Use the Group property to access a news group by its name. The Group property of the control doesn't list all the news groups on the server. Use the Groups property to access the collection of the news groups available on the server. Use the Articles property to access any article in the group. 

The following sample displays all articles in the "c++.announcements" news group:

Dim n As New EXNNTPLibCtl.NNTP

Private Sub Form_Load()
    Dim g As EXNNTPLibCtl.Group, a As EXNNTPLibCtl.Article
    n.Connect "news.devx.com"
    Set g = n.Group("c++.announcements")
    For Each a In g.Articles
        Debug.Print a.Article
    Next
    n.Disconnect
End Sub
