Using GetObjectByGuid in Process

[ziinus]

Hi every one,

I'm trying to use getobjectbyguid in process with my injected dll hooking endscene.

here is my code

typedef DWORD_PTR (__cdecl * tGetObjectByGuid)(unsigned __int64 Guid, int a1);
tGetObjectByGuid oGetObjectByGuid = reinterpret_cast<tGetObjectByGuid>(0x007BE110);

and i'm using it like this :

DWORD_PTR ObjectReturned = oGetObjectByGuid(LocalGuid,1);

Where LocalGuid is a unsigned __int64. ( I've checked and it contains the right value )


But the function seems to always return 0, no wow crash nothing but 0 ^^

Does anaybody know where i'm wrong and can show me the right direction ?
I've searched but didn't found a topic where it was called in process.


Thanks

I solved id thank you, i'm really Dumb =D

Was putting the wrong value into LocalGuid...


Anyway, if it helps somebody :

// GetObjectByGuid
typedef DWORD_PTR (__cdecl * tGetObjectByGuid)(unsigned __int64 Guid);
tGetObjectByGuid oGetObjectByGuid = reinterpret_cast<tGetObjectByGuid>(0x007BE110);

and

DWORD_PTR ObjectedReturned = oGetObjectByGuid(LocalGuid);

Works when you call it in the main thread

Try setting the filter arg to -1. This is how the function is called in WoWX:

CGObject_C * CGCurMgr_C::GetObjectByGUID( WGUID wGuid )
{
	typedef CGObject_C * ( __cdecl * tGetObjectByGUID )( WGUID wGuid, int dwFilter );
	tGetObjectByGUID oGetObjectByGUID = reinterpret_cast<tGetObjectByGUID>( gpWoWX->GetFindPattern()->GetAddress( "GetObjectByGUID" ) );

	return oGetObjectByGUID( wGuid, -1 );
}
