I'm trying to trap the Enter key in any of the key events
(keypress, keydown, keyup) of the Windows .Net combobox
control. Try as I might, I cannot get the event to
respond to an Enter key press; nor can I find anything
documenting this situation. Help is appreciated.
Here's my code. This pops up a messagebox for normal
alphanumeric keys, but does nothing at all when Enter is
pressed.

Background:
1. Using C#.
2. I'm having a form which the KeyPreview is on (and must stay like

controls and the form.

rid of.

underneath:

Hello,
I need to trap/detect when a textbox is entered via the tabkey. If the
textbox is not empty when entered via the tabkey then set focus to next
textbox. To enter that textbox would then require a mouseclick if it already
contains text to be edited. I am guessing that I would need to trap for
this in the Enter Event of this particular textbox.
I tried this in the Enter Event of the Textbox, but...

Hello. When I tried to make Tkinter canvas widget respond to
MouseWheel event on Windows XP, I failed. The canvas just doesn't
receive MouseWheel event. I used bind_all to find out which widget
receives this event and the result showed that only the top Tk widget
gets it. This is really annoying. I wonder if this problem exists on
other platform. I googled, but found no appliable solution, so I wrote
one as following. It's not perfect,...

This is the 2nd time posting so sorry for duplications.
I am using VB.NT 2005 & a standard Combobox.
I've been wracking my brain over this problem for a over a month & cannot
seem to find a way to trap the pressing of a Tab Key when the focus is in a
Combobox. The KeyDown or KeyUp event for a combobox will not fire when the
tab key is pressed. The Keyup event will fire when the Tab key is used to tab
into the combo, however I want to trap...

Hi George,
Keyboard input introduces the idea of focus. In Windows, a particular
element is designated as having the focus, meaning that it acts as the
target for keyboard input. The user sets the focus by clicking the mouse or
tapping the stylus on the control in question, or by using navigation keys
such as the Tab and cursor keys.
In principle, any user interface element can receive the focus. The
IsFocused property is defined on...

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...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
