Callback

[Locodarwin]

I'm eagerly awaiting callbacks. I have several uses for them, and I'm tired of having to write shims in the meantime.

I'm eagerly awaiting callbacks. I have several uses for them, and I'm tired of having to write shims in the meantime.

for what?

maybe i can add it to the examples.

and whats 'shims' ?

updated again see 1'st post.

btw: is there any way to trigger events inside a script without using a windows message?

[Locodarwin]

Well, a good example of an API that I'd like to use callbacks in is the ActiveWorlds SDK. It would be nice to write AW "bots" in AutoIt to cut development time. In particular, the API requires you to install event handlers for specific bot functions.

You're welcome to attempt the feat yourself using your FreeBasic code. It doesn't solve the problem for me because I've already created a shim for it, and your code is really just another shim of sorts. If AutoIt, however, had inborn callback functionality, I wouldn't have to include any shims. That's what I'm looking for, ultimately.

By the way, loosely interpreted, a "shim" in programming parlance (particularly an API shim) is a library that converts one API into another. In the sense we're using here, a shim is code stuck between two APIs to bridge communication between them.

I tryed to write a dll that enables autoit to do callback's

Updated: 06.08.06

Other windows messages can be used to

Commented Example "EnumWindows"

function headers with DllCall Syntax in dll source

This looks really useful! Have you done any more with it? Further documentation, examples, etc?

well thats all for now

i still didnt get it to work with 64bit patameter so i'm still learing asm to do this...

if you want to do something specific i could fix you up an example.

in real geek man

you opened some hell door

thanx alot

Didnt test this with Shutdown only Logoff but...

This can be done without callback:

$WM_QUERYENDSESSION  = 0x11
$WM_ENDSESSION       = 0x16
$hWndDummy = GUICreate("")
$fTrigger = False

GUIRegisterMsg($WM_QUERYENDSESSION,"_Msg")
Func _Msg($hWndGUI, $MsgID, $WParam, $LParam)
    $fTrigger = True
    Return False
EndFunc

While 1
    If $fTrigger Then
        $fTrigger = False
        MsgBox(0,"Shutdown","No you dont!")
    EndIf
    Sleep(250)
WEnd

You code works good, but... shutdown hangs

How can I let shutdown go after doing something (MsgBox in our example)?

Thx for solution, but I'v some problems - AutoIT crashes during Shell API CallBack functions call... This problem fixing by tow steps: declaring MyCallBack function as STDCALL (instead of CDECL) and decreasing count of parameters to actual...

Any ideas?.. May be in addition compile separate function for every count of parameters?.. For example: CallBack01, CallBack02, etc...
