If you want to see good examples of event-driven programs, take a look at anything made with Fellippe's InForm. InForm basically does that same stuff but all from scratch. However, we can't use it for this purpose.

Thanks... I think this will work fine. I'll give it a try a little later.
One question I have is, can it be made to work with _FullScreen?
I'm not sure if QB64 has a valid window handle in that mode.

All programs have window handles so you'll definitely have one even when full screen. InForm probably won't look very nice in full screen, though. Scaling issues and whatnot. All controls in InForm are created with BMPs, I think. With Win32, the resources scale with the client. We could make a Win32 version that goes full screen. I'm not sure about what you're wanting to do, however.

If it's okay with you, for now I'm not going to jump into InForm, which I have no experience with yet.
I think I understand how the events are working the way you have it set up.
The problem I'm having is controlling the display, screen resolution and window size.
I tweaked the code so that it still has all the events, but in Sub MouseRawInputTest
there is a main loop that runs concurrently with the events, and updates the screen
(with old fashioned CLS and PRINT statements).
However when it runs, the program just displays a blank white window.
I remembered there was some manual screen updating going on in
Function MainWndProc%&
at Case WM_PAINT,
so I tried disabling the lines there,
so QB64 could just do the screen updating itself,
but the screen is still blank.
I think if we can get the display stuff working, then we're possibly done!
Any ideas how to give control of the display back to QB64?
Here is the latest code:
Code: (Select All) ' ################################################################################################################################################################
' Multimouse
' ################################################################################################################################################################
' Working proof of concept! (Windows only so far)
' Plug in 2 or more USB mice and try moving them around
' -------------------------------------------------------------------------------
' TO DO
' -------------------------------------------------------------------------------
' DONE:
' * detect mouse button clicks (left, middle, right buttons)
' Some issues and things to fix:
' * rework code from event-driven to linear (ie call a routine to get the
' latest coordinates / button states / scroll wheel for mouse n)
' * detect moving the scroll wheel
' * hide the real mouse cursor
' * get this working with _FullScreen _SquarePixels
' * scale the dx and dy of each mouse to 80x25 (or whatever target range is)
' * read the absolute position rather than dx and dy & fix scaling mouse
' coordinates to 80x25 (or whatever our target range is)
' * the code is seeing an extra (phantom) mouse - might be the disabled
' trackpad on my laptop. Is there a way to determine which mice or devices
' are disabled or can be ignored?
' * (later) Figure out how to do this for reading multiple keyboards.
' * (later) Figure out how to get the same functionality for Mac & Linux
' -------------------------------------------------------------------------------
' CHANGES
' -------------------------------------------------------------------------------
' DATE WHO WHAT
' 2004-04-22 jstookey added the ability to detect whether RawMouse is
' available or not so the application can either use a
' different multi-mouse system, or exit gracefully
' (thanks to Mark Healey).
' 2005-04-24 jstookey Modified the code work with the latest version of
' MinGW. The new MinGW incorporates rawinput, so my
' winuser header and library is obsolete.
' 2006-03-05 jstookey Initialized is_absolute and is_virtual_desktop to
' work better with newer versions of VStudio.
' 2022-09-07 madscijr Turned into a command line EXE that is called from
' QB64 with SpriggsySpriggs' pipecom from
' https://github.com/SpriggsySpriggs/Spriggsys-API-Collection/blob/master/Cross-Platform%20(Windows%2C%20Macintosh%2C%20Linux)/pipecomqb64.bas
' This version doesn't work.
' 2022-09-08 Spriggsy Converted C to pure QB64 code.
' 2022-09-09 madscijr Added demo code to move multiple objects on screen
' with separate mice independently.
' 2022-09-09  Spriggsy  Added a screen refresh.
' 2022-09-10 madscijr Added detecting mouse buttons.

Scaling issues and whatnot. All controls in InForm are created with BMPs, I think. With Win32, the resources scale with the client. We could make a Win32 version that goes full screen. I'm not sure about what you're wanting to do, however.
Well, I tried turning on the debug console, and am not seeing any output from the loop at line 579,
so it seems that once it hits line 378:
System Val(Str$(WinMain))
which I _thought_ would just get the events firing,
the flow of the program isn't progressing.
I would expect the events to get set up and then line 301 fires MouseRawInputTest,
which runs a loop until the user presses ESC,
checking for changes in shared array m_arrMouseInfo
(which the mouse events update when mouse movement + buttons are detected).
Any idea how, when we call WinMain, to get it to just set up the events and then return control back to the main program?

' Working proof of concept! (Windows only so far)

' -------------------------------------------------------------------------------
' TO DO
' -------------------------------------------------------------------------------
' DONE:
' * detect mouse button clicks (left, middle, right buttons)
' Some issues and things to fix:
' * rework code from event-driven to linear (ie call a routine to get the
' latest coordinates / button states / scroll wheel for mouse n)
' * detect moving the scroll wheel
' * hide the real mouse cursor
' * get this working with _FullScreen _SquarePixels
' * scale the dx and dy of each mouse to 80x25 (or whatever target range is)
' * read the absolute position rather than dx and dy & fix scaling mouse
' coordinates to 80x25 (or whatever our target range is)
' * the code is seeing an extra (phantom) mouse - might be the disabled
' trackpad on my laptop. Is there a way to determine which mice or devices
' are disabled or can be ignored?
' * (later) Figure out how to do this for reading multiple keyboards.
' * (later) Figure out how to get the same functionality for Mac & Linux

' CHANGES
' -------------------------------------------------------------------------------
' DATE WHO WHAT
' 2004-04-22 jstookey added the ability to detect whether RawMouse is
' available or not so the application can either use a
' different multi-mouse system, or exit gracefully
' (thanks to Mark Healey).
' 2005-04-24 jstookey Modified the code work with the latest version of
' MinGW. The new MinGW incorporates rawinput, so my
' winuser header and library is obsolete.
' 2006-03-05 jstookey Initialized is_absolute and is_virtual_desktop to
' work better with newer versions of VStudio.
' 2022-09-07 madscijr Turned into a command line EXE that is called from
' QB64 with SpriggsySpriggs' pipecom from
' https://github.com/SpriggsySpriggs/Spriggsys-API-Collection/blob/master/Cross-Platform%20(Windows%2C%20Macintosh%2C%20Linux)/pipecomqb64.bas
' This version doesn't work.
' 2022-09-08 Spriggsy Converted C to pure QB64 code.
' 2022-09-09 madscijr Added demo code to move multiple objects on screen
' with separate mice independently.
' 2022-09-09 Spriggsy Added a screen refresh.
' 2022-09-10 madscijr Added detecting mouse buttons.

System won't print anything, it just exits the program with that code. The function is basically being called by STR$. Not sure what you're asking for on the other question, though. The events are all there to run the window created by CreateWindow and the callback function is registered with RegisterClass.
I see now that you mean line 381. Anyways, there's no way for it to be firing anything after WinMain because System kills the program. Everything is a bit out of order anyways. You wouldn't want your test outside of the loop that is displaying the window.

Let me step back a second and present a more concreate example (see below).
Just a simple skeleton for a Pong game that draws some stuff that gets moved around with the mouse.
How would we merge in the API code so the program does the exact same thing,
except instead of _MouseX, _MouseY, it gets 8 seperate mouse coordinates from RawInput?
Hopefully this clarifies the kind of use case I am looking to get input for...
I very much appreciate your help!

Back to this, I need to familiarize with System, I didn't know it took parameters.
What is it doing? What happens if we remove the System and just call the inner function?
How can we use the Screen _NewImage, Line, and Print commands from within the Case WM_PAINT event?
All these questions, to be experimented on and with, when I am back at the PC.
You see what I'm trying to accomplish (e.g. previous reply's more concrete example).
I think with some perseverence and creative thinking, it should be possible.

UPDATE:
I haven't given up on this Spriggsy! Just got a little busy, is all...
This, the MIDI thing, the WAV file thing, all still in the pipe.
I figured it can't hurt to do some reading up on these API calls - below are my notes in case it helps anyone.
I still am not convinced it's impossible to populate hwndMain with _WindowHandle of the existing app, and get the API functions to act on that.
Also, does the RawInput require an actual window to work?
What about the Windows desktop?
Anyway, I will continue to play with this.
If you have any breakthroughs, let me know! :-D
Code: (Select All) ----------------------------------------------------------------------------------------------------------------------------------------------------------------
WINDOWS API COMMANDS
----------------------------------------------------------------------------------------------------------------------------------------------------------------
GetRawInputDeviceList
https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-getrawinputdevicelist
Enumerates the raw input devices attached to the system.
RegisterRawInputDevices
https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-registerrawinputdevices
Registers the devices that supply the raw input data.
GetRawInputData
https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-getrawinputdata
Retrieves the raw input from the specified device.
Parameters:
[in] hRawInput
Type: HRAWINPUT
A handle to the RAWINPUT structure. This comes from the lParam in WM_INPUT.
[in] uiCommand
Type: UINT
The command flag. This parameter can be one of the following values.
Value Meaning
RID_HEADER 0x10000005 Get the header information from the RAWINPUT structure.
RID_INPUT 0x10000003 Get the raw data from the RAWINPUT structure.
[out, optional] pData
Type: LPVOID
A pointer to the data that comes from the RAWINPUT structure.
This depends on the value of uiCommand.
If pData is NULL, the required size of the buffer is returned in *pcbSize.
[in, out] pcbSize
Type: PUINT
The size, in bytes, of the data in pData.
[in] cbSizeHeader
Type: UINT
The size, in bytes, of the RAWINPUTHEADER structure.
Return value
Type: UINT
If pData is NULL and the function is successful, the return value is 0.
If pData is not NULL and the function is successful,
the return value is the number of bytes copied into pData.
If there is an error, the return value is (UINT)-1.
Remarks
GetRawInputData gets the raw input one RAWINPUT structure at a time.
In contrast, GetRawInputBuffer gets an array of RAWINPUT structures.
DrawText
https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-drawtext
The DrawText function draws formatted text in the specified rectangle.
It formats the text according to the specified method (expanding tabs,
justifying characters, breaking lines, and so forth).
To specify additional formatting options, use the DrawTextEx function.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
OTHERS:
FillRect function (winuser.h)
https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-fillrect
The FillRect function fills a rectangle by using the specified brush.
This function includes the left and top borders, but excludes the right and bottom borders of the rectangle.
Parameters
[in] hDC
A handle to the device context.
[in] lprc
A pointer to a RECT structure that contains the logical coordinates of the rectangle to be filled.
[in] hbr
A handle to the brush used to fill the rectangle.
Return value
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.
GetDC function (winuser.h)
https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-getdc
The GetDC function retrieves a handle to a device context (DC) for the client area of a specified window or for the entire screen. You can use the returned handle in subsequent GDI functions to draw in the DC. The device context is an opaque data structure, whose values are used internally by GDI.
The GetDCEx function is an extension to GetDC, which gives an application more control over how and whether clipping occurs in the client area.
Parameters
[in] hWnd
A handle to the window whose DC is to be retrieved.
If this value is NULL, GetDC retrieves the DC for the entire screen.
Return value
If the function succeeds, the return value is a handle to the DC for the specified window's client area.
If the function fails, the return value is NULL.
LoadBitmapA function (winuser.h)
https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-loadbitmapa

A handle to the window.
[in] nCmdShow
Type: int
Controls how the window is to be shown.
This parameter is ignored the first time an application calls ShowWindow,
if the program that launched the application provides a STARTUPINFO structure.
Otherwise, the first time ShowWindow is called, the value should be the value obtained
by the WinMain function in its nCmdShow parameter. In subsequent calls, this parameter
can be one of the following values.
Value Meaning
0 SW_HIDE Hides the window and activates another window.
1 SW_SHOWNORMAL, SW_NORMAL Activates and displays a window. If the window is minimized or maximized, the system restores it to its original size and position. An application should specify this flag when displaying the window for the first time.
2 SW_SHOWMINIMIZED Activates the window and displays it as a minimized window.
3 SW_SHOWMAXIMIZED, SW_MAXIMIZE Activates the window and displays it as a maximized window.
4 SW_SHOWNOACTIVATE Displays a window in its most recent size and position. This value is similar to SW_SHOWNORMAL, except that the window is not activated.
5 SW_SHOW Activates the window and displays it in its current size and position.
6 SW_MINIMIZE Minimizes the specified window and activates the next top-level window in the Z order.
7 SW_SHOWMINNOACTIVE Displays the window as a minimized window. This value is similar to SW_SHOWMINIMIZED, except the window is not activated.
8 SW_SHOWNA Displays the window in its current size and position. This value is similar to SW_SHOW, except that the window is not activated.
9 SW_RESTORE Activates and displays the window. If the window is minimized or maximized, the system restores it to its original size and position. An application should specify this flag when restoring a minimized window.
10 SW_SHOWDEFAULT Sets the show state based on the SW_ value specified in the STARTUPINFO structure passed to the CreateProcess function by the program that started the application.
11 SW_FORCEMINIMIZE Minimizes a window, even if the thread that owns the window is not responding. This flag should only be used when minimizing windows from a different thread.
Return value
Type: BOOL
If the window was previously visible, the return value is nonzero.
If the window was previously hidden, the return value is zero.
UpdateWindow
UpdateWindow function (winuser.h)
https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-updatewindow
The UpdateWindow function updates the client area of the specified window
by sending a WM_PAINT message to the window if the window's update region is not empty.
The function sends a WM_PAINT message directly to the window procedure of the specified window,
bypassing the application queue. If the update region is empty, no message is sent.
Parameters
[in] hWnd
Handle to the window to be updated.
Return value
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.

GetClientRect
GetClientRect function (winuser.h)
https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-getclientrect
Retrieves the coordinates of a window's client area.
The client coordinates specify the upper-left and lower-right corners of the client area.
Because client coordinates are relative to the upper-left corner of a window's client area,
the coordinates of the upper-left corner are (0,0).
Parameters
[in] hWnd
Type: HWND
A handle to the window whose client coordinates are to be retrieved.
[out] lpRect
Type: LPRECT
A pointer to a RECT structure that receives the client coordinates.
The left and top members are zero.
The right and bottom members contain the width and height of the window.
Return value
Type: BOOL
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.
To get extended error information, call GetLastError.
InvalidateRect
InvalidateRect function (winuser.h)
https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-invalidaterect
The InvalidateRect function adds a rectangle to the specified window's update region.
The update region represents the portion of the window's client area that must be redrawn.
Parameters
[in] hWnd
A handle to the window whose update region has changed.
If this parameter is NULL, the system invalidates and redraws all windows,
not just the windows for this application, and sends the WM_ERASEBKGND
and WM_NCPAINT messages before the function returns.
Setting this parameter to NULL is not recommended.
[in] lpRect
A pointer to a RECT structure that contains the client coordinates of the rectangle
to be added to the update region.
If this parameter is NULL, the entire client area is added to the update region.
[in] bErase
Specifies whether the background within the update region is to be erased when the
update region is processed. If this parameter is TRUE, the background is erased when
the BeginPaint function is called.
If this parameter is FALSE, the background remains unchanged.
Return value
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.
OffsetRect
OffsetRect function (winuser.h)
https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-offsetrect
The OffsetRect function moves the specified rectangle by the specified offsets.
Parameters
[in, out] lprc
Pointer to a RECT structure that contains the logical coordinates of the rectangle to be moved.
[in] dx
Specifies the amount to move the rectangle left or right.
This parameter must be a negative value to move the rectangle to the left.
[in] dy
Specifies the amount to move the rectangle up or down.
This parameter must be a negative value to move the rectangle up.
Return value
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.

It isn't that it is impossible to use WindowHandle as our HWND.... It's just that we will most certainly have to register our window to accept messages and that we absolutely must use a callback function. Besides, oftentimes you don't even need to pass in the window's handle because a default of NULL/zero just tells it to use the calling window.
