I have spent the last four hours trying to get BitBlt to work to the display from a large bitmap in C# (preview 100x100 pixel image thumbnails from a 3200x3200 bitmap) and going round in circles because all I get is black rectangles. And I keep finding bits on Google which tell me to use SelectObject on the DC, using the bitmap handle, and I can't get that to work because I can't call GetHbitmap on the image, and...
... then I realise that my large bitmap is declared as
private Image big = ... rather than
private Bitmap big = ...
The second definition lets me call GetHbitmap on the image, and pass it to SelectObject ... and it all works, brilliantly... 
Maybe I need a continuous intravenous drip of caffeine?

There is irrefutable proof* that Caffeine Driven Development is the way forward!

You're really trying to make this a thing. 
There are only 10 types of people in the world, those who understand binary and those who don't.

But, but, but...
It is a thing, look[^]. Okay, AJ, myself and few other people use it, but it is still a thing already.

Wouldn't be too hard on myself if I were you. Nothing is really obvious when working with BitBlt...

Maybe the black rectangles were a matter of KSS?

That's what you get for not posting your problem in QA... 
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.

Don't worry. All new developers make mistakes like this. Once you get some experience it won't happen anymore.

I worked with Bitmaps/Images/... in C# lately and basically it is a mess. I'm surprised Microsoft can't handle this better. But perhaps that's just me.

If you go to Google Maps[^] and search for "Null Island" you get ... the US Library of Congress...
Not quite sure what Google is trying to tell us here!

But if you go manually to the point, you see this: Google Maps[^]
