I have created a DataGridColumnDatePicker Component so
that I can put a datetimepicker control in my datagrid.
It almost works.
When I put my mouse in the cell it changes to a
datetimepicker control. I can then select a date which
displays in the cell. When I leave the cell however I get
the following error:

I have developed a custom control to be used in my application. My
application includes a form designer, so the control can be hosted while
designmode for the control is either true or false, depending on whether they
are using the form designer, or in "run mode". The custom control includes a
slider control that is supposed to be active in our form designer
(designmode=true) and inactive in our run mode (designmode=false). The

I am developing an application that is primarily keyboard not mouse driven. Navigation is very difficult within some controls (list boxes, radio groups etc) unless the focus rectangle is visible. When an application starts the focus rectangle for a control is never visible and only becomes visible once the TAB key is pressed. After that everything works OK. In a list box I have looked at the ChangeUICues event of the control and there is a...

In VB .Net I made a custom CheckBox column style (for the Datagrid control) that maps to two DataTable columns , one it uses for the Checked status and the other it uses for the Enabled status. I am having a couple problems so far.
1. with the way the Paint method works: When I scroll to the right, the custom column gets Drawn on top of the left-most "Selecting" column (the one where the green arrows are displayed). How can I possibly modify...

im doing wrong here... anyways, I am making a custom slider control that
takes dates as its values instead of integers... then taking that date range

I have a custom Control that is a label, however I inherit from Control...
1) I override onClick and do a DrawFocusRectangle, that works great. How do
I clear the focus rectangle once something else on the parent is clicked? I
tried to override OnLostFocus and invalidate but that doesn't seem to do it.
2) the control, like i said is a label, how do i override the hotkey
behavior. I.e, if my text is &Help, when I do Alt-H on the parent,...

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,...

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...
