Hi,Simple question: A customer has an application using Access 2000frontend and SQL Server 2000 backend. Data connection is over ODBC.There are almost 250 concurrent users and is growing. Have theysqueezed everything out of Access? Should the move to a VB.Net frontendtaken place ages ago?CheersMike
i'm using sql server 2005 express edition as the database server for my web application. Right now, i want to deploy it and the problem is, my hosting is using sql server 2000. So, is it possible to deploy my database that has been created in sql server 2005 in the sql server 2000? I'm afraid that the connection string for sql server 2000 is different from sql server 2005. In addition, i'm using forms authentication in my web application. So, some data regarding to the forms authentication like dbo.asp_net.membership table, dbo.asp_net.roles table is in my database. Is it the table that has been created like dbo.asp_net.membership can be used in sql server 2000 since it is created by asp.net forms authentication function?
I am using asp.net 2.0, and am attempting to connect to a SQL Server 2000 database. When I run the web page either in the debugger, or by viewing it in the browser, I get the following error message:
Login failed for user 'sa'. Reason: Not associated with a trusted SQL Server connection.
I think that maybe my values for uid, and pwd are not correct? If this is the problem, then I don’t know what their values should be? Should uid always be equal to sa ??(If so why?)
Also I don’t know what the password should be. I don’t know what the name of the password as it was assigned over two years ago when I installed sql server 2000. I might need some instructions on how to find this value in SQL server.
Someone please help me if you can. Here is a snippet of the code I am using:
String sqlStmt = "INSERT INTO LogIn (UserName,PassWord) VALUES ('JohnyRocket','FastestRocket99')";
SqlConnection sqlConn = new SqlConnection("server=localhost;uid=sa;pwd=;database=MyWebSite;"); SqlCommand sqlCmd = new SqlCommand(sqlStmt, sqlConn); sqlConn.Open();
My aspx page is trying to connect to a remote server with SQL Server 2000 installed on it, the ip of the server is 172.16.3.111 and the same is the instance of SQL Server, sql server is running in SQL Server Authentication mode, user id is "test" and password is "test123", name of database is myDB,the connection string which I am providing is as follows:data source=172.16.3.111172.16.3.111;user id=test;password=test123;initial catalog=myDB;"But I am getting the following exception:SQL Server does not exist or access denied.even if I try the following connection string:"data source=172.16.3.111;user id=test;password=test123;initial catalog=myDB;"than also I get the same exception even if provide the following connection strings: "SERVER=172.16.3.111;UID=test;PWD=test123;DATABASE =myDB;" "SERVER=172.16.3.111172.16.3.111;UID=test;PWD=test123;DATABASE =myDB;" than also I get the same exceptionsCan u please tell whats the problem,is the connection string correct,the DBA has also registered me "test" as a user on the SQL server.One thing which I want to mention is that through enterprise manager I can connect and use sql server without any problems,also please note that in VS.NET when I try connecting using server explorer and test the connection than I connect successfully, than why is problem occuring in connecting throug aspx page.
Hi,My situation follows: I set up a database called TempDB and a test connection to it that works on my machine.In my database class I am trying to create a connection by doing the following: connToLookUpData.ConnectionString = "Integrated Security=SSPI;Initial Catalog=dbTest;Data Source=testServer;" but I am getting the following error: Login failed for user "Joe/ASPNET"i have windows XP OS.I based the connection string on the properties of my connection to Database 'Test'.Joe is the name of my computer. Both the application and SQL Server are now on my local machine.What am I doing wrong? any help greatly appreciated.Thanks much,Joe
I currently have the following code in my designer file <asp:SqlDataSource ID="SqlDataSource1" Runat="server" SelectCommand="select Site_name, system_id, ASP_Archive, sitetimes,HPOV_ROC, UPPER(CircuitType) as CircuitType, QwestCircuit_ID, SiteConfig,Site_Nat, PVC_VCI from tblASPCustomerWan order by Asp_Archive asc" UpdateCommand="UPDATE tblASPCustomerWan SET [Site_name] = @Site_name, [system_id] = @system_id, [ASP_Archive] = @ASP_Archive, [sitetimes] = @sitetimes, [HPOV_ROC] = @HPOV_ROC, [CircuitType] = @CircuitType, [QwestCircuit_ID] = @QwestCircuit_ID, [SiteConfig]= @SiteConfig, [Site_Nat]=@Site_Nat,[PVC_VCI]=@PVC_VCI" ConnectionString="server=localhost;Trusted_Connection=yes;uid=portal_user;pwd=Cr@zyP@55w0rd;database=CusPortal_Staging" /> I would like the change the connection so it takes it value from System.Configuration.ConfigurationManager.AppSettings("appStrConnection"), how can i do that??
i was able to succesfully configure my remote server over the internet and tried using express edition to connect to my remote server and everything when successful.
is there a way to copy that connection string used to connect to my remote server so as i wanted to create a project in vb using that connection string..
where can i find the connection string code used for my connection remotely ..
Every time I move my project from my computer to the testing server I have to change the connection string references in the aspx side and in my code behind. For the code behind I declared the SqlConnection string at the top of the code-behind page for both connection strings and comment out the one not in use. Obviously I then comment out the string not in use in the WebConfig as well. Being superlatively lazy I always look for the easiest and quickest way to do most anything - connection strings included. Having to comment out strings twice brought rise to the question of whether I can refer to the connection string in the web.config file from the code-behind page. I'm sure it can be done, and I did a good amount of hunting around, but I couldn't find any examples of code that would do that. Currently, as I said above, I have two connection strings declared at the top of my code-behind. Here's an example of one:Private sqlConn As New SqlConnection("Data Source=DATABASESERVER;Initial Catalog=DATABASE;User ID=USER;Password=PASSWORD") Then, I just use sqlConn as usual in my binding without having to "dim" it in every sub:sdaPersonnel = New SqlDataAdapter(strSqlPersonnel, sqlConn) Then there's the SqlConnections set up by the wizard on the aspx side:<asp:SqlDataSource ID="sqlDataSourcePayrollCompany" Runat="Server" ConnectionString="<%$ ConnectionStrings:DATABASECONNECTIONSTRING %>" ...> And for the connection in the web.config:<add name="DATABASECONNECTIONSTRING" connectionString="Data Source=DATABASESERVER;Initial Catalog=DATABASE;User ID=USER;Password=PASSWORD" providerName="System.Data.SqlClient" /> So, what would be the code in the code-behind page to refer to the connection string in the web.config file? Thanks!
"Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."
so I tried doing the following
SqlClientPermission pSql = new SqlClientPermission(System.Security.Permissions.PermissionState.Unrestricted);
pSql.Assert();
and then I get this error
"Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."
Hi, A quick Q for all the Sql Server 2000 beta testers out there. Does anyone know of any problems associated with using SS2000 Enterprise Manager with a SS7 backend running SP2? In particular, I'm keen to try out the Tsql debugger features, if they'll work with SS7.
Many thanks in advance, Jon Reade, Sql Server 7 DBA NEC Technologies (UK) Ltd Telford, Shropshire.
We are using an Access 2000 project to view our SQL Tables and using Access 2000 Runtime to Access the forms in the project. We have written in a locking system in VB and removed the video controls to prevent users from accessing the same records. But of course now we need to make the video controls available. This has now thrown up the problem of multiple users accessing the same records. We have tried to write code to lock records when then video controls are used but this is not working as well as we hoped. Can anyone please suggest any way of setting up locking on SQL using triggers from the Access frontend? or any other types of locking systems that could be written in the Access front end.
The box I am trying to connect to is running two instances of SQL Server. There is a SQL Server 2005 instance which is the default. There is a SQL Server 2000 instance which is named 'SQLSERVER'. I can connect to the SQL Server 2000 instance no problem:<add key="ConnectionString" value="server=MYPCSQLSERVER;database=mydatabase;user id=****;password=****" /> However, I am having trouble connecting to the Default SQL Server 2005 instance. I have tried: <add key="ConnectionString" value="server=MYPC;database=mydatabase;user id=****;password=****" /> but it doesn't work. I have tried explicitly setting SQL Server 2005 to use port 1434 (as SQL Server 2000 is running on port 1433), and then used: <add key="ConnectionString" value="server=MYPC,1434;database=mydatabase;user id=****;password=****" /> but this doesn't work either.
Am I mssing something here? Any help much appreciated Thanks...
Hi all--I'm trying to convert a function which I inherited from a SQL Server 2000 DTS package to something usable in an SSIS package in SQL Server 2005. Given the original code here: Function Main() on error resume next dim cn, i, rs, sSQL Set cn = CreateObject("ADODB.Connection") cn.Open "Provider=sqloledb;Server=<server_name>;Database=<db_name>;User ID=<sysadmin_user>;Password=<password>" set rs = CreateObject("ADODB.Recordset") set rs = DTSGlobalVariables("SQLstring").value
for i = 1 to rs.RecordCount sSQL = rs.Fields(0).value cn.Execute sSQL, , 128 'adExecuteNoRecords option for faster execution rs.MoveNext Next
Main = DTSTaskExecResult_Success
End Function
This code was originally programmed in the SQL Server ActiveX Task type in a DTS package designed to take an open-ended number of SQL statements generated by another task as input, then execute each SQL statement sequentially. Upon this code's success, move on to the next step. (Of course, there was no additional documentation with this code. :-)
Based on other postings, I attempted to push this code into a Visual Studio BI 2005 Script Task with the following change:
public Sub Main()
...
Dts.TaskResult = Dts.Results.Success
End Class
I get the following error when I attempt to compile this:
Error 30209: Option Strict On requires all variable declarations to have an 'As' clause.
I am new to Visual Basic, so I'm on a learning curve here. From what I know of this script: - The variables here violate the new Option Strict On requirement in VS 2005 to declare what type of object your variable is supposed to use.
- I need to explicitly declare each object, unless I turn off the Option Strict On (which didn't seem recommended, based on what I read).
Given this statement:
dim cn, i, rs, sSQL
I'm looking at "i" as type Integer; rs and sSQL are open-ended arrays, but can't quite figure out how to read the code here:
This code seems to create an instance of a COM component, then pass provider information and create the recordset being passed in by the previous task, but am not sure whether this syntax is correct for VS 2005 or what data type declaration to make here. Any ideas/help on how to rewrite this code would be greatly appreciated!
For nearly 6 wks I have been trying to workout with GoDaddy.com a connection string that will connect to the SQL Server 2000 from my ASP.Net web application. In my programming, I have placed the connection string in the web.config file and then call it from there within code behind using the SQLConnection object. My web.config entry has the following form: <appSettings> <add key="Conn" value="server=GoDaddyserver;integrated security=SSPI;database=databaseonGoDaddyserver;" /> </appSettings>I have also written the key supplying the UID and pwd. Nothing works and their support is of no help.Has anyone else had this difficulty either in general or with GoDaddy in particular?
Hi, i'm very new to Web Matrix. I've been following the C# end-end application tutorial exactly but i can't seem to run my application. The code given in the link below is for MS Access but I'm using MS SQL 2000, so i'm not sure of the syntax for the code provided below (string connectionString...) Please help..thank u!!
Hi there,I sincerely hope that someone out there can help. I have twoinstances of the SQL 2000 Desktop Engine running. One is on my localmachine for development and the other is on another machine on ournetwork which is the production environment. I have built an Access2003 front end application which connects to this database. Thisworks fine locally, as you would expect. I successfully installed thedatabase on the production machine and am able to connect to it viaAccess 2003 (using the Data Link Properties window) and from thirdparty database manager software (similar to Enterprise Manager). I amnot able to to connect to the database via my application.I am using the "sa" account with a strong password. This is myconnection string:strConnection = "Provider=sqloledb;DataSource=server02;UserId=sa;Password=strong;Initial Catalog=Test"The error I'm getting is:"Connection cannot be used to perform this operation. It is eitherclosed or invalid in this context."The connection string is the only thing that changes in my code when Iswitch from my local to my production database. Is there some reasonthat I can't use the "sa" account in this fashion that I'm not awareof? I'd rather not use integrated security for simplicity's sake asthis is a small, internal application. Also, I would have thoughtthat if that was the issue, I couldn't use "sa" at all, even locally.I'm going to post to the Access group as well but thought someone heremight have some advice to offer as well.Thanks,Barb
I have a child package where the ConnectionString property of a Connection Manager is set by a Parent Package Variable Configuration. I set up a script task that brings up a message box with the value of the ConnectionString property right before the dataflow task.
MessageBox.Show(Dts.Connections["CPU_*"].ConnectionString.ToString());When I run the parent package, the message box shows that the connection string is changing with every iteration, but in the dataflow it always draws the data from the same source.
The connection manager is an ADO.Net type, RetainSameConnection is set to False, and I've been researching this for days.
(Update 2/23/2015): To make this stranger, when I look at the diagnostic logs, they tell me that when the new connections are being opened they are using the new connection strings.
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.
My web project (ASP.NET 2.0 / C#) runs against sql server 2000 and uses the System.Data.SqlClient.using System.Data.SqlClient; I use System.Data.SqlClient.SqlConnection and System.Data.SqlClient.SqlCommand to make the connections to the database and do selects and updates. Is it correct to continue to use these against SQL Server 2005? I ask because I made a connection string (outside of .Net) for SqlServer 2005 using the SQL native provider and it had the following - Provider=SQLNCLI.1 and any connection strings I had made (also outside of ASP.NET) fro SQL Server all used Provider=SQLOLEDB.1. This is why I wondered if there is a different SqlClient in .Net 2.0 for SQL Server 2005? Cheers Al
Hi All, I am getting the following error if I am using the package "Transaction Option=Required" while running through Sql Job: The AcquireConnection method call to the connection manager "<connection name>" failed with error code 0xC0202009.
while I running the SSIS package on BI environment, I am getting the following error: [Connection manager "<connection name>"] Error: The SSIS Runtime has failed to enlist the OLE DB connection in a distributed transaction with error 0x8004D00A "Unable to enlist in the transaction.".
I know the alternative solution is to make the "Transaction Option=Supported", but in my case I have run the whole flow in a single transaction. I came to know that this has been fixed in the service pack1(ref. to http://support.microsoft.com/kb/914375). FYI.. some time it was running successful.
I have taken all the necessary step to run the SSIS package in a distributed transaction(like the steps for MSDTC) and also created the package flow in a sequence.
I was going through the link - http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=160340&SiteID=1 but all those didn't solve my problem.
If anyone can help me it will be great. or it is a bug in SSIS?
Hi I am trying to write the following connection string:public static SqlConnection connect() { SqlConnection sqlConn = new SqlConnection("server=9.0.3042;database=Menu;Connection Lifetime=300"); return sqlConn; } I am trying to connect to a sql database using c# code. The code above is in a seperate file.

Hey guys, sorry to bother you with something so newbish, but I am trying to connect to a remote sql server db, using vb6. I want to use ado to do so but have been having problem with some of the samples I have found online.
I will probably just test the connection out on an existing database like pubs or northwind.
Can anyone provide me a code snip please?
This forum has always been a great resource for me, thanks again guys!
Hello,I am doing the web based project for the final year of my cousein Information Technology using Asp.net and ms-sql server.But to startwith that I need to connect my web pages to the database.So Can anyone tell me how to connect my page web to the ms-sqlserver using Asp.net(Connection String)?.It will be better if someonegive me the code for the connection string along with the explainationso that I don't have problem understanding it.Any kind of help will be appreciated.Thank You.Suchen Chodankar.
Hello, I have a sql 2005 server, and I am a developer, with the database on my own machine. It alwayws works for me but after some minutes the other developer cant work in the application
He got this error
Login failed for user ''. The user is not associated with a trusted SQL Server connection. [CLIENT: 192.168.1.140]
and When I see the log event after that error, it comes with another error.
SSPI handshake failed with error code 0x8009030c while establishing a connection with integrated security; the connection has been closed. [CLIENT: 192.168.1.140]
He has IIS5 and me too.
I created a user on the domain called ASPSYS with password, then in the IIS on anonymous authentication I put that user with that password, and it works, on both machines.
I go to the profiler, and I see that when he browses a page, the database is accesed with user ASPSYS, but when I browse a page, the database is accesed with user SElevalencia.
Thats strange.
The only way that the other developer can work again on the project is to restart the whole machine. He has windows xp profession, I have windows 2000.
