I get this error when I try to connect to my database. I used the same string provided in the database explorer "Connection String"
I do not have a password on the database.
This is a local database if that makes a difference

This error is doing my head in.I have a client running Windows XP SP3 logged into a domain. It is running MS VB 2010 Express to access the server.I have a Server called dataserver3 which from the client, I can do a start, run "\Dataserver3" and it comes up and yes I can browse to the Test.mdf file, which is a new database that was created using MS SQL Server 2008 R2 Standard edition.

View 1 RepliesThis will happen at random, and I can always just catch the error and re-establish connection to the server, but I am confused as to why. When doing lots of inserting into the sql server, I only establish one connection that is public, instead of many little connections. I had my doubts on a public sql connection, but it's been running great, and I've seen no problems until this morning. Again, this random moment I hit an error that stated, sql connection state is broken. Is it bad practice to just accept this error, and when it happens, re-establish the connection?
View 7 RepliesI have installed sql server 2005 in my machine which is installed vb.net 2008. I want my machine to distribute the database to the clients and make it as server.I don't have that much knowledge of how to overcome this issue as i am awfully naive about it.Let me start it here:I have got an application in vb.net...at first i was using ms access database 2007. then decided to switch on to the sql server since i want to distribute the database to the clients who are going to use my application.When i installed the sql server, i imported my access db files onto sql server database. i enabled tcp/ip as enable in the sql server network Configuration. i want use sql server windows authentication as my default user account of my system for the sake to simplify the issue.
Hence, i connected the sql server into the vb.net through the "add new data source".am done with that...the problem is how do i assign the connection string to the vb.net? Or how do i include a connection string in vb.net which tells every other computer that the database data source is in my computer so that every computer can automatically check it in the network.Where exactly shall i put the connection string...as far as my knowledge is concerned for access database, you can easily identify your connection string in project /properties/settings...it goes here and you put your database in any where.And what is the best connection string do i need for sql server 2005..computers are running windows xp.
This is my connection string
"Data Source=192.168.1.2,1433;Network Library=DBMSSOCN;Initial Catalog=RFX2220;User ID=sa;Password=PhhassssWord!;"
this is the error message

I am trying to do something fairly simple.. allow my user to import thier data from Excel into SQL Server, where it can be used by the application.To do this, I'm using the fairly simple code that is common everywhere I look:
strFilePath = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fdlgFileOpen.FileName + ";Extended Properties=Excel 8.0"
connExcel = New OleDbConnection(strFilePath)
connExcel.Open()

Now, on my development computer this code works perfectly. The data imports, and I can go on my merry way.
On the TEST computer, this code throws the error: "ODBC -- Connection to {SQL Server} servernamesqlservername failed." This seems very odd to me, because I'm using exactly the same SQL Server and database to interact with the application, and all the other screens in the application work perfectly. The test computer CAN connect to this SQL Server, but it keeps throwing this error whenever I try import data from Excel.I've tried everything I can think of - using the server's IP address instead of the server name, sending the SQL Server administrator data along with the request, taking out the Trusted_Connection=Yes... nothing works. What is going on here? How can this code work fine on my computer, and hiccup on another?

View 1 RepliesI am trying to make a program which outputs an Invoice Number, which consists of the first 3 letters of a person's first name and the last 3 digits of their zip code. The user enter their first and last name, then enters their city, state, and zip such as:
Name: Billy Jones
City, State, Zip: Chicago, Illinois 42349
Therefore, the invoice would look like:
Invoice: Bil349
I can get the first 3 letters of the first name fine using the substring function, but I have been stumped on how to get past all of the text to get the last 3 digits of the zip code entered.

I have two databases, one on my local work computer and other on a server. Both have been created with Microsoft SQL Server 2008. I can access both of them with connection strings that contains names of the servers and some other information. However the names contain only the ip-number of the server. And I need the full name of the server and the instance created, separated with "" character. I can see them in my SQL management studio but I need to get them from VB-code.I created SqlConnection-class but it finds only the ip-addressed name. SqlSourceDataEnumerator won't do good because it finds all unnecessary server names that I don't need. How can I find the real name of the server that is specified in the connection string?

am working on a project and am using sql server 2005 express as my database server, the problem is i can;t connect to the sql server from any machine on my local network (windows).
