Till Vacum,
Jag har tagit bort alla andra asio drivers och nu har jag enbart en version av det.
Ändå kvarstår problemmet.
För att komma åt dll filen så anger jag enbart sökvägen på följande sätt
#define ASIO_PATH "C:\Documents and Settings\VERA362\MyDocuments\
ASIO\SDK\host\asio4all.dll"
Är det fel sätt att försöka komma åt dll:en, hur skull man annars göra det.
Nedan är koden:
#include <windows.h>
#include "iasiodrv.h"
#include "asiolist.h"
#include "stdio.h "
#define ASIODRV_DESC "description"
#define INPROC_SERVER "InprocServer32"
#define ASIO_PATH "C:\Documents and Settings\VERA362\My Documents\ASIO SDK\host\asio4all.dll" //"software\\asio"
//#define ASIO_PATH "asio4all.dll" //"software\\asio"
#define COM_CLSID "clsid"
