SQL Connection String

  
We can learn or know how can we connect the database from our .net. This will help for freshers or .NET beginners!

abstract away the source of the connection string using a class with a static property.

  
ASP.NET provides a configuration system we can use to keep our applications flexible at runtime. In this article we will examine some tips and best practices for using the configuration system for the best results.

The element of a web.config file is a place to store connection strings, server names, file paths, and other miscellaneous settings needed by an application to perform work. The items inside appSettings are items that need to be configurable depending upon the environment, for instance, any database connection strings will change as you move your application from a testing and staging server into production.

Let's abstract away the source of the connection string using a class with a static property.

connection string question from a newbie

  

when publishing  in the webmatrix dialogue it asks for "destination connection string" for my "database.mdf"

I was not sure what it was so I pasted this from my web.config file :

Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\database.mdf;Integrated Security=True;User Instance=True

it all published ok, but wont run, so I guess it has somthing to do with this connection string or some kind of configuration issue.

My question is this, What should go in the field for "Destination connection string"


Creating a user friendly alias for the website path

  

 Hello mates,

I am hosting my ASP.NET application on a Windows 2003 Server.

To browse to my application one has to type the path :http://serverName/applicationName


I want users to only type  applicationName on the web adress area.I believe there is something to do with alias and CNAME on DNS records that can adress this.

Any help on how to go about doing this will be highly appreciated.

I dont have the SQL EXPRESS installed instead I have SQL Standard Edition.

 I have two SQL Server instances installed.

 1- UserLT (this is sql 2000)
2- UserLT\SQL2005 (this is SQL 2005 named instance)

But when i try to add a database to my VS website project I get the following error:

and changed the "SQLEXPRESS" to "USERLT\SQL2005".

But I still get the same error message. Any ideas how i can resolve this issue?

How to set SearchRoot Path in Active Directory in this scenario

  

How to set SearchRoot Path in Active Directory in this scenario:

Functionality: We have scenario that 1<sup>st</sup> hit one LDAP server with some 'fixed user name' &' fixed password ' and filter data with specific User name(which given by user) getting 'User dn'.

After that we hit Next LDAP server based on the 'User dn' getting from 1<sup>st</sup> server.

(So, in my case 1<sup>st</sup> LDAP server works like as Load balancing server but functionalitywise it is different)

Intermittant error: "A connection attempt failed because the connected party did not properly respon

  

Greetings,

I'm having a doozy of a problem, and can't find a solution.  I have a WFC Web Service installed to a pair of servers, and accessed through a load balancer.  I am accessing the service from an ASP.NET client app, also via WCF.  The Client is not load balanced.

I'm getting an intermittant error:

(Inner Most Exception) System.Net.Sockets.SocketException:  A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond x.x.x.x:80

A connection could not be made to the report server http://localhost/ReportServer.

  

Hi,

  • I created a Report using Business Intelligence Studio. Its working working well, i can able to view records. But when i try to deploy the report an error occurs specifying that "A connection could not be made to the report server http://localhost/ReportServer. (Microsoft Report Designer)".
  • I open the IIS 7 and find out virtual directories "Reports" and "ReportServer" are available.
  • I check on the browser and type "http://localhost/reports".  I find the browser direct to this url: http://localhost/reports/Pages/Folder.aspx and find error specifying the following one:

         Error:The report server is not responding. Verify that the report server is running and can be accessed from this computer.

  • when i type http://localhost/reportmanager, i found the error:

    HTTP Error 404.0 - Not Found

    The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.

Split URL/Path in Classic AND .net 2.0

  

I need to be able to get the different parts of the URI (and convert from/to relative page paths) in BOTH classic ASP and .Net 2.0 (VB).

For example, if I have "http://sitename.company.com/index.aspx?sec=fred&pag=dis&mode=1" OR "/index.aspx?sec=fred&pag=dis&mode=1"

IS there a function where I can pass in either string (assuming I'm on sitename.company.com) and get back an array with:

(0): sitename.company.com
(1): index.aspx
(2): sec=fred&pag=dis&mode=1

(Or, alternately, three different functions that would return the three parts?)

TIA,
