The following subroutine, given a connected instance of an AdomdConnection, iterates through the CubeCollection collection and displays various properties:

Public Sub ListCubes(ByRef ConnectionToCheck As AdomdConnection)

    ' Check the parameter before performing actions on it.
    If ConnectionToCheck Is Nothing Then
        Throw New System.ArgumentNullException("ConnectionToCheck")
    ElseIf ConnectionToCheck.State <> ConnectionState.Open Then
        Throw New System.ArgumentException( _
            "The specified connection is not open.")
    Else
        ' Iterate through the Cubes collection of the
        ' AdomdConnection object.

        Try
            ' Note that this example does not provide 
            ' information about the various collections, such as
            ' NamedSets, provided by the Cube object. Because
            ' these collections are loaded on demand, you should
            ' reference them only if you need information
            ' from them.
