Hello,
What I want to do is quit simple: if the does clicks on the cross at the
right top of the screen I want to catch this event and check a few things
before closing the window. The only thing is, how can I detect somebody has
clicked on it, and how can I possible prevent the window from closing
without hiding the controlbox?
Does somebody have an idea?

Check out the Form's QueryUnload event.

For future reference, almost everybody here is using VB6 or lower. While you
may get a stray answer to VB.NET questions here, you should ask them in
newsgroups devoted exclusively to .NET programming. Look for newsgroups with
the word "dotnet" in their name.
For the news.devx.com news server, try these
vb.dotnet.discu ssion
vb.dotnet.techn ical
For the microsoft news server, try these newsgroups...
microsoft.publi c.dotnet.genera l
microsoft.publi c.dotnet.langua ges.vb
There are some others, but these should get you started.

I have an MDI application with a number of child windows. In each child
window I am catching the Closing event and having the child window decide if
it should set cancel to true. The intent here is to ensure that no child
window can close while it is in a state where user entered information can
be lost. I have just noticed that while the Closing event is caught if I
click the X on the child window, it is not caught if I click the X on...

Hi,
I've developped a Window Form C# application which main form contains
several activex controls. No problems most of the time but on some machine,
the application crashes when the main form is closed with a
NullReferenceException caused by the DisposeAxControl which, i guess, is
supposed to dispose one of my ActiveX.
This is not a big problem as the application is closing anyway but i'd like
to suppress this crash message. However,...

Hi,
I've a form.load event that initializes a cardreader, which is crucial to
the operating of the program.
Now if that throws an exception, the program needs to give a message and
close down.
I tried using Application.Exit(), but that happily executes the rest of the
code (initializing a browser component and adding some images to buttons).
Does anyone have any idea on how to make the program *really* shutdown
without running anything...

For some reason, when I click the X to close my MDI parent form, the action
appears to be re-directed to one of the MDI child forms, and the parent
remains open. I am then unable to close the application.
What should happen, is that the main MDI form should close, taking the child
forms with it. There is code to loop through the child forms, remove the
controls on each of them, and then close the form, but this code should
execute only...

How can I prevent the big close button in the top of the window from
closing the window?
I want to have and "are you sure?" confirmation so the user must press
"Yes" before the program ends. Right now, I've tried catching the
FormClosing and FormClosed events. The message box appears at the right
time, but since the form is already closing, it doesn't matter if the
user presses "Yes" or "No". how do I cancel the FormClosing?

Hello Everyone,
I am writing a Windows Mobile 5.0 application using VS 2..8 in VB.NET.
When someone clicks the "Exit" menu option, which generates a
button_click() event, I find it easy to display an "Are you sure?"
MessgeBox before the application closes. That way, if they
accidentally selected exit, they have a chance to back out. But I also
want to catch the _closing() event on the form in case the user clicks
the application close X...

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:

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,...
