I want to draw some lines on a widget.
This works ok, but when I want to redraw, the old lines are still there.
How do I clear or refresh the widget, so I can draw a new set of lines?
Code snip below.
TIA

Is there a better way to trigger a redraw? This causes flickering when

Hi all!
I've made a simple control derived from a panel class which draws gradient
in a overrided OnPaintBackground event.
Well, I know that I need to redraw control when it's resized by overriding
OnResize event, but
how would I know when to redraw if, let's say, user drags some form over it
or some other action that messes display of this control.
I'm stuck here ... what to do?

I try to understand what could be the source of a problem with
displaying and hiding rows of tables using display:block/none.
I've read selfhtml but could not find any hint about that. Any

type of problem/effect are highly appreciated.

A couple times the hiding/displaying works, but _occasionally_
the entries are hidden but _blank lines appear_, instead.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

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...
