setQuoteToDB' : cannot convert parameter 1 from 'const char *' to 'unsigned short ** '

You are passing LPCTSTR in place of BSTR*. Convert LPCTSTR to BSTR by using

USES_CONVERSION;
BSTR b =A2BSTR(lpszText);//lpszText is LPCSTR

and pass it address to wherever BSTR* is required.

setQuoteToDB(Timestamp,marketno,Market,ask_d,bid_d,marketstate

This call would go like,

USES_CONVERSION;
BSTR bsTimeStamp = A2BSTR(Timestamp);
BSTR bsMarket = A2BSTR(Market);
BSTR bsBid = A2BSTR(Bid);
BSTR bsAsk = A2BSTR(Ask);
setQuoteToDB(&bsTimeStamp,&marketno,&bsMarket,&bsAsk,&bsBid,&marketstate);
// in above call short* parameter will go as it is
SysFreeString(bsTimeStamp);
SysFreeString(bsMarket);
SysFreeString(bsBid);
SysFreeString(bsAsk);

To make others solve your problem, you need to give complete/clear problem definition. You can convert CString to BSTR using CString::AllocSysString().

Second parameter is short*, you need to pass address of MarketNo. Your call would be like ;

setQuoteToDB(&bsTimeStamp,&MarketNo,&bsMarket,&bsAsk,&bsBid,&marketstate);
