Need transparent label but with a slight difference

[Adam Maltby]

Hi,

I need to do a transparent label but with a difference.

I have drawn on my form a custom background using CreateGraphics as I needed an ellipse looking fill in a rectangle - so the actual background colour of the form is still set to "control" colour.

If I use the background transparent setting instead of seeing my drawn on background and it's gradient i see the forms background colour. If the label was on a solid coloured bit of drawing I would set it to that but since it sits over part of the gradient I need i tto be transparent to show the custom drawing.

Any ideas?

Thanks
Adam

Why have you used createGraphics when you already have a Graphics object(e.Graphics) in the Paint method?
If you use that GraphicsObject, the label will appear Transparent.

If you draw the form background in the forms Paint method using the Graphics object e.Graphics, then the transparent label will paint itself with the Gradient that you drew on the form.
If you Draw the forms background outside of the paint method using CreateGraphics, then the transparent label will paint itself with the forms backcolor.

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

Dim FillBrush As New Drawing2D.LinearGradientBrush(ClientRectangle, _
Color.Blue, Color.Red, _
Drawing2D.LinearGradientMode.ForwardDiagonal)
e.Graphics.FillRectangle(FillBrush, ClientRectangle)
FillBrush.Dispose()
End Sub

Excellent! Thanks a lot.
Still getting to grips with the overall options of graphics painting in vbnet (as you no doubt gathered) - that was a big help!

Thanks
