Incorporating .NET code into a webpage
I have finally got my wake on LAN function working by using the depicus website WOL ovre internet http://www.depicus.com/wake-on-lan/woli.aspx (for those who are interested). I'm being a little paranoid and I want to make a similar webpage which does the same thing just incase the Depicus website closes down etc. On the depicus page it gives a stripped down version of .NET code for creating the magic packet. I'm not a hardcore programmer and I tried to copy the code to my website (at uni). Unfortunately I dont know how to manipulate the .NET code to make it into the usable type of code as on the depicus page. I was wondering if anyone who has the experience had any suggestions (or could help) on how to create the webpage page. I may invest time in learning html / .net from scratch but I dont know if that's over kill. Hence i need to have someone look at it before I commence. Any advice would be much appreciated.
The code is as follows:
Code:
<%@ Import Namespace = "System.Net" %>
<%@ Import Namespace = "System.Net.Sockets" %>
<%@ Import Namespace = "System.Net.Dns"%>
<%@ Import Namespace = "System.Text"%>
<script language="vb" runat="server">

Dim ch As Char
Dim len As Integer = CStr(x).Length

Else
InvertBinary += "1"
End If
Next
End Function
Private Function OrIt(ByVal x As Long, ByVal y As Long) As String
'Pad out
Dim xx As String
xx = CStr(x)
While xx.Length < 8
xx = "0" + xx

Dim yy As String
yy = CStr(y)

yy = "0" + yy
End While
For c As Integer = 0 To 7
