Hi there!
 
I need to take differents types of data, like:
 
int n = 12; //plus
short int n1 = 255; //plus
unsigned char b = 4; //plus
unsigned short w = 1600;
std::string str = "SR_protocol";
 
put all togheter in a CComSafeArray<BYTE>, and convert it to send in a COM object (OPC), like:
 
CComSafeArray<BYTE> saByteArray;
CComVariant varArrayWrapper(saByteArray);
VARIANT *vSendMSG = NULL;
varArrayWrapper.Detach(vSendMSG);
 
But I don't know how to do it.. help me please
