Returning std::vector<double> using ObjectHandler

[Stale-2]

Hi all, 

I have a function doing some calculations on a vector of doubles, and would like to return a vector (or more correctly a XLOPER structure). For some reason I can't get this simple test-code to work:

DLLEXPORT OPER *VectorTest(

OPER *Indata) {

boost::shared_ptr<ObjectHandler::FunctionCall> functionCall;

    try {

                std::vector<double> values=ObjectHandler::operToVector<double>(*Indata, "Indata");

std::vector<double> outdata;

for(int i=0; i<values.size(); i++) outdata.push_back(values[i]);

static OPER xRet;

ObjectHandler::vectorToOper(outdata, xRet);

                return &xRet;

    } catch (...) {

        return 0;

    }

}

All compiles and linkes nicely, and the add-inn seems to work, but Excel complains about #NUM when I try it.

All input appreciated!

Thanks!

Bjørn

Hi Bjorn,

> OPER *Indata) {
>

>
>     try {

At this point in the code - first thing within the try block - you
should say:

functionCall = boost::shared_ptr<ObjectHandler::FunctionCall>(
  new ObjectHandler::FunctionCall("VectorTest"));

> Excel complains about #NUM when I try it.

Please show us the code you use to register the function with Excel.

Kind Regards,
Eric
