Hi,
I have a windows application that uses the listview to display about 50
items in detailed view - 4 columns. The first column is static and other
columns will be updated in 100-1000ms - it looks awful when it's running -
flickering too much!!!
Anyone know how to solve this flickering problem? or how should I deal with
this issue? I see some other C++ app can display more than 100 items without
any flickering in such as speed. Can...

Thanks Jay for your response.
I tried your code and it still flickering a lot. To demonstrate it, you can
grab a listview, create 3 columns - name, value, timestamp, in form_load
event to add 50 items into that listview as Item1 - Item49, add a timer to
your windows form, set the timer interval to 100 ms, in the event handler,
add the code to update the value and timestamp
Random r = new Random();
listView1.BeginUpdate();

Has anyone seen a fix for the flickering effect you get when resizing a
Webbrowser control?
It's really irritating and doesn't make for a professional-looking
application.

I have some forms with maybe around 30 controls on each and anytime I load
these forms different parts of it start flickering though not all of them at
once and not the same ones everytime. the forms are each generally separated
into 2-3 different panels and they start flickering with no apparent pattern.
I've tried turning on double buffering, same thing, no improvements. I've
tested it on different computers with different specifications...

I have a problem with my Visual Basic .NET 2003 application which I
have so far been unable to resolve.
I am trying to get an OpenGL control that I have created working
properly as a control on my main form in my VB.NET application. It does
work and render correctly but the problem is that there is an awful
flickering that happens on most PCs I try it on. The flickering is
reminiscent of the sort that you get on a TV when it is not tuned...

I am using Scriptaculous to achieve a pretty simple and straightforward effect. I need a couple of images and text to fade in and fade out periodically, which I already managed to do it using SetInterval, Effect.Appear and Effect.Fade. The only problem is that while the effects are taking place(fading in/out) the cursor keeps flickering in IE(not in firefox) changing rapidly from the normal cursor to the progress cursor and back. is there a way...

The AutoScroll property for the panel is enabled.
When the height or width of "Grid" increases and becomes more than panel size, scrollbars of panel are enabled.
When I scroll using any scrollbar and click on the "Grid" which is inside panel, the position of the scrolled scrollbar changes automatically and...

I'm trying to change the cursor that appears on a standard ListView when the cursor appears over an item. However I am getting a flickering effect as the mouse is changed to a finger cursor, and then back to what I asked it to be.
I'm trying to isolate this flicker/changing to the hand cursor but can't figure out where it's occuring or how to stop it. To replicate this...
1) Create a form with a ListView on it.
2) Add an image list and...

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
Here is the code in...

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,...
