Control creation and OnPaint

[Dave]

Hi all,

I'm creating a control derived from System.Windows. Forms.Control
I override the OnPaint() function
The control takes place on a form with a background image.
Because I've some problems to draw properly my control, I decided to test it
with a OnPaint() function which does *absolutely nothing*. And I'm very
surprised : I don't understand why the control seems to draw itself !? I get
a rectangle filled with the background color of the window... Why ? The
OnPaint function does absolutely nothing...

Am I missing something ?

Thanks in Advance.

(And sorry for my poor englih)

Dave

*************** *************** ***********

peace of code :

protected override void OnPaint(System. Windows.Forms.P aintEventArgs e)
{
}

With VB.Net, I think it's omething like this :

Protected Overrides Sub OnPaint(ByVal e As PaintEventArgs)
End Sub

--> You see, the OnPaint function does absolutely nothing ;-)
