User Clicks A Single Button And The Program Displays Each Network Adapter Description?
Aug 15, 2011In my application, the user clicks a single button and the program displays each network adapter description into a message box and then gets all the ip info for the workstation and places it into a text file and opens that text for reading. What I would really like for it to do would be to display all the network adapters into a single messagebox instead of messagebox for every adapter like it is currently doing. Here is the code I have on that button. Let me know if anyone needs more info or has any questions:

Bind TCP Server To Specific Adapter?
Jan 6, 2010How can I specify which adaptor to begin listening on?
I have an application running on a PC which happens to have 2 network adaptors running on different subnets (one network for Business LAN infrastructure, one for TCP cameras)
I have a class which opens up a TCP server and listens on a specific port for connections coming in from clients on the LAN.
The problem is that my TCP server class initialises and begins listening on the adaptor which is connected to the cameras. Any connection request coming in from the Business LAN fails, it is not dealt with.
The question is, How can I specify which adaptor to begin listening on?
Code excerpt below (this is not the full class, just key methods)
Public Sub New(ByVal Name As String)
'get config

View 3 RepliesA Network-related Or Instance-specific Error Occurred While Establishing A Connection To SQL Server?
Aug 23, 2011I 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?

.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).

View 7 RepliesVS 2008 Finding A Specific Row And Specific Columns In Data Base File (Access)?
Jul 24, 2011I wonder if it is possible to find a specific row and specific columns in data base file (Access) . You see , I am using a DataGridView control to show only SOME of the columns (fields) of a table from an Access file . For example , lets say that in the DataGridView control I only show the following fields :Field1 , Field2 and Field3 .Now , when the user selects an entry in the DataGridView control , I want to insert the text from Field4 into a text box on the form .
The problem , however , is that I don't know how to get the specific row in the data base file and also I don't know how to get the text in column (field) Field4 of that row .One thing that might be important is that the index of the row in the data base file is not necessarily the same with the index of the current row in the DataGridView control . This is because in the DataGridView control the rows are order by the contents in the ID Field .ol .

Get Id Value With Table Adapter?
May 29, 2010To get an id value after a table insert into an Access database you do a SELECT @@IDENTITY. I would like to know if this will work if your INSERT query is a table adapter query? I created an INSERT query for a table in the dataset designer which is working. My concern is that if I make another query with SELECT @@IDENTITY it won't work because table adapters make a new connection each time. Can someone clear me up on this?
