Hi,
I want to read weigh from electronic balance (connected through com port 1 or 2) and display it in edit box on dialog. How can I do it? Any sample code or useful link please.

Check http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnwbgen/html/msdn_serial.asp ("Serial Communications in Win32") - it comes with a full-featured sample.

Do you have information from the makers of the balance as to what gets sent or received via the serial (i.e. COM) port?

If so, you just open the COM port using CreatFile(), read the data with ReadFile(), and write with WriteFile().

I have done it like this.
I have attached a CString member variable to the CEdit control
by going to Class Wizard and selecting the member variables tab
unsigned char * rx_buffer = new unsigned char[number_of_chars+1];
Port.Read(number_of_chars+1,rx_buffer);  //read the port
buffer[0]=__toascii(rx_buffer[0]);
m_kelvin_temp = buffer[0];
for(n=1;n<8;n++)
{
    buffer[n]=__toascii(rx_buffer[n]);
    m_kelvin_temp +=buffer[n];
}
