For that I want to be able to display all network adapters, no matter which status they have. Then I want to be able to enable and disable the adapters by pushing a button.

View 2 RepliesRetrieve Primary Adapter's IP Address?
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.

View 3 RepliesGetting Address Of A Mapped Network Drive
Mar 28, 2010my first question on this board. I'm creating a media player(Like so many others). I try playing files over my network. When I pass this address "M:songssome artistsome song.mp3" to the windows media player control it actually opens "\ServerMEDIAsome artistsome song.mp3". But when my program checks if it is playing the correct song it thinks it is not, because the strings aren't equal. Is there a way in VB to get the network address of a mapped network drive? I can already see that it is a network drive but not wich address it points to.
View 2 RepliesCommunications :: Find Device On Network By Its Mac Address?
Feb 6, 2009I have a small embedded web server and to setup its network parameters I use a serial port, however this is giving me a lot of trouble due to USB to serial adapters (in some computers work in other doesn't).
However the other day I saw that Buffalo has a little program to find their NAS boxes (or network drives) when you don't know their IP address or got the wrong one so I assume they do it by looking for mac addresses.Is there any way of doing this with VB 2005 or higher? Basically I don't know the IP of the embedded server so I need to find it on a network, how do I find it?
a) I could do a general IP scan assuming it is on the same subnet than the host computer
b) if it has a different subnet... a general IP scan is not going to work, is it?

.net - Using A FileStream On A Network When The Network Drops?
Mar 26, 2012I am writing some code as part of a framework for opening a file.The file is of custom type and should not be opened by more than one instance of my application. To stop multiple file opening I use a filestream to create a lock file and then keep said filestream open. This seems to work in preventing another instance of my application from opening the file ( as it will fail in recreating the lock stream in the files open code ) but if the file is on a network share and the network drops then the original application also can not access the file any more.The code to get the lock stream is as follows:
Try
' We need to keep this stream alive to prevent other applications gaining access to the lock
mLockStream = New FileStream(mLockPath, FileMode.CreateNew, FileAccess.Write, FileShare.None)[code]....
In this I create the lock stream the first time round and then if another application tries to create it, it throws an exception and stops them from getting any further. This is kind of how it needs to work, unfortunately as I said, if this is done across a network and then the network connection is dropped for some reason then I can not delete the lock stream as I get an IOException telling me a process cannot access the file as it is open in another process ( which shouldn't be happening I don't think).
