I'm trying to use the DHCP API (using the references on pinvoke.net) to retrieve a computer's MAC address when given the IP address but I can't get the code to work. I've run all the C# code on pinvoke.net through the C#-to-VB converter but I'm stuck now.
Here's what I have so far. The value of res is always 5 (should be 0). Thing is, I can't find any documentation on what the return codes mean
vb
Private Sub GetMACDim client As String = "1.1.1.1" Dim server As String = "0.0.0.0" Dim si As New NativeMethods.DHCP_SEARCH_INFO si.SearchType = NativeMethods.DHCP_SEARCH_INFO_TYPE.DhcpClientIpAddress si.ClientIpAddress = Convert.ToUInt32(StringIPAddressToUint32(client)) Dim res As UInteger Dim oInfo As IntPtr

I was trying to make a program for a teacher that automatically determines random students that he or she can call on.I'm trying to make a program that will allow the user to add student names to a listbox. Then, when a button is pressed the program will output a random name from the list. I keep getting a lot of errors and can't seem to figure out why. Finally, I need an exit button that should close the program. I need to assign access keys, have a proper tab order, and assign default and cancel buttons for the form. Also, if you know how to implement any extra 'bells and whistles' into the program,I've tried making this program but it comes up with either a lot of errors, or it just doesn't want to debug. Was wondering if I could either get some help with the coding or the "how-to" on doing this.

The following code will list all IP addresses of each adapter on your system:
Imports System.Net
For Each IPAddress In Dns.GetHostAddresses(Dns.GetHostName)
Debug.Print(IPAddress.ToString)
Next IPAddress
How can determine which is my primary Windows adapter? ie: Running the above gives me:
fe80::c78:d30:ce6c:67cb%10
fe80::f823:5811:6404:f6d3%21
fe80::94bc:17f:5cd9:4a1%26
[code].....
My address from my router (primary address) is 192.168.1.25, or also it would be Dns.GetHostAddress(Dns.GetHostName).GetValue(4) which is the 5th element in the array If I'm obtaining a users local IP address on various machines with various amounts of network adapters, my program will break. I must know the IP of the primary Windows Ethernet/Wireless adapter in use.

I'm making a timer program, that I want to be able to store "unlimited" timer profiles, that someone can load and use. Now I've created a form that you fill with data, which then gets saved to a .xml file in a pre-defined directory. I'm now working on some sort of code that will:
1. Search the directory for .xml files
2. Find any .xml files and convert names to strings
3. Store the strings in a dropdown menu, so that when one is chosen, it loads that profile.
I think I have 1 down:
System.IO.Directory.GetFiles("C:Simple Timer")
Dim di As DirectoryInfo
di = New DirectoryInfo("C:Simple Timer")
di.GetFiles("*.xml")
