I would like to make the blue part transparent ;[

i've tried

Code:

---

        SetStyle(ControlStyles.SupportsTransparentBackColor, True)
        Me.PictureBox1.BackColor = Color.Transparent

---

but we know it won't work anyway.

any ideas?

You can set the TransparencyKey of the form to be that color, the form will then have a transparent hole in it.

Me.TransparencyKey = Color.Blue 'or whatever the color is

okay cool thanks that worked
