[Solved]DirectInput8Create problem

[Frenchy]

Hi, some help will be appreciate!!

I have problem with the call of function DirectInput8Create:

Local $aCall = DllCall($hDINPUT, "long", "DirectInput8Create", "handle", $h , "dword", $DIRECTINPUT_VERSION, "ptr", DllStructGetPtr($pIID), "ptr", $p, "ptr", 0)

I have this error : Pointer that is not valid 0x80004003

the function in C++ is:

HRESULT DirectInput8Create(

HINSTANCE hinst,DWORD dwVersion,REFIID riidltf,LPVOID * ppvOut,LPUNKNOWN punkOuter

)

I think i have an error about the definition of ppvout (LPVOID *)

Parameter before the last one should be defined as:

"ptr*", 0

...Then you read from returned DllCall() array like this:

$p = $aCall[4]

Thanks trancexx for your reply,

i have tested with your modifications which seems good,

Local $aCall = DllCall($hDINPUT, "long", "DirectInput8Create", "handle", $h , "dword", $DIRECTINPUT_VERSION, "ptr", DllStructGetPtr($pIID), "ptr*", 0, "ptr", 0)

but now i have another error -> "0x80004002 -> No such interface supported"

Have you tested the code and no error for you?

I think the param trancexx mentioned, (second to last) is your out param (ppvOut) and should be a pointer to pointer.

Right now you are passing a pointer to riidltf where it does not require one and a null pointer to ppvOut

Hi John,

REFIID structure is long,shor,short,byte[8], so in the dllcall, its necessary a pointer not a value..?

so the problem is always there..

i would use the

_AutoItObject_DllOpen but when i am testing the sample given in the help file..

nothings is functional...???

i have to register or not some dll maybe??

[trancexx]

Docummentation for DirectInput8Create says that third param is IID_IDirectInput8. You are passing IID_IDirectInputDevice8.

I don't see why to be surprised if your call fails.

[Frenchy]

Yes i just see that. stupid error ..you are quicker than me...thanks...all is okay now i have the right return!!..i follow the way...

with :

Global const $sIID_IDirectInput8W = "{BF798031-483A-4DA2-AA99-5D64ED369700}" it s better

Ok. I'm glad you've got it working.

You know, you don't need AutoItObject for this. AutoIt has built-in ObjCreateInterface() funcion that does the job you need much better and simpler.

Thanks Trancexx, i have found the CLSID of dinput8.dll (registry key) and i have the same result ...with less code..
