Establishing Connection Between VB 2008 And Microsoft SQL
Nov 29, 2009I am developing an application with Visual Basic 2008 Express Edition and using the Microsoft SQL Server 2008. I have tried to connect the application to the server and database but I couldn't.I have found the following connection string:[code...]
I really do not know where to put this connection string and how to get its details such as SERVER_NAME_OR_IP_ADDR. I am also using SAVE and SEARCH buttons to save the input form to the database search using SQL queries. Do I have to use a separate function for this string or put it every time I need to connect to the database?

View 2 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?

View 3 RepliesSql - Copying A Table From One Database Into A Database On A Different Connection (ADO.NET)
Jun 17, 2011I am trying to copy a table in a database into another database on another connection in VB.NET, using OleDb. If they were on the same connection I would just use SELECT INTO, but they are not. I have two different OleDbConnection and cannot see an easy way to do this.
Right now I am attempting to just copy the database into a DataTable using an OleDbDataAdapter, and then loop through the DataTable and insert every record into the target database one at a time. This obviously takes a ton of time for the large DB I could potentially be dealing with, and I have to deal with escaping strings, null values, etc.
edit - just to make this more clear: I have two OleDbConnection objects, one is linked directly to a local .mdb file on my computer (JET). The other is linked to a database on our servers (SQLOLEDB). I am wanting to do this:
"SELECT * FROM fromDB INTO toDB"
But I can't because fromDB and toDB are on different connections, and the OleDbCommand object is only attached to one. The only way I can see how to do this is to connect to fromDB, copy it into a DataTable, connect to toDB, and copy all of the data in the DataTable row by row into toDB. I was wondering if there is an easier way to do this.

Create A Connection To A Database?
Aug 5, 2009I wrote a small application in witch I create a connection to a database. I'm new to this, so I followed the steps in MSDN help. I first created a link to the database with the "Datasource" of the Visual Studio environement. Then, in the code, I create instances of the dataset in the datasource and use a tableAdapter to register my changes in the database.
Now I want to allow the user of the application to specify the path of the DB file he wants to use. How can I do so? Do I still can use the datasource in the VS environment? I don't know where to start.
