Send a number on USB port using Arduino

Any thoughts or helpful codes idea to program an arduino board to send a number on USB once a push button is being pressed .. so that a C++ or VB6 application can read the number from the USB port and do some task ?

The idea in a more clarified way is that I want to connect a matrix of push buttons with arduino board ( as inputs ), once a button is pressed then the arduino sends the number of the button which is numbered in the matrix as :

1 2 3 4
5 6 7 8
9 . . .

Code sample 

int inputOne = 1;  // as an example
int inputTwo = 2;

void loop()
{
If DigitalRead(inputOne, HIGH) {
 USB to send number "1"
}

If DigitalRead(inputTwo, HIGH) {
 USB to send number "2" 
}
}

So how to send a number on USB port so that a C++ or VB6 application can read it into variable or string ..

An Arduino Due can be used with the USBHost library which will allow you to do this very easily. It will mimic a keyboard or mouse.

Then you could create a button array with a PISO shift register or use the MANY breakouts on the Due to drive it.
