Help for Developing a MFC appliaction

Hi ,

I have bought a MCB23xx development kit.
We have to make a application on a windows XP machine which is going to talk to the MCB23xx board via the USB interface of the PC.

I have already configured the MCB23xx board to be a Human Interface Devices (HID) USB class type by downloading the HID example code firmware using a keil ulink2 debugger.

The code was picked up from the keil site and also i have tried and used successfully the HID client example code which is VC++ based for toggling few LED's on the board and sensing the keyboard interrupt.

My task is that i have to make a new vc++ based application which is going to have a edit box and when we type some thing in this box and when we click a send button on this GUI the typed string should go to the MCB23xx board and then appear on the LCD display present on the board.

Here are the few questions:
1)Has anyone used/worked on HID client (Host Side (PC) side) vc++ application.
2) Can i send the a string if i configure the evaluation board to be HID class type?
3)Can anyone provide me a documentation for the HID (VC++) based client application present on the keil site?
4) Also a documentation of the HID example code present on keil site would be very helpful, Has anyone used this code (Board side) for their custom application?

I will be grateful if someone answers my queries.

Thanks in advance,
Amit
