i have the project about liquid volume measurement. but i don't know how to make the interface to visual basic and make database and graphics time to time...

And the Arduino question was?

please help me give me direction about this

One step at a time.

Start by getting the Arduino to do whatever it needs to do.
Make it send data to the serial port, monitoring it with the Serial Monitor.
Develop a GUI. Forget VB, and use C#.
Develop a database, Create a table to store you data.
Make the GUI application read from the serial port.
Make the GUI application write to the database.
Send me $8.00 and two ice cold Coors.

Perhaps the PLX-DAQ ( http://www.parallax.com/tabid/393/Default.aspx ) data acquisition tool would be of use to you.

I recommend also, as PaulS did, that you should get the Arduino to do exactly what you want. Then transmit the data through the serial port. Instead of making a GUI with C#, maybe you could use PLX-DAQ.

Although C# would be a great learning experience :).

Good luck.
