For the next release, JGR has written the code to support built-in callbacks. I also hope to work on the mechanism for the standard library and a built-in Extract/InsertInteger.

In v1.0.46.17, A_UserName was fixed (it had been broken by v1.0.46.16).

Callbacks :?: :P :wink: . Can you tell I'm anxious? :lol:

Thanks a lot for the 1.0.46.16 update and coming callback feature!

In case anyone has time to try it out, here's a test release that contains RegisterCallback():
(Update: The latest release has RegisterCallback.)

Thanks to JGR for developing it.

The documentation is at http://www.autohotkey.com/docs/commands ... llback.htm
Improvements to the documentation or syntax are welcome.

This sample release also contains NumGet() and NumPut(), as well as minor improvements to OnMessage() and Critical.

The next step is to add the stdlib mechanism, after which 1.0.47 will be released.

Hey that is a good idea giving us the chance to test in beta status. So those who want to can help you.

Why don`t you release beta versions on every big change, which would be a critical update?

I will download and test/play some around with that new feature. (can`t wait longer `till stdlib capability)

Thanks for the opportunity to test drive the test version. I'll understand if it isn't but thought I'd ask anyway... Is the source available for the test version?

Thanks for the test build. It works fine so far.
BTW, would Fast mode better be the default?
I suppose most callback functions would work that way.

Code:
DetectHiddenWindows, On
DllCall("EnumWindows", "Uint", RegisterCallback("Window", "Fast"), "Uint", 1)

Window(hWnd, lParam)
{
   WinGetTitle, sTitle, ahk_id %hWnd%
   WinGetClass, sClass, ahk_id %hWnd%
   OutputDebug, % "hWnd: ". hWnd . "`tTitle: " . sTitle . "`tClass: " . sClass . (lParam ? "----------" : "")
   If lParam
   DllCall("EnumChildWindows", "Uint", hWnd, "Uint", A_EventInfo, "Uint", 0)
   Return 1
}

Fantastic! Callbacks work perfectly in the TCClib script (which call the dll version of the Tiny C Compiler, with a C program in an AHK variable.) Error messages and warnings are returned via callbacks. A MsgBox in an AHK function shows now the TCC messages, if they are any.

Thanks for the feedback.

It's a good practice, though sometimes the timing is such that it would significantly delay a release. Fortunately there are other tools such as polls that can help make the right design decisions.

It hasn't been packaged because there may be some polishing done. Also, JGR hasn't had a chance to review and approve the recent syntax changes, nor has the stdlib mechanism been added. 1.0.47 should be out within a week, but if you need it sooner I can put it together and e-mail it to you.

Sean wrote:

Originally it was the default but I intentionally reversed it to make its use a conscious/deliberate decision. If it becomes the default and is ever used by mistake, the script might begin displaying unpredictable behavior that would be very difficult to track down and isolate.

On the other hand, if it's felt that fast mode will be used more than 80% of the time, perhaps the convenience outweighs the risk of accidents.

Also, don't forget that every call to RegisterCallback() creates a new callback address -- even when the target function is the same as that of a previous call. Therefore, scripts should generally avoid calling RegisterCallback() more than once for a particular function (otherwise, it's usually a memory leak).

If it's not too much trouble I'd appreciate it. If it would take a considerable amount of time to put together then I'll wait.

I also tested Sean's keyboard hook script, with low level keyboard handler callback function. It also works perfectly.

It also worked well with SetWinEventHook.
The omission of EVENT_OBJECT_VALUECHANGE (:0x800E) was intentional, as it made DbgView.exe irresponsive.

Code:
hHook := SetWinEventHook(3, 3, pfn := RegisterCallback("WinEvent", "Fast"))
hHook1:= SetWinEventHook(0x8000, 0x800D, pfn)
hHook2:= SetWinEventHook(0x800F, 0x8012, pfn)

DetectHiddenWindows, On
OnExit, Unhook
#Esc::
Unhook:
OnExit
UnhookWinEvent(hHook)
UnhookWinEvent(hHook1)
UnhookWinEvent(hHook2)
ExitApp


WinEvent(hHook, nEvent, hWnd, idObject, idChild, nEventThread, nEventTime)
{
   Critical
   WinGetTitle, sTitle, ahk_id %hWnd%
   WinGetClass, sClass, ahk_id %hWnd%
   OutputDebug, % nEvent . "|" . "`thWnd: ". hWnd . "`tTitle: " . sTitle . "`tClass: " . sClass . "`tidObject: " . idObject . " idChild: " . idChild
}

SetWinEventHook(eventMin, eventMax, pfn)
{
   Return DllCall("SetWinEventHook", "Uint", eventMin, "Uint", eventMax, "Uint", 0, "Uint", pfn, "Uint", 0, "Uint", 0, "Uint", 0)
}

UnhookWinEvent(hHook)

   Return DllCall("UnhookWinEvent", "Uint", hHook)

This works flawlessly, too. Does it mean that we don't need wineventhook.dll any more?

callback.dll,wineventhook.dll & wineventhookq.dll are all superfluous with built in callbacks.
However cbthook.dll still necessary for CBT hooks, as they require dll injection...

I think this answers a common Ask for Help question: "Can I detect another program making a sound?" Please correct me if I'm wrong.
