I have a windows application wherein I have focus on a datagrid. Now when i
hit the down arrow, I want to capture the event. However, my datagrid.KeyDown
event handle is not getting invoked at all.
This is actually the first time I'm ever having to use this event of the
datagrid. Just wanted to know if this does not work?
And if it doesn't, then what's the workaround?
Cheers!

I have a Datagrid that is inside a panel. I want to use the keyDown event to
reconize the arrow keys. But I have no luck at all. The problem is that the
keydown event won't fire at all, unless I click on a row (withs will turn
blue then) and then click on it again . Now if I press any key the event will
fire (except for the arrow keys).
I also tried to override the IsInputKey => no luck.
I also tried to override the ProcessCmdKey => With...

Does anyone know how to detect keypresses in a Datagrid cell? The
Keypress event ofthe datagrid doesn't fire if you are in a cell.
Neither does KeyUp & KeyDown. I've tried hooking in to the
DataGridCell events but it doesn't have the keypress event.

I would like to use datagrid's keydown event to capture the "Ctrl+D" when

I have a form w/ a textbox and Cancel button on it. I have a routine to
handle textbox.validating, and I have the form setup so the Cancel
button is the Cancel button.
WHen the user clicks on the cancel button, the textbox.validating is
being called. I don't want it to be since they are exiting the screen
the validation doesn't have to be done.
How can I do that.

I have several textboxes in which the end user can enter values. When the user presses the Enter key
when in any of the textboxes, or leaves that textbox, I want a routine to run (mathematical analysis
followed by plotting a graph). Since it is relatively slow (less than a second, but makes the
updating sluggish) I only want it to be triggered when the value in one of the textboxes is actually
changed by the user - pressing Enter or leaving...

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...

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,...
