manager to see the GDI usage of the process. everything seems normal.
now catch the ListView's scroller and start to move it downwards. you have
to hold the constant speed so that the ListView is constantly repainted.

How do I check in a Windows Forms app if any controls have changed? I have
a form that collects data, and I want to prompt the user if they try to exit
the app, or load a new file, without saving changes that have been made.
In MFC/Win32, you'd trap the WM_COMMAND/EN_CHANGE notification messages,
etc. But, this doesn't seem to happen in Windows Forms. I tried Spy-ing a
windows forms app, and the WM_COMMAND messages don't even get sent...

Hi,
I have a form that when opened in the designer appears of the screen. The
form selector can't be dragged (or resized) and if I scroll right and down
to centralise it the form simply jumps further away, completely leaving the
selector box area.
Any ideas? VS 2003 and VB.Net
This is a simple application at the moment but the form is inherited from a

I recently got an error and I don't know how to fix it:
Error 1 'System.Data.DataColumn' does not contain a definition for
'Windows' C:\c#\CsharpPRO\Form1.Designer.cs 304 77 CsharpPRO
I am note sure what to do because all propertiers work, except the
System.Data.DataColumn..
I didn't write any code by hand and used the visual studio to set the

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,...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
