I tried the same thing but didn't got any error. Thus, if you can please share the code snippet, we may provide some inputs.

Use this code using std::vector; Thanks Bhawna

Hi Put this code using namespace std; instead of using std::vector; using std::copy; using std::iterator; using std::string; and I hope it works fine. Warm Regards Bhawna

Use itoa() to convert long/int to char* and append this to CcomBSTR as in the given sample code: LPARAM temp = 90; CComBSTR t; char* buf= new char[5]; buf = itoa(temp,buf,10); t.Append(buf); Cheers!! Bhawna
