kind of works? reading multiple mice: any c programmers want to look at this?

You don't have to put the headers in the same folder as the other includes. All you have to do is either have it with QB64 or just put it into a subfolder and use the relative path. I typically just keep headers and bas files in the QB64 parent directory. Or I make a subfolder and reference them using the relative paths. For instance, if I have a header in a folder called "Headers" and that folder is in the QB64 parent directory, the declare can look like this:
DECLARE LIBRARY ".\Headers\headername". Also, since you put the headers in the other header folders, you shouldn't use the absolute paths anyways. Just get rid of everything in the path up until the first subfolder of the QB64 parent directory.
For instance:
DECLARE LIBRARY ".\internal\c\c_compiler\x86_64-w64-mingw32\include\headername"

However, I always recommend keeping bas and header files with QB64. Not everyone likes that. I prefer it that way.

Here's a version that also tracks the WM_MOUSEMOVE message and displays the X and Y coordinates in the console window. I could obviously change that to just print the text in the window but decided not to. I'm not sure how WM_MOUSEMOVE handles multiple mice, to be honest. Especially considering it just returns an X, Y coordinate relative to the program window. The WM_INPUT message with GetRawInputData only grabs the relative movement from the previous X, Y coordinate. Give 'er a go and let me know.

Got it, thanks. 

Now for the fun part! 
The code flow seems to be set up like the C program, which is event-driven. 
I see around line 211 there is a DrawText to write the mousemessage to the screen (inside Function MainWndProc). 

How might this be restructured to work like a regular QB64 program that uses a more straightforward linear flow? 

Specifically, how would we merge your mouse magic into the below program, to make option 4 work with it? 

Option 4 calls Sub MouseRawInputTest at line 104, which reads the mice to move some text characters around the screen. 

That routine can be left alone, but we would need to alter these 3 routines to work with your API functions:

At line 290: Function GetRawMouseCount% ()

At line 304: Sub GetRawMouseIDs (arrRawMouseID( 8) As Long)

At line 340: Sub ReadRawMouse (MouseID&, x%, y%, left%, middle%, right%, wheel%, wheelmin%, wheelmax%)

Any thoughts?

I structured it this way as a direct translation of that other C program so as to make some of the more complicated aspects easier to understand. It can definitely be edited to be closer to how a QB64 program is usually structured. I am just more used to converting C/C++ examples to QB64 so I'm now in the habit of programming like a C coder more than a BASIC coder. I'm more comfortable that way. I'll have to look at your code and see what is going so I can attempt to make it more QB64 friendly.

By the way, something I just noticed is that you have System on the line above your Print and End. Print and End won't be hit since System closes the program entirely.

Any help or guidance with that part would be a godsend, because I am totally out of my element here...

That was something I learned since I originally made this program almost a year go, I just forgot to clean that up.
I reuse stuff a lot and cut/paste code a lot, and sometimes I miss stuff. 
Just like how you mentioned how your own coding had changed since you made that old program of yours I had saved - 
I look at things I wrote 2 years or even 3 months ago and it reminds me how much I've learned since then. 
The real fun is looking at code you wrote back in school, or when you had your first job. 
It really brings you back and shows how far you've come.

Hahaha! Definitely. I sometimes find some of my first programs and I cringe so much when I see how badly they were written.

We have to learn somehow!

So instead of an ordinal index to track & identify each mouse, we can use a unique device handle. 
Looking good!

This version now prints the device handles and types to the screen as well as displays the X, Y coordinates from WM_MOUSEMOVE.

I don't understand all the parameters, but I think the main thing to tie in a regular QB64 program to the RawInput mouse routines, after taking away all the event-driven stuff, would be the window handle for the QB64 program. QB64 has a function _WindowHandle which provides that - will that work with RawInput? Will it return a valid window handle even in _FullScreen _SquarePixels mode?
