How To Install Windows Application(C#) With SQLExpress In A System Which Is Having SQLExpress Already?
Jan 19, 2007
Hi All,
I have created an installation application which will install the application with SQL Express and .NET Framework 2.0.
If i install this application in a Fresh system(i.e which is not having SQL Express), it is installing the application with new database instance successfully.
But if i try to install the same in a system which is already having SQL Express, throwing "Object reference exception" because it is not able to create the new database instance.
The SQL ERRORLOG shows: Error is 3414, Severity 21, State 2 and says: "An error occurred during recovery, preventing the database 'model' (database ID 3) from restarting." Just prior to this, I get a warning: "did not see LP_CKPT_END".
Any thoughts why this might be and how I can fix this?
I have developed a stand alone application that get data from excel and dumps it in local database (sql server database primary data file) in visual studio .net 2005. I had no issues while developing the application. When i am trying to install this application in the standalone system with .net framework 2.0 and no backend database it giving the following error
I'm writing a Windows application (Visual Studio 2005, c#) utilizing a local SQLExpress database. It consists of about 10 tables and I've created about 15 Stored Procedures to address various functions... I can run the update Stored Procedures interactively within the designer and the data tables update as designed. However, if I run the update Stored Procedures from within my windows application is where they fail. I get no error messages, if I return a rowcount variable from the Stored Procedure it tells me that one row was updated (SELECT @RtnVal == @@rowcount)... but when I open the subject table in the designer, there is no new data.
My update queries address both insert and update functions, so if it is new row of data, it performs the insert action, otherwise it updates an existing row.
I can query the data using my stored procedures to load default values into my windows form, I can search and find client records to display in the form... I just can't update records. I'm of the opinion that it is a rights issue, but I can't find any resources that address user access accounts with SQLExpress and windows apps. The current connection string for my local database is set for Integrated Security = true; User Instance = true
I've tried two approaches... one utilizes my stored procedure....
Both fail... which points to the only common point in both approaches, the connection string and user rights... but I can't find any place to address user accounts or configurations for windows apps.
Because of numerous problems trying to get sqlexpress working, I uninstalled it with the intention of reinstalling (via Add or Remove Programs). However, now when I try to reinstall it, I get a message that the I am not making a changes so it won't let me install it.
I do have sql server 2005 developer's edition installed; is that the reason? and does that mean I cannot have both installed on the same machine?
I am a novice at working w/SQL and am trying to learn on my own... I download SQLExpress and installed it. However, I received a warning message that Internet Information Systems was not installed or enabled. I checked cpanel and it was not there. Figured out that I needed to check the windows components and attempted to enable it. I was asked for my XP Pro discs (which I can't find of course) in order to load admxprox.dll. How can I get a copy of that file so I can move forward???
I have the latest SQLEXPR and the Management Studio.
Management installed no problem.
I cannot install SQLEXPR due to beta versions of Visual Studio, etc. However this machine has been rebuilt with disk format and clean install of Windows XP Pro. No beta's of any kind on the machine.
Have latest version of Net 2, installed without error.
I installed SQLExpress with out error on other machines.
This morning I booted to a message "Unable to load SQLBOOT.DLL (hresult 0x8007007e). Uninstall and re-run setup." When I did the uninstall, I got a couple of error warnings re sqlboot.dll.
When trying to re-install, the install hangs up at MSXML6 with the message "Unable to find MSXM16.msi install package." I've looked at the files in the install directory and the .msi package is there. I've tried it twice with the same results.
I have XP with SP2. Install SQLExpress because I need test my system work in this plataform. The system used database in SQL Server. And try test uses SQLExpress.
The system work in my computer, I have not problem... but when the other client try to access to my computer...not the system. They cannot see me. I made ping to my computer this responsed, but in the other computer is not responed. The first instance had access, but when try access with the System the comunication lost. And now nobody can see my computer but i can see every one.
Check the access in secpol.msc in Local Policies | Access this computer form the network. And I have the group everyone, administrators.
Hello, as a ISV we develop a software product called Ultimo (www.ultimo.net). I do have a license question: is it allowed for our customers to run our webbased application on IIS and use sql server express as a database. The employees from the customer will use the application (intranet). For a small number of users sql express may do the job. Untill now we always advice sqlserver with processor license.
I'm still doing some research but I thought I'd slap a quick post up here anyway. I'm trying to create a small 'setup and deployment' project in studio 2005 that includes a prerequisite (sqlexpress). The one thing I've noticed is that there is not an option to install this silently by providing the executable with the appropriate switches. I could easily write my own small utility to do the work or I could use a third-party component like NSIS, however, I'm quite simply amazed that this feature was left out of studio 2005. It's quite possible I'm missing something...any feedback is appreciated 100 times over!
Can the template.ini be setup to upgrade a previous version of MSDE if it exists or just install it if it does not?
I currently have ADDLOCAL=SQL_Engine and UPGRADE=SQL_Engine INSTANCENAME=MSSQLSERVER in the file but that does not seem to do it if the server does not exist.
Am I going to have to create two seperate ini files and tweak my install program to select the specific one or am I missing a simple step?
I have to deal with a private network of laptops which are all equiped with preinstalled "Windows XP home"
I've installed SQLExpress on one of these, but I cannot connect on it from the rest of the laptops. (I've successfuly done this with "Windows XP profesional" though, and local connections work fine as well).
I've already setup the SQLExpress to accept conections throuigh TCP/IP but I can not think of something else. (Security comes to mind, but I do not know how to resolve it on "Windows XP Home").
Hi All,I've been struggling with this for hours...Could someone please advise me on how to convert my current File based SQL Server Express website to a Server based SQL Express one.Particularly interested in what I need to do in the SQL Express management tool, changes I need to make the projecvt itself and changes needed to get IIS to understand things have been changed.Thanks,Martin.
I am trying to install MSDE 2.8 on this OS. When I try to install, I receive the following error: Fatal error setup This setup does not support installing on this operating system
I have an 05 VB.NET windows application that will be used as a smart client for our folks in the field. The windows application includes 05 SQL Server Express. I have included in the Data Sources of my project and attached file going through the wizard Microsoft SQL Server Database File (SqlClient) ='s (myfile.mdf) and then selected all tables, views, stored procedures, and functions... the corresponding myfileDataSet.xsd with the myfile.mdf are now located in the root of the project. I now recompile the project without error and go to the properties section Publish tab... select the Application Files button and myfile.mdf Publish Status is set to Include and the Download Group set to Requried. With this in place I right click on the myfile.mdf from the Soultion Explorer and under the properties section have set the build action to compile and use the copy always setting for the Copy to Output Directory.
After the publish is completed on the client machine... install for WIndows Installer 3.1, SQL Server Express, and the Windows Application contains no data but everything else works fine.
My problem is that I need to attach the myfile.mdf to the new SQL Server Express instance on the client machine during the installation process so that when the application fires it will be pointed to the above location on the client.
Anyone have any ideas... scripts... includes for an ApplicationEvents.vb, source code on how to do this correctly?
Hi I'm pretty new to all of this. I downloded a starter kit and am a bit confised as to SQLExpress. I have SQL Server already installed and just wondering what the option are.

I don't want to mess with my current setup so just want to get some sugestions first. Anyway hope this makes sense. Thanks GP
I have just created a website with membership just using the standard SqlExpress auto generated file Everything works fine until I upload it to webspace :( I get the following Error An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) I don't have SQL Server 2005 :(

I am new to this forum . I am running through few problems for sqlserver account settings .
I) My registery key entry for MSSQLserver just has a client folder . 2) My sql server configuration manager just has sqlserver 2005 services , native client configuration and 2005 network configuration.
I can't see any server name or databases under it.
3)I normally work on EMS lite so I can see my ./SQLEXPRESS as server and databases under it and i can create logins etc ..I assigned db_owner role to one of my recent created database. but when I try to connect it says :
The user is not associated with sqlserver connection.
5) i have sqlserver express service running, vss and sql server browser running.
I googled and searched for the solution and it says the authentication mode should be turned to mix mode form win authentication.
But from where. Have i missed some installation .I am able to connect to my other database from EMS.
I am trying to write an application for a MSSQL database, using SQL Express,and Visual Studio (Express edition)I tried to connect to an existing database (named testing) but to no avail.Visual Studio claims the database does not exist.Any ideas?TIA--Q: What is the difference between a mathematician and a philosopher?A: The mathematician only needs paper, pencil, and a trash bin for hiswork - the philosopher can do without the trash bin...
Installation of SP2 in step "Feature Selection" shows SQLEXPRESS unchecked and can''t be edited/checked. I tried it many times on different servers with different OSes, etc
Does it mean that SP2 for Expres Edition should be downloaded and applieŠ² separately?
Hello,I am just getting reaquainted with programming and all. I work in GIS mapping and am having diffilculty using a ASP.net internet Map site and adding records to a needed database.I would like to be able to add records to a linked SQLExpress table when the user clicks on a map location. I adapted the following code snippet from an example that does what I would like only using an .mdb file.CODE: // create connection to database var connection; connection = Server.CreateObject("ADODB.Connection"); connection.Open("Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=OutdoorsExp;Data Source=NOLOGOSQLEXPRESS;"); status = "Can't access 'FishSQL' table."; // create recordset var recordset; recordset = Server.CreateObject("ADODB.Recordset"); recordset.CursorType = 1 recordset.LockType = 3; recordset.Open("dbo.FishTable", connection); status = "Can't append new record."; // append record for clicked location recordset.AddNew(); recordset.Fields("LongitudeI").Value = xco; recordset.Fields("LatitudeI").Value = yco; recordset.Update(); recordset.Close(); // release the .mdb file connection.Close();However, this does not add anything to the SQLEx table. What am I missing? I am thinking that it might have something to with the primary key.I had a table with way more columns then just lat/longs (as above) but only coded it to add data to the latitude and longitude fields. Nothing got added of course. Would have to add data to every field that doesnt allow nulls.How do I generate a random, unique ID for a primary key on the fly and for example add it to the appropriate column.Thanks you in adavnce for any insights.
To be as brief as possible:I had Visual Studio 2005 installed with SQLExpress 2005. worked reallll good :) I needed to convert an excell spreadsheet to SQL, so I migrated it to Access. Then the upsizing wizard would not/could not create an sql table with the data. Just would not take the data when the table was created. Argh.FINALLY figured out that the SQLexpress 2005 doesn't come with import/export.So I uninstalled the sqlexpress and installed SQL 2000 - Developer. Veeola, able to convert and created the table I needed.Now Visual Studio 2005 won't let me touch the sql file, says it requires sql server express 2005.My ISP does not support SQL 2005 yet. Is there anyway to get Visual Studio 2005 to work with SQL 2000 (only?)If I install SQLExpress over again, will it create problems when I go to publish my website, and more importantly right now, will anything bad happen when I reinstall sql express, or do I need to uninstall SQL 2000 first? Thanks...
hi:I set up a DSN via Adim tools, then I specify the connection string as "DSN=UserAppSample;Trusted_Connection=True".When I run my aspx page, it says: ERROR [42000] [Microsoft][ODBC SQL Server Driver][SQL Server]Cannot open database "UserAppSample" requested by the login. The login failed. It asks for login, but I use windows authentication. So what is wrong with this? :(
** For those 20 users (or fewer) who've read http://forums.asp.net/thread/1692306.aspx, I'm sorry that I ask the same question.Like I said above, what is the limitation of SQLEXPRESS, in terms of performance and scability?I'm creating a new webboard application that will replace the old one. I intend it to handle 200 concurrent users + 70000 records (9 years of data)The current system use Microsoft Access, which is reaching it's limit in performance and size. I took a look in the SQL Server product information page : http://www.microsoft.com/sql/prodinfo/features/compare-features.mspx.It didn't tell me what I want, like how many connections it can handle, for example.If there are limitations that might cause my application to not reach the required specification (above), I may need to switch to MySQL. I've no intention buying a licensed SQL Server 2005.Thanks in advance.PS: Why there're so few users viewing my posts? Anyone know a more active forum that may help me?
i'm using sqlexpress edition for my application and i'm wondering whether i will be able to execute the below sql statement use masteralter database <dbname> SET ENABLE_BROKER when i execute the above two lines its executing from last 30+ minutes... i'm wondering will that support in sqlexpress edition ? also, in order to use sqldependency do i have to enable broker service? thanks.
Ok it seems to me that if you use the ms recommended code to connect your apps using the app_data folder etc, that the dbs never show up in the SQLExpress manager.So I can't back them up like I can databases I connect to SQLExpress the 'old fashioned way'. Only 2 out of 6 dbs are visible in SQLExpress manager.What is the proper way to do this?Thanks,Jamey
