ListView question?

[VBDT]

Ok guys this is killing me now! I have a ListView control in the form which has the checkbox enabled. This project is basically a windows explorer so when the user double clicks the folder the ListView should show the contents of the folder. So far so good! Now what I want is when the user double clicks the folder the checked state of the checkbox should not be changed. The only time the user changes the checked state of the folder when he clicks on the checkbox. Does any one know any property that should be set to achieve this?
Thanks in advance!

For now I came up with this solution but I like to here some other suggestions too.

Public Class Form1
    Dim doubleClicked As Boolean = False
 
    Private Sub ListView1_ItemCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles ListView1.ItemCheck
        If doubleClicked Then
            e.NewValue = e.CurrentValue
            doubleClicked = False
        End If
    End Sub
 
    Private Sub ListView1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListView1.MouseDown
        If e.Clicks = 2 Then
            doubleClicked = True
        End If
    End Sub
End Class

Well I think there is no other ways of doing it so I stick with this code but I have another question. How can I know if the item is checked by mouse or through the code? Thanks for any replies!
