Didn't see anything in there that looked like a "numeric up/down control".

It's in the UcDrawer class. The usercontrol layout was made in the design view. It is the UpDnSettingsNumberOfTools control located in this line:
UpDnSettingsNumberOfTools.DataBindings.Add(new Binding("Value", bindingSource, "NumberOfTools", true, DataSourceUpdateMode.OnPropertyChanged));

Just a guess, since Windows Forms seem to be morphing into WPF ... Changing / selecting tabs fires its own loaded and unloaded events (in WPF) and it looks like your UpDown is on a tab.

@PIEBALDconsult, sorry for trouble, but the article is deleted and I lost your comment "Could be simplified a bit". Can you remind me the link (on stackoverflow.com) to your solution? Thanks.

Most likely I was pointing out that typeof(T).GetFields is better than System.Enum.GetNames
and that using ToString on an enem value is better than trying to do it yourself.

Enum.GetNames calls typeof(T).GetEnumNames, which then calls typeof(T).GetFields, so there's not going to be a huge difference.
However, GetEnumNames sorts the names by the value of the enum member, so there may be a very small performance hit there.

Right. Sorting is unnecessary as we're just adding them to a Dictionary anyway and losing the order.
Not a huge difference performance, particularly as it should happen only once per run and an enum should have few members to begin with.
My earlier comment on an "article" also pointed out that the Dictionary(ies) can be static because they don't change.
I'll also add though, that my implementation also supports having a DescriptionAttribute on each member and that can only be retrieved by retrieving the members (fields), not simply enumerating the names.
Plus... I allow finding an enum value by an abbreviated name, not just the full name, but that's not often useful.

How C# handles binary files?
I already know how to read binary files with the "ReadAllText" command.

Then, unfortunately, you do not know how to read binary files. If you read a binary file as text then it is very likely that the data will be corrupted as the system tries to interpret characters such as return (\r) and line feed (\n). To read binary files correctly you must read them in raw mode into arrays of pure bytes. From there you need to know the structure of the data in the files before you can do anything useful with it.

You very definitely don't read binary file data with ReadAllText - you need ReadAllBytes[^] which returns a byte[] instead of a string.
Strings are made of characters, which are generally variable length: they could be 8 bit, they could be 16 - and reading binary data as text is a very good way to corrupt it beyond hope of recovery.
This may help: ByteArrayBuilder - A StringBuilder for Bytes[^] it allows you to apply some "structure" to a binary file and read it in a "sensible" way. If nothing else, it shows one way to handle binary data files, but if your data files already exist and you must read them, then you will probably need to take a good hard look at the file format before you get started - there will be a structure applied to it, but what structure depends on the developer who produced them!
If you are to produce your own dtaa files, then it's probably a better idea to look at using JSON or even XML instead of binary data - it's much, much easier to handle I/O as both can "fill classes" for you when your read or write the data. Saves a whole load of work!

how to create this program??
a program that will ask the user to enter positive number and loop/ continue until the user input a negative value and stops the loop.
The program will display
● The total number of positive numbers input
● The maximum (Highest) value
● The minimum (Lowest) value
● The equation
● And the average
Note:
● When the input is ZERO, the program will display a message that tells the user must input a positive or negative value, and ask the user to enter again a value
● ZERO will be discarded

We are more than willing to help those that are stuck: but that doesn't mean that we are here to do it all for you! We can't do all the work, you are either getting paid for this, or it's part of your grades and it wouldn't be at all fair for us to do it all for you.
So we need you to do the work, and we will help you when you get stuck. That doesn't mean we will give you a step by step solution you can hand in!
Start by explaining where you are at the moment, and what the next step in the process is. Then tell us what you have tried to get that next step working, and what happened when you did.

I'd use a Consol application. The only thing I don't understand is what displays "The equation" means?
|

I suspect 'equation' means sum. Probably a translation issue.

I want to make a server and client side WITSML (for Oil & Gas Wells Drilling Data Send/Receive). There are some SDKs here: (WITSML api library for .Net / C# client apps?). I surfed though the internet, but i have not been found any code example or guide to use them.
My Question:
==>.Are There any code example to develop a WITSML and/or WITS server and Client side software in C#?
Thank you in advance.

If Google does not find any then you can assume probably not. It is always possible that you are the first to want to do this.

I have this code
public partial class TrimOptions : Form
{
public bool trimFirst { get; set; } = false;
public bool trimLast { get; set; } = false;
public bool ifBlank { get; set; } = true;
public TrimOptions()
{
InitializeComponent();
chkTrimFirst.DataBindings.Add(new Binding("Checked", trimFirst, null, false, DataSourceUpdateMode.OnPropertyChanged));
chkTrimLast.DataBindings.Add(new Binding("Checked", trimLast, null, false, DataSourceUpdateMode.OnPropertyChanged));
chkIfBlank.DataBindings.Add(new Binding("Checked", ifBlank, null, false, DataSourceUpdateMode.OnPropertyChanged));
}Whatever I set the properties to in code is reflected in the UI when the form is displayed. So far, so good. However, the user clicking the checkboxes does not set the properties, and setting the properties programmatically does not change the UI (nor the Checked property of the control).
I would like programmatic changes to the properties to update the UI, and I would like the user changing the UI to update the properties. How to do that?

Thank you!
chkTrimFirst.DataBindings.Add(new Binding("Checked", this, "trimFirst", false, DataSourceUpdateMode.OnPropertyChanged));
chkTrimLast.DataBindings.Add(new Binding("Checked", this, "trimLast", false, DataSourceUpdateMode.OnPropertyChanged));
chkIfBlank.DataBindings.Add(new Binding("Checked", this, "ifBlank", false, DataSourceUpdateMode.OnPropertyChanged));This is working just fine now.

Excellent! I see you recognized "this" (the data source) as the form.
