I have a digital weighing scale I need to connect to the PC using Serial Port. Every time I weigh an object, automatically the result/weight will display in the the textbox1 control in Visual Basic Application that I made. I need your help for the complete source code that will communicate to the weighing device and what control should I use to communicate and how?
I am using code

Private Sub Main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load<br />
        <br />
        SerialPort1.Open()<br />
        TextBox1.Text = SerialPort1.ReadExisting()<br />
        'SerialPort1.Close()<br />
        <br />
    End Sub

you need to know how the scales communicate, baud rate etc, before you can begin

yes, Bits per second=9600 Data bits=7 Parity=None Stop bits=1 Flow control=None

You want complete source code, but you don't even tell us what scales you have ? Read the manual for the scales, then write the code to work according to what the manual tells you.
