I am developing a winforms project in vb.net. I have several forms that have
a number of controls, grids, etc. When I load these as MDI child forms, they
load slowly AND they paint/repaint on the screen, and it makes a sloppy
presentation. I am unhappy with it, and obviously the client says that it is
unacceptable.
How can I make a nice, crisp form/screen opening?
Thanks so much for you help.

I have a hex editor-type class that extends UserControl and paints its data
to a PictureBox. Basically the problem is that repainting it takes usually
between 60 and 80ms, which may seem pretty fast but is not good enough when
you have to repaint very frequently. For example, when you scroll the
control or select blocks of text quickly.
I have it paint its graphics to an offscreen Graphics instance, which I then
transfer to the...

Hi
I am developing a custom on screen keyboard. So far I have an array of
buttons and then using SendKeys to send the text of the button to the active
control to receive the text.
The only problem is that the application is rather slow at painting the
buttons. Ideally I wanted to allow the user to re-size the control and
change the text and style of the buttons without such rendering issues.
(I have a tool to re-size the buttons,...

When the application I'm working on is run it creates a panel with a Paint
event customized to draw primitives (circles, rectangles, etc.), places the
panel on a form, and then launches the form.
The weird part is, the panel, in the instant it becomes visible, seems to
have an image of what this panel had in it the LAST TIME THE APPLICATION WAS
RUN! Since this panel is created anew every time the application is run
('natch), this seems...

Evening,
I have a slight erk with the ComboBoxRenderer running under Vista and was
hoping someone could shed some light on this for me.
I've created a custom control that inherits from Button - no problems there
:)
The problem comes with the actual painting of the custom button... The Visa
one blends in almost perfectly with the textbox component of a combo - BUT a

I am trying to do some processing on a background thread while keeping the
UI painting. However, this is a generic server side call routine - and it
needs to block until the server side call completes. So the idea is, a
server side call begins, it gets spun off on another thread to keep the UI
painting - but, the code flow cannot return to the caller until the server
side call completes, because the caller expects the data.
The only way...

Hello guys. I was wondering if it is possible to perform custom painting in a GUI window using C++. In Java you can do this by using the following code:import javax.swing.SwingUtilities;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.BorderFactory;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
public class SwingPaintDemo2 {

So I have a form, a dataset with a few table adapters (3 to be precise) and a datagridview.The datagridview has a lot of columns as checkboxes (30 columns are checkboxes per row).
The problem is in the form drawing and painting, when first shown the form paints itself very slow and im running this on a relatively powerful computer (Pentium 2.4GHz with...

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

Overview:
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,...

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.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
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...
