  how do i use a UDL file?

  Jul 01, 2009 03:00 AM|young345|LINK

  I have a udl file which I want to use so I can connect to the database.

  I have written the code in the webconfig file so it will link to this udl file.

   

  However, I don’t think that is enough, I think I have to write in the code somewhere that I want to use this UDL file.

   

  I have never done this before, does anyone know how I can do this, is there some kind of techinique?

   

  I am using c# and visual studio 2005.

   

  Thank you

  Hi Y.

  Found an old guide for using an UDL file for database access:
  http://aspalliance.com/434_Database_Access_Using_UDL_Files.all

  Hope this helps

  You open the UDL file with the notepad.  There you can find the connection string, then you can copy the connection string to your web.config file and from there you can call the connection string and connect to your database using the connection object.  See the web.config files snippet,

  <connectionStrings>
          <add name="myConn" connectionString="String From your udl file"/>
      </connectionStrings>

  
  Now, in your application file (C#) you can call the connection string as follows,

  string myConnString=ConfigurationaManager.ConnectionString["myConn"].ToString();
  using(ODBCConnection conn=new ODBCConnection())
  {
         //Do your database processing here.
  }

  Why would you use a UDL? Just connect the .NET way:

  AccessDataSource, SqlDataSource and connecting to Access databases in ASP.NET

  <div class=dp-highlighter>

  1. string myConnString=ConfigurationaManager.ConnectionString["myConn"].ToString();   
  2. using(ODBCConnection conn=new ODBCConnection())   
  3. {   
  4.        //Do your database processing here.   
  5. }  

  </div>

  string myConnString=ConfigurationaManager.ConnectionString["myConn"].ToString();
  using(ODBCConnection conn=new ODBCConnection())
  {
         //Do your database processing here.
  }

  
  

   

  ODBC - Access - ASP.NET

  Not a very good combination, always use OleDb

  I am not sure that oleDb works for access or not.  That's why I provided the sample example.

  A common Connectionstring would look something like

  Provider=Microsoft.Jet.OleDb.4.0;Data Source=|DataDirectory|myDB.mdb

  Also, th AccessDatasource control uses the OleDb provider
