SetPixel question

[Matthew]

I have put the following in my Form1_Load event:

Dim Img As Bitmap = New Bitmap(1, 1)
Img.SetPixel(0, 0, Color.Green)
BackgroundImage = Img
TransparencyKey = Img.GetPixel(0, 0)

This makes the background green. It should make the background transparent.

If you comment out the second line, it actually works properly. However, I
need the image to be green.

Any ideas?

Hi,

Why not try something like this

Private Sub Form1_Paint(ByVal sender As Object, ByVal e As
System.Windows.Forms.PaintEventArgs) Handles MyBase.Paint

Me.TransparencyKey = Color.Green

e.Graphics.FillRectangle(Brushes.Green, Me.ClientRectangle)

End Sub

That's perfect.
Thanks Ken!
