Getting Error Accessing / Opening Database?
Jun 27, 2012
I have a web app that is trying to open a SQL Server Database and it's not working. The error that I am receiving is below:
"A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections."
What needs to be done regarding the highlighted line in the error message?

I have first installed VS2005 and then installed VS2008. After installing, whenever i create a solution in VS2008, i am able to create it properly. if i double-click the solution file, i am able to open the project. Recently i had a problem in my IIS 5.1 and i uninstalled it and the installed it again. After doing that whenever i try to open a VS2008 solution file, i am getting the following error The selected file is a solution file, but was created by a newer version of this application and cannot be opened.". I even tried creating a blank solution using
File->New->Project->Other Project Types-> Visual Studio Solutions-> Blank Solution.
I then added a new project to this solution. I closed the solution and again when i double-click on the newly created solution file i am getting the same error as previous one. I found some solution in the net, tried that and didn't work at all.

I have uploaded all my pages in httpdocs, and created a data bese ... I have also chaned the connection string acordingly but still i am geting following error on opening the page....:-
Server Error in '/' Application.
Runtime Error
Description:
An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
[Code].....
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

I have an application, which connects to a Oracle 10g R2 database, but what it is doing is opening lots and lots of connections and is not disposing them.
My application is using the MVC model, and I have Database Connection Class, which on unload of the page calls my dispose method, which consists the dispose and close commands. Further, on model control, on each of methods requesting data from the database, I am calling the close method on Oracle Data Reader.

I want to be able to create methods to do stuff like opening the connection to the database.Right now if I want to do that I have to put all the code to open the connection with the database in every class.What I did is create a new class called methods, this class is in the App_code folder.I have researched but don't understand how methods are created and how to call them. If someone can give me an example regarding a database connection method, I might be able to really understand how a method works. Basically, this is the code I have to use everytime I want to open a connection to the database:
string connectionString = ConfigurationManager.ConnectionStrings["dbConn"].ConnectionString;

I'm not able to open the file when I click on the link on page in MVC. I get the following message. I've added the impersonation in the code. I'm able to delete and save the file.
Access to the path '\servernamefolder1folder2folder3foder4filename.pdf' is denied. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.UnauthorizedAccessException: Access to the path '......same as above....' is denied.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

I have a grid within another grid. In the detail grid I have image button for which I am giving the URL of documents in the source itself. On clicking on Image button, document can be opened for which I am using a Handler. The code for opening the document is written in the handler.This code is as below:
[code]....
The document can be opened when clicked on Image Button. but, the problem is taht after opening the document, I am unable to perform any other action in the grids.... Other actions like...selection in checkboxes(master grid contains few check boxes),other link buttons in detail grid....etc etc...I am getting the following errr:
PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled
This is because after opening any document,for any action again Handler is being called.

I have an application that uploads an Excel .xls file to the file system, opens the file with an oledbconnection object using the .open() method on the object instance. The upload and writing of the file to the file system works fine but I get an error when trying to open the file on our production server only. The application works fine on two other servers (development and testing servers).
string connectionString = ("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fileName + ";") + "Extended Properties="Excel 8.0""
OleDbConnection connection = null;
connection = new OleDbConnection(connectionString);
connection.Open();
The exception comes on production server at connection.Open() some times, when I reset the asp.net worker process it started to work but after some hours/days It occurs again. how can I fix this issue which comes in production some times but very irritating, or there is some other work around.

I have written an ASP.NET MVC 2 app that uses forms based authentication. It is running on IIS 7.5. When I access the site from the local box, I can see it. When I access it from the outside, I get a generic 401 error. It's odd. Two other MVC2 sites that sit in the same virtual directory work fine no matter where you access it from. I thought it might have been something to do with authorization, but the authorization tag between the three sites are near identical (except for the 'name' attribute). Regardless, I commented out the authorization tag and got the same error (except now, it doesn't try to redirect me to the login page before getting the error).
I'm a bit lost as to what could be going on.

I am currently learning JQuery by reading ebooks. I don't think by reading ebooks is good enough. So can I build a shopping cart website using both JQuery and ASP.NET 4.0 ? I plan to use ASP.NET 4.0 only for accessing the database only.

I have a ASP.NET MVC application which is build up as an assembly that queries the database and a asp.net frontend that references this assembly and this assembly abstracts the underlying database. This means that my Assembly contains a app.config file that contains the connectionstring to the database (Linq to Sql data model). How do I go about making this more flexible? Should i make a "initialize()" method somewhere in my assembly which takes the connection string from the asp.net mvc application and then that controls which database to use? or how is this done?
