Check your wiring, but suspect your chip is damaged.

Steve

i tried with other chips but they too had the same error

yes my programmer is ok and the chip is programmed is programmed there was a problem with my programmming software i was using picgm but it gave a error but the same code with winpic could be programmed

Also, what chip/software/programmer are you using?

Do any of the lines to the programmer share pins with any other hardware plugged into the PIC, as this sometimes leads to bad reads.

Some programmers have a VPP first and/or an LVP option, which sometimes helps if it is enabled.
