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?

VS 2008 - A Network-related Or Instance-specific Error Occurred While Establishing A Connection To SQL Server

Nov 18, 2009

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.

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?

DB/Reporting :: Rdp Connection String From Database?

Sep 24, 2009

I have just written an application for myself and a few other users to use .rdp to connect to a number of servers, by clicking on the appropriate button. In the full version of the program I have two sets of connections one for when we are inside our vpn, which uses local ip addresses and DNS names; and the other which uses the external IP addresses and DNS names.This works quite well; if the user has stored credentials on their pc for the connection they connect straightaway; and if they don't the .rdp dialogue opens up with the server name/address filled in, ready for them to edit the rest of the required information.The problem for me is that this means I have to code 43 different Private Subs and then link the buttons; and I was hoping that instead of individually coding each connection, I could get the users to:Select by an option button whether the connection was internal or external

DB/Reporting :: Access-database Connection Provider (like Dao Or Ado.net) That Works On A 64 Bit Machine?

Jul 8, 2010

I've created a small DLL, an addin for Autodesk Inventor, this addin saves some information provided by the user and the program to an access(mdb)database.The whole idea behind this is that it allows users to quickly find drawings, assemblies and so on.The DLL works great on x86 systems however it has issues on x64 because I used ado.net.In a attempt to solve it I forced .net to compile it with the target x86 CPU settings.

However using this I'm unable register the dll (C:WINDOWSMicrosoft.NETFramework64v2.0.50727RegAsm.exe /codebase SavetoDatabase.dll )It says its not a proper .net dll file and therefore cannot be registered.

is there any other access-database connection provider (like dao or ado.net) that works on a 64 bit machine? Or do I need to change from mdb databases to another type (like mysql)? because sooner or later all machines its running on will be converted to x64.Or do I need to register the dll in another way?I've also tried to replace the conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0 with ACE, with no luck however

DB/Reporting :: SQL Connection/ Connecting From VB 2008 App

Aug 24, 2011

We have developed a VB 2008 app that uses SQL Server 2005 Express to store data collected by this app. This app has been designed to allow multiple connections to the one centralized database.

I have ran a few tests, and confirmed that if one computer running our app is accessing a database residing on a different computer,and the network connection between two computers has been severed, it would take approximately 3.5 minutes before I would get a connection timed out exception error from within my code.

I have deliberately set the ConnectTimeout property in the SQL connection string to be 15 seconds. But some how, SQL database engine still retries until approx. 3.5 minutes later.

My thinking is that I have a subroutine that would attempt to open a database once a minute.If the open attempt is not successful, and resulted in an exception, then I would popup a message to notify the user that the connection is not available.

Doing it this way, I have confirmed that it would take about 1.5 minutes for it to re-establish the connection, once the actual network connection has been restored.

To make the long story short, I would like to find a way to shorten the detection for a broken connection, and let the user know sooner, rather than locking up the app during the 3.5 minutes period has elapsed, and at the mercy of the SQL database engine to timeout. And why would it take 3.5 minutes to timeout the connection attempt when I had explicitly use 15 seconds in my connection string?

I would like to host all the account information in SQL due to the possiblity of hundreds of users at any given time. I also need the ability to add data to the database for users registering for the first time. The SQL server will need to be able to access the SQL Server databases remote via WAN.
