all you need to do is add a MSCOMM component in your project. this has been explained in forum many times i think. Please search it once. you might find it.. for sure.. 
if not we are all here

thanks once again, im not yet clear because im not thorough with Visual Basic.i would like to explain my doubt once again by taking the example of the PC remote project:
even in this project there is a form. does this form takes part in the interaction between the microcontroller and PC.
in VOICE INTERACTIVE COLLEGE AUTOMATION SYSTEM PUBLISHED HERE project im intended to enquire attendance of students from phone. so what is the role of VB here.
please kindly help

As i said you need to add MSCOMM component in your project..
In Visual Basic 6.0: right click the toolbox and select "Components". Check "Microsoft Comm Control 6.0" and click "OK". Place a MSComm control (it looks like a phone) on your form (it will be invisible at runtime). You can name the control if you like, the default name is MSComm1.
For setting up MSComm1 component..
To read from serial port...
and to write to serial port..
I hope many things are clear now

For setting up MSComm1 component..
CODE:
MSComm1.CommPort = COM1 'Define COM port available on PC
MSComm1.Settings = "9600, N, 8, 1" '9600 Baudrate, No Parity, 8 bits data, 1 Stopbit.
MSComm1.InputLen = 1 'Read 1 character/byte whenever Input property is used.
MSComm1.InputMode = comInputModeBinary 'Input will retrieve data in array of bytes.
MSComm1.PortOpen = True 'Open Serial Port COM1.
MSComm1.Settings = "9600, N, 8, 1" '9600 Baudrate, No Parity, 8 bits data, 1 Stopbit.
MSComm1.InputLen = 1 'Read 1 character/byte whenever Input property is used.
MSComm1.InputMode = comInputModeBinary 'Input will retrieve data in array of bytes.
MSComm1.PortOpen = True 'Open Serial Port COM1.
To read from serial port...
CODE:
If MSComm1.InBufferCount Then
read_value = MSComm1.Input 'read_value will have whatever is sent to serial port of PC
read_value = MSComm1.Input 'read_value will have whatever is sent to serial port of PC
and to write to serial port..
CODE:
MSComm1.Output = something_to_send
I hope many things are clear now

ok
if i want to read the com port only when there is a new data received
by using interrupt
so how can we do that

for this u can make use of onComm event.
go to properties of mscomm , set RThreshold to 1.
then use code
Private Sub MSComm1_OnComm()
If (MSComm1.CommEvent = comEvReceive) Then ' if something received
Text3.Text = MSComm1.Input 'save it to text3
End If
End Sub
whenever new data is arrived , onComm event will be generated(like interrupt) and that data will be saved to text3.

hi cenadius,
visual basic itself is the programming language .
It can be installed as an integral part of Microsoft Visual studio or can be installed seperately. It does not have a freeware or shareware version so u have to buy it from microsoft.

Nope... as the name Visual Basic suggests it's closer to the Basic programming language.Nothing to do with C.
