how can i get part of std_logic_vector

[Altera_Forum]

hello  

 i want to get a part of std_logic_vector  i have signal sec_vector : STD_LOGIC_VECTOR(5 DOWNTO 0) ; when i use sec_vector(3 downto 0) i get the error -> Cannot resolve slice name as type std.standard.bit_vector.  what can i do ?

Sounds like you're trying to assign a std_logic_vector to a bit vector. They are not the same thing. 

 otherwise, sounds like you're doing it correctly.  my_other_vector <= sec_vector(3 downto 0);
