I followed the NetworkInterface example in the the docs but its only returning my machine the others just come back as 0.0.0.0 for the IP and the MAC address’s are wrong
Now its a wireless network so that’s maybe why? if that’s the case is it possible to do something that can handle both wireless and wired?
This machine runs Win 10, the others are Win7, Win8.1… it probably need to work on Mac at some point
On windows. What do you get if you enter this command: ipconfig /all in a cmd (command) prompt
This code works fine for me.
Dim count As Integer
Dim s as String
count = System.NetworkInterfaceCount
For i As Integer = 0 To count-1
s = s + "Network Interface No: " + str(i) + EndOfLine
s = s + System.GetNetworkInterface(i).IPAddress + EndOfLine
s = s + System.GetNetworkInterface(i).MACAddress + EndOfLine
s = s + System.GetNetworkInterface(i).SubnetMask + EndOfLine + EndOfLine
Next
msgbox sBut this above example will only show connected networks with an IP address. Otherwise it is 0.0.0.0
If you need more informations of your network interface card. You can on Windows use WMI See link: https://msdn.microsoft.com/en-us/library/aa394218(v=vs.85).aspx . How to use WMI with OLEobject. You will find some example on this forum, if you search for WMI. Here are some links:

If I understand it correctly. The Xojo code does not display the ip address of: Wireless LAN adapter Wireless Network Connection 3 which is the only network interface that is connected at the moment… Hmm. I wonder if there is a virus checker in between that stops xojo for getting the info.
What happen if you switch off your firewall and virus checker on the PC. And then run your Xojo code.
How many System.NetworkInterfaceCount do you get ?
The 2 other things I was getting listed were the Ethernet and the mini port, not the other computers, I tried with the firewall and anti virus off and its just the same… I’ll see if I can find a cable and see if it work that way
To be honest the application would be used on a wired network but obviously it would be easier for me to test wireless, either that or buy enough cable to go around the house lol
if you need an alternative, maybe check NetworkInterfaceMBS class?
http://www.monkeybreadsoftware.net/class-networkinterfacembs.shtml
to get current IP of computer, I normally use local address property of socket classes.
From what I can see here, Windows does not show in the Network and Sharing Center the Mac that is attached to the same router through WiFi but is not part of the HomeGroup.
I can get computer/device names but not the IP… even C# doesn’t want to play… the big difference is these programs go un responsive so maybe something has changed
Its no biggy, it was just a “I wonder if” idea to assign render tasks to different machines, I can guess what the ip’s are at this stage I’ve got a long way to go before I need it automated

msgbox err.messageInteresting. I just found out that with RealStudio2012R2.1, the above code will not work where you have returned arrays. Seems I have to force myself using Xojo more than RealStudio
Thanks John, I’m just on sorting my network, apparently the router is blocking discovery, its a Virgin media/Netgear one so there’s hidden stuff I’ve not found yet
Thanks to the example given by @John Hansen I was able to write a program to change the IP address of an adapter to static or revert it back to DHCP. Much appreciated.
I thought I would share, I’ll add the full source to the program I wrote to download from my blog eventually.
