VB

Public Sub Add_In_ListView(ByVal Field1 As String, ByVal Field2 As String, ByVal Field3 As String, ByVal Field4 As String, ByVal Field5 As String, ByVal Field6 As String, ByVal Field7 As Boolean)
    lv = ListView1.Items.Add(Field1)
    lv.SubItems.Add(Field2)
    lv.SubItems.Add(Field3)
    lv.SubItems.Add(Field4)
    lv.SubItems.Add(Field5)
    lv.SubItems.Add(Field6)
    If Field7 = True Then
        lv.SubItems.Add(6).Text = "Enable"
        lv.SubItems(6).ForeColor = Color.Green
    Else
        lv.SubItems.Add(6).Text = "Disable"
        lv.SubItems(6).ForeColor = Color.Red
    End If
    lv.SubItems.Add("")
    lv.SubItems.Add("")
    lv.SubItems.Add("")
    lv.SubItems.Add("")
    lv.SubItems.Add("")
    ListView1.Refresh()
End Sub

When my subroutine run add correctly the line with the word enable or disable in the listviw BUT they did not change the color.
Why???

Thanks and regards

[EDIT]
Mea culpa

I have forget the
lv.UseItemStyleForSubItems = False
