I have made two programmer but both gave the same problem while programming pic 16F628A...
I may be using MPASM wrongly...Plz tell me how to assemble the code using it.
By the way, I start MPLAB IDE ->and open the source file-> then click on quick built option...Is anything wrong in it??

No problem man..its just the problem while programming. I used two programmers:
1) JDM programmer (serial port), and
2) p16pro programmer (parallel port)
But then also both of them fail to program the pic...so I thought there might be some error in my assembly procedure.
You can't use a JDM or parallel programmer in MPLAB. You have to run separate software (winpic,ic-prog,winpicpro etc.) that loads the hex file and programs the pic.
This situation can perhaps be averted by modding the programmer like the DL4YHF flash programmer with external supply. the design takes care of Vpp before Vdd as once pointed by Pommie. He has posted the schematic of the same in the other post perhaps, recently.
