thankyou

What are you using for a power supply?.

suply is 18v ac input

hai i am using 18v ac supply at input & measured the dc nearly 20vdc after rectifier & i adjusted the lm317 o/p such that at zif socket the voltage is 13Vdc , i tried the ics 16f877a ,16f84a, 12f675 can olny be erase but not programmed with all delay adjustments also

Try using the manual toggle buttons on WinPicProg to switch the lines and measure the results on the actual PIC pins.

Make sure you have set up the hardware properly in the configuration, i.e set the sense of the Vdd, Data, Clk, Vpp etc. Then use the hardware check, as Nigel suggests, and toggle each line one at a time and make sure you are actually getting what you expect at the programming socket.

ofcourse i tried hardware check & i found starge that at dataoutpur at zif with pic ic is shows only 2.+ where withour ic in zif shows only 4Vdc i didn't get weather it is correct or not
