Configuration :: Accessing Databases / Able To Connect To Database Present In Same Server But Not With Database Present In Other Server?
Mar 8, 2011
I am developing web application using asp.net. Here i need to access two databases in which one is present on other server. I am able to connect to database present in same server but not with database present in other server.
I am using MS-access. I dont know the changes to be done and syntax for database connection.
my web cannot connect database SQL server 2000 after i deploy to IIS.
I can connect sql server to another computer from my query analyzer and Enterprise Manager.
but after i deploy to IIS 5.1. I cannot Login .
it always return message like this:
"A network-related or instance-specific error occured while establishing a connection to sql server. the server was not found or was not accessible. verify that instance name is correct and that sql server is configured to allow remote connections. (Provider :named pipes provider,error:40 - Could not open a connection to sql server)"
how to Deploy ? because my program work correctly in Visual Studio 2008.
but after i publish and move to wwwrooot in inetpub. my web cannot login.
my requirement is : am having a excel sheet with some values listed i want to pass each value present in any(specified) column to a text box present on a remote page (a site other than mine) as a input and capture the result displayed on the page and then store the input and reuslt side by side in db this should repeat till the end of the input values in the excel sheet.
i have database that is stored on local.user should also be able to upload the database to online server . i am able to save it on local .But it is not saving on server.It shows request time out. Is it due to server not allowing external access.
I'm trying to use a DataSet to maintain some rows for a table, and when I've finished my changes, send all changes to the database using a SqlDataAdapter.
I find if there are no rows in the table in the database then I am getting a 'Object reference not set to an instance of an object' when I try to access the table in the Dataset.
Is there a way to work with a Dataset like this ie. I start off with an empty table and I wish to add rows, to access the structure of the table rows, build rows, then add them and do the update on the SQLDataAdapter.
i have two textboxes and 1 button and label1 in my asp.net webform. when i enter Sumit in textbox1 and 23 in textbox2 then it validates the database to check whether then value entered in textbox1 is present in Name column of database and 23 is present in Age column of database....then it redirect to ~.Default2.aspx else shows error message in label.
In my website there is 1 module in which i m fetching data(Student name, Roll no.) of students from the student master table into gridview... and in that gridview there is 1 checkbox column...
I want that when i will check the checkbox of those students who are present...dat checked students and name should be get entered into another table in database where there wil be present written in front of checked students and absent written in front of unchecked students.....
I tried a lot but I am not getting it.....
From the above table(student info) i wil fetch data in gridview and will mark attendance in the gridview
In the above sample gridview in the student name column the name of the students is fetched from student info table, when I will check the checkbox and select the date and click on the button the students who are checked will be stored with a status present and those who are unchecked are stored as absent in another table
The following is the table(example) is where the data is to be stored in the same manner. It means that total two tables are there in the database.
From 1 table i fetch data of students info in gridview and in another table i wil save the attendance marked in gridview....
I have created a web application and an SQL database using Web Developer 2010 Express. I have SQL Server 2008 and SQL Server Management Studio Express. In order to deploy the database to my hosting space I need to create a .BAK file from my new database. I think I can do this from with the Management Studio, but can't figure out how to get it to connect to the database. I have used Management Studio before to retore another SQL database and the only connection I see when I open the Management Studio is the old connection to the old database. How do I connect to my new database?
I have a web application where i need to search the files present in a server folder using the text given in a textbox.I have developed the logic and its working fine.I have added the files to a ArrayList and have used to display the searched files using a datalist.I am getting all the searched files correctly.I have added a hyperlink field so that i can open the files.But when when in click the files its not opening the files rather going to parent directory.

I have created web pages using VS Web Developer that use a local Developer Edition of SQL server database on my PC with LINQ to SQL. When I deploy my website to a remote web host SQL server, I need for my web pages to be able to use the remote database instead of the local database. So, how do I get the Server Explorer to connect with a remote SQL Server database?
I am developing and app to find automatically characters stats with the 2nd edition dnd rules to be easy for my party to create characters when we play.
I am using Visual studio 2010 c sharp express and Sql 2008 express R2.I have added a database in the project to have all the data needed. When I use the release folder or the debug folder on other pcs the app doesn't run. Wherever I install SQL server (database and management) things are fine. I googled but I am not sure what to look exactly for and made a brief search here but with no results. I am trying to make sth that has almost no dependencies but well I can't avoid installing .net framework 4 everywhere...
Is there anyway to make database work without installing SQL? Is there any workaround like a dll or sth?

I am having trouble trying to access a UserControl I created and placed inside the EditTemplate of the ListView. How is it done? I've tried to access it at the ListView's ItemDataBound, ItemEditing and Databound with the following code with no luck:
I have a c# window form application (which is basically a game).And an ASP.NET Website. the window form application has a database with a table that contains the username and his cash. The asp.net database has a table that contains the username and his cash.Now I want to sync between to the two servers. Once I get point in my game, It'll also update the database of the asp.net site.
I built an ASP.NET 4.0 Web Site. It works perfectly on my development computer. However, when I deploy the web site to theProduction Server, which is a Win2003 Small Business with Sql Server 2000, the site can't connect to the database.
These are the different tests I've made:
I tried using Integrated Windows authentication and this connection string: Data Source=myServerAddress;Initial Catalog=myDataBase;Integratedsecurity=true; and the error I got was that NT Authority/Network Service couldn't open the database. So I added that account to my database users list and gave it the appropiate permissions. Nothing.I tried using Sql Server authentication, so I created a new database user with a password and changed my connection string toData Source=myServerAddress;Initial Catalog=myDataBase;User Id=myUsername;Password=myPassword;. Nothing. I still got the same NT Authority user message.I deleted the used I created in step 2 and used the same connection string, to see if this time I got an error saying something about my user, and indeed it happened. I got an exception saying that user myUsername couldn't log on. I then created the user again, ang got the NT Authority user message one more time.I created a console application that used the same connection string from steps 2 and 3, and it connected to the database witouth any problem, which made me think that my problem's got something to do with my Web.config.I tried enabling impersonation on my Web.config, and thos time I got the same error message, only referring to the user I logged in to Windows, instead of NT Authority/Network service. What else could I check? My Web.config is this in case it helps (I havn't really put anything into it other than what VS puts):
I'm currently developing a website using VS2010 Express/SQL Express 2008, and am using the applications development server to test.
I have created an access layer which effectively takes all my cachable data and creates datasets.
I've also created a system wheras for each dataset, For each dataset I also create a token cached object (a string), which is set to expire before the dataset. The theory behind this is that when my token expires and is removed from cache, it calls a routine to rebuild the dataset, and re-caches the new result, then creates a new token. Think of it as a poor mans SQL dependency.
What this allows me to do is rebuild datasets behind the scenes with little interruption/delay throughout the day. It all works great - for instance when a user updates a table containing 100,000+ records on the site, the dataset rebuilds at hourly intervals reworking and consolidating the data in the background before representing it in a smaller cachable form.
What I would like to know is this. If I was to replace the database during the usable day (only updating the tables that users don't update), lets say adding 50 new records, would it cause the cache to be dropped. The reason I ask is because it the cache remains until its exipry time, I can replace the database and rebuild datasets incorporating new data in the background when the token expires. If the cache is dropped when I update the database, it will mean interuption whilst I reload the datasets and will change my strategy on uploading new data.
I ask the question because I'm currently working on the development server and unable to test in a live server environment at present.
