I set on my merry way ... eluding, I thought, the KGB agents following me ...
Thought I'd see if the old Line, Ellipse, Rectangle VBPPk controls could still be used in the latest VS and C#: so I kissed the GitHub stone, and added the references to a WinForm project.
Damndumbed if I could get a Click, or MouseDown, EventHandler to fire at run-time from a Shape.
So, I just rolled my own UserControl, and set its region to a circle: damndumbed if I could get a Click, or MouseDown. to fire at run-time. Well, I remembered some previous problems reported with Mouse Events in a UserControl: I added a Label to the UserControl: damndumbed if I could get a Click, or MouseDown, to fire at run-time.
Okay, so I defined a Component inheriting from Button, and did the region voodoo: damndumbed if I could get a Click, or MouseDown, to fire at run-time.
Now, beginning to feel the disorienting effects of what the KGB put in my vegan smoothie at the airport ... but, unable to remember which airport ...
I put a plain old Button on the Form: damndumbed if I could get a Click, or MouseDown, to fire at run-time.
So, I tried contacting the Microsoft Poison Control Center, but, they said they couldn't understand my Russian ...
In desperation, I removed the VBPPk references, and all code related to them: damndumbed if I could get a Click, or MouseDown, to fire at run-time from a plain old button, or label.
Opened an old project, and confirmed Button, Label, MouseEvents worked as expected.
I grabbed one of the three blind mice dancing on the top of my head, and ate it.
Suddenly, everything changed: now, several hours later, I feel restored to my normal psychotic state.
Knowing I can blame VBPPk, instead of the KGB, is a big relief.
p.s. this may be hallucinatory ... but, on a 4k 15.6 inch laptop screen set below 4k resolution, drag-dropping one of the VB Shapes onto a Form actually shifts the screen resolution in a way it is impossible to precisely position the Shape: you click back on the Form, and where the Shape was changes as the screen snaps back to your standard resolution.

I've experimented with a lot of languages over the years and delivered production code in at least a handful. Of all, I find C# to be the most genial. It has syntax close enough to C/C++ not to alienate those programmers, has plenty of high-level stuff to keep users of languages such as Java happy, and these days has good performance and is open and cross-platform. The only thing I hate about it is the terrible 'destructor' pattern, which you can ignore most of the time. Despite all of this, I rarely if ever read a headline that says C# is gaining in popularity.
There's no point in getting into too many syntax specifics because that would be a never-ending discussion but why does it fail to hit the spot with so many developers and companies?
Thank you to anyone taking the time to read my posts.

My $0.02:
- For all its advantages, C#, like Java, is unsuited to system-level programming. The kernel in both Windows and Linux is programmed in C and ASM.
- Many organizations have an investment in C and C++ code. Conversion to C# would require a major investment. Note that this is also one of the reasons that companies keep using Cobol, so I don't see this changing in the near future.
- C# does have a serious learning curve - not for the language, but for its libraries. If you have learnt to do things in C or C++, converting to C# is far from simple.

I'd agree with all of that. Having used C# for years, I recently had to do some C++ work and got a shock how long it took me just to get through a forest of 'Why the hell doesn't that compile?' questions.

1.1. It's trying to be useful for everything, an egg laying wool milk sow. To do that, it relies too much on libraries for and against everything. A 'one size fits all' approach, while convenient, can get a little bit wasteful. On a PC they easily get away with this, but on a smaller computer with a more modest processor and far less memory things get tough and you don't have enough control over the computer's resources to get very far.
...
4. Too much comfort makes programmers ignorant and lazy. When an allmighty framework does everything for you, you don't have to waste a thought on anything yourself, right? Wrong, when you rub the framework the wrong way and then start to improvise to correct the problem.

In different words I've said the same thing for years. Pointer, namespaces, enumerations, everything all use the dot-separator. For those who don't know better, meaning those who learned this with C/C++ first, they are all the same. They look the same, don't they?
Double colons and -> ? They're not so terribly hard to type and keep one informed of what the hell's going on.

Microsoft seems to think they are. They also seem to think that deleting what you allocate is far too much to ask of programmers.

And to think - when I discovered alloca() and used it in functions I felt like I was cheating !
Oh Brave* New World!

Yes, deleting allocated objects is one of the places that find lots of bugs. Many of these bugs become very difficult to track down. Slow memory leakage is something that eats up lots of support time and turns off many customers.

Yes, I know. That's why I make sure I never have those bugs. My software has to run non-stop for months and months so leaks and errors of any kind always show up.

Actually it is. "Use after free" is one of the biggest security risks in C/C++. Also, not removing what's no longer in use eventually leads to memory exhaustion.
These two situations have been known issues since at least 1958 when Lisp was first developed. This is also why all high level business languages, as opposed to embedded or operating system development, contain at least memory garbage collection. Almost all early languages (COBOL, BASIC, FORTRAN, APL, Algol, etc.) have some concept of garbage collection for some data types. What changes with Java was that all data types are now garbage collected unless the programmer explicitly tell the compiler not to do so.

Nonsense. If that is too much to ask of a programmer then they need to find another line of work.

A big part of the problem is that it’s not always clear who bears the responsibility for releasing the allocation. If you think otherwise, perhaps it’s you who need to consider alternate careers. Or prepare yourself for a big shock if you are just getting started and have just assumed it is that simple.
|

If it isn't clear then you aren't doing it right.

Exactly the kind of rebuttal I would expect from someone who doesn’t have a lot of experience.
Your pronouncement would be more defensible if you had written “somebody” didn’t do it right, but it’s not necessarily the someone who is writing code today and the question of what exactly “it” is has a couple of potential answers. It could be, for example, that a library author meant to conform to an specific predefined protocol and failed. Or it could be they were implementing something new and the documentation they provided is incomplete or incorrect. In especially old code, perhaps they *were* correctly following a known protocol but the protocol itself ended up redefined. Or one of my favorites: a library has multiple functions that accept an allocation as a parameter. Some consume the allocation and others just reference it, and there’s a convention to help you as the library user recognize which are which. But also there’s an old function that doesn’t follow the convention, its behavior is grandfathered in due to being used in existing systems and the footnote mentioning this legacy deviation is cropped off the bottom of the photocopied documentation you were given. I’ve run into all of those scenarios in large scale production systems that I was trying to interface with.
It’s easy to make a simplistic assertion that the only reason this is an issue is that somewhere, sometime, somebody did something wrong. You may be 100% correct about that. But you’re making the very point you’re arguing against. Things like this absolutely happen, and it is in real life one of the most common sources of program misbehavior. We know from decades of experience that this *will* go wrong and that it *will* result in system instability and/or security exposures. So we can cross our fingers and hope after all this time as systems continue to increase in complexity that coders as a population will become perfect at it, or we can automate this tedious, error-prone task for essentially perfect behavior today and let developers spend their time and energy on the real meat of their projects.

Well ... with the new C# version, at least pointer will come back just for you 
|
|
|
|

And, after enough versions and upgrades, you may even finally be back to C++
One can only hope.
