Class Example

    Shared Sub Main(ByVal args() As String)
        ' Get datastore object
        Dim dsmgr As New DatastoreManager(1033)

        ' Get the platforms in the Datastore
        Dim platforms As Collection(Of Platform) = dsmgr.GetPlatforms()

        ' For each platform, output name and ID
        Console.WriteLine("Get all platforms with the GetPlatforms method: " + vbCr + vbLf)
        Dim platform As Platform
        For Each platform In platforms
            Console.WriteLine("Platform Name: " + platform.Name + "    ID: " + _
                              platform.Id.ToString())
        Next platform

        ' Get the Windows Mobile 5.0 Smartphone platform
        Dim wm5sp As New ObjectId(New Guid("BD0CC567-F6FD-4ca3-99D2-063EFDFC0A39"))
        Dim p As Platform = dsmgr.GetPlatform(wm5sp)

        Console.WriteLine("Platform Name: " + p.Name + "    ID: " + p.Id.ToString())
        Console.ReadLine()

    End Sub 'Main
