Anybody can help me about this case..

That's the classic error message you get if the PIC isn't switched to programming mode, which will happen if your PC doesn't supply enough voltage.
 
RCD Programmer

If i use RCD programmer it can work or not...

**broken link removed**
 
no, again that's programmer that uses your serial port to feed itself off...
It might work with the charge pump (according to the text).
But why not build a programmer with a power supply of it's own? much more reliable.
 
i have also built a JDM programmer and uses a IC prog software and serial interface.

first, it sometimes work, sometimes not. then i isolated the 5V supply and used a 7805 in the VCC pin of the pic, and programming is now always successful
 
Check that each output has a good 5v or 12+v and that it switches smoothly from 0v. I have also found that a very small cap on the data, and clock line helps.

I would've built 200 p16pro40's by the time you guys get your jdm to work :roll:

If this type of programmer don't work, why do guys still try to build them?

They do work, but they are very machine dependent - due to the simplicity (crudeness?) of the design. This is why WinPicProg doesn't support them, I don't consider them reliable enough - I get enough support emails as it is!.

The JDM programmer is really a very clever design, it's certainly unusual, and quite hard to figure out how it works - it's very confusing!.
