Hi!
What is the best way to check whether a key is pressed without blocking
in C++?
I know I can use cin.get(c) to get a character from standard input, but
this blocks.
And I know _kbhit() exists in MSVC++, but that's in <conio.h> and
probably not standard, is it?

1. Does MyISAM support FOREIGN KEY constraints? When I read the online
MySQL Reference Manual, it said "InnoDB also supports FOREIGN KEY
constraints". Does it mean MyISAM does not support FOREIGN KEY constraints?
It this is the case, what should I keep in mind when I design MyISAM tables?
2. I have seen the following CREATE statement somewhere, but I have never
known that the "KEY" keyword can be used that way(the last 4 "KEY"). I...

Hello,
I'm currently writing a directx program with C++, but it takes a while to
load the files necessary for the directx. When the directx window loads, it
can quit the program with the 'escape' key by using the keydown events
provided by directx libraries.
What I would like to do is be able to quit the program before it finishes
loading if the user presses the 'escape' key during the load. I will use a
boolean variable to determine...

Hi There!
I'm using VB.NET to create a TreeView application and unfortunately I could
not find "Key" property in Node items of the TreeView.
We used to have "Key" property in TreeView node object in VB6.
What is the equivalent of "Key" property of TreeView node in VB.NET? Has the
property name "Key" has been changed to something else? Or VB.NET does not
support the "Key" property anymore? If so what are the alternatives?

I have SBS 2003 and am using the built in tape backup. My question is about
the registry key "Eject Tape Flag". I understand that this is an
undocumented key and the only articles I can find about it on the internet
reference NT 4.0. Does anyone know if this key works? I have users that
would like to eject the tape after a backup and perfer not to have to do it
through a .bat file. Also, if the key works, what, if any, additional steps...

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