First, I want to thank the programmer who filled this gap. I built on this code snippet and made a robot control environment that is pretty cool. I'm not very advanced with windows programming. I remember that we can add a drop-down box or a menu for choosing the specific COM port. Is there anyone here who has done that? I just want to make my program look neat and decide what COM port to connect to at run time (arduino boards choose different COM's at different computers or different times). Is there a way to make the VB program detect the ARDUINO board COM port automatically so that the user does not do anything (plug and play)?

You can accomplish this in many different ways. One way is to send a byte from the PC to Arduino containing a pin number and a value. If we divide the byte we are sending into 2 X 4-bits, we can use 4-bits for pin number 0 to 15 and the other 4 bits to also send any value from 0 to 15. This requires basic binary math which is supported by both Arduino and VB. Of course you can decide how to interpret the bit patterns you are getting from the PC Example: Suppose you want to control pin 4 to turn it on. 1) We can set the most significant 4-bits to number 4: In binary that's 0100. 2) Then we set the least significant 4-bits to 1111 to signify ON.

(use whatever system that works for you) 3) Then we send 01001111 from PC to Arduino 4) At the Arduino, our sketch will read each 4-bit into pin# + command and act accordingly. Hope this helps.
