I've explained the problem in the following code snippet. I want to share
single functions for use by several data types.
In this function I call different functions to fill out the original object
"o" that is passed in.
FileGroup is a derivative of an ArrayList object.
Can I fix this problem or will I have to create a mass of overloaded
functions for the whole path from where o originates right through to the
database?

Hi.
I'm trying to figure out how to properly start and stop threads from a
windows form. One thing I still have a problem with is how to make sure
the spawned thread(s) are shut down when the form closes. Here's some
sample code of what I've done so far:
delegate void updateDelegate();
private void UpdatePBar() {

Hello:
What replaces "locking" a text or "combo" box so that input is not allowed?
Do not want to use disable.
How can you trap all keyboard input and set it equal to nothing?

In the code below, clicking on the button ButtonChangeCursor changes the form's
cursor to a WaitCursor. Clicking the button ButtonRestoreCursor changes the
form's cursor back to its original cursor. For the reasons I explain below I
wouldn't expect this code to behave as it does, so why does it work?

Hi -
Please be gentle. I am quite new to visual basic, but I have been
going through tutorials and reading up. I found a code snippet on the
internet that I wanted to see if I could re-purpose for a project, but
I keep getting the error: "Object reference not set to an instance of
an object" for the 7th line of the code below which is:
obj.ConvertPage(URL).Save("C:\screencaptest2.bmp",
System.Drawing.Imaging.ImageFormat.Bmp)

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,...
