[SOLVED] adc serial _C# problem

[bbgil]

Hi. guys. got some things here that you might be able to help me out. I am able to get adc going by measuring a voltage divider, able to send it to lcd and get it to the gui i created in c#. Here is the problem. as the adc is updating, so is the gui keeps getting data but its continiuous, example is voltage reading = 3.7. i am getting in gui, 373737373737. Also how to put the dot (.) between the numbers? any suggestion is welcome. I have the code here.
