i have a problem regarding vb 6.0 hardware interfacing can anyone help me?after writing the program how we will test it whether it works? how the cable is connected to the hardware?where i have to fix the 2 ends of cable in the hardware?one end i have fixed in the hardware. but where the other end to be fixed??plzzz reply ..................

First, it's generally not a good idea to put all the periods at the end of the post. It works a lot better if you put them where they belong.
vb6.0 isn't hardware. It's software used to develop other software that might, or might, but be able to interact with some hardware. Since the application that was developed using vb6.0 runs on a PC, the only hardware it can interact with is the mouse and keyboard. It hardly seems like you need help connecting a keyboard to your computer, or a mouse.
Why do you think you need to fix the ends of the cable? Are they broken? If you are not sure, you might be better off getting a new cable.
plzzz??? This is an English language area of the forum. That word fails the spell checker in my browser. Please limit yourself, in this part of the forum to English words or commonly understood foreign phrases.
Now, what hardware are you trying to interface with? What sort of data exchange do you expect to perform with that hardware? Why have you developed a whole application if you don't have a basic understanding of there your application can even communicate with the hardware?
Arduino works as a virtual serial port, so one end of the USB cable goes in the USB port on the Arduini board, the other end goes to a USB port on the PC.
When (and only when) Arduino is plugged in to the PC's USB port you will see a new serial port on the PC, this is the port your VB program should communicate with.
For this to work you must have installed the FTDI drivers for the virtual serial port, but if you can program the Arduino board from the Arduino IDE then the drivers should already be there.
after writing the program how we will test it whether it works?
Well does it do what you expect it to? If so it works 
how the cable is connected to the hardware
Through sockets on on the computer the other on the hardware.
one end i have fixed in the hardware. but where the other end to be fixed
The other end should be connected to your computer.
Are you really asking questions as simple as this. :-/
