My assignment is to write a program in C, then i have to send it to a microcontroller through usb port. I have finished a program in C, the problem is that i don't know how to send it to microcontroller through USB port.
Can some of you please help me.
It is urgent coz i have to hand it at the end of this week
thanks

unless your target board has an onboard programmer you will need a programmer such as Microchip's ICD2
http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406&dDocName =en010046&part=DV164005
If you are using Microchip's MPLAB development environment
http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406&dDocName =en019469&part=SW007002
click Programmer on the main menu, then Select Programmer, then your programmer (such as MPLAB ICD 2) - MPLAB should connect to the programmer and check the device ID, if OK you can program the device by clicking Program

thank u for your help, but i dont quite understand and i think it is not what i asked. I am sorry if i dont explain my problems well enough.
I have an assignment that i have to write a C program on PC, and i finished it. Microcontroller pic18f4550 connect to PC through USB port. Now my assignment is to send my C program to Pic18f4550, so pic18f 4550 will read it.
i dont have to program microcontroller .My PC connect with Pic 18f4550 through USB port, Pic18f4550 connect with some actuators. i have to write down a program in C on PC to ask actuators to move( new position of actuators, speed, which actuators) then send it to pic18f4550 by USB port.

Usually when using a PIC microcontroller one writes the program on the PC in C or C++, builds (complie/link) it using MPLAB to get a .hex file which is then loaded into the target using a programmer like an ICD2 (which is connected to the PC via the USB port).
what compiler did you use on the PC?
Is the intention to run the program on the pic18f4550?
Is the PIC running another program and you are just sending data to it.
What is the target board, e.g. a PICDEM 2 is ofen used for developing 8-bit pic code

my partner use MPLAP and compiler c18 to program PIc18f4550

getting the idea now!
I would normally send/receive data PC to/from a PIC target using RS232 serial communications which is easy but not as fast as USB.
When I have used USB the target board came with a driver which I called from C++, e.g. the SBC6711 which uses a TMS320C6711 DSP

My problem is same like yours...i want to send a sets of data from PC to PIC through RS232. The datasets are in text file format, so im doing the c programming to read this data. My problem now is to send each data to PIC...
Anybody know how to send data from pc to PIC?
I need the code for this prob....i'm using CCS PCW C compiler, PIC18F4550 and I have my own microcontroller board with USB 232 converter.
Nice resurrection, btw...

Compiler doesn't matter much, what matters is OS. For windows there are thousands of code samples about 'how to open a com port using winapi and not screw up with ascii/widechar file name". And there are for pic18 as well.
