How to build a SAFEARRAY of pointers to VARIANTs?
c++, com, safearray, variant
Solution
Adding to the answers above for reference by future readers: In IDL, `SAFEARRAY(...)` means a pointer to an array descriptor. But in C++, `SAFEARRAY` means an array descriptor. So IDL's `SAFEARRAY(...)` is really C++'s `SAFEARRAY *`. This confused me to no end. To make things even more interesting, VB always passes arrays by reference. So VB's `() As Long` is `SAFEARRAY<int32_t> **` in C++. (I don't know if there actually is a commonly used header that allows you to specify the type as a template parameter, but I inserted it for clarity.)
Problem
I'm trying to use a COM component with the following method: ``` HRESULT _stdcall Run( [in] SAFEARRAY(BSTR) paramNames, [in] SAFEARRAY(VARIANT *) paramValues ); ``` How can I create in C/C++ the paramValues array?
