Please search it once. you might find it.. for sure.. if not we are all here http://www.8051projects.net/forum-t5021.html 2008-12-01T23:17:09-08:00 har 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 http://www.8051projects.net/forum-t5021.html 2008-12-01T23:17:09-08:00 Ajay 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..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.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 PCand to write to serial port..CODE:MSComm1.Output = something_to_sendI hope many things are clear now http://www.8051projects.net/forum-t5021.html 2008-12-01T23:17:09-08:00 Ajay .net is tough.. never used it http://www.8051projects.net/forum-t5021.html 2008-12-01T23:17:09-08:00 Ritesh okif i want to read the com port only when there is a new data receivedby using interruptso how can we do that http://www.8051projects.net/forum-t5021.html 2008-12-01T23:17:09-08:00 abbas1707 Riteshfor this u can make use of onComm event.go to properties of mscomm , set RThreshold to 1.then use code 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. http://www.8051projects.net/forum-t5021.html 2008-12-01T23:17:09-08:00 Ritesh THANKSANY NEW IDEA TO SAME BUT FOR DOT NET 2005 http://www.8051projects.net/forum-t5021.html 2008-12-01T23:17:09-08:00 pdi33 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. http://www.8051projects.net/forum-t5021.html 2008-12-01T23:17:09-08:00 cenadius can i know where to download the visual basic?what is the programming language use in visual basic? http://www.8051projects.net/forum-t5021.html 2008-12-01T23:17:09-08:00 pdi33 check this link for any ideas about finding it otherwise .http://www.8051projects.net/forum-t10202.html http://www.8051projects.net/forum-t5021.html 2008-12-01T23:17:09-08:00 sashijoseph Express editions for VB2008 are available for free.. http://www.8051projects.net/forum-t5021.html 2008-12-01T23:17:09-08:00 sashijoseph Express editions for VB2008 are available for free.. http://www.microsoft.com/express/download/At last MS is offering sth for free. http://www.8051projects.net/forum-t5021.html 2008-12-01T23:17:09-08:00 cenadius ok,thanks all,so the programming use in visual basic is c language? http://www.8051projects.net/forum-t5021.html 2008-12-01T23:17:09-08:00 sashijoseph Nope... as the name Visual Basic suggests it's closer to the Basic programming language.Nothing to do with C. http://www.8051projects.net/forum-t5021.html 2008-12-01T23:17:09-08:00 bacha i bought a buk on VB6, its bu the name Mastering Visual Basic 6 by Evangelos Petroutsosit has nothng abt MScomm...can any one plz let me kno of som gud VB buk for starters like me??i need to make a simple prog tht can read and write from the comm port...i need a gud buk tht can help me in learning VB and control for the MScomm ports too.AJAY ur tutorial is very helpful..ive learned alot from it but still i need to get extensive knowledge abt VB and its tools like MScomm http://www.8051projects.net/forum-t5021.html 2008-12-01T23:17:09-08:00 SANATH EMBEDDED Hi bacha...
