Use the CreateQuery property to prepare a query to be sent to a server. Use the Execute method to send the query to the server. Use the Definitions property to access the definitions for the expression. Use the Body property to get a specific definition. 

The following sample queries the "dict.org" server for all definitions for "hot" expression. ( The sample uses the "exact" strategy, but asks all available dictionaries ):

Private Sub Form_Load()
    Dim c As EXDICTCLIENTLibCtl.Connection
    Set c = Client1.OpenConnection("dict.org")
    If Not (c Is Nothing) Then
        With c.CreateQuery("hot", , c.Strategies("exact"))
            Dim r As EXDICTCLIENTLibCtl.IResult
            For Each r In .Execute
                Dim d As EXDICTCLIENTLibCtl.IDefinition
                For Each d In r.Definitions
                    Debug.Print d.Body
                Next
            Next
        End With
        c.Close
    End If
    Set c = Nothing
End Sub
