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 times, in the before update event,
the blnMousewheel is false (when it should be true) and the record is
saved. This could have happened only if the mousewheel event had not
triggered.
I am not sure why the mousewheel event is not triggered. If anyone has
experience with this, please let me know.

You might try this: http://www.lebans.com/mousewheelonoff.htm
Make sure you do not have any margins set in any textboxes. That caused
problems for me. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

Is it possible to disable the mouse wheel WITHOUT using a DLL?
I've looked at Microsoft Knowledge Base Article 278379
(http://support.microsoft.com/default.aspx?scid=kb;en-us;278379), which
explains how to create a DLL and implement code to disable the mouse wheel,
as well as Mr. Lebans' code in MouseWheelHookA2K.zip
(http://www.lebans.com/mousewheelonoff.htm), but both require a DLL.
Sure, it's easy enough to run:

I have a usercontrol I'm working on and it has several rows of data. I would

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...

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.

(I apologize if this posts twice. My AVG is being fussy.)
From what I've read, MouseWheel is a very tricky event. I have
replaced my Python tcl84.dll and tk84.dll files with those in the
ActiveTcl distribution to fix the crashes caused by the event. Then, I
managed to see that my test script (see code below) was registering the
event by printing the delta value (+/- 120).

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

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.

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,...
