Question

First of all I know that the question was already asked here :

return multi dimension array to excel from c++ xll

I have tried to revive the subject, without suc

Answer 1

A simple example returning a 5*5 matrix. Don't forget to free the allocated array via the xlAutoFree12 function.

__declspec(dllexport) LPXLOPER12 WINAPI Get2DArray(void)
{   
    static XLOPER12 xlArray;
    int rows = 5;
    int cols = 5;
    xlArray.xltype = xltypeMulti | xlbitDLLFree;
    xlArray.val.array.rows = rows;
    xlArray.val.array.columns = cols;
    xlArray.val.array.lparray = reinterpret_cast<LPXLOPER12>(::malloc(rows * cols * sizeof(XLOPER12)));
    for (int r=0;r<rows;r++)
    {
            for (int c=0;c<cols;c++)
            {
                XLOPER12* var = xlArray.val.array.lparray + ((r* cols) + c);
                var->xltype = xltypeNum;
                var->val.num = r*c;
            }
    }
    return &xlArray;
}
