Correct way to create CMap of VARIANTs

Question

I need to create a dictionary collection of VARIANTs using CMap class. My dictionary is defined as such:

CMap<CString, LPCTSTR, CComVariant, CComVariant> map;

I then add elements as such:

void setKeyValue(CMap<CString, LPCTSTR, CComVariant, CComVariant>& map, CString& strKey, VARIANT& varValue)
{
    map.SetAt(strKey, varValue);
}

Can someone check if this is the proper way of populating CMap with VARIANTs? I haven't done COM for a while so I want to make sure that I'm not causing any memory leaks. Thanks!

Answer 1

This will work and is correct.

Important is the use of a CComVariant or _variant_t type that supports correct copying and destruction of Variants.

But why don't you use std::map
