I use visual studio 2008 and i am trying to pick out specific desgnator from a string and then display the next 5 charecters.

I get
"ArgumentOutOfRangeException was unhandled"
Startindex cannot be less than zero. Parameter name: Startindex

My code

dim networkstream as networkstream = tcpclient.getstream()
if networkstream.canwrite and networkstream.canread then
dim bytes(tcpclient.recievebuffersize) as byte
networkstream.read(bytes, 0, CInt(tcpclient.recievebuffersize))
dim returndata as string = encoding.ascii.getstring(bytes)
dim slpart as string
dim possl as integer
possl = returndata.indexof("Sl")
slpart = returndata.substring(possl, 7)
if slpart = 7 then
label1.text = slpart
else
end if

if I change it to Int(possl = returndata.indexof("sl") it stops lookinf for sl in the string coming from the network stream
