Overflow error when call Ubound method

[wallaceoc80]

Hi, I am getting an "Overflow" error when I call Ubound on an object of type Variant

numResult = UBound(result)

I have tried doing some searching on the net and I can't figure this one out. Has anyone ever encountered this before? The result object looks to be ok when I check it in debug mode.

Thanks,
Wallace

>looks to be ok

In what sense?

Some more info that might help. result object is a class that I have created as follows:

class HedgeResult
    {
        friend std::ostream & operator<<(std::ostream &, const HResult &);

    public:
        void clear();

        struct Result
        {
            std::string resultError;
            std::string ise;
            std::string desc;
            double position;
            double stub;
            double dve;
            std::vector<double> hr;
        };

        std::string globalError;
        std::vector<std::string> fNames_;
        std::vector<double> fPrs_;
        std::vector<std::string> fDates_;
        std::vector<Result> results_;
    };

By it looks OK I mean that the results_ vector in the struct has 774 items when I looked at it in debug mode and all the other members of the struct are set OK.

Does this help?

Thanks,

From the VB code, it looks like you are anticipating an SAFEARRAY to be returned as the default mathod of your class. On the other hand there is nothing in your C++ code to suggest that this is the case ...

I figured out what was happening. Ubound returns a long and I was assigning the returned value to an Integer. This was ok some of the time but when a larger number was returned it caused the overflow.

Thanks for your suggestions.
