Establishing Connection Between VB 2008 And Microsoft SQL
Nov 29, 2009
I 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?

1.Establishing a connection to a database(preferably one that is inherit within the project and can travel with it)
2. Setting the correct references to the database ( I tried connecting via JET with windows 7 and I get an error that I cannot use JET)
3. Query the database (Access) with SQL, and return those results to a recordset.
4. Loop through the recordset.
5. close the database connection
6. Open recordset and write data to table.

Error message receiving A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) The project is written in VB.Net 2008. Production server uses SQL 2008, Dev Server uses SQL 2000. The application has been built and published.
Prod Connection String: strCN = "server=SGMAGNCPQ03.;Initial Catalog=APO_Tax;Integrated Security=True"
Dev Connection String: strCN = "server=S04423711940995.;Initial Catalog=APO_Tax;Integrated Security=True"
The Problem: When I change the connect string from dev back to prod and try to run my app, I get the above error message. If I reboot everything works fine but if I switch the connect string from prod to dev and try to go back to prod, I'm back to the same problem.

An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

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?

I wrote a program that connected to a Microsoft Access 2000/2003 mdb file and accesses the data. It works fine, but I'm wondering if there is a way to connect to Access 2007? If I change my connection string, will my program work with access 2007 or is it more complicated then that? And if it will work, can someone provide an example of an Access 2007 database?

I am building a VB 2008 Express Edition application.I have built a database (with a single table) using SQL Server Compact 3.5 and have connected it to the project. I am able to view and edit the data using a DataGridView on a second form (tutorial made this very easy). I need to work with the data in the table within the application. how to easily load the entire table into an array or even read the table a row or cell at a time so that I can make all of the data available for manipulation within the application (the tutorials only seem to show how to display the data).

I am working on a project. Part of my project requires me to capture data, for example, email address, from certain rows/columns of a datagridview(form2.vb) and displays them in a textbox on another windows form(form1.vb) with a click of a button(Add Contact button). The problem is the datagridview on my form must be able to display databases by making a connection to Microsoft SQL Server 2005 but so far, i have not been able to do that. I have seen many codes with regards to my problem but i do not know how to implement it.
Below are my codes that i have written so far. My program's limitations are not being able to display databases from Microsoft SQL Server 2005 so i created the statement below to add columns and test my codes.
DataGridView1.Columns.Add("CustName", "CustName")
DataGridView1.Columns.Add("Email", "Email")

I'm using Visual Basic/Studio 2010 Express to run my VB program using MS Access database. I'm going to convert the Access database to a SQL Server Server Express data base so I downloaded SQL Server 2008 R2 Express onto my pc with Windows 7. The installation went fine and I actually converted my Access database to SQL server. I did not change anything in my VB program.My problem: When I run my normal program with the Access database (no changes), I now get an error when it executes the following code:
dr = cmd.ExecuteReader.
I get the error System.Data.OleDb.OleDbException was unhandled;
ErrorCode=-2147467259; Message=ODBC--connection to 'SQL ServerBilotta-pcsqlexpress' failed.

It appears the ODBC is looking for the SQL server eventhough the program is pointing to the MS Access db. How do I get it to NOT look for the SQL db? Is there a default setting for the

I'm currently doing a project that includes access 2010 My question will be what driver can I use for an access 2010 *.accdb type file? For a *.mdb it works perfectly well with
ConnString ="Driver={Microsoft Access Driver (*.mdb)};Dbq=" & Application.StartupPath & "\CITSDB.mdb;Uid=Admin;Pwd=123;"
But, when I changed the mbd to accdb:
ConnString ="Driver={Microsoft Access Driver (*.accdb)};Dbq=" & Application.StartupPath & "\CITSDB.accdb;Uid=Admin;Pwd=123;"
It resulted in errors:
ERROR[HY000][Microsoft][ODBC Microsoft Access Driver]Could not find file '(unknown)'.
ERROR[IM006][Microsoft][ODBC Driver Manager]SQLSetConnetAttr failed
ERROR[HY000][Microsoft][ODBC Microsoft Access Driver]Could not find file '(unknown)'
And then it shows me that my code for
If dsLogin.Tables(0).Rows.Count = 1 Then
IndexOutOfRangeException was unhandled
Cannot find table 0
I knew it must be the driver but I don't know what accdb driver I can use for the connstring.

I get the message "Please wait while Windows configures Microsoft Visual Studio 2008..." whenever I build the install project for my application. It configures VS for a while, then builds the project. This does not happen when I build the vb.net application itself, only the installation project in the same solution. This occurs on applications using the Leadtools library, but not others.
