I added a connection (ADO.NET) object by name testCon in the connection manager - I wanted to programmatically supply the connection string. So I used the "Expressions" property of the connection object and set the connectionstring to one DTS variable. The idea is to supply the connection string value to the variable - so that the connection object uses my connection string.
Then I added a "Backup Database Task" to my package with the name BkpTask. Now whenever I try to set the connection property of BkpTask to the testCon connection object, by typing testCon, it automatically gets cleared. I am not able to set the connection value.
Then after spending several hours I found that this is because I have customized the connection string in testCon. If I don't customize the connection string, I am able to enter the "testCon" value in the connection property of the BkpTask.
I need detailed instructions on how to connect to a database from a Microsoft Access 2007 database to a Microsft Office Accounting 2007 database. The accounting database is an SQL 2005 datbase. It has an instance name of "MSSMLBIZ".
When I try I get an SQL error 53. Do not have permissions or database does not exist.
Hi-I have a sql server database, and am wring web apps to access it.I've created databases different ways, and ended up with different owners (eg dbo, nt authorityetwork services...)I also have connection strings using windows authentication, and some using a user name and password.I have read that using windows authentication is the best way to go, as far as security goes, but I have noticed some connectivity issues when I upload the site to the server, and test it remotely. What is the safest 'owner' of the database, and what's the safest way to connect?Thanks Dan
I'm having problems with the code to connect to an SQL DataBase...i'm not experienced with asp.net. I used to work with VB.NET 2003 and SQL Server 2000. Recently i instaled VB.NET 2005 and SQL Server 2005, becouse i couldn't install the earlier VB and SQL (problems with install) so i install the new versions of VB and SQL 2005, but this is like new to me. The problem is that there is new features that i'm not familiarized with...I have this code, a simple code to retrieve data to the webform: ------------------------------------------------------------------------------------------ Imports System.Data.SqlClientPartial Class data-ask Inherits System.Web.UI.Page Private Sub page_load() Dim connection As SqlConnection Dim mycommand As SqlCommand Dim myDataReader As SqlDataReader Dim SQLStmt As String connection = New SqlConnection("Server=matrixWebSite1;uid=sa;pwd=1234;database=aspnet-books;trusted_connection=yes") connection.Open() SQLStmt = "SELECT * FROM books " mycommand = New SqlCommand(SQLStmt, connection) myDataReader = mycommand.ExecuteReader() While myDataReader.Read() Response.Write(myDataReader.Item("books_name") & " - " & myDataReader.Item("book_price") & " Euros<br>") End While connection.Close() End SubEnd Class -------------------------------------------------------------------------------------------What happens is that when i load, the page is blank (no errors is shown) just blank page.I don't know if the connection to database(outside the code) is right (permitions, etc...)Can anyone tell me what is the problem? Thank you....
I am completely new to this so sorry if i am doing something stupid.I have a basic code for connecting to Database but for some reason i get the next error: " System.Data.SqlClient.SqlException: An error has occurred while establishing a connection to the server.

I registered a domain on Internet. I cannot access my Datatbase on my WebSite. [on www.waist7.com] What connection string Shall I write ?
I created my Database with MSSQLmanager on INTERNET on my domain. I added a new TABLE and some data .
I do not know what I should write in "data source=?????" My database is Called "JOB" so i wrote: Dim SQ as new SQLConnection("Data Source=localhost;Initial Catalog=JOB; user=me;password=myPass;") Where did i go wrong ??? [Maybe 'localhost' should be replaced with something else. ?]
Actually I get A RUNTME ERROR SAYING: "Connection cannot be opened....maye because on default settings you cannot access Databases Remotely !"

Hi I have deployed a website on a server having Windows2000, IIS5.0 . It uses SQL Server 2000 which is on another remote server. While developing I used the visual tools in VS.net to make a connection and have used DYnamic properties of the connection object to map the connection string to the entry in to the config file. This works fine on my developement machine which has IIS and SQL Server 2000 on the same machine. The entry in the web.config for my connection string is:
value= " server=xxx.yyy.com; Trusted_Connection=yes;provider=SQLOLEDB.1;Initial Catalog=events; User id=myuser; Password=password;"
where xxx.yyy.com is the server running SQL Server2000.
I do not get any error but the conncetion doesnot happen and my datagrid doesnot get filled. The code for creating the connection is designer generated code. Any clues? -svp
All my dreams will come true with this ASP.NET langauge if I only can succesfully connect to my SQL Server 2000 database... I've tried many ways, many parameters...
Can somebody plz gimma the right code to connect a database?
My question is, are the user id and password optional when creating a database connection string? I've created an asp page without including them, but in my aspx page (which is basically supposed to do the exact same thing as the asp page), I'm receiving the following error:

I have a question about data base connections I need to know best practices on how to use them within method. I have a project that is running out of connections to the database and I’m not sure why. so here is a sample of what I’m doing in my database methods. Please point me in the right direction.
Question 1: Now then say I have a method called getBrokerID in a class called brokers, and this method returns a string value. Now then do I need to put the dim cnn as new sqlConnection, and the dim resultSet as sqldatareader above the Try statement? And add the cnn.close(), and resultSet.close in my exception statement? Or will the connection be closed at the end of the End function block without any extra code. Which is what I always thought happened but it seems not to be the case. Cause if I take out all my cnn.Close, and resultSet.close statements I start running out of connections to the connection pool even with the CommandBehavior.closeconnection. So to me it seems like the calling object is leaving that connection open. For example if I had a form that loaded broker data like this do these questions happen?
Public sub Init() Dim broker as new brokers Broker.getBrokerID() ‘Question 1a. if the cnn.close is removed does the connection cnn stay open here? Broker.doSomethingElse() ‘Question 1b. Now a new cnn is created now do I have two connections open to my pool? End sub
Public class Brokers
Public Function GetBrokerID(ByVal Broker As String) As String Try 'check to see if a ' is in the broker string If Broker.IndexOf("'") > 0 Then Broker = Broker.Insert(Broker.IndexOf("'"), "'") End If
Broker = Trim(Broker) Dim cnn As New SqlConnection(ConfigurationSettings.AppSettings("ConnectionString")) Dim sqlSelectCmd As SqlCommand = New SqlCommand("BrokerRecord", cnn) sqlSelectCmd.CommandText = "select SalespersonNumber FROM QueryMaster..ARD_SalespersonMasterfile where name = '" & Broker & "'" cnn.Open() Dim resultSet As SqlDataReader = sqlSelectCmd.ExecuteReader(CommandBehavior.CloseConnection)
Dim brokerID As String
If resultSet.HasRows = True Then resultSet.Read() brokerID = resultSet("SalespersonNumber") Else cnn.Close() resultSet.Close() Throw New Exception("BrokerID was not found for the Broker, function GetBrokerID") End If cnn.Close() resultSet.Close() Return brokerID
Catch ex As Exception Throw ex End Try End Function End class
Question 2. Returning an sqlDataReader. Now then is this a good practice to follow? Because it seems when I do this it really does leave my connection to my connection pool open, and I don’t know how to close the connection from the calling object. Because the commandbehavior.closeconnection does not seem to be closing the connection.
‘calling method for getBrokerList public sub init() dim broker as new broker dim sqlReader as SqlDataReader sqlReader = broker.getBrokerList while sqlreader.read …do something wend end sub
Public Function getBrokerList() As SqlClient.SqlDataReader Dim sql As String Dim cnn As New SqlConnection(ConfigurationSettings.AppSettings("ConnectionString")) Dim sqlSelectCmd As SqlCommand = New SqlCommand("BrokerListing", cnn)
sql = "SELECT BrokerName, BrokerID FROM tbl_CC_Broker where visibleFlag = 'T'" sqlSelectCmd.CommandText = sql
cnn.Open() Dim resultSet As SqlDataReader = sqlSelectCmd.ExecuteReader(CommandBehavior.CloseConnection) Return resultSet End Function
Question 3. would it be better to structure my broker class with a global database connection, and a global resultSet?

I am having trouble creating a connection to an MS SQL 2000 database located on a server at the hosting company I'm using, with code running from my localhost. It works when the code is executed on the server at my hosting company, but not when it is executed locally, on my computer. Also, I can't connect to the database using Enterprise Manager. The error I get is this:
SQL Server does not exist or access denied
It has worked before, so I don't understand why it doesn't anymore. It's not a firewall issue, since I have tried to connect with my firewall disabled as well.
