MQSendMessage throwing exception for simple "hello world" example. I am trying to write a simple send/receive for a private queue, nothing fancy.(non-transactional, events, etc) just simple strings. Queue is created successfully

code:

int sendMsg(std::string message, QUEUEHANDLE queuePtr)
{
	HRESULT status;

		MQMSGPROPS msgProperties;
		const int NUMBEROFPROPERTIES = 2;
		WCHAR tmpBodyMsg[] = L"RISQ first message";

		MSGPROPID msgPropertyID[NUMBEROFPROPERTIES];
		MQPROPVARIANT msgPropertyVariant[NUMBEROFPROPERTIES];
		HRESULT msgStatus[NUMBEROFPROPERTIES];


		int propIndex = 0;

		DWORD bodyType = VT_BSTR;
		msgPropertyID[propIndex] = PROPID_M_BODY_TYPE;
		msgPropertyVariant[propIndex].vt = VT_UI4;
		msgPropertyVariant[propIndex].ulVal = bodyType;
		propIndex++;

		msgPropertyID[propIndex] = PROPID_M_BODY;
		msgPropertyVariant[propIndex].vt = VT_VECTOR | VT_UI1;
		msgPropertyVariant[propIndex].caub.pElems = (LPBYTE)tmpBodyMsg;
		msgPropertyVariant[propIndex].caub.cElems =	sizeof(tmpBodyMsg);
		propIndex++;		


		// intialize MQQUEUEPROPS structure
		msgProperties.cProp = propIndex;
		msgProperties.aPropID = msgPropertyID;
		msgProperties.aPropVar = msgPropertyVariant;
		msgProperties.aStatus = msgStatus;


		status = MQSendMessage(queuePtr, &msgProperties, NULL);
		if(status != MQ_OK)
