well, now this is part of the code :

this->Info->alGenEffects = (LPALGENEFFECTS) alGetProcAddress("alGenEffects");


this->Info->alDeleteEffects = (LPALDELETEEFFECTS) alGetProcAddress("alDeleteEffects");


this->Info->alIsEffect = (LPALISEFFECT) alGetProcAddress("alIsEffect");


this->Info->alGenAuxiliaryEffectSlots = (LPALGENAUXILIARYEFFECTSLOTS) alGetProcAddress("alGenAuxiliaryEffectSlots");

and Info gots this members :

LPALGENEFFECTS alGenEffects;

LPALDELETEEFFECTS alDeleteEffects;

LPALISEFFECT alIsEffect;

LPALGENAUXILIARYEFFECTSLOTS  alGenAuxiliaryEffectSlots;

the code points the problem here =/ :

if (!(this->Info->alGenEffects && this->Info->alDeleteEffects && this->Info->alIsEffect && this->Info->alGenAuxiliaryEffectSlots)) this->Installed = -2;

this->Error = alGetError();

if (this->Installed<0) return -3;

what happens ? well alGenEffects,alDeleteEffects,alIsEffect and alGenAuxiliaryEffectSlots are equal to NULL, so, the problem is that something is not working with alGetProcAddress() ..
and this is getting me crazy xD
Error have the value of 0, so, alGetError tell me thats its all fine when not ..

so, if somebody can give me a clue, i will apreciate it so much ^.^

Au Revoir !

Hello L1zb3th!

To get valid functionpointers from alGetProcAddress, the context has to be made the current context, before using alGetProcAddress

alcMakeContextCurrent(yourContext);

After successfully calling this function, you will receive valid pointers.

Happy Coding

i will check that ^^
i think the Context was initialized =/
umhhhhh....
i will see what happen ^^
Au Revoir !

EDIT: i forgot, Skaldi, thank you so much ^^

Hello L1zb3th!

Did u have luck with alGetProcAddress?

Happy Coding
