Hi,
is there any way to find out how form was closed (by calling it's method
Close() or by clicking on the 'close' button in control box)?
Also, can I close the form in that way that Cloing/Closed events are not
triggered?

Greetings
I am sure this is a simple question. But I have "googled" it to death
and have only found one answer that involved a bunch of window's API
calls that I did not understand.
I am a student taking VB.NET and we are studying the Validation event
and how to use it on text boxs. I have set the forms.causevalidation
property to false. But if the user has bad data in the text box and
just wants to quit the program by clicking on...

Hi. I have an MDI Parent form with multiple child windows. When I close
the parent form, the Closing events of the children forms are not executing.
Do I have to close all the child forms in the parent's closing event in
order to get the closing events of the children forms to execute?
Thanks.

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 is the best way to avoid validation when closing a
window? For instance, I have a Windows Forms window which
has a validation event for a text box. However, if one
enters invalid data in then and then attempts to close the
window (either via my custom 'Close' box or by clicking the
close 'X' in the upper right window corner), the validation
event still triggers and it tells the user that they have
invalid data. Which of course means...

I am using a GridView inside a UserControl which has a template column for
deleting the rows. Before databinding the gridview i am attaching the
RowCommand and RowDataBound event.
I am using the RowDataBound event to set the commandargument of the delete
button. The event is being fired and works fine.
When I press the delete button, the RowCommand event is not firing! and
neither is the RowDeleting (the button's commandName is...

Does it make sense to put this
If e.Cancel Then Exit Sub
at the beginning of form closing events so if the user cancels the app's
exiting in one Closing routine he will not be asked again by another when
its form Closing routine is run?
I guess what I'm asking is will that work. If one form sets e.cancelled to
true will e.cancel be true when the next form receives a closing event?

Hi guys,
I am converting a rather complicated database driven Web application from
classic ASP to ASP.NET 2.0 using VB 2005 as the programming language. The
original ASP application works quite well, so at times it is tempting just
to port parts of it over mostly as-is. In fact, one MSDN article I read
suggested using straight HTML wherever possible to make the app more
efficient and less resource demanding.
On one page there are 2...

I have a .NET 2.0 MDI application where the child form has a Tab
Control. Each of the Tab in the Tab Control has a Validating event to
handle what it should do when the user changes tabs.
But these Validating Events are also fired when either the child form
or the main (parent) form Close icon is clicked. And I need for these
events to know if they are being invoked because the app (or child
window) is being closed. I have set a boolean...

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,...

With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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...
