    Passing array of doubles to ATL COM dll

    Hi,
    I'm developing a DLL Atl com. I want pass as parameter one array of doubles.

    I read the best form to do it is with VARIANT* parameter in C++ and manage ir as SAFEARRAY. But It seems very complicated.

    It is the best form to do it? How do you pass array of doubles?
    Thanks

    You just want to pass a double array to a function? Try this prototype:
    Code:
    void take_double_array(double array[], size_t array_length);
    You can use something other than size_t if you want.

    Not to a simple function. To a function in a atl dll.
    Thanks

    SAFEARRY is probably the only way to do it. There are some articles on www.codeproject.com about it. type in "safearray" in their search engine and you will get a list of articles
