Transparency key and Vista

Question

I'm trying to use transparency key. According to the documentation, you're supposed to be able to use this to put "holes" in the Application where you're supposed to be able to click through the transparent areas in the application and work (eg. "click" on things behind it). However, in Vista Ultimate 64bit , I can't. The following code does not work in Vista, but will in XP Pro.

Public Class Form1
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Me.BackColor = Color.Red
        Me.TransparencyKey = Me.BackColor
    End Sub
End Class

Does anyone have any leads as to why Win XP works with this code, while Win Vista does not allow one to click through the hole in the window?

Hi,

I know that this doesn't make any sense. But it is working for me. What I did was instead of referencing the color using Mr.BackColor, I just used the color again, like this:

Public Class Form1
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Me.BackColor = Color.Red
        Me.TransparencyKey = Color.Red
    End Sub
End Class

Does this work for you?
