PIC C to PIC16F877A on PICmicro 28/40 Development board

I have the 877A on the board and then wired the simple circuit needed for the reading of a switch.

I compiled my basic program in PIC C compiler. For the programming, I do not have any ICD hardware.

I first attempted sending the hex file through Hyper Terminal to the ISP-Pro programming board which I have connected to the 28/40 with the phone cable. This was a fail.

I then tried using the ISP-Pro to Melabs universal adapter that came in my kit. I tried it once without any microcontroller attached and then with all of them attached. I connected this to the ISP Pro and then to the Melabs U2 programmer which I used with MEProg to send the hex file. when I connected the U2 to the adapter the power lights on the 28/40, the isp-pro and the U2 all went out.

Now I am back at square one trying to go directly from PIC C to the RS232 Serial port on the 28/40 board and all I get is a notification that it is connecting to ICD but no comm is selected.

Can I use MPLab or Micro Studio to make a software version of an ICD? if so how?

So frustrated after 6 hours.

When you compiled your program did you change the MPLAB default of 'program>build configuration> from 'debug' to 'release'?

If not, change this setting and recompile ( build F10) again.

I haven't tried MPLAB yet because I don't know how to use it really. Can I just take my hex file that I compiled in C? The big part of the project is to use our C compiler.
