File Modifiers Username Across Network Connection Impossible?
Apr 18, 2005
I'm running into this problem when it comes to determining a network logged on username and i hope someone can help me out or atleast point me in the right direction.Situation:1 Windows 2003 server that is serving files through Active directory. No Dfs installed, just plain files sharing.1 or multiple clients that access the files, make modifications and creates or deletes files. For arguments sake let's say that the clients are Windows XP computer and the users are logged on to the local domain (AD).Currently available:When the client alters, creates or deletes a file i have a (VB.Net Windows Service) script that tells me that this is being done and stores a record in a database for this action being performed.Desire:I wan't to know the client's ip-address, computername or logged on username so that i can store this to. I have tried about 20 different scripts but all check the username on the server side and not the client. So now i either get back "SYSTEM" or "NTAUTHORITYSYSTEM" instead of the user's AD name.Below is the code i use to monitor the directory and or file changes.The "writeDBLog" is where i want to pass the username to write to the database.

I've been looking at accessing shared folders, read and write, via the network without being prompted by the OS for the username and password.
On this forum, and googling, I can find many things about accessing network shares, but none using code which also passes the username and password required.
What I'm basically looking for is to not have to map a drive on the users computer. Then using code, write or read files from a network share and at the same time pass the username / password required for that network share.

I need to map a network drive from within a .NET application. I'm going to need to use an AD Username and Password to authenticate. Usually I just use a batch file with the net use command. How do I do this from within C# or VB.NET code?

The code can be accesses through: WatchFolder.zip..I would like to log the domain/username of the users when they are logging in from the network i.e. filesharing..I am currently using Environment.UserName and Environment.DomainName but this is not able to log if the files are access via filesharing..The Environment.UserName and Environment.DomainName are only useful if the user have logged in the machine (explorer/rdesktop)

I'd like to write a VB script that maps a network drive, but I don't really know where to start. I'd like to script to ask for a username and password, then map the drive.should I write it VB or as a CMD batch file? NET USE Z: \serverfolder\%user% /USER:%USER%@domain /password:%pass%am not even sure I've got that syntax write.

With the help of NetFileEnum or Openfiles.exe of system32, we can get the username who has opened the shared files. Is there any API function or any exe files in any programming language like c#, vb.net, visual c++ to find out who is the user to create, rename, or delete shared files or folders on the network?

I've been having huge problems having a VB.NET Windows Forms program run as a scheduled task under XP SP3. The program runs when I set the task up to use my non-admin network username and password, I can see the interface fine (albeit without the desired results - the program requires access to remote shares). When I set the task up with the network administrator account credentials, the task is "Running" but I do not see any interface. It doesn't error - it just kind of sits there happily in the background.

I have a logon screen that contains several textboxes where user can fill in their logon info (username, pass, server, database, connection port, etc.). I'd like to have the application memorize what they've put in after the first time successfully logon in form of a dropdown box. Let's say the 2nd time when users trying to logon, there is a drop down box of username, server, connection port, etc. available as a dropdown list item. They can select the info and simply enter the password.Is there a way to do that? If so, do you have an example or a reference source I can learn from?

I would really welcome some help with this issue. We have a php code that works and connects to the LDAP. When I try to connect using VB.NET 2010, it fails to bind with logon failure unknown username or bad password. Below is the connection information. When I talk to the folks who run the ldap server, they say I am binding sucessfully, below is the log file for the sucessful bind? If I continue and try to execute a search I don't get any results. The server is running openLDAP ver 2.3.39 on a linux server, server requires connection on port 636 for secure connection, or 389 for anonymous.

Does anyone know how to store the connection string in a file rather than hard coding it in the application. For example i have declared this connection string in the form to connect to oracle database and it works. But i assume this is not the right way to go by if one is looking for more secured environment.
strcon = "Provider=MSDASQL;" & _
"Driver={Microsoft ODBC for Oracle}; " & _
"CONNECTSTRING=(DESCRIPTION=" & _

But, the connection does exist and I have checked it by running the link in vb, in my computer and it works perfectly. What else could possibly bring back this error???

This is the work of one responder for the most part, and is not indicative of the quality of most of the posts.But you can judge that for yourself.
If you are writing a program that is used to monitor the status of your network, then this thread may not be of interest.
If you are an application programmer that uses network resources to accomplish your goal, i.e. you are using SMTP, FTP, HTTP, NNTP, NTP etc., and you think that you need to check for a connection first, then read on.Follow up to this.Before getting all geeky let's take a little detour...
Five days a week I get up, eat breakfast, check my email, forums, etc., take a shower, get dressed, and then drive to school.Many of you probably have a similar routine.What is interesting about that is not what we do, but what we dont do,because of our expectations and experience.Here is what I dont do.
I dont stick my finger in the electrical socket to see if there is electricity for the coffee maker and toaster.I dont fire up the command prompt and ping some host on the internet to see if I have connectivity.I dont check the battery, tires, water level, clutch fluid level, washer fluid level, etc.,before I drive off.
All of that is based on expectation and experience.So why would you write an application that pings the internet before it did something (SMTP, FTP, HTTP, NNTP, NTP etc)???? Is your experience or expectation that the network will be down?To illustrate and hopefully convince you that, like Oblio, it is pointless, create a new form with three buttons. In the following examples I use a WebRequest / WebResponse as my 'Something'.Here is what some think is a good approach, the classic ping-then-do, what I think you shouldn't do.[code]....What is wrong with this code is that all of the network IO is being done without a Try / Catch block.

I have a problem when trying to detect the computers network connection status.
Here is the code I have used:
Dim IsAvalible As String = My.Computer.Network.IsAvailable
If IsAvalible = True Then Label1.Text = "Connected" Else <code>
<code>If IsAvalible = False Then</code> I <code>
Label1.Text = "Disconnected"</code></code>
End If [/ICODE] End If[/ICODE]
But for some even when the network is disconnected or the computers wifi is turned on I still get the result of "Connected". I think there something wrong with the code.

I can't see anything in the method list that lets you know when a connection drops (and since it's constantly checking, it seems that could have been in there, to raise a flag when it can't find the connection anymore...no?). Is there a way to know if the network connection drops? Is there a way to reconnect it? Is it just a matter of turning EnableRaisingEvents() off and back on to re-establish the link to the network share?

I have a USB 3G dongle from Orange which is like a dialup connection, rather than a wireless connection.
Is there anyway in vb.net to control this connection? So disconnect is and recconnect it etc?The reason for this is automatically getting a new ip address without manually disconnecting in network connections.

I am currently improving an existing handheld application, this app makes live calls to our network over the wireless connection, if the wireless connection is not established I am displaying a holding screen to the user, this screen rechecks connection every three seconds.I want to put a button on this screen that closes down the application if the user does not want to wait any longer. At the moment I am using the application.exit command, however it continues to finish the first original thread (i.e. trying to process the dataset) before actually closing the application, I am looking for a way to kill the application there and then!

I may be SOL on this but I thought I would give throw it out for possible solutions.I am writing a computer access control service tcontrol my kids' computer use. Plan on open sourcing it when I have it working. It is written in VB.Net and needs to work on XP through 7.I am running into all sorts of security and desktop access issues on Windows 7.The service needs to run as admin to execute the NetSh command to disable the network. But I cannot interact with the desktop from the service so I IPC to a UI to handle other stuff, but I still cannot detect from the service if the desktop is locked. Argghh!

I am using the code below to test whether the user is connected using either a wireless or LAN connection. i.e. that the cable is plugged in, or the wireless is switch off. The code works fine for this. However, if you can spot any potential problems with this or you know of a better way I would be interested to learn more.

I am working on a project using VS2010 SQL2008 and I saw an ODD behaviour , First let me tell you that the app runs without any problem in my developing pc (Windows Xp sp3 32bit)But when I was trying the application in another pc (Windows 7 32bit)I got this exception: A network-related or instance-specific error occured while establishing a connection to SQL server.The server was not found or was not accessible.Verfiy that the instance name is correct and that SQl server is configured to allow remote connections.
Now what is weird in this exception; Is when the application reaches the DataAdpater.Fill(dataset) line I got this exception but when the app reaches the DataAdpter.Insert(....) It runs without any problem .
And what is more weird is that I noticed that the dataset that is used in the previous insert procedure can later be filled with dataAdapter.Fill(...) procedure which it was giving me an exception before .
I tried these things as a solution:
1)Checked SQlBrowser running..
2)No aliases to Sql server at all to remove...
3)remote area connection--OK
4)TCP and UDP port 1433,1434 exception in firewall
5)Unistalled my only antivirus Norton
6)Added Tcp/IP ports in Sql protocols
7)My connection String is : onnectionString="Data Source=ALISQLEXPRESS;Initial Catalog=PALMSDATABASE;Integrated Security=True"
8)Also tried using Sql Server authentication (user Id and password)
what is the difference between fill and insert? My app. runs smoothly on the original pc ,What should I do?
