C# - Find Through Which Network Device User Is Connected To Internet?
Apr 1, 2011Using the code below i will get all network interfaces wich are enabled and functional on the machine.
Private netIntrfc As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
For i As Integer = 0 To netIntrfc.Length - 1
If netIntrfc(i).OperationalStatus = OperationalStatus.Up Then
[code]....
But my problem is how to get the default one, the one(ethernet adapter) through wich user is connected to internet?I need to change some settings of default(through wich user is connected to internet) adapter. settings i change through registry so i could sample add same settings for each network interface but that could cause problems and makes no point then?
EDITED:for now i have done like code below, so if this can help someone other...
Dim u As UdpClient = New UdpClient(System.Net.Dns.GetHostName, 1)
Dim localAddr As IPAddress = CType(u.Client.LocalEndPoint, IPEndPoint).Address
Private netIntrfc As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()

Copying File From Openfile Dialog Box?
Sep 10, 2010For some reason I can copy a file from a OFD box from anywhere other than my desktop.Could it be because I'm using the shell command and the file path contains spaces?I've declared the filepath as a variable. I know in a batch file you have to enclose names with spaces in "".

View 2 RepliesFind File By Extension And Last Accessed Time And If Possible User Id
Dec 6, 2011I am brand new to VB and been advised it might be the best thing to use for my problem, so here goes. I need to be able to scan a machine for all excel and access db files and list them by name and last accessed time. I would like to be able to do this in bulk so more than 1 machine at a time but thinking it my be best to do each machine seperately.
When I have the data I need it to be exported in a list to either excel or a text file or anything really. Als if possible how would I add the machine name to the list so I know which one i have scanned. I have been searching the forums and google but think I am getting more confussed as this is a whole new world for me.
VS 2010 Allow User To Find An Image File And Put Into A Form
Dec 31, 2010Finished with my overlay program. Now I want to give users the ability to show their own images. [URL] That is an example of the program. Currently on the right I just have a drop down box with that image tied to a form. I want to have a blank form that allows people to select from files on their own computer to be displayed.

View 4 RepliesWriting To XML Log - File Locking?
Oct 15, 2009Simple question. I have a log of actions that is in XML. When some action occures, the XML log is updated. I am using:Dim xmlData as XElement = XElement.Load( "DataLog.xml" )
to load the existing data. I then create a new XElement (NewData) and use:xmlData.AddFirst( NewData )Which puts the latest item at the beginning of the log. And finally, I write it out using:xmlData.Save( "DataLog.xml" )Ok, that all works fine. But there is no testing to see if anyone has (or is) updating the file ("DataLog.xml") during the process. This may result in lost data. Is there an accepted way to implement some sort of file locking structure that can be used to prevent this potential loss?
Writing To XML With File Locking
Nov 2, 2009I have some code based on some previous posts that just won't work right.The code all runs without error.
-' strErrorLog holds a valid file name with full path
-' xmlNewError holds a valid xElement value
Using holdFile As New IO.FileStream(strErrorLog, IO.FileMode.OpenOrCreate, IO.FileAccess.ReadWrite, IO.FileShare.None)[code]When I step through the code, everything works.There is no error on the xmlError.Save call.However, the actual file is NOT updated.If I remove the "Using" commands and change the save to "xmlError. Save(strErrorLog)", then it writes just fine..It's got to be something really simple, but it's frustrating that I don't get an error message.But it does unlock the file..
IDE :: XML Documentation And Intellisense File Locking?
May 20, 2009I'm currently having issues with the following scenario:
1. I will build several DLLs with "Generate XML Documentation" set.
2. The DLL and XML files are copied onto another server (the build drop).
3. The copy will fail as the XML files are being locked by other users referencing these DLLs from their open Visual Studio projects.
Note that this also occurs on a local computer; open up two Visual Studios and use reference paths to reference the Binary folders. You'll find that the refrencing instance of Visual Studio will lock up the XML files causing the first Visual Studio to have problems compiling.
1. Is this a bug in Visual Studio 2008? Why is it holding exclusive locks on these files from the other computers? Is there a fix for this?
2. Is there a way to "package" the XML file into the DLL? I've noticed a lot of other .NET DLLs in the world that include all of their comments INSIDE of the DLL. No XML files necessary. (unless they're not .NET dll's).We're doing a lot of framework development here and it's imperative to include the XML documentation... unfortunately we've had to disable it to allow new builds to trickle through.

Forms :: "Locking" Characters When The User Edits A Treeview Node's Text
Jun 9, 2010I have an application where I'm allowing the user to edit the text of a treeview node. Is it possible to "lock" portions of the node's text to keep it from being edited?
For instance, if the text is "BK01" originally, can I keep the user from editing the "BK" prefix?
I currently validate the user's input when they are finished editing, but I'd like to keep them from entering incorrect information to begin with.

I have used 2005 and 2003 for a long time, but still pretty new to 2008.

View 3 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?
