seperate input from multiple mice v0.54 graphic demo

[madscijr]

I updated the graphic demo with the keyboard and absolute position code, and it's coming along. 

Windows only so far, resolution 1024x768 or greater.

Give it a try! 

1. Plug 2-8 USB mice into your PC.
   
   
2. Place "makeint.h" and "winproc.h" in same folder as programs.
   
   
3. Compile the mouse reader program "ReadMiceSub" first (or run it once, it will run briefly then exit).
   
   
4. Run the front end program "ReadMiceMain".
   The main program will automatically start the subprogram "ReadMiceSub" which should have the focus.
   
   
5. If your PC prompts for permission say Yes. 
   Be patient, the program takes a few seconds to start everything up and get "situated"!
   
   
6. Click the mouse to make sure "ReadMiceSub" has the focus (it's invisible but sitting on top of "ReadMiceMain").
   
   
7. Try moving each mouse.
   Each mouse should control a different colored numbered block.
   
   
8. Try clicking the left / middle / right mouse buttons.
   You should see the button states on the screen for each mouse.
   
   
9. Try pressing some keys on the keyboard.
   The last keys pressed + released are displayed at the top.
   
   
10. Press Esc to quit, or delete the file "ReadMiceSub.DELETE-TO-CLOSE".
    The main program creates this file at startup, and both the main and sub programs periodically check that it is present.
    If it is missing, both programs shut down.
    

Some issues and things to fix:

• The subprogram "ReadMiceSub" sends its data back to "ReadMiceMain" via TCPIP in the form of a tab-delimited string. Tab is chr$(9). Sometimes it sends multiple messages, which are separated by chr$(13). Currently "ReadMiceMain" just processes the first line. Need to split the input by chr$(13) and process each line seperately, which should make concurrent input smoother.
  
  
• Hide the real mouse cursor and reactivate it when program closes.
  
  
• Detect moving the scroll wheel.
  
  
• Get it working with _FullScreen _SquarePixels. When I tried that mode things got really weird.
  
  
• Read input from multiple keyboards - need to figure out how to do the unions in the RAWINPUT structure type in "ReadMicesub". (Just need someone to figure this out, I have tried.)
  
  
• Figure out how to get the same functionality for Mac & Linux.
  

For anyone who doesn't want to download a zip file, here's the code for the 4 files you'll need: 

"makeint.h":

Code: (Select All)

LPSTR MAKEINTRSC(ptrszint i){
    return MAKEINTRESOURCE(i);
}

"winproc.h":

Code: (Select All)

ptrszint FUNC_MAINWNDPROC(ptrszint*_FUNC_MAINWNDPROC_OFFSET_HWND,uint32*_FUNC_MAINWNDPROC_ULONG_NMSG,uptrszint*_FUNC_MAINWNDPROC_UOFFSET_WPARAM,ptrszint*_FUNC_MAINWNDPROC_OFFSET_LPARAM);

LRESULT CALLBACK MainWndProc(HWND hwnd, UINT nMsg, WPARAM wParam, LPARAM lParam){
    return FUNC_MAINWNDPROC((ptrszint *) (&hwnd), &nMsg, &wParam, (ptrszint *)(&lParam));
}

void * WindowProc(){
    return (void *) MainWndProc;
}

'
' HOW TO USE:
'
' 1. Plug 2-8 USB mice into your PC.

' 7. Try clicking the left / middle / right mouse buttons.
'    You should see the button states on the screen for each mouse.

' 8. Try pressing some keys on the keyboard
'    The last key pressed + released is displayed at the top.

'
' DEBUGGING CODE:
' There is currently a ton of commented out debugging code - sorry about the
' mess! There were some horribly elusive problems to figure out.
' To enable debugging output: change Const cDebugEnabled to TRUE
' and search for "debug" and uncomment those lines.
' DebugPrint outputs to the console, DebugLog outputs to a file.
' Enabling console in "ReadMiceSub" caused all sorts of problems,
' so to debug that, just use DebugLog.

' Some issues and things to fix:
' * The subprogram "ReadMiceSub" sends its data back to "ReadMiceMain"

' 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.
'                        Code at: https://jstookey.com/multiple-mice-raw-input/
' 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.
' 2024-05-19  madscijr   Try having the program write mice coordinates / button
'                        states to a file that main program "always on top"
'                        without focus can read.
' 2024-05-23  madscijr   Now we get mice coordinates from subprogram via TCPIP.
'                        A lot faster than using files!
'                        Thanks to DSMan195276 for the networking code.
' 2024-06-19  madscijr   Now we get absolute mouse coordinates not just dx, dy
'                        and can read the keyboard (just a single keyboard).
'                        Updated the graphics / display code to use layers.

'SUMMARY:
'   Purpose:  A library of custom functions that transform strings.
'   Author:   Dustinian Camburides (dustinian@gmail.com)
'   Platform: QB64 (www.qb64.org)
'   Revision: 1.6
'   Updated:  5/28/2012

'SUMMARY:
'[Replace$] replaces all instances of the [Find] sub-string with the [Add] sub-string within the [Text] string.
'INPUT:
'Text: The input string; the text that's being manipulated.
'Find: The specified sub-string; the string sought within the [Text] string.
'Add: The sub-string that's being added to the [Text] string.

Function Replace$ (Text1 As String, Find1 As String, Add1 As String)
    ' VARIABLES:
    Dim Text2 As String
    Dim Find2 As String
    Dim Add2 As String
    Dim lngLocation As Long ' The address of the [Find] substring within the [Text] string.
    Dim strBefore As String ' The characters before the string to be replaced.
    Dim strAfter As String ' The characters after the string to be replaced.

    ' INITIALIZE:
    ' MAKE COPIESSO THE ORIGINAL IS NOT MODIFIED (LIKE ByVal IN VBA)
    Text2 = Text1
    Find2 = Find1
    Add2 = Add1

    lngLocation = InStr(1, Text2, Find2)

    ' PROCESSING:
    ' While [Find2] appears in [Text2]...
    While lngLocation
        ' Extract all Text2 before the [Find2] substring:
        strBefore = Left$(Text2, lngLocation - 1)

        ' Extract all text after the [Find2] substring:
        strAfter = Right$(Text2, ((Len(Text2) - (lngLocation + Len(Find2) - 1))))

        ' Return the substring:
        Text2 = strBefore + Add2 + strAfter

        ' Locate the next instance of [Find2]:
        lngLocation = InStr(1, Text2, Find2)

        ' Next instance of [Find2]...

' Given a string of words separated by spaces (or any other character),
' splits it into an array of the words. I've no doubt many people have
' written a version of this over the years and no doubt there's a million
' ways to do it, but I thought I'd put mine here so we have at least one
' version. There's also a join function that does the opposite
' array -> single string.
'
' Code is hopefully reasonably self explanatory with comments and a little demo.
' Note, this is akin to Python/JavaScript split/join, PHP explode/implode.

'Split in$ into pieces, chopping at every occurrence of delimiter$. Multiple consecutive occurrences
'of delimiter$ are treated as a single instance. The chopped pieces are stored in result$().
'
'delimiter$ must be one character long.
'result$() must have been REDIMmed previously.

' Modified to handle multi-character delimiters

Sub split (in$, delimiter$, result$())
    Dim start As Integer
    Dim finish As Integer
    Dim iDelimLen As Integer
    ReDim result$(-1)

    iDelimLen = Len(delimiter$)

    Do
        'While Mid$(in$, start, 1) = delimiter$
        While Mid$(in$, start, iDelimLen) = delimiter$
            'start = start + 1
            start = start + iDelimLen

'SUMMARY:
'   Purpose:  A library of custom functions that transform strings.
'   Author:   Dustinian Camburides (dustinian@gmail.com)
'   Platform: QB64 (www.qb64.org)
'   Revision: 1.6
'   Updated:  5/28/2012

'SUMMARY:
'[Replace$] replaces all instances of the [Find] sub-string with the [Add] sub-string within the [Text] string.
'INPUT:
'Text: The input string; the text that's being manipulated.
'Find: The specified sub-string; the string sought within the [Text] string.
'Add: The sub-string that's being added to the [Text] string.

Function Replace$ (Text1 As String, Find1 As String, Add1 As String)
    ' VARIABLES:
    Dim Text2 As String
    Dim Find2 As String
    Dim Add2 As String
    Dim lngLocation As Long ' The address of the [Find] substring within the [Text] string.
    Dim strBefore As String ' The characters before the string to be replaced.
    Dim strAfter As String ' The characters after the string to be replaced.

    ' INITIALIZE:
    ' MAKE COPIESSO THE ORIGINAL IS NOT MODIFIED (LIKE ByVal IN VBA)
    Text2 = Text1
    Find2 = Find1
    Add2 = Add1

    lngLocation = InStr(1, Text2, Find2)

    ' PROCESSING:
    ' While [Find2] appears in [Text2]...
    While lngLocation
        ' Extract all Text2 before the [Find2] substring:
        strBefore = Left$(Text2, lngLocation - 1)

        ' Extract all text after the [Find2] substring:
        strAfter = Right$(Text2, ((Len(Text2) - (lngLocation + Len(Find2) - 1))))

        ' Return the substring:
        Text2 = strBefore + Add2 + strAfter

        ' Locate the next instance of [Find2]:
        lngLocation = InStr(1, Text2, Find2)

        ' Next instance of [Find2]...
    Wend

    ' OUTPUT:
    Replace$ = Text2

' Given a string of words separated by spaces (or any other character),
' splits it into an array of the words. I've no doubt many people have
' written a version of this over the years and no doubt there's a million
' ways to do it, but I thought I'd put mine here so we have at least one
' version. There's also a join function that does the opposite
' array -> single string.

'Split in$ into pieces, chopping at every occurrence of delimiter$. Multiple consecutive occurrences
'of delimiter$ are treated as a single instance. The chopped pieces are stored in result$().

' QB64 GPT Just Rewrote My Code
' https://qb64phoenix.com/forum/showthread.php?tid=2728

' And the revisions QB64 GPT made (after minor changes and me asking it to redo some syntax errors):
' It separated out a lot of processing out to separate subs.
' It is quite impressive how little input I had to give it to fix its mistakes.
' The code actually worked just as well as it did before the changes, which blows my mind.
' It actually even listened to me when I told it that it would need to cast an OFFSET type by using VAL(STR$(var)).
' To be fair, I had to tell it "ByRef" was invalid and a couple of other things.
' I also had to declare "y" each time it was used. But the last iteration only required me to declare "y".
' I think that is a decent enough result. Too bad I can't get it to be this good every time.
' 1) This is the paid version of GPT4. I am on the plus plan, so whatever that one has.
' 2) I think I deleted the session. Sorry. I only used it for as long as I needed it.
' 3) I don't know what the hard limit is. It's in "tokens", which I have no idea how those are calculated.
' I got a pretty large source code from one output and it can take a lot of input. I would just say it can handle quite a bit.
' The GPT I used was one I trained using the Wiki, sample code, etc. At the time, it used GPT4.
' Custom GPTs now use 4o. I will probably need to republish it to take advantage of 4o for it.
' I guess training is the wrong word. A custom GPT has a "knowledge base".
' You can have a maximum of 20 files.
' It can use those files to create an answer. Even a zip folder can be used.
' It will basically only use the knowledge base when specifically asked. Otherwise, it is using whatever it already had in its model.
' As for testing code and such, you can create "actions" for your GPT that allow it to do things outside of ChatGPT, including REST API.
' So if dbox ever made a REST API for QBJS, you could definitely have it write QBJS code and then ask it to run it.

Updated the main program to process multiple messages, so concurrent input seems to work more smoothly. 
Give it a try! Right now it's set up to read input from 8 USB mice plugged into one PC as seperate devices! 

A challenge for you brainiacs: get this working without needing a separate program to read the mice!

Braniac challenge #2: get it to read multiple keyboards as seperate devices! Hint: find the 8800 keys! convert unions in RAWINPUT structure to QB64PE type in "ReadMiceSub"

' Multimouse main program "ReadMiceMain.bas" v0.54
' ################################################################################################################################################################

' -------------------------------------------------------------------------------
' ABOUT
' -------------------------------------------------------------------------------
' Working proof of concept! (Windows only so far)
'
' HOW TO USE:
'
' 1. Plug 2-8 USB mice into your PC.
'
' 2. Place "makeint.h" and "winproc.h" in same folder as the program.
'
' 3. Compile the mouse reader program "ReadMiceSub" first
'    (or run it once, it will run briefly then exit).
'
' 4. Run the front end program "ReadMiceMain".
'    The main program will automatically start the subprogram "ReadMiceSub"
'    which should have the focus.
'
' 5. If your PC prompts for permission say Yes.
'    Be patient, the program takes a few seconds to start everything up
'    and get "situated"!
'
' 6. Click the mouse to make sure "ReadMiceSub" has the focus
'    (it's invisible but sitting on top of "ReadMiceMain").
'
' 7. Try moving each mouse.
'    Each mouse should move a different colored numbered block.
'
' 7. Try clicking the left / middle / right mouse buttons.
'    You should see the button states on the screen for each mouse.
'
' 8. Try pressing some keys on the keyboard.
'    The last keys pressed + released are displayed at the top.
'
' 9. Press Esc to quit, or delete the file "ReadMiceSub.DELETE-TO-CLOSE".
'    The main program creates this file at startup, and both the main and
'    sub programs periodically check that the file is still present.
'    If it is missing, both programs shut down.
'
' DEBUGGING CODE:
' There is currently a ton of commented out debugging code - sorry about the
' mess! There were some horribly elusive problems to figure out.
' To enable debugging output: change Const cDebugEnabled to TRUE
' and search for "debug" and uncomment those lines.
' DebugPrint outputs to the console, DebugLog outputs to a file.
' Enabling console in "ReadMiceSub" caused all sorts of problems,
' so to debug that, just use DebugLog.

' -------------------------------------------------------------------------------
' TO DO
' -------------------------------------------------------------------------------
' Some issues and things to fix:
'
' * Hide the real mouse cursor and reactivate it when program closes.
'
' * Detect moving the scroll wheel.
'
' * Get it working with _FullScreen _SquarePixels.
'   When I tried that mode things got really weird.
'
' * Read input from multiple keyboards - need to figure out how to do the
'   unions in the RAWINPUT structure type in "ReadMiceSub".
'   (Just need someone to figure this out, I have tried.)
'
' * Figure out how to get the same functionality for Mac & Linux.

' -------------------------------------------------------------------------------
' THANK YOU
' -------------------------------------------------------------------------------
' Much credit and thanks are due to:
' * jstookey who started the work that made this possible
' * SpriggsySpriggs who ported the hard stuff (APIs, events) to QB64 & QB64PE
' * SMcNeill who helped with so many things, most recently keeping the main window on top, getting file attributes
' * Steffan-68 for feedback, code for managing windows and ideas
' * DSMan195276 for the network code that lets the reader and main program talk smoothly
' * euklides, Ed Davis, mdijkens for file attributes code
' * grymmjack for words of encouragement
' * the QB64 and QB64PE communities for help with everything
' * (if I forgot anyone let me know!)

' 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.
'                        Code at: https://jstookey.com/multiple-mice-raw-input/
' 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.
' 2024-05-19  madscijr   Try having the program write mice coordinates / button
'                        states to a file that main program "always on top"
'                        without focus can read.
' 2024-05-23  madscijr   Now we get mice coordinates from subprogram via TCPIP.
'                        A lot faster than using files!
'                        Thanks to DSMan195276 for the networking code.
' 2024-06-19  madscijr   Now we get absolute mouse coordinates not just dx, dy
'                        and can read the keyboard (just a single keyboard).
'                        Updated the graphics / display code to use layers.

'SUMMARY:
'   Purpose:  A library of custom functions that transform strings.
'   Author:   Dustinian Camburides (dustinian@gmail.com)
'   Platform: QB64 (www.qb64.org)
'   Revision: 1.6
'   Updated:  5/28/2012

'SUMMARY:
'[Replace$] replaces all instances of the [Find] sub-string with the [Add] sub-string within the [Text] string.
'INPUT:
'Text: The input string; the text that's being manipulated.
'Find: The specified sub-string; the string sought within the [Text] string.
'Add: The sub-string that's being added to the [Text] string.

Function Replace$ (Text1 As String, Find1 As String, Add1 As String)
    ' VARIABLES:
    Dim Text2 As String
    Dim Find2 As String
    Dim Add2 As String
    Dim lngLocation As Long ' The address of the [Find] substring within the [Text] string.
    Dim strBefore As String ' The characters before the string to be replaced.
    Dim strAfter As String ' The characters after the string to be replaced.

    ' INITIALIZE:
    ' MAKE COPIESSO THE ORIGINAL IS NOT MODIFIED (LIKE ByVal IN VBA)
    Text2 = Text1
    Find2 = Find1
    Add2 = Add1

    lngLocation = InStr(1, Text2, Find2)

    ' PROCESSING:
    ' While [Find2] appears in [Text2]...
    While lngLocation
        ' Extract all Text2 before the [Find2] substring:
        strBefore = Left$(Text2, lngLocation - 1)

        ' Extract all text after the [Find2] substring:
        strAfter = Right$(Text2, ((Len(Text2) - (lngLocation + Len(Find2) - 1))))

        ' Return the substring:
        Text2 = strBefore + Add2 + strAfter

        ' Locate the next instance of [Find2]:
        lngLocation = InStr(1, Text2, Find2)

        ' Next instance of [Find2]...
    Wend

    ' OUTPUT:
    Replace$ = Text2

' Given a string of words separated by spaces (or any other character),
' splits it into an array of the words. I've no doubt many people have
' written a version of this over the years and no doubt there's a million
' ways to do it, but I thought I'd put mine here so we have at least one
' version. There's also a join function that does the opposite
' array -> single string.
'
' Code is hopefully reasonably self explanatory with comments and a little demo.
' Note, this is akin to Python/JavaScript split/join, PHP explode/implode.

'Split in$ into pieces, chopping at every occurrence of delimiter$. Multiple consecutive occurrences
'of delimiter$ are treated as a single instance. The chopped pieces are stored in result$().
'
'delimiter$ must be one character long.
'result$() must have been REDIMmed previously.

' Modified to handle multi-character delimiters

Sub split (in$, delimiter$, result$())
    Dim start As Integer
    Dim finish As Integer
    Dim iDelimLen As Integer
    ReDim result$(-1)

    iDelimLen = Len(delimiter$)

    start = 1
    Do
        'While Mid$(in$, start, 1) = delimiter$
        While Mid$(in$, start, iDelimLen) = delimiter$
            'start = start + 1
            start = start + iDelimLen
            If start > Len(in$) Then
                Exit Sub
            End If
        Wend
        finish = InStr(start, in$, delimiter$)
        If finish = 0 Then
            finish = Len(in$) + 1
        End If

        ReDim _Preserve result$(0 To UBound(result$) + 1)

        result$(UBound(result$)) = Mid$(in$, start, finish - start)
        start = finish + 1
    Loop While start <= Len(in$)

'SUMMARY:
'   Purpose:  A library of custom functions that transform strings.
'   Author:   Dustinian Camburides (dustinian@gmail.com)
'   Platform: QB64 (www.qb64.org)
'   Revision: 1.6
'   Updated:  5/28/2012

'SUMMARY:
'[Replace$] replaces all instances of the [Find] sub-string with the [Add] sub-string within the [Text] string.
'INPUT:
'Text: The input string; the text that's being manipulated.
'Find: The specified sub-string; the string sought within the [Text] string.
'Add: The sub-string that's being added to the [Text] string.

Function Replace$ (Text1 As String, Find1 As String, Add1 As String)
    ' VARIABLES:
    Dim Text2 As String
    Dim Find2 As String
    Dim Add2 As String
    Dim lngLocation As Long ' The address of the [Find] substring within the [Text] string.
    Dim strBefore As String ' The characters before the string to be replaced.
    Dim strAfter As String ' The characters after the string to be replaced.

    ' INITIALIZE:
    ' MAKE COPIESSO THE ORIGINAL IS NOT MODIFIED (LIKE ByVal IN VBA)
    Text2 = Text1
    Find2 = Find1
    Add2 = Add1

    lngLocation = InStr(1, Text2, Find2)

    ' PROCESSING:
    ' While [Find2] appears in [Text2]...
    While lngLocation
        ' Extract all Text2 before the [Find2] substring:
        strBefore = Left$(Text2, lngLocation - 1)

        ' Extract all text after the [Find2] substring:
        strAfter = Right$(Text2, ((Len(Text2) - (lngLocation + Len(Find2) - 1))))

        ' Return the substring:
        Text2 = strBefore + Add2 + strAfter

        ' Locate the next instance of [Find2]:
        lngLocation = InStr(1, Text2, Find2)

        ' Next instance of [Find2]...
    Wend

    ' OUTPUT:
    Replace$ = Text2

' Given a string of words separated by spaces (or any other character),
' splits it into an array of the words. I've no doubt many people have
' written a version of this over the years and no doubt there's a million
' ways to do it, but I thought I'd put mine here so we have at least one
' version. There's also a join function that does the opposite
' array -> single string.
'
' Code is hopefully reasonably self explanatory with comments and a little demo.
' Note, this is akin to Python/JavaScript split/join, PHP explode/implode.

'Split in$ into pieces, chopping at every occurrence of delimiter$. Multiple consecutive occurrences
'of delimiter$ are treated as a single instance. The chopped pieces are stored in result$().

'delimiter$ must be one character long.
'result$() must have been REDIMmed previously.

' QB64 GPT Just Rewrote My Code
' https://qb64phoenix.com/forum/showthread.php?tid=2728

' And the revisions QB64 GPT made (after minor changes and me asking it to redo some syntax errors):
' It separated out a lot of processing out to separate subs.
' It is quite impressive how little input I had to give it to fix its mistakes.
' The code actually worked just as well as it did before the changes, which blows my mind.
' It actually even listened to me when I told it that it would need to cast an OFFSET type by using VAL(STR$(var)).
' To be fair, I had to tell it "ByRef" was invalid and a couple of other things.
' I also had to declare "y" each time it was used. But the last iteration only required me to declare "y".
' I think that is a decent enough result. Too bad I can't get it to be this good every time.
' 1) This is the paid version of GPT4. I am on the plus plan, so whatever that one has.
' 2) I think I deleted the session. Sorry. I only used it for as long as I needed it.
' 3) I don't know what the hard limit is. It's in "tokens", which I have no idea how those are calculated.
' I got a pretty large source code from one output and it can take a lot of input. I would just say it can handle quite a bit.
' The GPT I used was one I trained using the Wiki, sample code, etc. At the time, it used GPT4.
' Custom GPTs now use 4o. I will probably need to republish it to take advantage of 4o for it.
' I guess training is the wrong word. A custom GPT has a "knowledge base".
' You can have a maximum of 20 files.
' It can use those files to create an answer. Even a zip folder can be used.
' It will basically only use the knowledge base when specifically asked. Otherwise, it is using whatever it already had in its model.
' As for testing code and such, you can create "actions" for your GPT that allow it to do things outside of ChatGPT, including REST API.
' So if dbox ever made a REST API for QBJS, you could definitely have it write QBJS code and then ask it to run it.
