We are making some tests with facial recognition devices and the protocol is implemented using the HwDevComm.dll.
One possibility was to connect these devices to our application made ??in WINDEV.
So far we can not start any communication, always some GPF error in the dll.

I had some GPF, but it gone adding CALLBACK on my typedef declarations...

typedef int ( CALLBACK FuncTotalDoneTp ) ( unsigned long nTotal, unsigned long nDone );
typedef int ( CALLBACK * CALL_HwDev_Execute )( char * pDevInfoBuf, unsigned long nDevInfoLen, char * pSendBuf, unsigned long nSendLen, char ** pRecvBuf, unsigned long * pRecvLen, FuncTotalDoneTp pFuncTotalDone );
typedef void ( CALLBACK * CALL_HwDev_Finish ) ( char ** pRecvBuf );


Atte.
