Thank you.
It wasn't exactly.
I wanted a JSON processor that was better about memory use than ArduinoJSON, and more portable. I've accomplished that in spades, but now I want to make it faster.

I'll be trying to build a screen capture utility for users to make error reports. Not very complex: they'll click an icon and it will grab the entire screen (with error message(s) ) and email (SMTP) it to IT Support. To be built with VS2015. The user's only interaction will be that of clicking the icon and it will not do any sort of screen display (no sizing or any of that required).
I googled a bit and there are quite a few free of libraries out there - has anyone here used any of them, and if so, can they recommend some library (or warn me away) ?
This is a bit of a COVID fallback position: the normal portal I built them allows for a user to submit a problem for another user (such as in an adjacent cubicle) - not nearly so useful when people are working from home.
[EDIT]
It worked by adapting How to capture the current screen using Windows Forms | DotNetCurry[^] to VS2015 - The screen is grabbed before the window opens and the window is to serve as an acknoledgement to the user that something happened. This code is from a much older version of VS, before gcnew, '^', and a few other things that are no longer valid

Windows comes with a snipping tool. Just have them use that.

I can't even get our field service people to use that. I consistently get error reports with 'screen captures' that were taken with a phone camera from three feet away.

So do I and I built in the capability to save the current window with one click of a button on the main display. Somehow that escapes them.

As Gary Wheeler observed, in his reply, and I put to another reply not dissimilar to yours.
The Lounge[^]
The idea is if the users has a problem (error on screen) they click a button - probably in the tool bar, and the rest is all done for them (capture->save->email). The only the windows built-in becomes useful is if I can invoke it and do the rest in code.

I added a button to my app to save window images as PNG files. I use C++ and the Ximage library I found here.

ShareX - The best free and open source screenshot tool for Windows[^]
I wouldn't even bother to write one (though if you wanted to play with it, the source code is in C#.) It's fantastic, and has a configurable "workflow" - copy to clipboard, save to file, etc.
So my recommendation is, just have your users download it or similar free products already out there.

The users aren't supposed to see anything for the screen shot - I will likely put up a "sent" message after I SMTP the file but the idea is to minimize their participation (i.e., need to think).

Ya know, I wrote a WPF customizable Message box article, and I was toying with making the MessageBoxImage icon clickable (in fact, I have most of the mechanicals for it are already implemented. The action performed in response to the click could be anything you want, such as sending the displayed error message to the support team, or even taking a screenshot, if that's what you really want to do. I personally think a detailed and properly crafted error message would be better, but hey, that's just me.

The problem is: Who is going to write that carefully crafted error message ?
The brain-trust that make up the typical employee cadre where I work, and probably most anyplace that that isn't full of techies, can hardly frame a valid question if it's not a text message in both quality and utility.
Or, as I should have put it: the dumb asses don't know how to do anything and, working from home, no one is around to hold their hand to get them through it.
So - of course - what you think should be done would really be great. If only there were someone on the other end who can handle it.
Note: Screen-capture part finally worked out to my satisfaction. SMTP mail is next.

Passover cleaning, spring cleaning, and hay fever. Are these reasons for celebration?!
(Yes, I spotted the pun)

Well, in this climate, Passover coincides with Spring and (at least once per year) one is induced to clean ones house.
As for hay fever - perhaps I forgot to mention I have a great deal of stock in Kleenex?
I just think you have shoveled enough snow to understand how nice it is to see crocus' start to push through the ground an bloom (even if it is snow-covered) - and the smell of the air is not the bite of cold in your nose but the symbolic renewal of life.
I can help you - should you be around here in the winter and it snows, you can try your hand at the fine are of shoveling; if you drive, the unspeakable thrill of spinning out on "black ice". However, no pollen.
