I have a data entry form. I am trying to avoid users accidentally using
the mouse wheel and saving an incomplete record (or saving record that
skips the validation routine).
In Mousewheel event, I have a boolean variable (blnMousewheel) that is
set to true. In the beforeupdate form event, an If statement cancels
any changes if the blnMousewheel is true. It also sets the boolean
variable to false.
It works most of the time, but some...

The documentation clearly explains the MouseWheel event for a picturebox.
Unfortunately I am not able to select this from the declarations dropdown
list for the picturebox control on my form. It's not listed...
Any ideas? Is this a bug? What else can I do to react on a mousewheel
event...?
Thanks, Rud.

I have a usercontrol I'm working on and it has several rows of data. I would
like to scroll the data when the Mouse moves onto the control and the scroll
wheel is turned without setting the focus to my control. If my control
doesn't have the focus, the MouseWheel event isn't fired for mycontrol. I
don't want to set the focus to my control whenever the mouse moves over or
even hovers over it. it as that would be impolite to the enduser...

Cheers and thank in addvance for any help provided

Hello,
when a NumericUpDown control has the focus, the mousewheel
increases/decreases its value. How does one prevent this from happening? How
does one turn off its mousewheel event?
Thanks.

Hi,
I have a Windows Forms application which uses multiple child forms (MDI
interface).
The height of one of the child forms is larger than the height of the MDI
client area, so when this form is visible, the vertical scroll bar of the MDI
parent appears automatically.
What I want to do is write a routine within the MouseWheel event of the MDI

I seem to be missing something... I want to use a mousewheel event in my
VB.NET app... and there's a lot of example code on the net showing how to use
the mousewheel event... and the .NET docs discuss the mousewheel event...
but there doesn't seem to BE a mousewheel event. in VS 2003 or 2005, in C#
or in VB.NET... and on the couple systems I've checked. I can't find a

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,...

I have a picturebox on a form. All the events seems to work such as
MouseEnter, MouseLeave etc. However I can not get the MouseWheel event to
fire. I am hovering the mouse over the picture and turning the wheel. Does
it not work like this?
If I add a Form Mousewheel event then this does fire - even when the mouse
is over the picturebox.

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. 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...
