Hola,

bueno, yo lo haría así...

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim i As Integer
Dim minutos1, minutos2 As Integer
minutos1 = 0
minutos2 = 30

For i = 0 To 23
If i < 10 Then
Me.cbxHora.Items.Add("0" & i.ToString() & ":" & "0" & minutos1.ToString)
Me.cbxHora.Items.Add("0" & i.ToString() & ":" & minutos2.ToString)
Else
Me.cbxHora.Items.Add(i.ToString() & ":" & "0" & minutos1.ToString)
Me.cbxHora.Items.Add(i.ToString() & ":" & minutos2.ToString)
End If
Next
End Sub

Saludos, espero te sirva
