Hi.
I'm pretty new to C# so this may seem like the dumbest question
today, but I'm stuck.
I have a small application, one Form that opens a connection to
a database in its constructor. If the connection goes wrong I
display a messagebox and I want the application to end after the user
clicks OK.
I cant make that happen.....
If I use Application.Exit in my constructor the form still lives,
if I do a this.dispose the program crashes and...

Hello everybody,
I need to abort execution during start up, while the constructor called by
Application.Run is executing.
If the database fails to connect during my application's startup I want to
display a message (no problem here) and then abort the program. However,
after the attached code executes I end up with my main form and a wait
cursor! If I click on the X the form closes. Boss doesn't think an
unhandled exception will...

(1) What is Happening with the Threads

I am currently reading a chapter involving multithreading, and some sample code calls
Environment::Exit() to terminate the application with all threads.
What is the difference from Application::Exit()? Does Application::Exit() terminate only
the main thread and background threads, and not the foreground threads?

I am confused about the Application.Exit method, where the help states "This
method does not force the application to exit." Aside from the naming
confusion, how do I force the application to exit? See **** below for my
comments/questions in a simple example.
****In Sub Main, the Application.Exit works as expected, other sub main code
is ignored, and when the end sub is reached the application shuts down....

I start the application with Application.Run(New MDIMain) in Sub Main.
MDIMain is the mdi form which loads and then calls Login form.
I'm using Application.Exit to terminate my VB 2005 application on Login
screen if user clicks on Cancel button.
When I do this I get a sound as MessageBox produces. I do not see any
messages, but VB environment works abnormally after that. It doesn't switch
modules until I minimize it and maximize again or...

Hi All,
When I use applcation.exit() in winForm application, the form closed, but
the process is still going!! ( The debug process is still running if debug in
VS IDE). Environment.Exit(0) works fine. But how to do in such following
scenario: if I need to give 2 option for user,1. Quit 2. Restart. In Quit
option, I use Environment.Exit(0) to confirm the process will be stopped. In
Restart option, I can't use Environment.Exit(0) , because...

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:

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,...

Hello
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...
