This question is for anyone using the CADODatabase classes in codeproject.com:

I'm trying to pass a currency amount to a SQL command and keep getting an exception about not declaring scalar variable @Amount.  Any ideas about what is wrong?

    CADORecordset *pRecSet=new CADORecordset(pDB);
    // search for amount $28050.65
    CADOCommand *pCmd=new CADOCommand(pDB, "select itemid from item where amount=@Amount", CADOCommand::typeCmdText);
    COleCurrency currency;
    currency.m_cur.int64=280506500;
    _variant_t vtValue;
    vtValue.vt=VT_CY;
    vtValue.cyVal=currency.m_cur;
    pCmd->AddParameter("@Amount", CADORecordset::typeCurrency, CADOParameter::paramInput, 8, vtValue, 0, 0);
    if(pRecSet->Execute(pCmd)) {
      // exception gets thrown by Execute(pCmd)
    }
    pRecSet->Close();
    delete pCmd;
    delete pRecSet;

typedef int (*callback_fnc)(HWND, int, ...);
my_init_control(HWND hwnd, callback_fnc cb, int flags);

Class A
{
public:
 ...
private:
 int var1;
}

Class B: public A
{
public:
 ...
 void init();
 int proc(HWND hwnd, int msg, ...); // it uses var1 and var2
 ...
private:
 int var2;
}

void B::init()
{
  my_init_control(itemHwnd, B::proc, 0);
}

my_init_control(itemHwnd, boost::bind(&B::proc, this), 0);

B::proc()

B::init()
