Thanks for yoru replies..My problem about ICPROG is while ı am programming 18F4550, the ICPRG gives an erro message like failed at 0000H or 0002H..With same program ı can programe the 16F877 without any problem..I am wondering that the problem is at the ICPROG or my pic,18F4550..So I want to use a different programe..
Or is there any different thing to programe 18F4550 with ICPROG?
They both support the jdm programmer and the 18f4550 according to their documentation - but I have not tried them with that chip so don't know if it will solve your problem.
As Gayan Soyza said, you really would be better using a microchip pickit2 programmer (or a clone) which are compatible.
Thanks but I need only a software programme..I should programe it on trying kit which has leds,lcd and 7segment display..So ı need only a programme,not a complete kit..
