I have a usercontrol that contains two pictureboxes
One is on top of the other.
The bottom one is the parent of the top one.
The top one is transparent.
I invalidate the top one often
I don't need all the bells and whistles of a picturebox so I change the top
one to a panel
Now when I invalidate I get much flashing.
Is there something about the way a picurebox draws itself that is different
from how a panel does it?
Can I fix the panel?
Even if I can, does it make more sense to use the picturebox?
Thanks in advance

> Is there something about the way a picurebox draws itself that is different from how a panel does it?
Considering your experience, I would say that is the logical conclusion.
(IOW, yes)
Can I fix the panel?
Yes, but -
Even if I can, does it make more sense to use the picturebox?
Yes, it does.

I think the picture box uses a technique called double-buffering which uses
more memory when drawing but provides the ability to have a faster rate of
draw. This is set as a property on the control so you may be able to set it
on the panel. If you cant, you can set it on your user control.

A Panel does not have a caption, and so doesn't really need a Text property.
Yet, it does have this property. Furthermore, on-line MSDN says it is
'overridden'. The 'detail' of this also just says it's overridden with no
other information about it. Does this mean it allows reference to it, but it
does nothing?
In any case, it is good that it does have this property, since I wrote a
RadioButton 'holder' with GroupBox and needed to create...

I have a composite control.
Which has 2 parts. Under some conditions first part must be shown sometimes
another. So naturally I used 2 Panel object.
And hide one of them.
The problem is that hidden Panel object renders itself as <br>. Not sure
what is the purpose of it. But it ads extra line which is not acceptable.
Is there another control which when hidden is HIDDEN and does not render
anything.

Hello,
I have a form with a panel which contains a radiobutton. When I click the
radiobutton, I invoke the Paint event of the panel using me.Invalidate. The
paint event gets called and runs through code to draw a line. But the line
does not draw on the panel until I press either the Alt key or Tab key. Here

Hi,
first, python is one of my fav languages, and i'll definitely keep
developing with it. But, there's 1 one thing what I -really- miss:
data hiding. I know member vars are private when you prefix them with
2 underscores, but I hate prefixing my vars, I'd rather add a keyword
before it.
Python advertises himself as a full OOP language, but why does it miss
one of the basic principles of OOP? Will it ever be added to python?

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.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
