VS 2008 : Use The DHCP API To Retrieve A Computer's MAC Address When Given The IP Address?
Nov 27, 2009I'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

Feb 2, 2012The 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.

FTP Url In Address Bar?
Jun 22, 2010I want to run a FTP url in explorer. (Not in IE) What i want is some how when the button clicked the URL should appear in the address bar of the windows explorer.
This is because the ftp I access should be accessed in that way (By typing the url in the address bar of..lets say ..mycomputer window.)
I don't knw whether both do the same thing. But when I do I manually I could access the FTP by typing the URL in address bar in mycomputer(I think it is windows explorer) but not by typing it in the address bar of IE.

.net - Get Users IP Address When Many NIC?
Oct 24, 2010I am wanting to get the users IP address (the logged in user will be running the application under there user context on there local PC), but many PC's in our environment have multiple NIC's that have been added by VMWare Workstation, I would like to exclude these type of bridged connections and only show the "primary" NIC on the PC.The following function will get the IPv4 address, however on my test PC it is returning the bridged connection and not the IP Address of the network facing NIC.
Shared Function GetIP(ByVal computerName As String) As String
'Dim ipEntry As IPHostEntry = Dns.GetHostEntry(computerName)
'Dim tmpAddr As IPAddress() = ipEntry.AddressList
[code]....
My users have a mixture of DHCP and static addresses so cannot limit the NIC to either of these connection types. We tend to have a 172.16.x.x IP range, so is there a way to modify the above function so that it will only return a 172.16.x.x address?
