[Solved]Callback function and Objet

6 posts in this topic

#1 ·  Posted (edited)


I follow my project about the use of DirectInput with Autoit

If i can create the interface correctly with the DirectInput8create Function

I have a problem when i want to use Callback function to enum Devices. ("bad callee")

i have Written this piece of code, but is it the the good syntax to callback the function _EnumJoystickProc?

i have looked in this forum and Google, but no samples of code using callback and Objet, may be its no possible?

Or there is a special syntax to callback function with autoit objet?

Local $oDirectInput8 = ObjCreateInterface ( $sCLSID_DirectInput8 , $sIID_IDirectInput8 ,$dtagIDirectInput8 )
; Create callback function
Global $handle = DllCallbackRegister("_EnumJoystickProc", "BOOL", "ptr;ptr")
$aa=$oDirectInput8.EnumDevices($DI8DEVCLASS_ALL,DllCallbackGetPtr($handle), 0, $DIEDFL_ATTACHEDONLY)
; MsgBox(0,hex($aa,8),$oDirectInput8)
Func _EnumJoystickProc($pDIinstance, $pContexte)
     Return $DIENUM_STOP

You should post runnable code if you want precise help. Ten things could be wrong with the code that you aren't posting.

What I can see in your posted code is that you don't initialize DirectInput object. If you use ObjCreateInterface() then you have to call Initialize method before you start working with the object. It's all there on MSDN page for DirectInput8Create, just read carefully.

Okay Trancexx, i have poste a runnable code (sorry for my english..)

So when i try to initialize the DirectInput interface

i have this com error: ! COM Error ! Number: 0x80020010 - Invalid Callee

So i have tried to understand.. iahev redad MSDM to understand better COM objet, so the objet interface to be correctly created, but Initialize Fails..

the function in C++ gives

HRESULT Initialize(


DWORD dwVersion


But when i test the VarGetType of Handle of Dll ($hDINPUT) it says Int32, but in help Autoit, Handle is pointer.. Dunno if the cause of error..

I need some light...!!

It should be:

$oDirectInput8.Initialize(_WinAPI_GetModuleHandle(0), $DIRECTINPUT_VERSION)

And lose $dtagIUnknown. IUnknown methods are added by AutoIt internally (read documentation for ObjCreateInerface).

Other than that your code is fine.

Okay Trancexx i understant better the sentence in help file about the 3 methods automatically added in Objet COM, and i understand why my program fails (certainly an offset problem with function)

i have to increase my skills in english langage !!

Thanks again for your time to help me..With Com objet i have discovered a part of autoit i have never opened!!

In fact all is possible with Autoit!!

i really appreciate

      Hey everyone,
      I searched some hours for a way to use the function WaitForSingleObject not as a function the script has to wait for, but a function which calls a callback function when the event is signaled. I found a way with RegisterWaitForSingleObject  but no AutoIt implemention, so I made one on my own, and now I want to share it with you guys!
      The only limitation by this implemention is that you are not able to use more than one callback at once. to avoid this, you could write a static array in the function which fills with the selfmade callback structs. If you find another way, let me know!

      Hope you like it and find use for it!

      Hello all,
      Back again it seems. I've hit a snag in the below script. I use this on win 7 and XP machines frequently and have just realized that sorting using column headers is not 'working' (is not updating listview; it looks like something is going on behind the scenes..) when clicked. Also this does not show the sorting arrow when using the callback sort functionality.
      So, to sum up, I am not seeing the arrow keys when clicking the column header to sort. And, it is not sorting the values in the $List1 ListView box on a win XP machine.

      Hey folks,
      I just explored the new helpfile and found a new Keyword (dunno if its that new, but i never saw it before) called Volatile. It was made especally for CallBack and Com event functions, so I wanted to try that out. the advantage of this Keyword is, that you can run the Dll while you can do other things in autoit (AutoIt wont freeze/pause anymore while the dllcall is executed!)
      I made up a little example i want to share with you, the c source is compiled in MinGW, you need at least AutoIt
      Hope you like it, would be interested in some comments

      I wanted to see if I could manage to use IAppVisibility (Win8) in one of my scripts.
      (it seems the name was changed in Release Preview but MSDN wasn't updated)

      It took some time but I learned to make tlb file and made definitions for GetAppVisibilityOnMonitor and IsLauncherVisible methods (working good as far as I can tell), but I would like Advise and Unadvise too if possible, but I don't know how...

      See definition on above link.

      Only example I found is some (too advanced for me to translate) c++ code. Here. But it compiles and runs fine at least.

      trancexx is doing a similar thing in maybe that can be used somehow?

      Anyone have a clue?

      Test script with the working funcs:

      #include <WinAPI.au3> ;=============================================================================== #interface "IAppVisibility" Global Const $sCLSID_AppVisibility = "{7E5FE3D9-985F-4908-91F9-EE19F9FD1514}" Global Const $sIID_IAppVisibility = "{2246EA2D-CAEA-4444-A3C4-6DE827E44313}" ; Definition Global Const $tagIAppVisibility = "GetAppVisibilityOnMonitor hresult(ptr;int*);" & _ "IsLauncherVisible hresult(int*);" & _ "Advise hresult(ptr;dword*);" & _ "Unadvise hresult(dword);" ;============================================================================== Local $oAppVisibility = ObjCreateInterface($sCLSID_AppVisibility, $sIID_IAppVisibility, $tagIAppVisibility) ;~ MsgBox(0, @ScriptName, IsObj($oAppVisibility)) ;~ ConsoleWrite(IsObj($oAppVisibility) & @CRLF) If Not IsObj($oAppVisibility) Then ConsoleWrite("NOT IsObj" & @LF) MsgBox(0, "", "NOT IsObj") Exit EndIf HotKeySet("ö", "_IsLauncherVisible") HotKeySet("å", "_GetAppVisibilityOnMonitor") $oMyError = ObjEvent("AutoIt.Error", "ErrFunc") ; Install a custom error handler $callback=DllCallbackRegister("_MonitorEnumProc","int","ptr;ptr;ptr;lparam") Global $Monitor DllCall("user32.dll","int","EnumDisplayMonitors","ptr",0,"ptr",0,"ptr",DllCallbackGetPtr($callback),"lparam",10) While 1 Sleep(1000) WEnd Func _IsLauncherVisible() Local $bVisible $iRet = $oAppVisibility.IsLauncherVisible($bVisible) ;~ If @error Then ;Enable this and disable AutoIt.Error if on Alpha ;~ MsgBox(0, @ScriptName, @error) ;~ EndIf ToolTip("1: " & $iRet & @CRLF & "2: " & $bVisible) EndFunc Func _GetAppVisibilityOnMonitor() Local $iMode $iRet = $oAppVisibility.GetAppVisibilityOnMonitor($Monitor, $iMode) ToolTip("1: " & $iRet & @CRLF & "2: " & $iMode) EndFunc ; This is a custom error handler Func ErrFunc() $HexNumber = Hex($oMyError.number, 8) MsgBox(0, "", "We intercepted a COM Error !" & @CRLF & _ "Number is: " & $HexNumber & @CRLF & _ "WinDescription is: " & $oMyError.windescription) $iEventError = 1 ; Use to check when a COM Error occurs EndFunc ;==>ErrFunc Func _MonitorEnumProc($hMonitor, $hdcMonitor, $lprect, $lparam) MsgBox(0, "Monitor", "Monitor handle: " & $hMonitor & @CRLF & "LPARAM: " & $lparam) $Monitor = $hMonitor EndFunc
