vb.net - Display sensor value from Arduino using VB .NET -


i trying create application display moisture sensor value arduino using vb .net. display sensor value in label1.text seems doesn't show correct value.

i tried display values richtextbox , display correct value. example, if reading values 1023, value displayed in richtextbox1 1023 in label1 23, or 023, or 3.

any this?

private sub serialport1_datareceived(byval sender system.object, byval e system.io.ports.serialdatareceivedeventargs) handles serialport1.datareceived     receivedtext(serialport1.readexisting()) end sub  private sub receivedtext(byval [text] string)     if me.richtextbox1.invokerequired         dim x new settextcallback(addressof receivedtext)         me.invoke(x, new object() {(text)})     else         richtextbox1.text &= [text]         label1.text = val([text])     end if end sub

why using val set text property of label1?

val returns numbers contained in string numeric value , stops reading string @ first character cannot recognize part of number.

e.g: 

dim valresult double  ' following line of code sets valresult 2457. valresult = val("2457") ' following line of code sets valresult 2457. valresult = val(" 2 45 7") ' following line of code sets valresult 24. valresult = val("24 , 57")

if receiving read value string...

label1.text = text
