Hi!
I need to prevent Task-Switching in my App, so I tried to implement a
low level keyboard hook in a extra class. But it seems that the
Parameters are not passed correctly to my Hook function. Similar
Examples in VB .NET work correctly.
Heres the Source Code:
using System;
using System.Runtime.InteropServices;

All child MDI windows are non-updateable... however, the users may leave the
windows open... and there can be several of them.
I want to implement a system to dispose of MDI child windows after a period
of inactivity, in order to release resources and fire a garbage collect...
Does anyone have any views, or ideas on how to do this??

I have an application that minimizes itself, and I want it to listen
for certain key commands, and when they are pressed, my program can
react to them.
So far I've gotten my application to react as I intend while the
program has focus, but when the application loses focus, the listening
stops.
I am using VS 2008 beta 2, with .net 3.5.

-first check the choice
-if not Ctlr+Z continue

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,...
