When I use DllCallbackRegister zero is returned and @error is set to three.  The helpfile doesn't explain the @error.  Searching the forum reveals that no one else seems to have this same problem as far as I could see.  Here is my code:

#AutoIt3Wrapper_AU3Check_Parameters=-w 1 -w 2 -w 3 -w 4 -w 6 -w 7 -d

#include <Misc.au3>

_Singleton(@ScriptName)

#include <WinAPI.au3>

Global Const $hStub_MouseProc = DllCallbackRegister("_Mouse_Proc", "int", "int;ptr;ptr")

Switch $hStub_MouseProc
    Case 0
        ConsoleWrite("$hStub_MouseProc: " & $hStub_MouseProc & " @error: " & @error & @CRLF)
        Exit
EndSwitch

Global Const $hHook = _WinAPI_SetWindowsHookEx($WH_MOUSE_LL, DllCallbackGetPtr($hStub_MouseProc), _WinAPI_GetModuleHandle(0))

OnAutoItExitRegister("cleanup")

Do
    Sleep(10)
Until False

Func _Mouse_Proc(Const $nCode, Const $wParam, Const $lParam)
    Switch $nCode >= 0
        Case True
            ConsoleWrite("$nCode: " & $nCode & @CRLF)
    EndSwitch

    Return _WinAPI_CallNextHookEx($hHook, $nCode, $wParam, $lParam)
EndFunc

Func cleanup()
    _WinAPI_UnhookWindowsHookEx($hHook)
    DllCallbackFree($hStub_MouseProc)
EndFunc

Try... '_Mouse_Pro', 'long', 'int;wparam;lparam' as stated on MSDN.

jaberwocky,

As guinness advised

#AutoIt3Wrapper_AU3Check_Parameters=-w 1 -w 2 -w 3 -w 4 -w 6 -w 7 -d

#include <Misc.au3>

_Singleton(@ScriptName)

#include <WinAPI.au3>

Global Const $hStub_MouseProc = DllCallbackRegister("_Mouse_Proc", "int", "int;ptr;ptr")

Switch $hStub_MouseProc
    Case 0
        ConsoleWrite("$hStub_MouseProc: " & $hStub_MouseProc & " @error: " & @error & @CRLF)
        Exit
EndSwitch

Global Const $hHook = _WinAPI_SetWindowsHookEx($WH_MOUSE_LL, DllCallbackGetPtr($hStub_MouseProc), _WinAPI_GetModuleHandle(0))

OnAutoItExitRegister("cleanup")

Do
    Sleep(10)
Until False

Func _Mouse_Proc($ncode,$wParam,$lParam)
    Switch $nCode >= 0
        Case True
            ConsoleWrite("$nCode: " & $nCode & @CRLF)
    EndSwitch

    Return _WinAPI_CallNextHookEx($hHook, $nCode, $wParam, $lParam)
EndFunc

Func cleanup()
    _WinAPI_UnhookWindowsHookEx($hHook)
    DllCallbackFree($hStub_MouseProc)
EndFunc

I've never seen anything like this.  It works with Kylomas' example.  I've done it like this before.  When I modify original script to match Kylomas' it doesn't work.  Yet, when I copy and paste Kylomas' script then it works.

Thanks for the help!

Here is the latest version of my script that did not work:

#AutoIt3Wrapper_AU3Check_Parameters=-w 1 -w 2 -w 3 -w 4 -w 6 -w 7 -d

#include <Misc.au3>

_Singleton(@ScriptName)

#include <WinAPI.au3>

Global Const $mouse_proc_callback = DllCallbackRegister("_Mouse_Proc", "int", "int;ptr;ptr")

Switch $mouse_proc_callback
    Case 0
        ConsoleWrite("$mouse_proc_callback: " & $mouse_proc_callback & " @error: " & @error & @CRLF)
        Exit
EndSwitch

Global Const $hook = _WinAPI_SetWindowsHookEx($WH_MOUSE_LL, DllCallbackGetPtr($mouse_proc_callback), _WinAPI_GetModuleHandle(0))

OnAutoItExitRegister("cleanup")

Do
    Sleep(10)
Until False

Func _Mouse_Proc(Const $code, Const $w_param, Const $l_param)
    Switch $code >= 0
        Case True
            Switch $w_param
                Case $WM_LBUTTONDOWN
                    ConsoleWrite("$WM_LBUTTONDOWN" & @CRLF)

                Case $WM_LBUTTONUP
                    ConsoleWrite("$WM_LBUTTONUP" & @CRLF)

                Case $WM_MOUSEMOVE
                    ConsoleWrite("$WM_MOUSEMOVE" & @CRLF)

                Case $WM_MOUSEWHEEL
                    ConsoleWrite("$WM_MOUSEWHEEL" & @CRLF)

                Case $WM_MOUSEHWHEEL
                    ConsoleWrite("$WM_MOUSEHWHEEL" & @CRLF)

                Case $WM_RBUTTONDOWN
                    ConsoleWrite("$WM_RBUTTONDOWN" & @CRLF)

                Case $WM_RBUTTONUP
                    ConsoleWrite("$WM_RBUTTONUP" & @CRLF)
            EndSwitch

            Return 0
        Case False
            Return _WinAPI_CallNextHookEx($hook, $code, $w_param, $l_param)
    EndSwitch
EndFunc

Func cleanup()
    _WinAPI_UnhookWindowsHookEx($hook)
    DllCallbackFree($mouse_proc_callback)
EndFunc

Compared to Kylomas' version that does work:

#AutoIt3Wrapper_AU3Check_Parameters=-w 1 -w 2 -w 3 -w 4 -w 6 -w 7 -d

#include <Misc.au3>

_Singleton(@ScriptName)

#include <WinAPI.au3>

Global Const $hStub_MouseProc = DllCallbackRegister("_Mouse_Proc", "int", "int;ptr;ptr")

Switch $hStub_MouseProc
    Case 0
        ConsoleWrite("$hStub_MouseProc: " & $hStub_MouseProc & " @error: " & @error & @CRLF)
        Exit
EndSwitch

Global Const $hHook = _WinAPI_SetWindowsHookEx($WH_MOUSE_LL, DllCallbackGetPtr($hStub_MouseProc), _WinAPI_GetModuleHandle(0))

OnAutoItExitRegister("cleanup")

Do
    Sleep(10)
Until False

Func _Mouse_Proc($ncode,$wParam,$lParam)
    Switch $nCode >= 0
        Case True
            ConsoleWrite("$nCode: " & $nCode & @CRLF)
    EndSwitch

    Return _WinAPI_CallNextHookEx($hHook, $nCode, $wParam, $lParam)
EndFunc

Func cleanup()
    _WinAPI_UnhookWindowsHookEx($hHook)
    DllCallbackFree($hStub_MouseProc)
EndFunc

 This seems like high strangeness to me.

I can see the problem, instead of Return 0 you should be calling the next hook. Also my advice still stands correct. You should ideally change it to that.

OK, it was because I was setting the parameters for _Mouse_Proc to Const!

 

Yes, was that not obvious?   The MSDN doc is very specific about how and when to return and/or call the next hook.  Have you read it?

I did see the Const and of course wondered that too, but didn't think it would make a blind bit of difference as they're being passed as values and not a references.

Hmmm...communication fails miserably in this medium...

What I was thinking when I posted that was that I should have pointed this out specifically.  When I re-read it I was afraid that you would take it critically.

The return comment refers specifically to what guinness is warning you about.

edit: additional info

 I don't see why I can't set the parameters to my own UDF to Const though.

 

 

Because CONST vars cannot change, the parms to this procedure change with every call.

I did take it critically but now I see that wasn't your intent.  I think that maybe CallNextHookEx modifies the parameters internally now that I realize what you mean.

Both of you helped very much.  I'm torn on which post to mark.

I went with #4 because he mentioned your contribution.

Probably neither.

No, it isn't obvious.  Chill please.  I don't see why I can't set the parameters to my own UDF to Const though.

"The MSDN doc is very specific about how and when to return and/or call the next hook.  Have you read it?" 

What does that have to do with setting parameters to const?

AutoIt doesn't allow the use of any keywords (const, byref, ...) for callback functions parameters.
