Based on a mouse click I change something on the screen. I then want to
repaint the screen to show the change. When I tried to use .Invalidate in my
mouse routine, I got a compilation error.
Here is my OnPaint code:
protected override void OnPaint(
PaintEventArgs paintEvent )
{
Graphics g = paintEvent.Graphics;

picDocument is a picturebox
When I do picDocument.Invalidate() the box paints.
But if instead I do picDocument.Refresh() the box does not paint.
What does Refresh do. I guessed it did an Invalidate and an Update.
Can someone shed some light?

Refresh says:
-Forces the control to invalidate its client area and immediately redraw
itself and any child controls.
Not the Menu for example?
While Invalidate() says:
-Invalidates the entire surface of the control and causes the control to be
redrawn.
Does "the entire surface" mean more then the client area?

Hi,
I'm getting into GDI+ Forms 2.0 graphics for C#3 using Visual Studio

Pentium IV, with 2 GB RAM, even with doublebuffering turned on.
I did learn tricks such as not invalidating everything, but just the
control that is part of the form you are working on (i.e.,

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
