Hello,
I´m having problem
with get access to my Serial Ports using C#.
I’m using Visual Studio 2005 and Vista.
I’ve
checked that the Serial Port is “COM1”, so this shouldn’t be the problem.
Error
message: “System.UnauthorizedAccessException ”.
I’ve
googled this and it seems to be some security problems, maybe with Vista.
The Code:
(using System.IO.Ports;)
public partial class Arduino : System.Web.UI.Page
{
SerialPort sp = new
SerialPort("COM1",
9600, Parity.None, 8, StopBits.One);
protected void
Page_Load(object sender, EventArgs e)
{
}
protected void
Button1_Click(object sender, EventArgs e)
{
sp.Open();
TextBox1.Text =
"" + sp.ReadByte();
sp.Close();
}
Anyone have
experience from this?
