Microsoft.ApplicationBlocks.Data.ODBCHelper ?

Question

I've found mention of a data application block existing for ODBC, but can't seem to find it anywhere. If i didn't have a copy of the Access DB application block I wouldn't believe it ever existed either.

Anyone know where to download either the DLL or the code-base from?

--UPDATE: It is NOT included in either the v1, v2, or Enterprise Library versions of the Data ApplicationBlocks

Thanks, Brian Swanson

Which version of .net are you interested in using the ODBC block on?

The Enterprise library has a Data Access component. It is useful on SQL, Oracle, and ODBC. Just set a different provider name in the .config file EX:

<add name="MyConnection" connectionString="Dsn=Datasource;uid=UserID;pwd=Password" providerName="System.Data.Odbc" />

At that point, the data access code is "standardized" and looks identical for SQL, Oracle, and ODBC

EX:

Imports Microsoft.Practices.EnterpriseLibrary.Data
Imports Microsoft.Practices.EnterpriseLibrary.ExceptionHandling

    Public Class MyClass

    Private dbMyDatabase As Database

    dbMyDatabase = DatabaseFactory.CreateDatabase("MyConnection")

    Public Function GetMyData(ByVal FacilityCode As String) As Data.DataSet

         Try
          Dim SQL As String
          SQL = "SELECT * from MyDataTable"
          Dim cmd As Data.Common.DbCommand = dbMyDatabase.GetSqlStringCommand(SQL)
          Return dbMyDatabase.ExecuteDataSet(cmd)
         Catch ex As Exception
          ExceptionPolicy.HandleException(ex, "All")
          Throw
         End Try
        End Function 

    End Class

The address for the latest Enterprise Library is: http://msdn.microsoft.com/en-us/library/cc467894.aspx

This is assuming you are using .net 3x.

Also note that we are using the Exception Handling block in the above code.
