Arduino And VB.Net 2008

For a little while now I have been trying to Interface Arduino and Microsoft Visual BASIC .NET 2008. However all my attempts Have failed. I was wonder if someone could tell me how to Interface them. I dont understand Firmata so I am using Serial, But in VB.Net it tells me that Access to COM15 (My arduino COM) is Denied. Can anyone help me? I am fairly new to both Arduino and VB.Net so if someone could take it down to Level 1, I would appreciate it.

Thanks!

Access to COM15 (My arduino COM) is Denied. Can anyone help me?

Do you have the Arduino IDE running at the time?

Don't. Microsoft's operating systems produce some of the most cryptic error messages I've seen. "Access denied" can mean any one of three very different things.

99% of the time Access Denied means the port is in use.
