You're right. I realized that after posted.
To have it as the machine code would be useful in might-be cases when we're not allowed to install callback.dll.
The best solution, however, will be that Chris implements it into AHK as a built-in function.
I hope Chris take a look at the source code provided by JGR. |

I've tried to apply the asm, but it's not working for me... likely I'm missing something in the structure for the messaging or the callback reception parms. (although shifting over the pointers does seem straightfoward).
very hard for me to debug, as will not run as is, ie. without any wrapping... and inside AHK... no help in debugging...
likely am missing something small (?)... will work some more at it.
YES... maybe Chris will add call back ... would be nice...
Maybe JGR could also strip, assemlble & post the hex...
but even so... the dll sure looks promising... especially for my own personal dream of dll serving..!! [to front end word, for example]

If you need test with ASM/machine code, you may try these.
libtcc.dll posted by Laszlo.
fbsl which has a built-in function CallAbsolute() that can execute a machine code. |

Until callbacks become a built-in feature, I've linked to this topic from the DllCall page.
As for when callbacks will become built-in, I was hoping to do it in a professional, feature-rich way like DllCall. However, that takes considerably more time, which is why it will probably be many months before I get to it. The alternatives to waiting are:
1) Another developer codes the feature (perhaps taking syntax ideas from DllCall).
2) Add a "lite" version of callbacks (perhaps based on this DLL). But even this might take me considerable time to do properly because I don't understand the intricacies and interactions as well as some of you might. |

Hi, Everybody. I'm AHK user.
first, Thanks to JGR.
I have two computers. One is Windows2000pro
and the other is WindowsXpProSp2.
and, I tried first example. (http://www.autohotkey.net/~JGR/callback.rar)
Callback works well on my Windows2000pro. 
But it's not working on my XP. 
I don't know why.
Can someone help me?
test AHK v1.0.46.17
Microsoft Windows XP Pro version2002 ServicePack 2, v.2622 (Korean version)

Hi nnesori,
you should know that an AHK version with buildin callback support is on its way. For more information look here http://www.autohotkey.com/forum/post-127434.html#127434 .
JGR's EnumWindows example would look like this with the experimental AHK version.
| Code: | pid:=DllCall("GetCurrentProcessId","Uint")
DetectHiddenWindows, On
hwnd:=WinExist("ahk_pid " . pid)
EnumWindowsProcStub:= RegisterCallback("EnumWindowsProc","Fast")
GoSub doit
OnExit Tidyup
AppsKey & F11::
doit:
out:=
DllCall("EnumWindows","UInt",EnumWindowsProcStub,"UInt",255)
msgbox, % out
return
EnumWindowsProc(hwnd, lParam) {
global out
;DetectHiddenWindows, On ;Callbacks registered with the "Fast" option inherit global settings
WinGetTitle, text, ahk_id %hwnd%
WinGetClass, class, ahk_id %hwnd%
out.="HWND: ". hwnd . "`tlParam: " . lParam . "`tTitle: " . text . "`tClass: " . class . "`n"
return 1
}
;Tidyness
Tidyup:
DllCall("GlobalFree", "UInt", EnumWindowsProcStub)
ExitApp

Thanks for your response.

Yes, I tried your code with AutoHotkey-RegisterCallback.exe.
But, It only show me a empty messagebox on my WinXPSP2.
Of course, Your posted code works well on my Win2000Pro. |

Try the following code. Still no output in DebugView which I used intead to display the results?
What is the output in the final MsgBox?
| Code: | DetectHiddenWindows, On
MsgBox, % DllCall("EnumWindows", "Uint", RegisterCallback("Window", "Fast"), "Uint", 1) . " | " . ErrorLevel . " | " . A_LastError
Window(hWnd, lParam)
{
WinGetTitle, sTitle, ahk_id %hWnd%
WinGetClass, sClass, ahk_id %hWnd%
OutputDebug, % "hWnd: ". hWnd . "`tTitle: " . sTitle . "`tClass: " . sClass
Return 1
}

Hi, sean.
I tried your posted code.
DebugView result:
No message.
Probably, Window(hWnd, lParam)function not executed.
msgBox result:
---------------------------
t.ahk
---------------------------
| 0xc0000005 | 0
---------------------------
확인
--------------------------- |

This is a memory access violation.
Although I'm not sure if EnumWindows require you to be an admin, are you an admin?
How did you execute the script? Just double clicking it in the explorer?
I.e., actually I suspect this, make sure that there is no other copy of AutoHotkey.exe in your system.
Try save AutoHotkey-RegisterCallback.exe and the script as EnumWindows.ahk in C:\, then execute this:
| Code: | | C:\AutoHotkey-RegisterCallback.exe C:\EnumWindows.ahk |
|

Yes. I am admin.
I renamed original Autohotkey.exe to Autohotkey.bak.
Then, I renamed AutoHotkey-RegisterCallback.exe to Autohotkey.exe
I excute ahk scripts with dynamicReload.exe.
Also, I tested with your suggestion.
| Quote: | | C:\AutoHotkey-RegisterCallback.exe C:\EnumWindows.ahk |
But, Same result.
Thanks for the help anyway. |

Did you execute it directly from the command prompt or Run box, without using secondary some obscure application?
Are you sure that it's not the bug/intererence of the application you used?
From next time you'll report a bug or whatever, be sure you tested it with standard/common way as with other members.
Otherwise, it would make them waste their precious times for nothing, which was likely in this case. |
