l_x number;
l_long_value varchar2(32760);
l_len_of_long number;
l_blen number := 32760;
l_pos number := 0;
BEGIN
DBMS_SQL.parse( mycursor, 'select col2 from Test3 Where Col1 = :pCol2',
dbms_sql.native );
DBMS_SQL.bind_variable( mycursor, ':pCol2', pId );
DBMS_SQL.define_column_long(mycursor, 1);
l_x := DBMS_SQL.execute(mycursor);
if (dbms_sql.fetch_rows(mycursor)>0)
then
loop
DBMS_SQL.column_value_long(mycursor, 1, l_blen,
l_pos ,
l_long_value, l_len_of_long );
l_curpos := l_pos + l_len_of_long;
EXIT when l_len_of_long = 0;
end loop;
end if;
DBMS_SQL.close_cursor(mycursor);
RETURN l_curpos;
exception
when others then
END fn_len_long_str;
Begin
lRtnLen := fn_len_long_str (Pk_Of_The_Table);
Dbms_output.Put_Line ('Len Of LONG = ' || lRtnLen);
End;
