Problem With SQLConnection

Dec 18, 2007

I am working on a set of webforms that insert user data into a set of db tables. 

I set up a test of an approach using northwind and I'm having trouble getting the insert to work.   When I open the form, input the name and phone, and submit there is no error, but no record inserted into the Shippers table. 

You can see one of my approaches in the ASPX code.  I don't like having to do the select in order to do the insert -- so that's commented off. 

I'm stuck.  Thoughts about what I'm missing appreciated...

SqlCONNECTION

Public Conn As New SqlConnection("Data Source=localhost;Initial Catalog=tblUsers;UID=XXXX;pwd=XXXX")Public Conn As New SqlConnection("Data Source=XX.XXX.XX.XXX;Initial Catalog=tblUsers;UID=XXXX;pwd=XXXX")
This two commands are in my application.  I switch between the two so I can test my application.
When I put my application on the server, I use the localhost SQLCONNECTION.  The other is commented out.  However, the application continues to connect to the server with the address that is commented out.
THIS IS VERY FRUSTRATING...  HELP!!!!

SqlConnection And Performance

Nov 16, 2006

Hi there,  I'm not sure if the way I handle SqlConnection in my apps is the most performant one.So my apps use db heavily and there are loads of classes with methods like 1 using (SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["myConn"].ConnectionString))
2
3 {conn.Open();
4 // more code here
5 }
6
7
 As I use using the connection is closed and the object is disposed when leaving the code block.I know that the connection is taken from a pool and when closed it returns to the pool as though I'm not sure if it is better to have one "global" SqlConnection objectand to use that object for all classes or most of them. What about the ConfigurationManager, doesn't it slow down the performance as well when I'm accessing the ConnectionString value thousands of times?I hope someone can point out the issues.Many thanks in advance, Limbic

Sqlconnection Object

Jan 3, 2007

I need some information on sqlconnnection object.  I see it referenced in some exercises, and also displayed in the toolbox on some articles, but I'm running .net 2.0 and I have no sqlconnection in my toolbox, but more importantly, I can not seem to drop the data connection from my database/server explorer to my form to create a sqlconn object.   When I highlight the data connection (in my case it's machinenamesqlexpress.pubs.dbo)  and try to drag it - it immediately goes to a NO icon (that is a circle with a slash thru it) and I can not drop it onto my form.  I can see the database with no problems in explorer.
 I have been able to create a sqlconnection programatically:
Dim sqldatasource1 As SqlConnection = New SqlConnection()
sqldatasource1.ConnectionString = "Data Source=localhostsqlexpress;Initial Catalog=pubs;Integrated Security=True"
but how can I create it on my form??  I would appreciate any help on this matter.
 
(p.s. I am using VWD 2005 and SQLExpress)

SqlConnection Security

Jul 30, 2007

I have created an aspx page that uses the SqlConnection class to pull data from Microsoft CRM’s database, and we have placed this aspx inside CRM’s directory on the server so that it uses the same integrated security that CRM uses. This works fine on our test environment but on our live environment the Sql connection fails with the exception: "Not associated with a trusted SQL Server connection"
This is probably because our test CRM server has the database on the same machine as the web server, but the live environment has the database and the web server on separate machines.
So my question is how can I create an aspx page that takes the integrated security credentials that the user used to log into the website and uses them to access data from a database on a seperate machine?

Reusing An SQLconnection

Nov 12, 2003

Hi all,
I am accessing one database a bunch of different times all throughout my code...in various functions and different web pages. Is there a a way to create an sqlconnection that I can access all the time, instead of constanting hardcoding which database to go to? I've tried putting the info in another file and just including it where I want the database to open, but I can't use <!-- #INCLUDE --> inside of the server scripts.
Can anyone help

OleDbConnection Vs SqlConnection

Jan 22, 2004

Hi,

How much of a performance difference is there between connecting to SQL Server 2000 using OleDbConnection or using SqlConnection?

The reason I'm asking is I am taking on the task of updating an older program that uses a Access Database to use SQL Server, but it has a Database Utility class that uses OleDbConnection. I'm just debating whether it would be worthwhile to upgrade the class to use the SQL objects rather than Oledb. Program does a lot of update and insert of invidual records, and a few select statements that usually return from 1 to 2000 records up to a maximum of 50,000 records

Thanks

SqlConnection Failed Sometimes

Mar 2, 2004

I've an web app with impersonate windows authentication. IIS uses Windows authentication for this app & anonymous authentication is turned off.
This app have connectionString in Web.config where Windows autentication (SSPI) to SQL Server 2000 took place.
Now I've a piece of code:

public class SiteParameters
{
public static SqlConnection Connection
{
get
{
SqlConnection conn;
try
{
conn = new SqlConnection(ConfigurationSettings.AppSettings["connectionString"]);
if(conn.State != ConnectionState.Open)
conn.Open();
}
catch(Exception)
{
conn = null;
}
return conn;
}
}
}

No comments is needed, think...
Now, I'm going to use it in following way:

SqlConnection conn = SiteParameters.Connection;
SqlDataAdapter dta = new SqlDataAdapter();
DataSet ds = new DataSet();

SqlCommand sqlSelect = new SqlCommand("spPlanTransportSelect", conn);
sqlSelect.CommandType =CommandType.StoredProcedure;

dta.SelectCommand = sqlSelect;
dta.Fill(ds, "PlanTransport");

if(conn.State != ConnectionState.Closed)
conn.Close();
return ds;

It looks good & works good... on local machine only :( When I run app locally (doesn't matter if I call it by http://localhost/app, http://127.0.0.1/app or http://10.50.2.51/app I take proper data from database.
But when my buddy from another comp (e.g. 10.50.2.52) uses URL http://10.50.5.51/app he receives an error in line dta.Fill(ds, "PlanTransport");, but in fact conn variable is null & he receives "yellow" screen where is written that NT ANONYMOUS user is trying to log on to database...
It looks strange for me. Any tips?

SQLConnection Control

May 18, 2005

If i use the TimeTracker app from the starter kit suite and I enter my SQL connection in the web.config file it works fine,
 
If i build a simple app with just a sqladapter, sqlconnection and dataset control then enter in the page_load procedure
 
sqlDataAdater1.fill(dataset11)
datagrid1.databind()
It keeps giving my errors see below:  I created a connection with the sqlconnection control and used the same userid and password I used in the time tracker stater kit's web config file which works - I have no idea what is going on
 
*** is it better to create the sqlconnection control first then create the sqladapter or vise versa.

Opening SqlConnection - VB.NET

Sep 8, 2005

I used to use rdo in VB6 and now I'm trying to figure out how to use the SqlDataReader class in VB.NET.  I want to use an ODBC data source to specify the connection info.  I used to give the rdoConnection object a connect string that looked something like this:"DSN=[data source name];UID=[sql server user];PWD=[pwd]"I don't understand the connect string given in all the examples I've found (nor does it seem to work on my system...)
mySqlConnection = New SqlConnection("server=(local)VSdotNET;Trusted_Connection=yes;database=northwind")Does anyone have any ideas?  I'm open to explanations as well as solutions :)Thanks,jdm

SqlConnection.Parameters

Jan 19, 2006

Hello,
I've got some questions about SqlConnection.Parameters collection.
1) I tried add parameters and I don't know if following 2 codes are equivalent 
sql.Parameters.Add(new SqlParameter("@FirstName", SqlDbType.NVarChar, 10));sql.Parameters["@FirstName"].Value = firstname;-----sql.Parameters.Add("@FirstName", SqlDbType.NVarChar, 10);sql.Parameters["@FirstName"].Value = firstname;
Is some difference between this codes? Or in second case is created instance of SqlParamater automaticly?
2) I read that Add method is in asp.net 2.0 deprected. And now it uses Addwithvalue method, but when I don't write value of Parameter to the constructor, can (should) I use still Add method? In this case VS doesn't show any warning. VS shows warning only if I use value (object) in constructor.

SqlDataSource And SqlConnection

Jun 7, 2006

  In my web app, I have a number of nonvisual objects that share a SqlConnection. On one of my pages, I have a SqlDataSource ('cause it's quick and just needs to wrap a table). Is there any way to tell it, "Here, use this existing database connection?" In my quick and dirty testing, it looks like it's opening a second connection, which is wasteful.
 
Thanks,

SqlConnection Server Error

I am having a hard time finding information about this error
online.  I was hoping someone could help me with it.  I am working with
MS Visual Studio 2005.  The SQL Server version is 2000.  The error
bellow says I am trying to connect to SQL 2005.  Also, I can use MSVS
Server Explorer and SQL Server Enterprise Manager to connect to the
database.Here is my code:

Dim St As New DataSet
Dim ConnectString As String
ConnectString = "Data Source=MANDB01;Initial Catalog=MANCON_WEB;Integrated Security=True"
Connect.ConnectionString = ConnectString
Adapter.SelectCommand = New SqlClient.SqlCommand("select * from item_cat1", Connect)
Adapter.SelectCommand.Connection.Open()
Adapter.Fill(St)
Connect.Close()  
The browser is reporting this error: An error has occurred while establishing a connection to

Hi there,
I saw more than a dozen on this topic, even the problems has been solved.  But there are no postings on how to solve this issue.
In the development environment we're using SQL 2000 and in testing environment we're using SQL 2005.  I have no issue in the development environment, but unable to connect to SQL 2005 in the test environment.  Can anyone provide some suggestions?
web.config I got the following at works with SQL  2000.
 <appSettings>
<add key="MyConnection" value="Integrated Security=True;User ID=x;password=y;Initial Catalog=Fruit;Data Source=SQL2005DEV"/>
</appSettings>
After the user click on the submit button, I got the following code.
Dim conStr As String
ConStr = ConfigurationManager.AppSettings("MyConnection")
 TIA

Type SqlConnection Is Not Defined

Sep 19, 2007

 Hi all.I am using VB.Net 2002 (.Net Framework 1.0) and Sql Server 2005 Express Edition as a database. I am following a tutorial to create a connection to a database.I have written this code to import namespaces at my .aspx file.  <%@ import namespace = system.data%><%@ import namespace = system.data.sqlclient%>And, I also put this code at my Page_Load event that resides at .aspx.vb file.  Dim conn As sqlConnection conn = New sqlConnection("server=SEN-M092082D001SQLEXPRESS;database=test;Trusted_Connection=Yes") conn.open() lblItem.Text = "Connection Opened!" Those codes builds an error which is "Type sqlConnection is not defined". Can someone explain to me why this happen? I already imported the namespaces
