Dynamic Connection Strings - Developed Apps For Desktops With An Access Database On One Server
Jun 1, 2012[i][b]I have always developed apps for desktops with an access database on one server for one company or sql server. I had one connection string. Now I am in a situation with multiple clients using my software on their own server. This means different connection strings can anyone suggest an efficient way to do this without changing connection strings for each server throughout the application?[/b][/i]

Sql Connection Error - Re-establish Connection To The Server
May 14, 2010This 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?

VS 2008 Connection To Sql Server Failed (server/'localhost' Not Accessible)

Import Excel Data Into SQL Server - ERROR: "ODBC --Connection To {SQL Server} Servernamesqlservername Failed"
Aug 13, 2010I 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()
[Code]...
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?
.NET Connection To SQL SERVER?
Jun 21, 2010i started programming with .NET (i have express edition) and wanted to make a connection to an SQL Server..previously i had .net 2005 - i started having the issue there - i unistalled it, n installed visual studio 2008. I have installed SQL Compact that came with the .net 2008, and besides it SQL Server 2000.When I try to make a connection to the SQL Server, if server is running I have to stop it and then choose the DB i want to use. (if its running wont let me choose any DB). Then, when i select the DB i need, Im getting this error:
"The instruction CREATE FILE fount SO error 5 (failed to retrieve text for this error.Reason:15105) while trying to open or creating the fysichal file : -path- to northwnd_log.ldf.

Access 97 And Windows Server 2008 R2 Farm Server?
Oct 26, 2010We are currently using Access 97 as our database. This resides on the remote farm server (which is a Windows 2008 R2 server). We are using a front end vb6 exe which accesses the back end data.Occasionally we are getting corruption to our database and we have to make sure everyone exits the software to allow us to repair/compact it. There are 2 physical servers, each running 2 virtual machines. When the user logs onto the farm using RDP, they go to one of these 4 virtual machines.We are getting all kinds of corruption, some where # characters have been inserted into the top of one table, some where the indexes are corrupted, and some where access needs to repair the database.
View 1 Replies.NET Closing Connection To SQL Server?
May 30, 2010I have many Listviews in my Form and Im retrieving stored procedures to populates my Listviews. Is it necassary to close the connection to SQL Server once I have finished populating my Listviews?The angle which im coming from is that every 30 seconds or so I need to re-populate my Listviews with the latest cut of data from SQL Server therefor Im probably going to slow down my application if it has to connect to SQL Server every 30 seconds to get the latest cut of data... instead of keeping the connection to the SQL Server Stored Procedure live so that I can use some sort of method to refresh the data?

.NET Connection, Server Can't Be Changed
Sep 18, 2011I've been trying to make a login system for my application. Which seems to work, but when I try to connect to the database itself, it won't work. I used this code to check the exception:
Catch myex As MySqlException
MsgBox(myex.Message)
That gives this exception:
"Acces denied for user '[my db user]'@'[My IP-Address]' (Using Password: YES)"
The code I use for the connection is:
Dim Connection As New MySqlConnection("server=[The SERVER IP]; user id=[DATABASE USER]; password=[DB USER PW]; port=3306; database=[DB NAME]; pooling=false")
Connection.Open()
MsgBox("Connected")
As you can see, I've tried to change the 'server' part, but it won't affect anything. It will just say my ip address (localhost, I assume) in the exception. Telling me that it couldn't connect to it. Which is not even what I'm wanting to do.

View 2 RepliesConnection String For Sql Server ?
Apr 19, 2012I 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.

Involve A Connection To An SQL Server
Aug 12, 2010I am wondering if it is possible to perform some SQL command on a datatable. I currently have an application which reads in an excel spread sheet using the excel COM, and stores the data in a object array. The Object array is then used to create a datatable based on user specifications. I have added a number of checked list boxes which are populated with the column names and row number. The user can select what rows and columns that want to see, and the datatable is recreated to their needs and displayed in a datagridview.
Although at the moment the program is fairly simple in design, but I plan to add a bit to it. I am now wondering if you can use an SQL statement to extract a set of data from a pre-existing datatable. Most examples I have seen involve a connection to an SQL server,

Sql Server - SQL Connection Strings
Mar 19, 2012I'm creating a program in VB.Net that heavily interacts with 2 large MSSQL databases. I do not know a ton of vb and I'm fairly new, but I would assume just having the connection strings in the code and releasing the program it would be quite easy for someone to reverse the program and get my connection info? correct me if I'm wrong. My question is I'm wondering if there is a safer way to use a connection string in my program. Would I just have to encrypt my app? Create a module or dll?
