Getting The Local Instance Of SQL Server Rather Than A Named Instance

Jul 29, 2010

A while ago, I wrote a web-based guestbook application that wrote it's own database.

My code was very amateurish, but, as it was my very first publication, I was very happy with it. Only about a month after I'd published it did I realize I'd made a huge mistake in the code.

I've only ever connected to a specific named instance of SQL Server, and it occurred to me that, if the SQL Server instance has a different name than the one I specified, it wouldn't work.

So, since my users will probably not know what the name of the instance of SQL Server that's running is, I thought adding a field where the user can specify it would help if they do, but what if they don't? My answer was to get the local instance, regardless of name.

I tried Data Source=.local;, Data Source=.; and other variants, but nothing worked.

Transfer Control To The New Instance In A Single Instance Application?

Jul 15, 2011

I have a single instance VB 2010 application I know how to communicate with the next instances run through the StartupNextInstance application event. The usual way of working with this is parsing command line arguments of the new instance and continue execution of the old instance. What I would like to do is replace the running instance with the new one. Is there any way to do this other than disabling the single instance property ?

.net - Server Halts Due To Large StringBuilder Instance In Memory?

Aug 2, 2010

So, I have this code that grabs a bunch of data from the database, and performs a bunch of calculations on that data. However, this is not what is causing the halt. The halt is coming in when I take all that "final" data that has been prepared, and go to write that into a text file.

Each line in the text file is being created from data that has had calculations performed on it. Each line "corresponds" to a record from the database. A user will have to perform this file export usually on about 30-40 thousand records at a time. Now, even though I am using a StringBuilder, this still halts because of the pure mass amount of records.

What I do currently in the code is create one StringBuilder, append all the data (after calcs) to it, convert it to a String, add it to a List(Of String) to be returned from the Function, and then clear the StringBuilder, and do the same for the next row, and I do this until each row has been created and appended, converted, and then inserted into the List.

Then, another class receives this List(Of String) and takes each String and eventually appends it to a file.

Does anyone have an idea of how to improve this code and make it so it doesn't halt the server every time? The reason it wasn't found out until now is because when I tested it locally I was testing it on only 1-50 records at a time.

Find SQL Server Instance Install Path Using .NET In Windows 7?

Dec 12, 2011

I have an application that allows the user to conduct database backups and restores. The users had been using Windows XP, with network security that allowed users to read the registry. For restores, the installation path to the SQL Server named instance was easily found by looking up the instance name in the registry using

restoreDir = My.Computer.Registry.GetValue("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\" & m_DatabaseInstanceName & "\Setup", "SQLPath", Nothing).ToString

They have recently upgraded to Windows 7, and locked down the registry so that users can not read values from it. Is there a way (via code) to find the path to a named instance of SQL Server, so that the app can automatically place the database files (mdb & ldb) in the correct folder?

Sql Server - Access A Shared Function From An Instance Of An Object?

Dec 28, 2010

The context of this question is that I am trying to debug performance issues (apart from the obvious ones I already know about and can find).I inherited a code base (VB.NET) for an ASP.NET app. This is an app that was developed way back in .NET 1.1 days, and was the first .NET app for a lot of the developers who worked on it.

In this code base is a class called DatabaseUtility that contains several Shared Public methods as well as non-Shared Public Functions and Subs for CRUD operations to the database (SQL Server).

It is common in my "BL" that a method creates an instance of the DatabaseUtility which essentially figures out what the connection string should be and opens a connection, as well as giving the developer a handle to the other methods contained within it.Dim utility as New DatabaseUtility()

Once I have that, I start to create parameters that I am going to pass to one of the methods in DatabaseUtility (like GetDataSet). There is a Shared method in my DatabaseUtility called CreateParameter which does essentially that. It creates a SqlParameter object so I can add it to a Parameters collection.

Now, the code base is littered with a lot of this:

utility.CreateParameter(...)However, because CreateParameter is a Shared method, I am not sure what is going on behind the scenes. I know because it is a Shared member that an instance of the DatabaseUtility is not created when I call it like this:DatabaseUtility.CreateParameter(...)

However, because I am calling it from an instance (utility), does that change the behavior at all?

VB 2008 Express - Connect To SQL Server Instance And Select The Database

Sep 5, 2009

I'm trying to connect from VB 2008 Express Edition to a database in an instance of SQL Server 2008. Both, VB and SQL Server are running on the same machine. From a VB project, when I try to define a new Data Connection I find just three Data sources available: [Code] I selected the last one but when I browse for the mdf file I cannot select it because it tells me that the file is in USE. I have stopped all the services but still I'm not able to link the database file.

Two questions: 1. Is there a way to connect to the SQL Server Instance and from there to select the desired database? 2. How to connect using the Database file.

A Network-related Or Instance-specific Error Occurred While Establishing A Connection To SQL Server?

Aug 23, 2011

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?

Named Pipes Or TCP For Client/server Communication?

The client/server communication will only take place in the same network.I can use TCP, but then I have to configure separate IP ports for every server instance. I can however simply use named pipes so I don't have to think about port numbers and simply use the name of the server instance.There will not be very frequent and/or large data client/server communication. It's some sort of a ERP application that will only communicate once per 30 seconds on average.
