Unicode Data transfer Using Mysql by C++

Yes I was connecting in MYSQL.I got the solution
1) in connection String i have set charset=utf8;
EX : bsConnectionString = "Driver={MySQL ODBC 3.51 Driver};Server=localhost;Database=mydatabase;Uid=root;Pwd=amit;charset=utf8;pooling=false;";
2) data value what i was geting as wstring 1st i converted into utf8 string then again to wstring so things are working fine
EX:
// For MYSQL DataBase wString Need to convert In UTF8
if((m_pAdo->GetProviderType()== MYSQL)&&(varValue.vt == VT_BSTR))
{
wsValue = strtowstr(ToUtf8(wsValue));
}
td::string ToUtf8(const std::wstring& widestring)
{
int utf8size = ::WideCharToMultiByte(CP_UTF8, 0, widestring.c_str(), -1, NULL, 0, NULL, NULL);
if ( utf8size == 0)
{
throw std::exception("Error in conversion.");
}

std::vector<char> resultstring(utf8size);

int convresult = ::WideCharToMultiByte(CP_UTF8, 0, widestring.c_str(), -1, &resultstring[0], utf8size, NULL, NULL);
if (convresult != utf8size)
{
throw std::exception("La falla!");
}

return std::string(&resultstring[0]);
}


std::wstring strtowstr(const std::string &str)
{ // Convert an ASCII string to a Unicode String
std::wstring wstrTo;
wchar_t *wszTo = new wchar_t[str.length() + 1];
wszTo[str.size()] = L'\0';
MultiByteToWideChar(CP_ACP, 0, str.c_str(), -1, wszTo, (int)str.length());
wstrTo = wszTo;
delete[] wszTo;
return wstrTo;
}
